Whenn setting gtk_builder_set_allow_template_parents(), the builder
instance will accept
<template class="GtkWidget">
for a GtkBox instance.
It's going to be used with the new GtkColumnViewCell objects, so that
it's backwards compatible with ui file factories that use GtkListItem.
That way, local scrolling is available and the scrolling isn't random.
Recycling should now involve reordering the recycled widgets instead of
just keeping their order because all of them got recycled.
This allows setting a factory to toggle per-row properties.
Implemented are selectable, focusable and activatable.
These are meant to supercede the per-cell selectable and activatable
properties, which make no sense individually.
The focus property makes it possible to focus rows instead of cells,
which is the default behavior.
There is no way to set it yet, this is just to prove that it works.
It also changes the focus behavior of rows. They are now always
focusable - unless turned off by the factory once that is possible.
This makes the question if a listitem can be focused or not an explicit
decision by application developers.
Previously an item could be focused if it was selectable and no child or
grandchild was focusable - so if you put a label and icon into it, the
item was focusable, but if you put a GtkTreeExpander or a GtkButton into
it, the item wasn't. This needs to be decided explicitly now.
Technically this is an API break, because the previous behavior does not
exist anymore.
But I really don't want to make this a tristate (focusable, not
focusable, automatic), because then binding it to other things gets
hard, and because all the other focusable proeprties are booleans, too,
and working with them gets a lot harder.

Cairo can do that, so just enable it:
* Create surfaces with the correct fractionally scaled size.
* Set the Cairo surface's device scale to that number.
Instead of setting the buffer scale via the buffer-scale command, set it
via the viewport.
This technically allows setting fractional scales, but we're not doing
that.
Instead of tracking a single scale, track x and y scales separately.
Factor out gsk_vulkan_render_pass_new() into a private function that
receives both scales, and pass 'scale_factor' for both.
April fools!
No, really.
The fractional scale protocol is just a way to track the surface scale,
but not a way to draw fractional content.
This commit uses it for that, so tht we don't rely on tracking outputs.
This also allows magnifiers etc to send us a larger (integer) scale if
they would like that, that is not represented by the outputs.
This is mostly a cosmetic change, and the goal is twofold:
1. Make it easier to spot unimplemented render node types; and
2. Prepare for a small rework
The implementation for each node now lives in specific functions,
like the GL renderer; unlike the GL renderer, however, we use a
node type vtable to map GskRenderNodeType → implementation. Render
node without an implementation map to NULL, and use the fallback
implementation. Render nodes that fail any check and return FALSE
also use fallback implementation.
The scrolling code assumes the adjustment values are up to date or
it crashes and before we've run size_allocate() we haven't update them.
Fixes a crash in the gtk-demo scrollinfo that would set the adjustments
with random values (via ScrolledWindow.set_child()) and then scroll in a
tick callback right before the (first) size_allocate().
The Lunarg validation layers seem to have been deprecated in favour
of the Khronos ones. There's no reason not to have both, to accept
loading both - simultaneously, even.
Instead of passing a single, potentially massive rectangle that is
just the extents of the damage rect, collect and pass all damage
rects individually.
Add a new flag to track whether buffer scale is dirty or not,
and centralize calling wl_surface_set_buffer_scale() in a single
place: gdk_wayland_surface_sync_buffer_scale().
gdk_wayland_surface_sync_buffer_scale() is only called by
gdk_wayland_surface_sync(), which itself is called by the GL,
Vulkan, and Cairo contexts, right before submitting a frame.
This ensure that each frame has an up-to-date buffer scale.
This mimics how opaque and input regions are tracked.
According to the at-spi2 docs, for a widget to be considered visible,
it needs both the showing and visible states. Many applications rely on that,
for example the flat review functionality of Orca.

