We need to disconnect the frame clock when we unrealize (at which
point the old clock is still alive) not in destroy(). Since there
is no common unrealize for containers, trigger this from GtkWidget.
A switch of device may be significant for an application, so don't
compress motion events if they are for different devices. This simple
handling isn't sufficient if we have competing event streams from
two different pointer events, but we don't expect this case to be
common.
* remove gdk_frame_clock_get_frame_time_val(); a convenience
function that would rarely be used.
* remove gdk_frame_clock_get_requested() and
::frame-requested signal; while we might want to eventually
be able to track the requested phases for a clock, we don't
have a current use case.
* Make gdk_frame_clock_freeze/thaw() private: they are only
used within GTK+ and have complex semantics.
* Remove gdk_frame_clock_get_last_complete(). Another convenience
function that I don't have a current use case for.
* Rename:
gdk_frame_clock_get_start() => gdk_frame_clock_get_history_start()
gdk_frame_clocK_get_current_frame_timings() => gdk_frame_clock_get_timings()
Since we're not exporting the ability to create your own frame
clock for now, remove the setters for GdkFrameTimings fields.
Also remove all setters and getters for fields that are more
about implementation than about quantities that are meaningful
to the applcation and just access the fields directly within
GDK.
Now that GdkFrameClock is a class, not interface, there's no real advantage
to splitting the frame history into an aggregate object, so directly
merge it into GdkFrameClock.
It's unlikely that anyone will want to have, say, a GtkWidget that
also acts as a GdkFrameClock, so an abstract base class is as
flexible as making GdkFrameClock an interface, but has advantages:
- If we decide to never make implementing your own frame clock
possible, we can remove the virtualization.
- We can put functionality like history into the base class.
- Avoids the oddity of a interface without a public interface
VTable, which may cause problems for language bindings.
Instead of making the frame clock a settable property of a window, make
toplevel windows inherently have a frame clock when created (getting
rid of the default frame clock.) We need to create or destroy frame
clocks when reparenting a window to be a toplevel, or to not be a
toplevel, but otherwise the frame clock for a window is immutable.
Add a very simple GtkWidget function for an "tick" callback, which
is connected to the ::update signal of GdkFrameClock.
Remove:
- GtkTimeline. The consensus is that it is too complex.
- GdkPaintClockTarget. In the rare cases where tick callbacks
aren't sufficient, it's possible to track the
paint clock with ::realize/::unrealize/::hierarchy-changed.
GtkTimeline is kept using ::update directly to allow using a GtkTimeline
with a paint clock but no widget.
If we get a focus event for a X window we don't recognize, just
ignore it and avoid a g-critical when
_gdk_device_manager_core_handle_focus() is called with a NULL window.
Deprecate gdk_window_enable_synchronized_configure() and
gdk_window_configure_done() and make them no-ops. Implement the
handling of _NET_WM_SYNC_REQUEST in terms of the frame cycle -
we know that all processing will be finished in the next frame
cycle after the ConfigureNotify is received.
The first version of the video-timer simply played back the video
according to the wall clock, and showed each frame at the neareste
presentatin time. But an alternative strategy for playing back
video is that if the frame-rate is an integer-divisor of the
display refresh rate, or very close to that, is to change the playback
speed to complete avoid frame drops and changes in latency.
(This would require resampling audio if present.)
Demonstrate this technique by adding a --pll option to the
video-timer demo.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
Add a test case that simulates the timing operaton that goes on
when showing a constant frame rate stream like a video - each
frame is shown at the VBlank interval that is closest to when it
would ideally be timed.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
For an operation like synchronizing audio to video playback, we need to
be able to predict the time that a frame will be presented. The details
of this depend on the windowing system, so make the backend predict
a presentation time for ::begin-frame and set it on the GdkFrameTimings.
The timing algorithm of GdkFrameClockIdle is adjusted to give predictable
presentation times for frames that are not throttled by the windowing
system.
Helper functions:
gdk_frame_clock_get_current_frame_timings()
gdk_frame_clock_get_refresh_info()
are added for operations that would otherwise be needed multiple times
in different locations.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
Show the average and standard deviation of the latency in addition to
the frame rate. Add options to print the output in machine-readable form,
and to control the frequency and total number of statistics that will be
output.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
We want the compositor to do different things for frames where
"slept before" is TRUE. Communicate to the compositor that
frame is a no-delay frame (slept_before=FALSE) by ending the frame
by increasing the counter value by 1, and that the frame is a
normal frame (slept_before=TRUE) by increasing the counter value
by 3.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
Add functions that tell us whether the main loop slept before we drew
a frame. Blocking with the frame clock frozen doesn't count as sleeping.
We'll use this to advertise to the compositor whether we
are drawing as fast as possible (and it should do the same) or timing
frames carefully (and it should do the same.)
https://bugzilla.gnome.org/show_bug.cgi?id=685460
Don't start the idle if we're in the middle of painting a frame -
this will prevent us from getting the timing right when starting
the idle after the frame.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
In order to be able to track statistics about how well we are drawing,
and in order to be able to do sophisticated things with frame timing
like predicting per-frame latencies and synchronizing audio with video,
we need to be able to track exactly when previous frames were drawn
to the screen.
Information about each frame is stored in a new GdkFrameTimings object.
A new GdkFrameHistory object is added which keeps a queue of recent
GdkFrameTimings (this is added to avoid further complicating the
implementation of GdkFrameClock.)
https://bugzilla.gnome.org/show_bug.cgi?id=685460
Instead of communicating the start of a frame to the window manager
as soon as we begin a frame, start a frame only when we know we've
actually created damage to the contents of a window.
(This uses cairo_set_mime_data() as a notification mechanism - a
clever suggestion from Uli Schlachter.)
The advantage of this is that we aren't forcing the compositor to
do a frame cycle and send _NET_WM_FRAME_DRAWN - depending on how the
compositor is structured that might either cause it to do extra
work or it might send _NET_WM_FRAME_DRAWN early and upset frame
timing.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
Since events can be paused independently for each window during processing,
make _gdk_display_pause_events() count how many times it is called
and only unpause when unpause_events() is called the same number of
times.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
Unqueuing events from the windowing system when paused could result
in weird reordering if event filters resulted in application-visible
behavior. Since we now resume events when the frame clock is frozen,
we now no longer count on low-level event handling running while
event handling is paused.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
Keeping events paused after the end of a frame put us in a
weird state where we had to process and queue events - so that
we would get the message from the compositor - but not deliver
them. Instead resume events before ending the frame.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
When we have pending motion events, instead of delivering them
directly, request the new FLUSH_EVENTS phase of the frame clock.
This allows us to compress repeated motion events sent to the
same window.
In the FLUSH_EVENTS phase, which occur at priority GDK_PRIORITY_EVENTS + 1,
we deliver any pending motion events then turn off event delivery
until the end of the next frame. Turning off event delivery means
that we'll reliably paint the compressed motion events even if more
have arrived.
Add a motion-compression test case which demonstrates behavior when
an application takes too long handle motion events. It is unusable
