Remove gtk_menu_popup_for_device() and gtk_menu_popup(), as they cannot
be implemented in a portable manner by all backends. They have been
deprecated for proper alternative APIs for some time, so lets remove
them now before its too late.
While at it, fix the example documentation for mapping a menu.
This is a temporary measure to make the check-icon-names
test not fail in ci. We still have to figure out the best
way to include a core icontheme with GTK+.
GLib master propagates argument types in g_clear_pointer(), which causes
the usual function pointer casts to GDestroyNotify to trip compiler
warnings. Additionally, this commit changes some cleanup functions where
appropriate (wl_data_source_destroy ->
gtk_primary_selection_source_destroy for struct
gtk_primary_selection_source).
GtkEntryCompletion can rapidly release and claim ownership of the
primary selection. This generates multiple XFixesSelectionNotify events,
first stating that no one owns the selection, then another stating that
we own the selection. The notification that no one owns the selection
causes GtkEntryCompletion to deselect the text, breaking inline
autocompletion.
This fixes it by ignoring any XFixesSelectionNotify with a timestamp
earlier than our clipboard timestamp.

file_uri_deserializer splices a memory stream, as opposed to
string_deserializer, which uses a converter and filter stream. This
commit fixes erroneous use of GMemoryOutputStream as
GFilterOutputStream.
Since the function is usually called from GtkWidget::drag-{begin,end} handlers,
taking a GdkDrop does not work, especially given that
::drag-action-requested is emitted without checking the type.
Fixes https://gitlab.gnome.org/GNOME/gtk/issues/1220
The previous attempt at removing configure events entirely
was causing some dialogs not to show up under Wayland.
Presumably due to ordering issues with emitting ::size-change
out of the backend.
Instead, keep configure events in the event queue, but handle
them on the gdk side. This keeps the ordering intact, while
still removing configure events from the api. The dialogs
show up now.
The opaque region is only set when the background color is opaque. So
we need to do something about it when the background color changes.
However, in the case where a size allocation is going to happen, we
already do this update in size_allocate(), so in that case avoid doing
it twice.
Instead of instantly invalidating, we now cache the old render node and
do the update in an idle handler.
While that gives us a 1 frame delay, it avoids all the tricky things
like queueing resizes while resizing or queueing draws while drawing.
The only remaining issue (and a *big* one at that) is that a nested
widget paintable will now cause the widget to snapshot its previous
render node when creating a new one. And that one will snapshot its
previous render node, and that one will...
And nothing so far breaks this recursion.
Change GdkDrag::action to GdkDrag::selected-action, which is
more clearly different from actions, and follows the existing
name of the struct field and getter.
This lets us drop the ::action-changed signal for the
property change notification. But, can just as well move
the signal class handers which just update the cursor
to the ::action setter. No need to do this in the backends.
Some of the _diff implementations did a whole bunch of work just to
throw it away afterwards and invalidate the entire union of the two
render nodes, most notably the two clip nodes. Fix this to only call
gsk_render_node_diff_impossible if the previous if-condition is FALSE
and not always.
This is still fallout from the bin_window removal. We aren't moving the
GdkWindow/GdkSurface anymore so we have to account for the scrolling
ourselves.
Since those are widgets and widgets need to be size-allocate'd properly,
we need to queue an allocate, as well as actually add the hadjustment's
value to the column x position.
Fixes#1202
The purpose of a searchbar is to start a search on visible widgets when
a key is pressed. Starting a search on e.g. a stack page that is not
visible at all is not very useful.
... if none of the debug displays have any debug flags set. This way, we
can ignore the first parameter to e.g. GTK_DISPLAY_NOTE, which is
usually a call to gtk_widget_get_display.
Before this patch, gtk_widget_get_display was the slowest part of
gtk_widget_query_size_for_orientation.
We were leaking the GBytes for the image memory, which is a
noticeable memleak to anyone who's casually running a memory monitor.
Go KDE users!
Closes#1200
The min size on the oriented axis used to come from style props with
default values in the source file, used if the theme did not provide a
min size in CSS. When the style props were removed, so was any notion of
a minimal size for proressbars' main axis, meaning that now progressbars
without expand or any other source of min size were just tiny specks.
The right place to do that was always the theme, so in our themes now,
fix that by copying the old default values for the style properties; see:
https://gitlab.gnome.org/GNOME/gtk/issues/1191#note_259393https://gitlab.gnome.org/GNOME/gtk/blob/gtk-3-24/gtk/gtkprogressbar.c#L92
The result should be the same in that (A) the min size is now what it is
in GTK+ 3 & (B) an app/user can override the theme exactly the same way.