Don't fudge around poking through the listview, trying to get a model
and selecting it directly. Instead, use the proper way and activate the
"listitem.select" action.
Instead of directly calling select_item(), trigger the select-item
action of the focused child.
We do this convoluted calling into the widget because that way
GtkListItem::selectable gets respected, which is what one would expect.
Plus, this code is usually triggered via keybindings, and this way the
ListBase keybindings work identical to the ListItem keybindings.
If we encounter a node or texture the 1st time and they are going
to be used again, give them a name.
Then, when encountering them again, print them by name instead
of duplicating them.
We extend the syntax for nodes from:
<node-type> { ... }
to
<node-type> { ... }
<node-type> <string> { ... }
<string>;
where the first is the same as before, the 2nd defines a named node and
the last references a previously defined node.
Or to give an example:
color "node" {
bounds: 0 0 10 10;
color: red;
}
transform {
bounds: 20 0 10 10;
child: "node";
}
This will draw the red box twice, once at (0,0) and once at
(20,0).
The intended use for this is both shortening generated node files as
well as allowing to write tests that reuse nodes, in particular when
dealing with caches.
We extend the syntax for textures from just:
<url>
to
[<string>] <url>
<string>
where the first defines a named texture while the second references a
texture.
Or to give an example:
texture {
bounds: 0 0 10 10;
texture: "foo" url("foo.png");
}
texture {
bounds: 20 0 10 10;
texture: "foo";
}
This will draw the texture "foo.png" twice, once at (0,0) and once at
(20,0).
The intended use for this is both shortening generated node files as
well as allowing to write tests that reuse textures, in particular when
mixing them in texture and texture-scale nodes.
If we map, reposition, unmap, remap, the reposition feedback from the
last time a popup was mapped might be received while we're dealing with
the new version of the popup. At this point, the old reposition token
has no meating, so lets drop it. Also reset the reposition tokens when
creating new protocol objects, so that the reposition token are as if
we're in the initial state.
This fixes an issue where we'd get stuck if repeatedly smashing a button
that'd create popups that'd immediately get dismissed by the compositor.
Since Wayland 1.15, it is now possible to use absolute paths in
"WAYLAND_DISPLAY".
In that scenario, having a valid "XDG_RUNTIME_DIR" is not a requirement
anymore.
For this reason we remove the "XDG_RUNTIME_DIR" check and we let
`wl_display_connect()` decide if our environment is correct.

An inert gridview is a gridview that does not use the factory. This
allows faster updates because no calls into user code need to happen.
A gridview is inert when either:
- It is not rooted.
- It is not visible.
- No factory is set (that one is obvious)
The gridview does not need to be inert without a model, as that case is
handled by the item manager.
This should allow Nautilus to keep both the gridview and the columnview
around, and just gtk_widget_hide() the unused widget.
The code for now does not disable the item manager, as some
functionality of the item manager is required to allow setting scroll
positions and such.
But that is a place where more gains could be found if profiling showed
that was useful to do.

The widget would teardown the factory on unroot to avoid unnecessary
work when it isn't shown.
However, recycling may reposition widgets, and repositioning widgets
does a unroot/root.
We don't want to recycle widgets then.
The implementation lives (as always) in GtkListBase.
This is a feature request from the Nautilus developers, who currently do
some hacks to emulate that behavior and it apparently only breaks
sometimes.
We connect gtk_scrolled_window_update_use_indicators
as signal handler in realize(), but we were disconnecting
gtk_scrolled_window_sync_use_indicators in unrealize.