without this patch but behaves fine with the patch.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
Add a test of a window with an animated size and contents. The
test accepts load factor command line argument to see how things
work as the drawing of the content requires more GPU resources.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
When we have a looping animation for something like an angle,
we need to make sure that the distance we go past 1.0 becomes
the starting distance for the next frame. This prevents a
stutter at the loop position.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
Use GdkFrameClock for the timing of GtkTimeline. This require the
user to provide either a GtkWidget or a GdkFrameClock when creating
the timeline. The default constructor now takes a GtkWidget. If you
want to create a GdkFrameClock without a widget, you need to use
g_object_new() and pass in a GdkFrameClock and GdkScreen.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
The frames-per-second for an animation should be controlled by how
fast we can process frames and the the frame-rate of the display; it's not
a meaningful app-settable property.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
Add back the GtkTimeline code that previously made private and
then removed. It will be hooked up to GdkFrameClock. This commit
purely adds the old code back.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
Switch GtkStyleContext to using GdkFrameClock. To do this, add a new
UPDATE phase to GdkFrameClock.
Add a GdkFrameClockTarget interface with a single set_clock() method,
and use this to deal with the fact that GtkWidget only has a frame
clock when realized.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
If the backend is throttling paints, then the frame clock will be
frozen at the end of the frame. If not, then we need to add throttling,
so wait until 16ms after the start of the frame before beginning the
next frame.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
By starting with an odd frame counter value, we make the mapping
and initial paint of the window an atomic operation, avoiding
any visual artifacts from an unpainted window.
Possible improvement: start the frame when doing gdk_window_show(),
so that the same improvement occurs for windows that were previously
shown and are being mapped again.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
When a window is unmapped, freeze its frame clock. This avoids doing
unnecessary work, but also means that we won't block waiting for
_NET_WM_FRAME_DRAWN messages that will never be received since the
frame ended while the window was withdrawn.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
As part of the extended _NET_WM_SYNC_REQUEST_COUNTER protocol,
we get a _NET_WM_FRAME_DRAWN message for each frame we draw. Use this
to synchronize the updates we are doing with the compositing manager's
drawing, and ultimately with with display refresh.
We now set the sync request counters on all windows, including
override-redirect windows, since it is also useful to do synchronized,
atomic updates for such windows.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
By exporting two XSync counters on a toplevel window, we subscribe
to an extended form of the _NET_WM_SYNC_REQUEST_COUNTER protocol,
where the window manager can initiate an atomic frame, as previously,
but the application can also do so by incrementing the new counter to
an odd value, and then to an even value to finish the frame.
See:
https://mail.gnome.org/archives/wm-spec-list/2011-October/msg00006.html
The support for 64-bit integers that GLib requires is used to
simplify the logic.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
Add the ability to freeze a frame clock, which pauses its operation,
then thaw it again later to resume.
Initially this is used to implement freezing updates when we are
waiting for ConfigureNotify in response to changing the size of
a toplevel.
We need a per-window clock for this to work properly, so add that
for the X11 backend.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
Instead of having gdk_frame_clock_request_frame() have
gdk_frame_clock_request_phase() where we can say what phase we need.
This allows us to know if we get a frame-request during layout whether
it's just a request for drawing from the layout, or whether another
layout phase is needed.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
We may receive events because SubstructureNotifyMask has been selected
for the root window. (Most likely, this would occur because GTK+
is being used inside a window manager like Metacity or Mutter.)
This can confuse various types of internal accounting, so detect
such events and comprehensively ignore them for GDK's internal
purposes. We still need to generate GDK events for these cases
because you can select for substructure events with
GDK_SUBSTRUCTURE_MASK.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
This adds a way to get the gtk_widget_set_opacity liike behaviour
of retargeting GdkWindows and exposing every child in ::draw, without
actually having an alpha. This is needed if you're doing more complex things
such as cross fading of widgets.
We do this as a hack by using opacity values that round to 255 yet not
really 1.0 in order to avoid having some magical API call for this
mainly internal call.
https://bugzilla.gnome.org/show_bug.cgi?id=687842
Some backends do not have slave devices, which means last_slave may be
NULL. Use the current device as the source device if last_slave is NULL
when synthesizing a crossing event.
https://bugzilla.gnome.org/show_bug.cgi?id=692411
Sink the GtkEntry assigned to the private structure of GtkCellRendererText
before signals containing it as an argument are sent out. This keeps
language bindings from sinking the reference and then destroying the entry
when the signal closure is finished.
https://bugzilla.gnome.org/show_bug.cgi?id=693400
When calling gtk_widget_draw() on the entry gtk_cairo_should_draw_window()
will return TRUE for all windows. This is used when rendering a widget to
somewhere other than the screen, and its now used for transparent widgets.
This caused the texthandle to always draw itself and terminate the draw
handler for the entry.
Instead we now only draw the markers when really visible, plus we return
FALSE to avoid stopping the entry drawing.
https://bugzilla.gnome.org/show_bug.cgi?id=687842
This adds gtk_widget_get/set_opacity, as well as a GtkWidget.opacity
property. Additionally it deprectates gtk_window_get/set_opacity and
removes the GtkWindow.opacity property (in preference for the new
identical inherited property from GtkWidget, which should be ABI/API
compat).
The implementation is using the new gdk_window_set_opacity child
window support for windowed widgets, and cairo_push/pop_group()
bracketing in gtk_widget_draw() for non-window widgets.
https://bugzilla.gnome.org/show_bug.cgi?id=687842
This replaces the previously hardcoded calls to gdk_window_set_user_data,
and also lets us track which windows are a part of a widget. Old code
should continue working as is, but new features that require the
windows may not work perfectly.
We need this for the transparent widget support to work, as we need
to specially mark the windows of child widgets.
https://bugzilla.gnome.org/show_bug.cgi?id=687842
We now store the current opacity for all windows. For native windows
we just call into the native implementation whenever the opacity changes.
However, for non-native windows we implement opacity by pushing a
second implicit paint that "stacks" on the existing one, acting as
an opacity group while rendering the window and its children.
This works well in general, although any native child windows will of
course not be opaque. However, there is no way to implement
implicit paint flushing (i.e. draw the currently drawn double buffer
to the window in order to allow direct drawing to the window).
We can't flush in the stacked implicit paint case because there
is no way to get the right drawing behaviour when drawing directly
to the window. We *must* draw to the opacity group to get the right
behaviour.
We currently flush if:
* A widget disables double buffering
* You call move/resize/scroll a window and it has non-native children
during the expose handler
In case this happens we warn and flush the outermost group, so there may
be drawing errors.
https://bugzilla.gnome.org/show_bug.cgi?id=687842
_gdk_display_device_grab_update does not support passing in NULL for the
source device. If we don't have a slave device (saved in the pointer info)
then do not try and use that NULL pointer for the source_device.
This bug appeared in the Wayland backend where we (currently) only have master
devices exposed and as such no slave device is ever saved.