This commit includes the necessary updates to the X11, Wayland
and Broadway backends. Other backends have to be updated separately.
It looks like this got dropped during the move from autotools and never
restored. I can see why, since making it work wasn't a hugely fun task!
Notes on some less then obvious details:
* PlacesSidebar is private now and didn't seem to be to be particularly
easy to adapt to, so this moves to checking for it by name, not TYPE.
I couldn't find a (fast) better way; if you know how, please clean up
* added 2 casts to avoid warnings from the new type-propagating ref()
* GdkClipboard and GdkContentProvider need some properties dodged
* GtkToolItemGroup is gone
* fixed indentation and used TypeName:property-name syntax in a print()
Also update the cursor surfaces of every seat when an output changes
scale. This could for example happen when a monitor scale is changed via
Settings.
If we check it too early, we will not unset priv->draw_neeeded, which
will then cause queue_draw() calls to not have an effect later. And that
causes changes in opacity to not register.
Closes#1180
The comment above explains neatly why subclassing GtkButton for
GtkColorButton was a bad idea. Nowadays it's a GtkWidget subclass
containing a GtkButton so let's remove the special case here.
Binds this property to the button's label, allowing a model button to
have text with markup.
This will be convenient for buttons like 'Online Accounts <sup>↗</sup>'.
When deciding whether or not to emulate a press event, we're translating
the last event coordinates and mutating the given event structure
unconditionally.
We should modify the newly created GdkEvent copy, since it's what we're
going to use when emitting the press event.
This avoids mutating a constant GdkEvent and global state, and also
avoids a compiler warning.
The idea is that GTK+ 4 will be an epoch, API-wise.
Everything that was around for 4.0 has been there
since the beginning of the epoch and doesn't need
markers.
If the parent get_preedit_string implementation returns a nonnull
zero-length string, then we ignore it, which is almost fine. We have to
free it, though.
Fixes#1174
Expanders used to be 16px high. With the move from the gtk2 rendering
to gtk3 rendering they shrunk to 12px, making them hard to see, because
it's now the icon which is 16px high and the icon contains transparent
borders.
This makes the HighContrast theme use 24px icons instead, to restore
16px expanders. This may expander some containers a bit.
Closes#1046
GtkTextHandle was neglected by whoever removed the ::draw signal,
leaving it entirely broken. Update to using GtkGizmo so we can
implement snapshot of text handles.
Input has received a revamp too, handling is done through a
GtkGestureDrag and coordinate calculations simplified by storing
the delta to the hotspot on ::begin instead of ::update, as this
value is constant throughout the gesture. Widget state management
on crossing events happens implicitly, so no longer needs to be
done here.
Last but not least, CSS has also been updated so handles are
rendered at the correct size and proportion, and with the padding
that code expects of it.
Set up a gesture on the sidebar rows to detect pointer clicks on
it. The row DnD management has been moved to the row widget itself,
it makes more sense even if the drag is began from the sidebar widget.
We still need a drag gesture both on front (capture) and back (bubble)
to handle dragging from both the GtkWindow widget and chrome in the
headerbar. But we can do it through 2 drag gestures, instead of special
event handling code.
This has been broken since we switched key event delivery to follow
the same semantics than pointer/touch. There, GTK+ grabs will influence
the topmost widget during event delivery, rendering the toplevel
unable to handle key navigation. The toplevel must handle those key
events in an explicit manner then.
We don't render the keyboard focus rectangle yet, but I assume that's
something else.
Use an event controller on GtkFontChooserDialog, a nice side effect
is that we can use gtk_event_controller_key_forward() and
gtk_search_entry_set_key_capture_widget() instead of passing events
around for dialog search.
Instead of doing all handling manually in the ::event vfunc,
set up drag/multipress gestures on icon images, and implement
emission of ::icon-press/release and DnD there.
As a side effect, the GdkEvent field in ::icon-press/release
signals has been dropped. Callers that might be interested on it
may still use gtk_get_current_event*().
This isn't really necessary, if keyboard focus forcibly goes somewhere
else we will get ::grab-notify, which is sufficient to deactivate the
button again.
Selected rows in tree views in HighContrast have a background colour the
same or nearly as the normal text colour, so we cannot let entries in
such rows have transparent backgrounds, or the text inside the entry
becomes nearly or totally impossible to see.
Dodge this by giving entry.flat inside treeview and with :focus the
$base_color, which is different from the text & so lets that be seen.

This reverts commit 8e74eb382f.
This code is not necessary. It worked around a bug in graphene where
graphene was requiring stricter alignment than glib allocators could
guarantee.
The else case was wrongly resetting the accessible description on the
primary icon, which might not exist and can therefore cause a crash.
https://gitlab.gnome.org/GNOME/gtk/issues/1160
This functionality is similar to Linux's memfd. It creates anonymous shared memory without touching the filesystem, which allows it to work in Capsicum capability mode (sandbox).
The claimed status check should happen after ::end is emitted,
as the gesture may deny the sequence that much late. In this
case the event should keep propagating.
https://gitlab.gnome.org/GNOME/gtk/issues/1159Closes: #1159
We are poking again into the event propagation machinery, which
expects events in toplevel coordinates. Since we can't fetch the
original event back at this point, translate the coordinates
back to the toplevel so the emulated press ends up in the right
place.

* There's no GdkDragContext->dest_surface anymore.
Add dest_window field to GdkWin32DragContext,
and use that instead.
* Remove unused function prototypes
* Add more comments
* Rename variables and fields from 'window' to 'surface'
where appropriate
* Fix header indentation a bit
* Try to ensure that uninitialized/unknown handle variables
and fields are set to INVALID_HANDLE_VALUE instead of NULL,
as there may be cases where NULL is a valid handle value.
This might be foreign Windows and we don't want to create surfaces for
those.
Also, stop using GdkDragContext.dest_surface, that variable is meant to
go away.
In particular, this patch removes:
gdk_surface_get_events()
gdk_surface_set_events()
gdk_surface_get_device_events()
gdk_surface_set_device_events()
Event masks so far still exist for grabs.
GdkDragContext => GdkDrop
This is all in preparation of separation of the drag and drop.
Also, don't check for GDK_DRAG_PROTO_XDND anymore - it's the only
possible value for the protocol on the target side.
Use the new method of connecting to the xevent signal instead.
Also, don't consume the xevent, there might be other code listening for
it. And we don't use PropertyNotify in the generic code path anymore, so
it'll just be ignored there.
* Remove clipdrop->dnd_target_state, it's not used anymore
* Remove non-functioning _gdk_dropfiles_store(), store dropfiles
list in GdkWin32Drop instead
* Fix multiple comment typos
* Fix _gdk_win32_get_clipboard_format_name_as_interned_mimetype() to
leave names that look like mime/types alone
* Refactor _gdk_win32_add_w32format_to_pairs() to populate
GdkContentFormatsBuilder directly, instead of making a GList
* Rename context -> drag (still using GdkDragContext type,
but [almost?] all variables and comments say "drag" now)
* Rename GdkDropContext -> GdkDrop
* Rename some parameter names for clarity
* Rewrite local protocol to look more like OLE2 protocol
instead of mirroring the structure of the X11 API.
* Add handle_events field to GdkWin32DragContext,
to shut off event handling (temporary fix until GTK is patched up)
* Remove _gdk_win32_drag_context_find() - the drag object is stored
in GdkDrop instead. Use _gdk_win32_find_drag_for_dest_surface()
to get it initially.
* Remove target_ctx_for_window, droptarget context is stored
in the surface instead.
* Call gdk_drag_context_set_cursor() just like wayland backend does
(slightly broken for now)
* Clean up the action choosing code (filter source actions by using
keyboard state, pass that to GTK, get all actions supported by GTK in
response, match them up with filtered source actions, return the
result, falling back to COPY in case of multiple actions)
* Check drag_win32->protocol instead of the use_ole2_dnd variable where
possible
* Remove protocol checks from functions that are only used by the local
protocol
* Use event state to manufacture the keyboard state for WM_MOUSEMOVE
* Change function names printed by GDK_NOTE to name the actual
functions, not their theoretical generic GDK stack ancestors
* Consistently use drag_win32 and drop_win32 variables instead of a mix
of that and win32_drag/win32_drop
* Return FALSE from button handler to ensure that GTK gets the button
event to break implicit grab
* Emit leave event on failed idroptarget_drop() calls
Instead of looking at the list of contexts, just look at the current
drop context. There is only one, after all.
Then remove the is_source argument from gdk_drag_context_find().
The filters now return TRUE/FALSE and no longer a GdkFilterReturn. They
also don't conform to the GdkFilterFunc typedef anymore but instead take
the arguments that they need.
This is not needed because GTK must be run in the main thread these days,
which is the same one that runs the main loop. So when this function is
called, the main loop is awake.