Just like GdkToplevel::compute-size, the size argument of the signal is
given to the handlers by GDK; it's not an out argument meant to be
allocated by the caller.
The size argument is passed to the signal by the GDK surface machinery,
as is: it's not going to be allocated by the caller (since it's a
signal), and it's not an out argument.
The cursor-theme-size setting is documented as
'0 means the default size'. Make it so by using
size 24 if we see a 0. Its better than crashing.
Fixes: #5700
The function is going away, and the computation
here was wrong anyway. Instead, add a helper that
properly computes the pointing-to rect in surface
coordinates and use it everywhere.
The widget paintable uses the widgets bounds
as intrinsic size, so we need to offset from
that to the allocation, which is what the
coordinates are relative to.
Text handles had the same problem as popovers.
They were interpreting their pointing-to rectangle
relative to the widgets bounds, when it is meant
to be relative to the widgtets allocation.
While we touch this code, rewrite it to use
gtk_widget_compute_point.
When we don't have a pointing-to rectangle, we want to place
the popover wrt to the parents bounds. But if we have a
pointing-to rectangle, it is relative to the widgets allocation,
which is different from the bounds.
We were not handling the second case correctly, leading to context
menus in the text view being mispositioned by the widgets CSS padding.
While we are touching this code, rewrite it to handle transforms.
Fixes: #5695
Since we are making GdkGLContext call the core wgl*() functions directly
instead of via libepoxy, drop the workarounds that we needed for notifying
libepoxy that wglMakeCurrent() outside of GDK/GTK was called.
This way, we clean up the code, and as a result, we can use the GstGL
APIs like the other platforms to query what GL api that is to be used.
For ensuring that things work between different threads, we now call
gdk_gl_context_clear_current() in place of calling wglMakeCurrent(xxx,
NULL), so that we make sure that there is no current GL context on a
thread outside of GstGL's thread, which Windows does not like.
We might be dealing with GL contexts from different threads, which have more
gotchas when we are using libepoxy, so in case the function pointers for
these are invalidated by wglMakeCurrent() calls outside of GTK/GDK, such as
in GstGL, we want to use these functions that are directly linked to
opengl32.dll provided by the system/ICD, by linking to opengl32.lib.
This will ensure that we will indeed call the "correct" wgl* functions that
we need.
This should help fix issue #5685.
When the GL texture already has a mipmap, we don't
have to download and reupload it to generate one.
We differentiate the handling for texture scale nodes,
where we do want to force the mipmap creation even if
it requires us to reupload the GL texture, and plain
texture nodes, where we just take advantage of a
preexisting mipmap to allow trilinear filtering for
downscaling, or create one if we have to upload the
texture anyway.
Make GdkGLTexture determine if the texture has
a mipmap, and provide private API to query this
information.
This check is done in gdkgltexture.c instead of
gskgldriver.c, since we're already binding the
texture here for other reasons, so it is easy
to query a few more things.
- grab_focus() on a row (happens with scroll_to()) keeps the focus
column intact if possible.
- <Tab> and <Shift-Tab> move through the cells in order, and move
to the next row when at the end.
- <Up> an <Down> move to the next/prev row, keeping the same column
focused.
- <Left> and <Right> move to the prev/next cell, if one is available.
If not, they stay where they are.
Make it move focus just like GtkWindow would.
Otherwise the listview will (try to) handle it and move focus between
cells - which doesn't do anything for lists and only works with grids.
This is a split of GtkListItemWidget into the generic parts of factory
using widgets.
On top of it there's GtkListItemWidget, which takes care of GtkListItem.
They're not used outside of GtkListBase, so no use to have them in the
header.
Requires moving one function up in the source now that the forward
declaration is missing.
create_at_context was confused - it stored a reference
to the newly created context in priv->context, but then
also returned a reference, and the caller stored that
in priv->context again.
Change it to only return a reference.
Fixes: #5690
Store texture coordinates for each slice
instead of assuming 0,0,1,1, and generate
overlapping slices to allow for proper mipmaps.
This almost fixes trilinear filtering with
sliced textures.
This one exhaustively tests reusing the same model as a child model for
many nodes.
This tracks that multiple items-changed signals emitted at the same time
(or multiple handlers for one such signal) doesn't put the treelistmodel
in an inconsistent state while it is handling all of them.
I'm not sure this (ab)use of treelistmodel should be officially
supported, but it works today, so let's test it to see if we can keep it
working.
If there is no other widget in the group that we can focus, don't focus
and activate ourselves.
Otherwise the arrow keys on checkbuttons toggle the checkbutton.
If a GtkImage is using an icon we use a gtk-icon-filter to se the icon
opacity when in insensitive state, however when using other kinds of
pictures we do not apply the same style leading to an inconsistent
result.

Items should be cleared when the node is discarded, not when the node's
children are discarded - which can also happen when a node is collapsed.
Fixes an error introduced in 9048e391b6Fixes#5681
In constrast to our other tests, these use
textures that are big enough to force slicing
with setting GSK_MAX_TEXTURE_SIZE, which we
will use in the following commits to improve
test coverage.
It is useless to have node files with references
to external files in the testsuite, so turn such
textures into data urls by doing a serialization
roundtrip.
No user knows that we have an internal function called
gtk_tree_list_row_destroy() that gets called when a row gets removed
from the treelistmodel.
So everyone was probably just making stuff up about what "destroy"
means.
Related: #5646
That way, we can return the item even after the row is removed. This is
particularly relevant in ListItemFactory::unbind callbacks because they
often use gtk_tree_list_row_get_item() and user code never tracks
changes to this property.
A side effect of this is that the item will survive until the row gets
destroyed, but that's what users expect anyway, so we can live with it.
Related: #5646
This is a good idea to avoid reentrancy problems when any child model
(or potentially more than one child model) has started emitting
items-changed but the emission hasn't arrived in this model yet.
At tat point, we'd get_item() the wrong item from those models.
We want to avoid such cases of reentrancy.
Related: #5646
We cheat and just set the texture parameters instead and hope nothing
explodes.
So far it didn't.
This is only needed to support GLES 2.0 so it's quite a limited set of
hardware these days.
Instead of uploading a texture once per filter, ensure textures are
uploaded as little as possible and use samplers instead to switch
different filters.
Sometimes we have to reupload a texture unfortunately, when it is an
external one and we want to create mipmaps.
When filtering changes for an already-cached
texture, we need to clear the render data
before setting the new one, otherwise it
does not take and we end up reuploading
the texture every frame.
Code above ensures that i is always in [0, n_columns - 1] range, so
the condition was always true, which resulted in filler tile always
being added to the grid. As the result, an empty row appeared at the
end of the grid if the number of columns divided the number of items.
Only add filler tile if last row is not full, i.e. when i > 0.