This reverts commit cd98eb15cb.
It turns out that we just started using AX_PROG_CC_FOR_BUILD, which
for some reason requires AC_CANONICAL_TARGET. That seems wrong to
me, but for now, lets just keep using it.
This autoconf macro should only be used for building compilers
(or compiler tools) for a specific target. The current effect of
it in GTK3 is that it causes various executables like gtk3-demo
to be prefixed with $target- when the --target configure flag
is set or when cross-compiling. When cross-compiling GTK3 on
Linux for the Win32 target this causes the gtk3-demo binary
to be named i686-w64-mingw32-gtk3-demo.exe instead of just
gtk3-demo.exe (like it was before commit 53083ea7b4)

Commit ddceddaa84 removed the call to
gtk_style_context_set_background() in favour of always rendering it with
gtk_render_background() during the draw vfunc.
This has the side effect of making the backing window always

the paint cycle. The result is that, especially in clutter-gtk
applications, scrolling performance gets really bad.

gtk_tree_drag_source_drag_data_get's GtkSelectionData argument should not be
marked as (out) because:
a) GtkSelectionData is semi-private (it's declared in gtkselectionprivate.h),
and thus gobject-introspection has no knowledge of its fields or its size.
There is thus no way for language bindings to allocate GtkSelectionData.
b) Even if it was possible for language bindings to allocate GtkSelectionData,
a zeroed-out instance thus created would not be usable with
gtk_tree_drag_source_drag_data_get. As far as I can tell, you need to
initialize its "target" member to the GdkAtom of "GTK_TREE_MODEL_ROW".
Language bindings have no way of knowing this, of course.

This is a quickfix to keep things working.
It turns out GtkWindow assumes it can do sizing operations while not
being visible, or while in the process of show()ing/hide()ing itself.
And commit b495ce54 broke these operations.
Figuring this properly requires some more thinking and restructuring on
my part, so for now we relax the requirement of visiblility enough for
these things to start working again.