This uses the new method without GDK_ACTION_ASK:
Either it is a single action (queryable via gdk_drag_action_is_unique())
or it is not and then the drop target has to make a decision
(potentially by asking someone).
The ultimate goal of this patch series is to split GdkDragContext into
GdkDrop + GdkDrag classes for the destination and source side of a dnd
operation.
The refactoring is meant to work something like this:
1. Introduce GdkDrop as a base class
2. Make all drop related code (like GdkEvent) use GdkDrop instead of
GdkDragContext. Move/duplicate APIs to allow that.
3. Port all drop contexts in the backends from GdkDragContext to GdkDrop
4. Delete all APIs in GdkDragContext that aren't needed anymore.
5. Make GdkDragContext no longer a GdkDrop subclass
6. Rename GdkDragContext to GdkDrag
In 01455399e8 ("gdk: do not deactivate surface on keyboard grabs"), we
made gdk avoid deactivating surfaces when another application takes a
keyboard grab, by using has_focus_window instead of has_focus. That however
broke activating surfaces when the gdk application acquired a grab itself,
in which case has_focus_window is false but has_focus is true.
We thus actually need to use both: surfaces should be activated either
because we have normal keyboard focus, or because we grabbed the keyboard.
This also renames HAS_FOCUS to APPEARS_FOCUSED to better reflect its
role.
Fixes#85
According to the old new thing[0], we should use the instance handle
of the GDK/GTK DLL when registering GDK-specific types in the system.
Using the instance handle for the whole application in these circumstances
is not an error, but can potentially clash with the types registered
by the application itself.
Also, extract window class icons from the GDK/GTK DLL, not from the
application executable.

The argument is eventually passed to g_conv(), so it should
be the charset, not the mime/type. Without this change the
contentype converter will fail to convert UTF-8 strings to, say,
CP-1251 later on.
Unconditionally putting 'gdkwayland_inc' in src_dir argument of gtkdoc
call tells gtkdoc-scan to scan source files in a non-existent build
directory, gdk/wayland. To avoid causing build failure when a specific

When a remote instance of a GTK application implementing the Startup
Notification protocol gets spawned it will pass the startup sequence
ID as "platform data" to the main instance. Thus, we need to make sure
that the startup sequence gets completed in that case, since the remote
instance won't do it by itself, since it won't map any top level window.
Checking for this "platform data" in the implementation of the after_emit()
virtual method in the primary instance should be a good place to do so, since
the existence of such data proves that a remote instance has been spawned.
https://gitlab.gnome.org/GNOME/gtk/issues/1084
The DESKTOP_STARTUP_ID gets cleared early after the process is spawned,
meaning that it's too late at add_platform_data() to pick it up and send
it over to the primary instance, as it will be always unset at that point.
To solve this, we use the new gdk_display_get_startup_notification_id()
method to pull the startup notification ID for the application, if present,
out of the display and pass it over to that primary instance.
https://gitlab.gnome.org/GNOME/gtk/issues/1084
Includes implementation for Wayland and X11, which are the only backends
implementing the Startup Notification Protocol, returns NULL otherwise.
https://gitlab.gnome.org/GNOME/gtk/issues/1084
Similar to what has been done recently for DESKTOP_AUTOSTART_ID [1],
we need to get rid of this call to g_unsetenv() in the displays'
backends for X11 and Wayland, so that it's guarantee to happen any
thread is created, while still being accessible when needed.
Let's stash the value of this environment variable when loading the
GDK library, and provide a private method so that it can be retrieved
from the displays' backend when implementing gdk_display_make_default().

check_dir_mtime() is called by ftw() and is given
the real stat struct, not its glib version (which may
or may not be the same as "struct stat").
This is irrelevant for MSVC (it has no ftw()) and
works correctly for MinGW-w64 (which declares stat
structures correctly). If mingw.org complains, add
a special ifdef for it later.
It's quite old, but mostly harmless (both "message == WM_KEYUP"
and "message = WM_KEYUP" evaluate to not-FALSE, and message
value is not used after that line).
Any data that is later fed to graphene must be
allocated with proper alignment, if graphene
uses SSE2 or GCC vector instructions.
This adds custom array code (a streamlined copy
of GArray with all unnecessary bells and whistles removed),
which is then used for the state_stack instead of GArray.
There's also a runtime check for the size of GtkSnapshotState
itself being a multiple of 16. If that is not so, any array
elements past the 0th element will lose alignment.
There are probably struct attributes that can
make GtkSnapshotState always have size that is a multiple
of 16, but we'll burn that bridge if we cross it.
The check survived from GTK2 when that function could still return
GdkPixmap and GdkFont objects and was accompanied by this comment:
/* We may receive events such as NoExpose/GraphicsExpose
* and ShmCompletion for pixmaps
*/
and gtk_image_set_can_shrink().
Images are meant to always be icon-sized, they can never shrink below
that.
And images are icons, so they are meant to be square. If they are
not, we pretned that's by accident and keep aspect ratio.
This commit introduces GtkPicture, which is supposed to complement
GtkImage.
GtkImage will be adapted to always display an icon, while
GtkPicture displays regular imagery.
Instead declare a priv local. We should do this even if we don't remove
the priv pointer from GtkWidget entirely, just to stay consistent with
new code we introduce.
The code is mostly stolen from graphene.
Allocators support any alignment, but their implementation
only calls system aligned allocator functions if malloc()
is not aligned to 16-byte boundaries. If it is aligned,
the implementation just calls malloc() regardless of which
alignment is requested by the caller.
This can be fixed by saving the result of meson malloc()
alignment check and adding a few conditions to the implementation,
but right now GSK and GTK only need 16-byte alignment either way.
* A bunch of new variables for config.h.meson
* A check for aligned allocation being necessary at all
(graphene must use GCC vector instructions or SSE2)
* A check for C malloc() being aligned at 16-byte boundaries
* A check for a few special aligned allocator functions being
present and not being built-ins (posix_memalign is a builtin
in GCC, even on platforms where there is no posix_memalign
system function)
* Added -mstackrealign flag on Windows, since otherwise
stack variables may become unaligned when the stack briefly
passes through OS code (such as in various callbacks and
handlers)
Otherwise, requesting a min size in em where the equivalent in px had a
fractional part would lead to the widget getting allocated 1 too few px.
You could see this in the CSS property vs. allocation in the Inspector.
Note that margin/border/padding are left alone: the rationale is that we
do as browsers do, and Benjamin said we already do that for those,
whereas his tests on min-(width|height) showed otherwise. My subsequent
analysis indicated it to be far less clear-cut than that, but he remains
unconvinced that we should ceil() all the things! So just do these ones.