The GtkUriLauncher calls into the openuri portal, which distinguishes
between files, directories, and URI. The GtkFileLauncher contains logic
to deal with this, because it can already handle the file and folder
differences.
If we have a file:// URI it's easier to create a GFile out of it, and
use the GtkFileLauncher API, while leaving the GtkUriLauncher API for
every other URI scheme.
Same fix as de3c1d0c73, for GtkLabel.

Otherwise GL surfaces that redraw without changing the hotspot have it
applied on top every frame and quickly slide away.
The cairo path and the X11 backend do not have this bug.
The GL Wayland drag surface code path has a bug where it does not reset
the hotspot, so if a GL-backed draw surface redraws without resizing or
resetting the hotspot, it moves away. The next commit will fix that, but
this commit adds a test for that.
Allow to set max texture size using the
GSK_MAX_TEXTURE_SIZE environment variable.
We only allow to lower the max (for obvious
reasons), and we don't allow values smaller
than 512 (since our atlases use that size).
GdkDragSurface-backed widgets are not parented to an existing widget,
unlike popovers, and like toplevels. This means that there's nobody to
actively call gdk_drag_surface_present() to update the size, and
GdkDragSurface should do it on its own, just like GdkToplevel.
This commit implements this for the Wayland backend.
Compute our size when requested by the backend. This makes GtkDragIcons
actually recompute their size when it changes, instead of getting stuck
with the first size and potentially underallocating.
Similarly to GdkToplevel, GdkDragSurface's compute-size should be called
by backends to query the current surface size, and should be connected
to by widget implementations (like GtkDragIcon) to report the current
size.

This allows dropping or copy/pasting rendernodes into apps that accept
SVGs.
Not sure how useful this is because we advertise text/plain from
rendernodes already and we prefer that.
Doing it on hide() is not enough, since in some edge cases we didn't
ever actually map, we just attempted to compute the size, e.g. in
response to a ConfigureNotify event, then the window was destroyed.