This adds a PlatformToolset tag in the project configs so that we can
provide support for Visual Studio 2012 with relative ease as the format

We can then use a script like the one used in GLib[1] to copy the VS2010

This also cleans up the projects and property sheets, as there were some
unwanted/unneeded entries in them.

In the Wayland backend implementation for gdk_display_get_keymap we enumerate
the known devices and look for an core keyboard device. These device objects
are created when we receive the capabilities for the seat. The seat
capabilities may be received after a request for the keymap so we handle this
by creating a temporary keymap which we then free later when we have the real
one.
An instance of GtkAdjustment may be used by another instance after
the spin button widget is destroyed. In that case, the function
gtk_spin_button_accessible_value_changed() will be called with an
invalid argument. This situation is often caused when one use

the signal handler for the "value-changed" signal should be disconnected
when the spin-button widget is destroyed.
Using g_signal_connect_object achieves just that.

width-chars and max-width chars should (and do) only change the

This came out of an IRC discussion, so no bug.
The underlying code uses API that is no longer available with 1.0. This
optional, off by default build mode hasn't worked since the release of
Wayland 1.0.
There are cases where crossing events aren't generated by input devices themselves
but rather through programmatical means (windows being moved/hidden/destroyed while
the pointer is on top).
Those events come from X as sourceid=deviceid, and GDK does its deal at lessening
this by setting a meaningful source device on such events, although this caused
some confusion on the mechanism to block/synthesize touch crossing events that
could possibly cause bogus enter events on the new window below the pointer.

Since 16195ad the “expand” property is always set to FALSE when a
column is resized. This commit takes a different approach and enables
“expand” whenever the column is wide enough. An appropriate
“fixed-width” (so that the desired width is achieved after expanding) is
calculated using equations that are explained in the code.
https://bugzilla.gnome.org/show_bug.cgi?id=691751
Rewrites gtk_tree_view_column_request_width() and
gtk_tree_view_size_allocate_columns() to respect the minimum and natural
sizes that are already being returned by
gtk_cell_area_context_get_preferred_width().
The convoluted logic explained (not!) by this comment has been removed:
“Only update the expand value if the width of the widget has changed, or
the number of expand columns has changed, or if there are no expand
columns, or if we didn't have an size-allocation yet after the last
validated node.” This logic seems to have been a workaround for the
“jumping” behavior fixed in 16195ad and is no longer necessary.
https://bugzilla.gnome.org/show_bug.cgi?id=691751
Removes the hidden “resized-width” and “use-resized-width” properties
from GtkTreeViewColumn and instead uses the “fixed-width” property to
serve the same purpose. “fixed-width”, if set, will now override the
auto-sized width (-1 is now a legal value meaning “not set”).
Additional “cleanups” in this commit:
1. When the user resizes the column the “expand” property is now also
set to FALSE, in order to prevent the column from suddenly jumping to a
different width when the window is resized.
2. The code that translated mouse movement to column sizes has been
simplified:
the change in column width is now calculated directly from the distance
the mouse cursor has traveled. Weird behavior that might have happened
previously if the position of the column changed during resizing, is now
prevented.
3. There was some lengthy logic handling the keyboard shortcuts used to
resize treeview columns, which would call gtk_widget_error_bell() once
the minimum or maximum width was reached. Instead of rewriting these
checks I simply set the “fixed-width” property to what was requested,
relying on the fact that it is already clamped between the minimum and
maximum width during size allocation.
I will greatly surprised if anyone notices the missing error bell.

Splits up size_request() so that the height calculations are only done
when get_preferred_height() is called and the width calculations are
only done when get_preferred_width() is called. Since
get_preferred_width() does not change the treeview->priv->width value,
treeview->priv->prev_width will always be equal to it and can therefore
be removed. The only place where prev_width was used is a block in
gtk_tree_view_size_allocate(). This block seems to be adjusting the
horizontal scrollbar to account for treeview->priv->width having been
changed in size_request() and should no longer be necessary. A similar
block immediately above it seems to already account for the width change
in size_allocate().
https://bugzilla.gnome.org/show_bug.cgi?id=691751
After “validation” (i.e., background size calculations) of some cells,
size_request() was called here to update the internally cached size of
the treeview. Apparently not updating the sizes leads to some kind of
“inconsistency” that messes with top_row_to_dy(). In the GTK3 model for
size allocation, things are more complicated. The treeview can’t just
go ahead and calculate its own size any more; instead it reports both a
“minimum” and a “natural” size, and it doesn’t know what size it will
actually get until size_allocate(). It may be necessary to update
top_row_to_dy() to deal with not knowing the exact size.
https://bugzilla.gnome.org/show_bug.cgi?id=691751
We want to reserve space for the size of the scrollbars even when they
are not visible. And because toggling visibile to off now returns 0 for
size requests, this won't work anymore.
The window size can be queried on widget->window directly, no need to
store it in widget->allocation.
This change is necessary because gtk_widget_set_allcation() is now
checking invariants that assume it's called from insize
gtk_widget_size_allocate() and that wasn;t the case here.
Commit e32da246a8 made GtkRange's trough
respect the CSS margin property, but it also trimmed the box in which
the trough reacts to click events by the margin.
We still want to catch events in that area instead, and just make sure
the margin is applied when drawing (which was already implemented by
that commit).
This commit reverts the parts of
e32da246a8 that didn't involve drawing,
fixing the bug.