This is the API used by GtkMenu to properly position menus on the screen
without requiring GTK to query the menu window's position or the work
area of where the window is positioned. It makes it possible to position
popup windows properly when using Wayland.
Make this API available to external users so custom popup windows can be
positioned properly as well.

Causing a grab in the handler for ::pressed by, e.g., popping up a
context menu will cause the gesture to be canceled and, subsequently,
::end and ::released to be fired, all while the button is still
physically pressed. That results in no event being available to the
::released handler and garbage coordinates, given that
gtk_gesture_get_point() returns FALSE.
Emitting ::released can be avoided by checking the return value
gtk_gesture_get_point().
Querying the event sequence of a gesture will always yield NULL for
non-touch events, but passing NULL in to calls to
gtk_gesture_get_last_event() is a perfectly valid use case.
That code branch is meant to check for key events, seems obvious we want
GDK_KEY_PRESS, not GDK_BUTTON_PRESS (which also broke the branch right
below).
Makes us all able to dismiss popovers again.
We can just as well use notify::has-focus for the purpose of
focus tracking, and we can at the same time avoid emitting the
deprecated AtkObject::focus-event signal.
A recent dependency change in MSYS2 made it pull in vulkan, which made
meson think it's available but it somehow links against the system vulkan dll
instead.
Disable vulkan for now.
:climb-rate is not about what you get when you single-click on a button,

Fix the description of @climb_rate to new(), and while here, mention the

The last round of patches to get the desired direction of value move in
response to scrolls/keypresses on scales had the inadvertent side effect
of giving the opposite direction on scrollbars. Seeing as gtkrange.c is
already a collection of hacks, add another so that fix only holds if the
instance is a GtkScale, since that is what those patches were aimed at.

We were mutating the list while iterating over it. This was not a
problem before since remove_controller just set the controller pointer
to NULL instead of actually removing it from the list of controllers.
We can avoid a signal connection per event controller (and the
EventControllerData struct) since every event controller knows the
widget it's attached to.
GtkTextView scrolls to the insertion point when the text
buffer signals a paste is done. This is wrong when there
are multiple views on the same buffer, and the paste
happened in another view.
To fix this, flip the handling of the scroll_after_paste
boolean to only be TRUE if we know that we want to scroll.
The gtk_app_chooser_dialog_set_heading() function do emit
notify::heading. Since the setter simply calls the function,
the setter itself shouldn't emit a notify signal by itself.
The bubble_timeout_id was reset only on some special case.
And so warnings were shown when the source is being tried
to be removed with the already removed id.
Fix this by unconditionally resetting the id on start of the function.
When an animated cursor was set and the previous cursor animation delay
happened to be the same, we wouldn't restart the animation timeout and
just return G_SOURCE_CONTINUE assuming the timer would continue. This
assumption is however only valid if the function was called from the
timeout, which is not the case.
Instead also arm the timer also if there is no previous timer active.
gdk_wayland_*_grab()/ungrab() would emit crossing events which translate
as focus_in/focus_out events for keyboard.
However, the ungrab() functions compare the native toplevel as this is
what gets the Wayland pointer enter/leave events with the grab surface,
so if the grab is issued on a child gdk surface, those won't match and
we would emit more focus_out events than focus_in.
This means that a widget such as spice-gtk which issues a keyboard grab
whenever the pointer enters the surface and releases the grab when it
leaves the surface would get uneven numbers of focus_in/focus_out
events.
Also, gdk_wayland_seat_ungrab() would not emit crossing events for
keyboard devices, whereas gdk_wayland_device_ungrab() does, which adds
even more potential discrepancies between focus_in/focus_out events.
To solve this problem, introduce two new helper functions which check
the relevant native surfaces to emit crossing events when needed that
get called evenly from both gdk_wayland_seat_grab()/ungrab() and gdk
_wayland_device_grab()/ungrab() APIs.

The last parameter of the signal callback from .ui
is the template's object from which the class is
derived.
And so, we already have access to the window object.
Let's just use it.
Our flatpak-builder manifests include building Graphene from Git; since
we're building the GTK demos, it's pointless to build the Graphene tests
as well. Disabling tests and benchmarks avoids pointless installations
inside the Flatpak build repo that will just be removed by the time we
bundle the demo.
1. Include the broadway renderer (so we can test it properly fails on
Wayland or X11)
2. List all potential renderers, print useful information when Vulkan
is not compiled in instea dof omitting it
3. Improve docs
Instead of tracking offers in GdkWaylandSelection objects, track the
pending offer in the GdkWaylandSeat and pass it to the GdkDragContext
once we get an enter event.
A container node inside another container node doesn't make a lot of
sense, we can instead just use the parent container node and add the
child container node's children to it directly.
The header linux/input.h used by GDK is specific to Linux. It is
possible to get a few Linux headers on FreeBSD by installing v4l_compat,
but it is usually better to use the one shipped with FreeBSD.
We prefer dev/evdev/input.h to linux/input.h here, so it will always use
dev/evdev/input.h on FreeBSD regardless of v4l_compat.

This commit adds support the stable version of the xdg-shell protocol.
Support for the last version of the unstable series is left intact, but
will not receive new features.
The stable version is prioritized above the older version.