... and make the tile finding code use distance.
This also changes how gtk_list_item_manager_get_tile_at() finds the
right tile, so this is a custom commit for bisectability.
gtk_list_item_manager_get_nearest_tile() isn't used yet.
This way, listview and gridview don't need to check if the rect is out
of bounds and nothing is selected, a quick rectangle_intersect() does
the job for them.
Just get the position right and give them a height of 0px, that should
be good enough.
If we don't do that, code will think the item doesn't exist, which is
not what we want.
If the `GtkRecentInfo` represents a directory, simply use it, and
do not try to find its parent in `_gtk_file_chooser_extract_recent_folders()`.
For example, there is an entry in my recently-used database
from the Amberol music player about the folder I have opened
with it, but the folder is not listed on the "Recent" tab of
the file chooser widget, only its parent. After this change,
the directory itself is shown.
Native widgets get allocated via their surface,
so can skip them here. This avoids criticals when
re-mapping a popover for the second time, as can
be seen e.g. in the 'Selections' demo in gtk4-demo.
allocate() should not be calling into ensure_allocate(), they do a similar job.
In the end, the code does the same work, but it should be easier to follow now.
Currently the GtkSearchEngine is torn down every time the search
is stopped, which also means between typed characters. This
prevents any of the optimizations that the GtkSearchEngine can
do in the long run.
Let the GtkSearchEngine stay around for longer, and only be
disposed after search is cancelled, the filechooser moves
onto a different mode than search, or is otherwise unmapped/disposed.
While at it, remove an unused struct field.
Again on massive filesystems, the very first character
is likely to bring a likewise massive amount of search
results that we need to maybe query info for, then create
icons and widgets for. While it's impressive we can do
that, it's also expensive and likely pointless, for the
first character.
Typing a second character is however very likely to
considerably reduce the amount of items to categorize and
show. So start actually searching from there.
Testing on a filesystem with 1434099 files indexed, trying 5
semi-random 1 character searches (n, h, t, i, o) returns on
average 168K items (min. 78771, max. 331471), trying 5
semi-random 2 character searches (no, he, th, in, on)
returns on average 34K items (min. 11133, max. 94961),
which is a more approachable set.
Doing this is enough that typing on a filechooser search
entry feels completely fluid.
The search provider should make it sure there are some
specific GFileInfo fields set. Fix the mimetype extraction
from the query, and use that to fill in the missing gaps
the best we can.
When starting a search over a very populated filesystem, it
is possible that typing the first chars will return a too
high number of results. Even though iterating through the
cursor is in itself very fast, extracting the GIO information
from those many files at once is not going to be as fast.
In order to increase interactivity (i.e. not make things
possibly sluggish) iterate the cursor in an idle function
and add search results to the filechooser model little by little.
If the user keeps typing (as it is likely will happen), there
will be better chances to cancel and proceed to the next
query timely. If not, the results will be there soon enough.
This state is used for visited link-like widgets.
It has no ARIA equivalent, e. g. can not be set programmatically, but it
exists in the browser environment as well.

As fancy as property paths are, recursive resolution of files
to a location increases the big O complexity enough that it's
not a great option on large homedirs with many indexed files.
Ensure the files are from the right location through a URI
prefix match, which does hits an index. This may dramatically
improve performance on large indexed trees.
Testing this query in an isolated testcase with a total
1434099 indexed files shows that it can run more than 1500 times
per second in this computer (an average of 15200 queries in
several 10 second runs), which presumably is a tad faster than
anyone can type.

In certain scenarios, address the issue where gnome.compile_resources

This is the same way as GtkDropDown works. This also unbreaks
GtkComboBox after the recent allocation fix in
75a417e337.
Incidentally, this also makes GtkComboBox actually resize its popup as
intended (that was broken before).
I don't think this is ultimately the final fix, sometimes I still get
allocation warnings. But the proper fix will probably involve changing
some more allocation machinery around popovers. This is good enough for
now.
All the other signal handlers are connected in

The current definitions of the g_io_module_*() symbols do not build on
Visual Studio when building against GLib earlier than 2.75.0 due to the
way how these symbols are decorated in the GLib headers, as Visual Studio
does not allow symbols that were previously marked with 'extern' (or so)
to be marked with anything that is symantically different later.
As a result, if we are using Visual Studio and glib-2.74.x or earlier,
override _GLIB_EXTERN as appropriate in the modules/media sources before
including the GIO headers. This sadly, means that we need a
configure-time check as it would have been too late if we checked the
GLib version using G_VERSION_CHECK macro, as the GIO headers would have
been included already.
There are similar items in the print backends, but we will not attempt
to update these files as they are not meant to be built for Windows.
In derivable classes, the widget's class can be different from the one
dispose_template() was called for, which can lead to failing the
template != NULL check at best, undefined behavior at worst.
Since we already pass the correct GType into the function, just use that
instead.
The problem here is that new windows appear in the list before the
window's dispay gets set and we don't update the filter when the
display changes (would need watches support for the filtermodel).
So add this somewhat hacky method.