Before acting on any hint that is set by the window manager we must
first check that the hint is supported by the current window manager.
Checking that a property has a value is insufficient as it may have
been set by a previous window manager which did support the hint.

When cross-compiling, instead of depending on a natively built GTK+ (which means
building Glib, ATK, Pango, gdk-pixbuf, libX11...) for gtk-update-icon-cache,
find the host compiler and gdk-pixbuf, and build another gtk-update-icon-cache
with that.
This uses AX_PROG_CC_FOR_BUILD from autostars to find the host compiler, and
assumes that you'd set PKG_CONFIG_FOR_BUILD to a host pkg-config binary.

With this we always roundtrip position change to the webbrowser.
This avoids conflicts when things change from both directions (app and user).
Also, we fake configure evens when there is no web client to ensure
apps get the events.
GtkWidget::visible is required for the widget to:
- have a preferred size other than 0/0
- have a size allocated
- return other values than { -1, -1, 1, 1 } from get_allocation()
This is an experimental patch aiming to make concepts and behaviors
inside GTK more concreate. GtkWidget::visible is now essentially what
CSS does for "display: none".
Note that if you want the effect of CSS's "visibility: hidden", you'll
have to use a GtkNotebook with an empty page as the concept of reserving
space but not drawing anything isn't supported natively in GTK.
It's a lot uglier now, but it shouldn't crash anymore.
We must update the font description for animations, but we can't free it
on query, because some paths call gtk_style_context_get_font() twice in
a row without stopping the use of the first call. So us just creating a
new font description all the time and unreffing the old one is not a
good idea. So we just mere the new one into the old one.
https://bugzilla.gnome.org/show_bug.cgi?id=691186
Previously, with STATE_FLAGS_REPLACE we would unset _all_ the state
flags on children, not just the ones that do propagate. This caused the
RTL/LTR flags to get lost.
This is a trivial example. Just check that we can derive
from GtkButtonAccessible, and have a GtkButton subclass
use the derived accessible implementation.
We add a separate gtk-a11y.h single-include header for
them. This header will work much the same as gtkx.h. It
will be installed in /usr/include/gtk-3.0/gtk, but you
have to include it separately.
Since we are going to install these headers soon, we need
to make their mutual includes work in the installed location
as well. Also, avoid including individual gtk headers, to
avoid trouble with single-include guards.
This commit exposes the get_type() functions and standard
headers for accessible implementations. This makes it possible
to derive from the GTK accessible implementations without
GType magic tricks. This is necessary, because we require the
a11y type hierarchy to be parallel to the widget type hierarchy.
So, if you derive a widget and need to adjust its a11y implementation,
you have to be able to derive its accessible implementation.
This commit probably exposes more than is absolutely necessary,
it also exposes accessibles of widgets that are unlikely candidates
for deriving from.
Since not every theme renders a background for a GtkViewport (and
Adwaita master doesn't), ensure the grid+viewport we use to emulate a
text view here uses the "view" style class.
It already paints the css border, so let's make it also honor css
background. This is needed to have a box of a different color around
some widgets (e.g. latest gnome-clocks design)
This (shouldn't) change any behaviour, but it moves the
webserver parts to a separate file, making the broadway display file
smaller and preparing for later separating out the server to its own
process.

This function is just a sophisitcated optimization.
If we know the GDK window's background will be opaque, we mark it as
opaque. This is so GDK can do all the optimizations it does for opaque
windows and be fast.
This is mainly used when scrolling.
The previous code didn't get this right, in particular it didn't enforce
a transparent background when it knew the background was not opaque.
The code path where we update the tooltip text property doesn't set
the state and value variables, and so doesn't need to call
notify_state_change().
Return early, and move the if block at the beginning of the function for
clarity.
There are some registred stock ids like gtk-discards that have no icons,
and you could also pass a non-registred stock id. Both of these means
gtk_style_context_lookup_icon_set returns NULL, which causes
a critical in gtk_icon_set_render_icon_pixbuf.
We avoid this by just making these render as EMPTY.
In gtkimcontextime.c, use gdk_win32_window_get_impl_hwnd() to get to
the impl's existing native window instead of GDK_WINDOW_HWND() which
implicitly ensures a native window for the widget itself. This seems
to work around whatever GDK problem with native subwindows and fixes
the bug.
This is based on Michael Natterer's fix for gtk-2-24.
We used to use GTK_RESIZE_QUEUE, but that is problematic for e.g
a GtkScrolledWindow with NEVER scroll policies, as size changes
in ancestors will never get propagated to the scrolled window, causing
it to not have the correct size.
This is a slight performance hit, but in practice its not bound to be
problematic. In typical UIs there is only a single "large" GtkScrolledWindow
visible at a time, so a size requeust propagating out of such a window
will only hit the smaller amount of widgetry outside the scrolled window,
and additionally all such widgets will have their size request caches
still valid.