When pressing e.g. a window manager shortcut, which acquires keyboard grab,
Xorg would send FocusOut NotifyGrab then FocusIn NotifyUngrab. Currently
gdk would then deactivate the current surface, which makes accessibility
screen readers think that we have switched to a non-accessible application
and came back again, and thus reannounce the application frame etc. which we
don't want when e.g. just raising volume.
And actually, receiving FocusOut NotifyGrab does not mean losing the
X focus, it only means an application aqcuired a grab, i.e. it is
temporarily stealing keyboard events. On Wayland, this isn't even
notified actually.
This commit makes gdk only deactivate surfaces when there was an actual
focus switch to another window, as determined by has_focus_window (instead
of just has_focus), which happens either normally through FocusOut with
NotifyNormal, or during grabs through FocusOut with NotifyWhileGrabbed.
Fixes#85
gdk_win32_keymap_check_compose() shouldn't be called for
non-W32 displays (i.e. when using broadway or other backends
that could be made to run on Windows).
We no longer set the widget on construction, but instead require an
explicit call to gtk_widget_add_controller().
This way, the reference handling becomes explicit and bindable.
Because gtk_widget_add_controller() is (transfer: full), we don't
even need to unref the controller after adding it.
And we don't need to keep track of it, because controllers get cleaned
up by GtkWidget.
This is the first step towards refactoring how widgets deal with event
controllers.
In the future, the widget will treat controllers the same way it treats
child widgets:
1. The controllers will be created without a widget.
2. There will be gtk_widget_add/remove_controller() functions to add
or remove controllers.
3. The widget will hold a reference to all its controllers.
This way we will ultimately be able to automate controllers with ui
files.
gtk_get_current_event() returns a new reference to the event, it should
be freed across various return branches to avoid the event leak, or we
just fetch the little stuff we're interested in.
Now that all Cairo contexts are ported to managing cairo surfaces
themselves, the old fallback code that didi the managing is no longer
needed.
Also clarify the behavior of gdk_cairo_context_cairo_create() wrt the
vfunc by doing the early exit and the clipping outside of it.
* Remove DC refcounting (we trust GDK to always do
begin_frame/end_frame calls in pairs)
* Now that there's no GDK-provided double-buffer up the stack,
double-buffering is implemented here
(though it's disabled by default - in my tests it didn't provide
any visual improvements, but did decrease performance).
* For some reason delaying window resizes until the point where
we need to blit the double-buffer into the window leads
to visual glitches, so doulbe-buffered windows are resized
in begin_frame, same as non-double-buffered ones.
* New code to clear the paint region, for all drawing modes.
Hopefully, it isn't duplicated anywhere up the stack.
* GL has its own context now, so remove any GL-related comments.
* Layered windows are still used (because cairo actually works
better with them)
* A bit more code re-use for layered windows
* Some functions that were local to gdksurface-win32.c are made
usable for the whole backend
* Drag-indicator drawing is temporarily commented out to match
a similar change in X11 backend
We used to pass 2 regions to GdkDrawCotnext.end_frame() but code was
confusing what they meant. So we now don't do that anymore and only pass
the region that matters: The frame region.
This makes the previous gdk_draw_context_is_drawing() function public
under a new name.
I decided against the old name because we use the term "frame" for a
drawing operation, so I wanted to have this boolean flag reuse the term.
As they require a draw context and the draw context is already bound to
the surface, it makes much more sense and reduces abiguity by moving
these APIs to the draw context.
As a side effect, we simplify GdkSurface APIs to a point where
GdkSurface now does not concern itself with drawing anymore at all,
apart from being the object that creates draw contexts.
Previously, we got the damage, then computed the changed area, then
started a frame with that changed area.
But starting a frame computes the damage for us.
So now we start a frame, then get the damage area from that, then
compute the change area.
Also, split it into its own file - which was the original reason for
looking at this code, the rewrite was an unintentional side effect.
This changes the context to create surfaces on demand.
So whenever the compositor holds onto a surface while GDK wants to
render, it just creates a new surface. If the compositor releases
surfaces, we will retain one for the next frame to be rendered, but free
all extra ones.
This way, we should get to a stage where we have exactly as many
surfaces as needed and never allocate/free any.
Also, don't implement SurfaceClass.ref_cairo_surface() anymore. This
means calls to it will crash now. But as they only happen in the generic
GdkCairoContext implementation, we shouldn't be affected by that.
Plus, once all backends have been ported, that call is going away
anyway.
And make the GdkCairoContext as abstract.
The idea of this and thje following commits is to get rid of all
Cairo code in gdksurface.c (and $backend/gdksurface-$backend.c)
by moving that code into the Cairo context files.
In particular, the GdkSurfaceClass.begin_frame/end_frame()
functions (which are currently exclusively used by the Cairo code
should end up being moved to GdkDrawContextClass.begin/end_frame().
This has multiple benefits:
1. It unifies code between the different drawing contexts.
GL lives in GLContext, Vulkan in VulkanContext and Cairo in
CairoContext. In turn, this makes it way easier to reason about
what's going on in surface-specific code. Currently pretty much
all backends do things wrong when they want to sync to drawing
or to the frame clock.
2. It makes the API of GdkSurface smaller. No drawing code (apart
from creating the contexts) needs to remain.
3. It confines Cairo to the Drawcontext, thereby making it way
more obvious when backends are still using it in situations
where it may now conflict with OpenGL (like when doing the dnd
failed animation or in the APIs that I'm removing in this
branch).
4. We have 2 very different types of Cairo contexts: The X/win32
model, where we have a natively supported Cairo backend but do
double buffering ourselves and use similar surfaces and the
Wayland/Broadway model where we use image surfaces without any
Cairo backend support and have to submit the buffers manually.
By not sharing code between those 2 versions, we can make the
actual code way smaller. We also get around the need to create
1x1 image surfaces in the Wayland backend where we pretend
there's a native Cairo surface.
This does nothing but disallow passing NULL to gdk_surface_begin_paint()
and instead require this context.
The ultimate goal is to split out Cairo drawing into its own source file
so it doesn't clutter up the generic rendering path.
1. Remove set_icons property
2. Make it a GtkWidget subclass
3. Add gtk_fishbowl_set_creation_func()
4. Make the widgetbowl use the new benchmarking infrastructure of the
fishbowl
And of course, gsk_render_node_get_name() is gone, too.
The replacement is of course debug nodes.
As a side effect, GskRenderNode is now *really* immutable.
The shortcuts inhibitors hash table is created when we create a
GdkWaylandWindow implementation for a GdkWindow, and it's destroyed once
we finalize the instance. The fake "root" window we create for the
Wayland display does not have a backing native window, so the shortcuts
inhibitors hash table is set to NULL; this causes a critical error
message when calling g_hash_table_destroy() on it. The finalization of
the root window happens when we close a display connection.
We should use g_clear_pointer(), instead, as it's NULL safe.
Without this change, the displayclose test fails, as all warnings are
considered fatal.
Instead of hard-coding linker flags for a specific operating system and
a specific compiler, we can should cc.links to test them, so they can be
used on more operating systems and compilers.
All of the four platform-dependent backends are enabled by default. It
is usually a good default because it requires users to explicitly choose
backends they want to use. Rules in meson.build also automatically
disable unavailable backends for macOS, Windows, Linux, so users on
these 3 major platforms don't have to manually disable things when
running meson commands.
However, meson.build doesn't do the same thing for other Unix-like
systems, which is acceptable but not ideal. To make it easier to build
GTK+ on these systems, the Linux case, which enables X11 and Wayland and
disables Win32 and Quartz, is made the default for all operating systems
that are not Windows or macOS.
This commit also changes most 'host_machine.system()' calls to os_*
variables, which are easier to read and less likely to be used wrongly.

.linked assumes the container is a GtkBox, which is documented as never
flipping children in RTL, so :first-child is always the left child, etc.
GtkBox does that by reordering its CSS nodes when the direction changes.
But most widgets don’t do that, so :first|last-child are 1st/last ADDED
and swap sides in RTL. GtkPathBar is so, and ignoring that in our themes
meant that in RTL, its left/right buttons got each other’s borders. Yuk!
This patch adds the groundwork for supporting widgets like that, via the
%linked_flippable placeholder, and applies that to override buttons in
filechooser .path-bar.linked > button
so that the correct borders get applied to those buttons when using RTL.
Note that I select only PathBars within a FileChooser because we also
have NautilusPathBar, which also uses widget.path-bar – but *does* flip
its nodes for RTL already, so letting that get affected broke it again!

Well, they don't require a redraw of the widget, because the widget
itself didn't change.
They require a redraw of the parent, because that now displays the
widget in a different position.
And this means we can keep the cache of the widget's render node.
My fishbowl numbers are through the roof^W water surface. Vulkan gets
4000 now.
Due to the few type checks in gtk_widget_get_display(), it was the
slowest part of a call to gtk_widget_query_size_for_orientation if the
in case of a cache hit.
We pulled out the bounds calculation for performance reasons, but the
caller can't know how to properly compute them. Inside gtk+, we can do
that but it's not good enough for public API.
The GVariant we are getting here might not be coming
from GTK+, but rather from some other source. Best to
be forgiving and deal with missing data without crashing.
This was causing the GTK+ portal backends to crash on
print requests from Qt.
It might happen otherwise that a change is recorded in between the
widget dispose and finalization, causing a crash when setting
the visible name for the GtkStack (as that will be NULL at that point)
This will be used in subsequent commits to fix the sign by which the
value is changed in response to directional scroll or keypress events.
The idea is: you have a movement to make – in the form of a delta that
follows widget directions, i.e. −1 means left or up, +1 means right or
down – and you want to know whether that delta needs to be inverted in
order to produce the intuitively expected directional change of :value.
The existing should_invert() is not sufficient: it just determines
whether to invert visually, but we need more nuance than that for input.
To answer that – while not doubling up the work for scrolls and keys – I
add a helper should_invert_move(), which considers other relevant state:
• A parallel movement on priv->orientation should just use the existing
should_invert(), which already worked OK for this case (not others).
• Movements on the other orientation now depend on priv->orientation:
◦ For a horizontal Range, always invert, so up (i.e. −ve in terms of
widget coords) always means increase value & vice-versa. This was
done in get_wheel_delta(), but move it here for use with keys too.
◦ For a vertical Range, ignore :invert as it’s only relevant to the
parallel orientation. Do not care about text direction here either
as RTL locales do not invert number lines, Cartesian plots, etc.
This returns TRUE if the delta should be inverted before applying to the
value, and we can now use this function in both scroll and key handlers.

If widgets want to clip things, they now need to do it themselves.
By not taking care of clip, we avoid the need to track clip. And by not
tracking clip, we can avoid all unnecessary cache invalidations that we
were doing for render nodes whenever the clip changed.
And when you are scrolling, the clip changes *a lot*.
priv->button is a guint, but we assigned it to a local gint.