We don't get an automatic queue resize on realize anymore, which
was papering over this bug where we did not set the child window
size/position at realize time.
We use the new g_type_get_type_registration_serial() so that we can

Rather than first collecting matches and then getting the change
for them we do the change collection directly on the tree. This
is about twice as fast.
At the moment, gtk+ doesn't depend on intltool, which is the program

We must not release the GtkClipboardOwner in pasteboardChangedOwner
becaue we don't own a reference to ourselves (NSPasteboard does).
Instead, release the owner right after setting it, transferring
ownership to NSPasteboard
Also, fix repeated setting of the same owner by keeping the
owner around in GtkCLipboard, and re-use it if "user_data"
doesn't change. To avoid clipboard_unset()ting our own contents
in the process, add an ugly "setting_same_owner" boolean to
GtkClipboardOwner, set it during re-setting the same owner,
and avoid calling clipboard_unset() from pasteboardChangedOwner
if it's TRUE.
(cherry picked from commit 4a8df7a33c)
We currently invalidate the whole tree every time the style state
changes in the tree view. The primary reason for this is to catch
default font changes as that may affect text cell renderers. But
cell renderers could *potentially* also read other style properties
(although that seems weird and unlikely).
We handle this by invalidating only when some state that affects sizes
is changed. This includes all the font properties.
With pango handling changes to the PangoLayout there now is no
style changes that can affect the layout for the entry, so we don't
have to reset the layout whenever the style is updated.
Now that Pango tracks changes to the context automatically there is
no need to do it manually in e.g. style-updated or direction-changed,
in fact the only case we have to care about is when we re-create
the PangoContext due to a screen change, so we only have to clear
the layouts in GtkLabel in screen-changed.
This means we're not clearing all the layouts whenever the state changes,
which happens to every widget when the window is unfocused, which helps
performance a lot.
https://bugzilla.gnome.org/show_bug.cgi?id=340066
Pango 1.32.4 has a feature where any PangoLayout automatically handles
the case where a PangoContext is changed. We want to rely on this to
avoid having to clear layouts too often, so we make this a hard dep.
This is for a very simple reason: The getter is returning a const value
and the font isn't const anymore. So we need to store the font
description somewhere but we can't reuse it as it's changing all the
time (yay animations, yay inherited values). Sucks.
So keep the hack in here but deprecate the function.
Instead of using gtk_style_context_get_font() in
pango_context_get_metrics(), use pango_context_get_font_description().
The context contains the font description we are about to use after all.
This is necessary because values in a GtkCssComputedValues can change
now. So if the font-size is inherited or animated, the cached value will
be outdated.
Fixes the fontchooser preview not updating.
This means reffing the root in the set property implementation,
rather than in the constructor. We don't need to unref the root
on set, as it's a CONSTRUCT_ONLY property.

GtkWindow always queues a resize on style updates if there is
a grip, because it may have been the grip size style properties
that changed. However, even if it *were*, and it likely wasn't
that would not affect the windows size request, so no need
to queue a resize.
queue_resize basically tells the parent widget that it may need
to pick a different size/layout. However, for a hidden child widget
that should never be needed. It may be that the widget is in a
sizegroup that has ignore_hidden == FALSE though, so it may
affect the size group calculations.
However, if a widget is not visible and not in a size group then
its safe to avoid the resize, as the widget will be resized on
becoming visible anyway.
This avoids a lot of size allocation for hidden things like menus
and tooltips.
Almost all array computations lead to no changes (99% in nautilus)
so we avoid the upfront allocation and delay it until we know its
needed. This drops the allocate/free from the profile.
These are internal apis, and any external issues should have been
caught by checks at public API points. We use the internal checks
here because these checks show up in a non-neglible way on profiles.
pasteboardChangedOwner is not called as reliably as we'd want to get it,
so keep track of [pasteboard changeCount] and drop clipboard ownership
when a change happened. Also better unset the clipboard content redundantly
in a few places rather than missing one, and reorder the code in
gtk_clipboard_set_contents() so that the new aggressive unsetting
won't unset the clipboard under our feet when we call
[pasteboard declareTypes].
(cherry picked from commit f2b74db5dc)
We now support the keywords (like xx-small, medium, larger, smaller...)
and I've changed the default value to be "medium".
This required some shuffling of the "get default font size" code. But
all is well now.
The default font is no longer handled like a custom style sheet that
overrides everything, but as the initial value. This is the same
behavior as in web browsers.
And it allows the theme to actually use the 'font-family' and
'font-size' properties. Of course, a well behaved theme will respect the
setting as much as possible and for example use relative font sizes
(which aren't yet supported, but will be soon).
This gives a GtkSettings object for resolving system-dependant things -
like the default font family and font size.
No code does this yet, but we have an API.
Only GtkSettings implements this.
The new css tree may change the order of selectors (keeping the
same semantics). This affects how the selectors are printed later,
which causes some css parsing tests to not match the references.
Fortunately the order is consistent between runs given the same
css, so we just have to switch around the order in some of the
.ref.css files.
Now we use the selector tree everywhere, so there is no need to
keep around the linear selectors unless we're using them to
verify the tree correctness, so free them.
We add some "artificial" ordering to the otherwise unordered
tree nodes. This means the tree will be the same every time for the
same input. This is good because e.g. tree order affects the
reordering of the simple selectors, which may affect how
css providers are printed, which need to be consistent for
the css tests to work.
When building the tree we generally reorder the selectors inside
the same simple selector in order to pick a good first selector
to balance the tree better. However, some kinds of selectors
can't really be reordered, even thought they are simple.
This is since the matching code for some types handle
the existance of a directly preceeding selector differently:
REGION and ANY selectors look for a DESCENDANT previous
POSITION selector look for a REGION previous
From a set of GtkCssSelectors and the rulesets they match to
we create a large decision tree that lets us efficitently match
against all the rules and return the set of matched rulesets.
The tree is created such that at each level we pick the initial rule[1]
in all the considered selectors for that level and use put the
one that is in most selectors in the node. All selectors matching that
are put in the previous part of the tree.
This returns true if the matcher matches *anything*. We need
to check this later, because such matchers are dangerous in loops
that iterate over all parents/siblings since such loops would not
terminate.
With the previous commit all loads of the same icon will share a single
GtkIconInfo, which typicallty means the pixbuf is shared via Info->pixbuf.
However, atm we don't share symbolic icons, which causes these to be re-read
and re-parsed every time. This is especially bad if the icon is used many times
in some form of list. So, we cache the pixbufs and reuse them.
https://bugzilla.gnome.org/show_bug.cgi?id=689081
In order to avoid loading and keeping around the same icon multiple times
we keep a cache of all outstanding GtkIconInfo objects for a given theme.
Additionally we return to the app not the normal pixbuf from the info,
but rather a proxy copy of it sharing the same data, but no extra
reference. This allows us to track when the app is no longer using
the pixbuf, and we can thus ensure that the GtkIconInfo in the cache
stays around for at least as long as the pixbuf is alive.
When the app unrefs the pixbuf we put the Info on a short LRU list
to keep it alive a bit longer, in case the app needs it in a short
while.

Symbolic colors are an implementation detail of the CSS engine and have
been superceded by GtkCssColorValue. We don't want them clobbering the
public API. In particular because the only use I could find in the
public API is people using it to shade colors.
Make _gtk_style_provider_private_get_color() return a GtkCssValue (a
GtkCssColorValue to be exact) instead of GtkSymbolicColor.
With this, the symbolic color usage inside GTK is minimized.
The documentation for gtk_file_chooser_get_filenames() states that the

absolute paths.

Most GtkBin subclasses override this strange garbage anyway, so it's
not like this code is ever *run*, per se. Just make it proxy directly
to the child, and hope nothing goes wrong.
Implement get_preferred_width, get_preferred_height, and size_allocate.
This allows GtkBin subclasses to be quick and easy, without the
author doing the subclassing to have to do much work.
If the "wider" label is the smaller one, use the wider size for both
cases. This can happen when ellipsizing a single character, which is
often smaller than the ellipsizing glpyph(s).
Functions should not have a space before the opening parenthesis. So
change output like
alpha (@color, 0.5)
to
alpha(@color, 0.5)

Tests have been updated accordingly.
This is so newer versions of those libraries don't cause more warnings
with a stable GTK version.
We don't ever want to turn off deprecation warnings for master however,
because that's where we get rid of deprecated API we use.
Note that only glib allows use to easily do this, so nothing is done for
Pango, gdk-pixbuf or Cairo here.
With ellipsizing, the ellipsized text can have a smaller height than the
non-ellipsized text. So the wider text is also higher. Example:
.<big>TEXT</big>
will ellipsize to the small text.

We must make sure to remove the weak pointer when disposing the widget

This way we don't need a marker on GtkWidgetParivate that needs to be
unset later, so we have all our data in the same place and can avoid
problems with reentrancy and shenanigans like that.
But the main reason I wrote that is cleaner code.
With this function now available, we can do size computation in 2
ways:
(1) Compute size with size groups
(2) Compute size without size groups
And have (1) use (2) instead of setting flags on widgets. This patch
does exactly that.
With size groups now doing hfw, doing the optimization for CONSTANT_SIZE
was done too early. Size groups need to know that it's a hfw request, so
the other widgets in the size group get the correct behavior.
The label code assumed that Pango treats this as "wrap to as much space
as possible and then ellipsize all the lines", but for Pango, ellipsize
takes precedence over wrap. So do the same thing in GtkLabel.
Also updated is the reftest that checked this behavior.
Get rid of all the event boxes in this test. Event boxes need GDK
windows which cost a lot of performance when running the test and they
clip the label output.
Getting rid of the clipping also shows 2 bugs in this test that weren't
visible before. Those will be fixed in a followup patch.
We compute on-demand for size groups anyway, so we can (in theory, this
patch doesn't do that yet) get around costly cache blowing when
invalidating single widgets of a size group this way.
The current approach of using gtk_widget_get_mapped() is broken:
The usual steps taken when showing a window are:
(1) request the sizes
(2) allocate the sizes
(3) show the window in the allocated size
Showing the window with a random size between steps (1) and (2) would of
course
result in extra work and potential flickering when the widgets get
resized to
their proper sizes.
However, as GtkSizeGroup::ignore-hidden uses gtk_widget_get_mapped() to
determine visibility for a widget, the following will happen:
(1) the widget will request a 0 size
(2) the widget will be allocated a 0 size
(3) the widget will be too small when it is shown
gtk_widget_get_visible() however is set in advance. Note that toggling
visibility also causes a gtk-widget_queue_resize() call already so we
take care of changes in here automatically.
Instead of only checking the ignore_hidden flag when getting the
preferred sizes, respect it already when constructing the list of
widgets. This way, widgets don't queue resizes for groups they're
ignored in anyway.
For loops to loop over lists look nicer and actually do the right thing
with "break" and "continue" statements. So they are vastly preferred to
while loops.
This simplifies code and because sizes are cached by the widgets
themselves, it's not a large performance problem (unless people use huge
amounts of widgets in a single size group, but who does that?
The main problem is that we were emitting the row-deleted signal for the model in the middle
of the process that actually deletes the row from the model (remove the row from the array,
update the model->file_lookup hash table, etc.). In the model's caller, one of the row-deleted
callbacks was requesting an iter, which caused the model to revalidate itself - but it did
this while it was in an inconsistent state. This led to an assertion failure later when the
model resorted itself.
The fix in remove_file() is like this:
* The filteredness/visibility of the deleted node is not updated. The
node will simply be gone; we don't need to update those values at
all.
* We invalidate just the node that is being deleted.
* The model->file_lookup hash table is not completely nuked; instead,
we carefully adjust its indices.
* The row-deleted signal is only emitted at the very end, when
deletion is complete and the model is consistent.
Many thanks to William Hua for doing the detective work on this bug!