When filing a new merge request it's often hard to know who to ask for a
review; using the Git log doesn't always help — the person that touched
a file last may just be fixing the build or a compiler warning.
The `CODE-OWNERS` file format is something that GitHub uses in order to
pre-fill the list of reviewers:
https://help.github.com/articles/about-codeowners/
Ideally, in the future, we'll be able to use this file with a bot like
homu to automatically go through newly filed merge requests and
automatically ask the relevant people for reviews, instead of doing this
manually.
Keep in sync with the current tree.
The changes are mostly caused by updates in the internal hierarchy of
composite widgets, and the fact that the order in which the widget tree
is traversed is not exactly stable.
Instead of having a single massive test running through the a11y
directory, we can split off each individual file into its own unit.
Having individual units has several advantages:
- units are executed in parallel
- it's easier to identify the failing units
- logs for failed units are easier to read
We can't freeze the frame clock on commit, but only after-paint,
otherwise the frameclock will resume in the paint stage.
So freeze the frame clock at the end of the frame if we are waiting for
a frame callback.
Note; The diff is only lage because of indentation changes due to
avoiding early returns in favor of a branch.
GTK does use libintl directly (in gtkmain.c, for example) and thus
needs to be linked to it (if found and/or needed).
Previously we most likely were getting libintl from glib, but
that stopped for some reason. Either way, explicit linking is
the right thing to do here.
Instead of going through an ancillary script to strip away the
`WL_EXPORT` annotation from the generated code, we should bump up the
required version of Wayland, and use the `private-code` argument for
wayland-scanner, which does the right thing for us.
There where some problems (??) with ccache not detecting changes during meson
checks. Setting CCACHE_DISABLE during the meson execution makes ccache not use
the cache and pass things directly to the compiler.
Instead of connecting to / disconnecting from the frame clock, do it
inside the vfuncs next to changing the priv->realized boolean.
This removes a race between those 2 cases that could cause child
widgets' unrealize handlers to reconnect this widget to the frame clock
because it was still marked as realize when the widget had already
disconnected from the frame clock.
Fixes#168
But in turn, also allow it to work on widgets with their own surface.
This way, we can chain up from everywhere and won't have to export
gtk_widget_set_realized().
When using strncpy() with a buffer we need to account for the
terminating NUL character. GCC 8 started warning when using PPD_MAX_NAME
as the buffer length for strncpy() because the buffer we're copying into
has the same length — which means that the terminating NUL may be
skipped if the source string has a length of PPD_MAX_NAME.
The appropriate way to handle the case where we're copying a source with
a length bigger than of PPD_MAX_NAME is, as reported in the strncpy()
documentation, to copy `PPD_MAX_NAME - 1` bytes, and explicitly NUL
terminate the destination buffer. This has the additional benefit of
avoiding the compiler warning.
* Previous commit had misleading info. The code was
added to begin_paint() instead of end_paint(). Though
that did not affect its performance in any visible way.
* Company advised to move the code to an "after_paint" signal
handler, so that it works on all renderers, not just Cairo.
This change caused high fluctuation in FPS values in fishbowl
when it is put in a situation where it cannot achieve 60fps
(such as using Cairo renderer at ultra-high resolution).
This seems to be deliberate and not a bug.
There is no easily apparent way of being notified when frame updates
happene exactly, so we just query frame info at the end of each paint.
If we query too often (faster than DWM refresh rate), we just get
the same values twice in a row, but that is, hopefully, highly unlikely.
Now that queue_draw() isn't restricted to clip anymore, we don't need to
care about clip in the CSS engine either.
We do keep GTK_CSS_AFFECTS_CLIP around though because GtkWindow does
care for the window's size.
When asked for a nonexistent (positive) monitor number,
gdk_x11_display_get_monitor would (at best) return an uninitialized pointer,
instead of returning NULL.
That way, we can store the right region there: The actual painted area
instead of the exposed area (which is way too small).
Also, the GL context is the only user of this data, so storing it there
seems way smarter.
Even widgets with an empty allocation may still want to draw stuff.
Examples include shadows or child widgets with negative margins.
Fixes GtkEntry's progressbar not showing up anymore.
Deferring a bit further making those a standalone controller, make
binding activation happen on run_controllers(), so it happens by
default on widgets (unless the key event was consumed earlier)
without the need of a legacy event controller.
Non gesture controllers have no means to collaborate with other
controllers, thus should be considered standalone entities. It makes
no sense to propagate any further if scroll/key controllers handled
the event.
Use a key controller instead. Note that this currently
breaks the handling of Enter, since we activate key bindings
twice, causing us to switch to the label and back.
This is a GtkGesture done to deal with stylus events from drawing tablets.
Those have a special number of characteristics that extend a regular
pointer, so it makes sense to wrap that.
This may result on the later emission of crossing events, with one of the
sides being already unmapped/unrealized. The widget being unmapped will
result on repick and emission of a set of crossing events anyway.
This event controller is meant to replace usage from key-press/release-event
handlers all through. Optionally it can be set a GtkIMContext, so interaction
is carried by the controller.

This patch fixes things by moving step 5 to before step 2.
1b9aa1b708 ('a11y: drop the focus tracker') removed a bit too much. We

emit anyway.
Fixes#127
Overlays are drawings that get rendered on top of the inspected window.
The only overlay in existence so far is the highlight overlay, which is
used to highlight widgets and replaces the "draw" signal handler used
previously.
Instead of just notifying the inspector of what is going to be rendered,
allow the inspector to modify it.
This way, the inspector can overlay information it deems relevant over
the render node while still having access to what the actual widget
(without the inspector) would paint.
If you want to draw a widget to cairo today, you create a widget
paintable, snapshot it to a render node and then draw the render node to
cairo.
And yes, this is that complicated on purpose. Don't draw widgets to
Cairo.
This allows being more specific about the size.
It's useful in particular when the resulting render nodes might be
too small for the size, not only when they are too large. For the
latter case, using a clip node would be enough.
It also requires adding a clip node when rendering the resulting
paintable, but that should be optimized out by GtkSnapshot when not
necessary.
This is actually not just a mechnaism to protect against too many
signals, but it's also a method to getting those signals at the wrong
time.
For every size/content change, a widget needs to invalidate twice:
Once when it queues a resize/redraw (going valid => invalid) and once
when the new size/content is actually assigned (going invalid => valid).
However, one of those invalidations might be inconvenient for the
listener. GtkImage for example does not like receiving
invalidate-contents signals when new contents are assigned, but is fine
with them when the old ones go invalid. And it will not try to draw the
paintable in between anyway.
So by bypassing the 2nd emission if nothing was changed, we can make
GtkImage happy.
This error message is printed into the journal if a GTK app can't
connect to eithre Wayland or X11. Make it at least mention who is not
capable of connecting to a server.
Unrelated, we might want to improve our error reporting when a GTK app
can't start, so that debugging issues with system startup / login get
easier to resolve.
When the clip changes that is passed to a snapshot function, we need to
create eventual cached render nodes because they might not have drawn
their whole area before.
Fixes issues with redrawing when scrolling.
When the max cost for finding a path gets to high, the diff can now be
aborted.
Because render nodes have a fallback method (by just marking the whole
bounds of the nodes as different), we use this to improve performance
of diffs.
This brings fishbowl (which is basically a container node with N images
that change every frame) back to close to previous performance.
Now that we have the full render nodes available, there is not much
benefit in fine-grained control over multiple rectangles.
In particular, it's causing pain with complex regions.
There might be a benefit in clipping to the region's rectangles in cases
like widget-factory where the whole diff is made up of the 2 rectangles
of spinner and the pulsing progress bar, but it needs a good heuristic
for where this is useful.
Instead of calling gdk_surface_invalidate_region(), just
gdk_surface_queue_expose() and rely on the renderer computing the diff
from the previous rendering.
... and diff the previous node with the current one to determine the
clip region.
This doubles the work necessary to track clip regions, but the following
commits will clean that up.
It doesn't need to be exported anymore.
As a side effect, the inspector no longer has any information about the
render region, so remove the code that was taking care of that.
Now that we don't clip the created render nodes anymore, we don't have
to compute the clip region beforehand.
So snapshot the render nodes before initializing the renderer.
This includes a copy of the diff(1) algorithm used by git diff by Davide
Libenzi.
It's used for the common case ofcontainer nodes having only very few
changes for the few nodes of child widgets that changed (like a button
lighting up when hilighted or a spinning spinner).
This requires a bunch of refactorings:
1. Don't pass the current clip region to gtk_widget_snapshot()
so we don't create full widget contents
3. Have a widget->priv->draw_needed that we invalidate on every
queue_draw() call and set on every snapshot()
2. In queue_draw(), walk the widget chain to invalidate the
render nodes of all parents
... and gsk_render_node_can_diff(). Those are vfuncs to compute a region
containing all the pixels that differ between the two nodes.
This is just the plumbing that chains into node classes. No node
implements it yet.
delete_range_cb is set to be called before the text suppression done by
the gtktextlayout (otherwise it does not work properly). But at that
point the cursor position is not yet up to date. We thus need to move
the accessibility cursor notification to after the actual text
suppression, by using another callback.
This fixes cursor position in brltty screen reading.
(cherry picked from commit fa6994d033)
The second parameter of the text-changed::delete event is to be the length,
not the end position. This fixes spurious text removals in brltty
screen reading.
(cherry picked from commit 209f908a03)
Like other widgets, this returns a floating reference, so
(transfer full) is wrong. Just omit the annotation as others do,
thus implying (transfer none).

langinfo.h and dirent.h, since they seem to be unused.

The demos are now built as GUI programs, which will require the presence
of WinMain() on Visual Studio builds, unless we specify the entry point.
Pass the /entry:mainCRTStartup linker flag on Visual Studio builds for
the demo programs so that they can link properly.

For some font features, we can figure out affected
glyphs, and show before/after. For some others, we
hardcode typical sequences.
Still to do: figure out how to find ligatures and
show them.
We now properly use GdkFrameTimings and can therefor check for dropping
even a single frame in the history (of 16 frames or 1/4 of a second).
Once that happens, we immediately stop adding new items to the bowl.
A side effect is that the number of icons is now a *lot* smaller.
This ensures that the frame clock gets updated with correct presentation
times even if nothing was drawn.
This is necessary for benchmarking but would also be relevant for videos
that want to sync to the frame clock but draw frames a lot less.
This commit ensures that each GdkSurface impl remembers the
cursor that GDK sets for it, and that this cursor is set
each time WM_SETCURSOR is called for that sufrace's HWND.
This is needed because W32, unlike X, has no per-window cursors -
the cursor on W32 is a global resource, and we need to keep track
of which cursor should be set when pointer is over which surface
ourselves (WM_SETCURSOR exists exactly for this reason).
This commit also makes GDK remember the surface that has an implicit
grab (since implicit grabs are gone from the upper levels of the toolkit),
and ensures that crossing events are correctly synthesized and the grab
is broken when surface focus changes. This fixes a bug where opening
a new window (by clicking something in some other, pre-existing window)
will make that new window not get any mouse input due to the fact
that the mouse-button-down event from that click caused an implicit
grab on the pre-existing window, and that grab was not released afterward.
Instead of now-unused GdkWin32Cursor class (a subclass of GdkCursor),
add a stand-alone GdkWin32HCursor class that is a wrapper around
HCURSOR handle.
On creation it's given a display instance, a HCURSOR handle and a boolean
that indicates whether the HCURSOR handle can or cannot be destroyed
(this depends on how the handle was obtained).
That information is stored in a hash table inside the GdkWin32Display
singleton, each entry of that table has reference count.
When the GdkWin32HCursor object is finalized, it reduces the reference
count on the table entry in the GdkWin32Display. When it's created,
it either adds such an entry or refs an existing one.
This way two pieces of code (or the same piece of code called
multiple times) that independently obtain the same HCURSOR from the OS
will get to different GdkWin32HCursor instances, but GdkWin32Display
will know that both use the same handle.
Once the reference count reaches 0 on the table entry, it is freed
and the handle (if destroyable) is put on the destruction list,
and an idle destruction function is queued.
If the same handle is once again registered for use before the
idle destructior is invoked (this happens, for example, when
an old cursor is destroyed and then replaced with a new one),
the handle gets removed from the destruction list.
The destructor just calls DestroyCursor() on each handle, calling
SetCursor(NULL) before doing that when the handle is in use.
This ensures that SetCursor(NULL) (which will cause cursor to disappear,
which is bad by itself, and which will also cause flickering if the
cursor is set to a non-NULL again shortly afterward)
is almost never called, unless GTK messes up and keeps using a cursor
beyond its lifetime.
This scheme also ensures that non-destructable cursors are not destroyed.
It's also possible to call _gdk_win32_display_hcursor_ref()
and _gdk_win32_display_hcursor_unref() manually instead of creating
GdkWin32HCursor objects, but that is not recommended.
If GtkExpander:sensitive was FALSE, the arrow still got the normal fg
colour, which made it look clickable, in contrast to the adjacent label.
Fix this by adding selectors to catch the applicable :disabled states.
Note: Needing these may indicate an oops in generic styles elsewhere,
but I couldn’t see any, so let’s just get it looking right for now.

Add a new W32 backend-specific message filtering mechanism.
Works roughly the same way old event filtering did, but without
events (events are GDK/X11 concept that never really made sense
on W32), so there's no functionality for 'altering' events being
emitted. If an event needs to be emitted in response to a message
do it yourself.
Implemented like this, it should give better performance than
if we were to use GLib signals for this, since W32 sends a LOT
of messages (unlike X11, which doesn't send events as often)
all the time, and invoking the signal machinery on *each* message
would probably be bad.

Rename GdkWin32Selection to GdkWin32Clipdrop, since GdkSelection
is mostly gone, and the word "selection" does not reflect the
functionality of this object too well.
Clipboard is now handled by a separate thread, most of the code for
it now lives in gdkclipdrop-win32.c, gdkclipboard-win32.c just uses
clipdrop as a backend.
The DnD source part is also put into a thread.
The DnD target part does not spin the main loop, it just
emits a GDK event and returns a default value if it doesn't get a reply
by the time the event is processed.
Both clipboard and DnD use a new GOutputStream subclass to get data
from GTK and put it into a HGLOBAL.
GdkWin32DragContext is split into GdkWin32DragContext and GdkWin32DropContext,
anticipating a similar change that slated to happen to GdkDragContext.
OLE2 DnD protocol is now used by default, set GDK_WIN32_OLE2_DND envvar to 0
to make GDK use the old LOCAL and DROPFILES protocols.