They were in the semi-public API of GtkFileSystemModel, but never actually used outside of it.

This is a function internal to the file system model; let's not pollute the gtk_tree_path namespace.
Also, make the 'i' variable into 'r' as it refers to a row index, not a file-array index (for
consistency with the docs and the rest of the code).

Right now we support loading and recoloring symbolic GFileIcons, but
only if the underlying GFile has a local path. This breaks when the
GFileIcon is loaded from a GResource, which is a reasonable option for an
application that wants to ship a custom symbolic icon.
This patch changes GtkIconInfo to store a GFile together with the file
path, and changes the symbolic icon lookup code to use the GFile URI,
which transparently makes the code work also for GResources.

Move variable initialization outside the first code with side effects.
This allows adding some more early returns, including one for code that
used to trigger g_return_if_fail() in certain corner cases.
Old code tried to use the "background-image" proeprty for setting the
default image background. While this used to work in the early days of
GTK3, today it is grossly misleading as the backgronud image may be
resized, repositioned and semi-translucent which causes very weird
artifacts when rendering.
So we use the background-color only instead.
This way we create one provider per settings object instead of stuffing
it into a global unchanging never-deleting hash table.
Also, we now reload the theme when instructed instead of keeping the old
loaded (and possibly stale) data forever.
https://bugzilla.gnome.org/show_bug.cgi?id=683896
This makes sure the full theme loading logic resides in one function and
isn't scattered around.
As a side-effect, the hash table kept by gtk_css_provider_get_named()
will now be populated with fallback themes. This will not be a problem
after the next commit though.
Split maintaining the global themes hash table and the theme loading
code into two functions.
This also fixes leaking the provider when loading a theme from a builtin
resource.
libxkbcommon has had some changes to its API. However, it now has a
stable release (0.2.0), so this makes the necessary changes, and
replaces all uses of the deprecated API.

Themes may want to render handles differently depending on whether
the widget is in selection mode (2 handles enclosing a selection) or
cursor mode (one handle pointing out the insertion cursor).
This improves both interaction and theming, as it allows
arbitrary handle shapes while just being draggable from
the visible areas.
This way themes can set up handles with the hotspot visually
displaced from the horizontal center, as long as the hotspot
lies centered in the image/svg asset.
The check on the handle to be drawn on the mask was based on the yet to
be set priv->windows pointers, pass explicitly the handle position to
have the shape correctly initialized on non-composited environments
The GtkNotebook drag-motion event handler may install a timeout when
hovering over a tab, in order to switch to it.
On the other hand it's desirable for applications to use the empty tab
area as a drop target, so the drag-motion handler returns FALSE
(also in case it installs the switch tab timeout), as explained in
https://bugzilla.gnome.org/show_bug.cgi?id=350665.
Unfortunately, applications can use the tab label widget (or a child
of it) as a different drop target area, and install their own
drag-motion handler there.
In this scenario, the timeout will still be installed by GtkNotebook's
handler, but since it returns FALSE, it will never get the matching
drag-leave event, causing it to trigger also when the mouse pointer
moved elsewhere before it expired.
Fix this by returning TRUE from drag-motion when the event is over a
tab. Note that this makes automatic tab switching not work anymore when
drag and drop is handled in the tab label widget; applications are
expected to also handle tab switching if desired in such a case.

GtkScrollbar used to rely on style-updated being emitted every time
after the widget was created in order to set the right values from its
style properties on GtkRange.
Nowadays we try to be smarter and avoid emitting style-updated at
creation time, so we need to manually initialize the GtkRange values.
This fixes a regression from 35e36b9fe5.

Currently we use gtk_style_context_set_background() when the state flags
change in order to propagate the background color to the overshoot
window, but this is actually only needed because the window doesn't get
expose events, since we always draw a full background in draw().
This also fixes some problems when the GdkWindow of the scrolled
window's child is composited, as seen in oxygen-gtk3.

The implementation of transition for GtkCssShadowValue can return NULL
at least when the two values have a different inset; all other parts of
the GTK/CSS machinery (e.g. GtkCssArrayValue) handle this by returning
NULL too. Instead, GtkCssShadowsValue was returning an invalid value,
where "len" was set, but some values in the array were NULL, which would
lead to a segfault when this value is later evaluated by the compute
function.
Fix this by making GtkCssShadowsValue return NULL if a shadow transition
fails, like GtkCssArrayValue does.

Don't use a repeating linear gradient, since it can't be easily
reftested against a non-repeating one for the reasons described in the
test header.
Instead, add a separate test for repeating gradients (against another
repeating gradient).
This makes the test pass, so it can be added to the Makefile now.