Don't misinform the observing listmodel that CSS nodes were removed that
weren't actually removed, but just moved. Otherwise the observer would
think it has run out of items when it really hasn't.
That stupid space in the bottom right when n_items isn't a multiple of
n_columns needs its own tile, or we'll get errors about not finding a
tile.
So make one.
Otherwise, when removing the columns, each column will trigger a
sorter::changed signal emission.
And because sorters are often still connected to a sortlistmodel, we
can't skip that emission and need to do it.
But we only need to do it once.
The previous check does not longer work.
When a model gets all items deleted, there will still be existing tiles
until the next time garbage collection is run.
So do that before checking if the list is empty.
Instead of making it 2 vfuncs for getting horizontal and vertical area,
make it one vfunc to get the area.
Also rewrite the implementations to use the tile's area instead of
trying to deduce things with fancy math.
Instead of randomly changing tiles, the listitemmanager gains a split
vfunc that listview and gridview implement so they can keep their tile
areas intact. The listitemmanager will now conform to these rules:
1. Never delete a tile.
This ensures that all areas stay intact.
2. Never change the n_items of a tile other than setting them to 0.
This causes "empty" areas to appear, but listview/gridview can
easily check for them by checking for tile->n_items == 0.
gtk_list_tile_gc() will get rid of them.
3. Adding items always creates new tiles that are added with empty area.
That way they don't interrupt any existing machinery until the next
allocation.
4. Adding/removing widgets has no effect on areas
This is useful in particular when scrolling where new widgets are
moving between tiles. When the manager moves the widgets, it may
split some areas, but will not remove any existing tiles, so the
whole area stays intact and the list can deal with further scroll
events before an allocation.
This improve the situation for #3334
Instead of the custom size property, use the new tile size.
Also introduce the ability to split tiles, so that gridview can split a
layout that would look like (question mark denoting cells without a
widget, which in this case would be a single tile)
█ █ █ ? ?
? ? ? ? ?
? ? ? ? ?
? ? ?
into 3 rectangular tiles like so:
█ █ █ A A
B B B B B
B B B B B
C C C
This of course also means we need to be able to merge those tiles again
when cells got added/deleted or the gridview was resized. For that job,
gtk_list_tile_gc() exists now, which removes tiles without items and
merges adjacent tiles without widgets.
... and use it to handle ListView allocations.
Nothing spectacular, just proof of concept.
The code introduces the idea that every tile stores its area (others
would call it "allocation", but I avoided that because tiles aren't
widgets). This should allow moving lots of code into gtklistbase.c and
not require special handling inside ListView and GridView.
And that in turn hopefully makes it easier to add more features (like
sections and so on.)
* Instead of using a gpointer to refer to it, use the GtkListTile type.
* Use gtk_list_tile_get_foo() instead of
gtk_list_item_manager_get_tile_foo() naming.
GLib 2.75 started checking if a GFileInfo was created with the attribute
we're querying, instead of failing silently and leaving us in an
inconsistent state.
Turns out that GtkFileChooserWidget, GtkFileSystemModel, and GtkPathBar
trip the newly introduced check.
The GL renderer was creating sripes for nodes that were scaled in
particular ways, probably due to rounding errors.
This testsuite focuses on one of those stripes to make sure they are
gone.
This test fails if we naively create fullscale
intermediate offscreens. This was fixed in the
previous commits.
This tests the fixes in 22ba6b1f33 (for
cairo) and 3a0152b65f (for GL).
Use the same approach and only create an offscreen
that is big enough for the clipped part of the scaled
texture.
If the clipped part is still too large for a single
texture, we give up and just render the texture without
filters (using the regular texture rendering code path
which supports slicing).
The following commit will add the texture-scale-magnify-10000x
test which fails without this fix.
Scale nodes can use large scale factors and we don't want to create
insanely huge Cairo surfaces.
A subsequent commit will add the texture-scale-magnify-10000x
test which fails without this fix.
Cairo surfaces are created transparent.
And even if they weren't, overdrawing with transparency wouldn't erase
what's in the surface because it's a no-op.
It would require CAIRO_OPERATOR_CLEAR or CAIRO_OPERATOR_SOURCE.
GtkAccessible implementations in C can get away returning objects just
by shuffling pointers around, but higher level languages prefer using
full ownership transfer in virtual functions.
Fixes: #5615
This reverts commit 40d4441fd8.
The accessible parent of the child widget in a GtkStackPage is cleared
when the GtkATContext gets disposed, so we don't need to unset it
ourselves. This also avoids a temporary vivification of the GtkATContext
during dispose.
If the early return path in `emit_property_changed()` is taken, and
`value` is floating, it will be leaked. Fix that by sinking `value` on
entry to the function.

When the folder changes, do not select the first item in the list,
so if the user enters a folder and then clicks the accept button,
the current folder is returned instead of the selected one.
To maintain consistency with the previous implementation, when a
folder in the path bar is clicked the previously-entered folder is
selected, and when the file chooser is in open file mode the first
item is always selected.
See #5438
This particular relation was not exposed to at-spi2.
Exposing it required adding a missing at-spi2 relation variant, but it was introduced
in at-spi2-core 2.26, so that's likely safe as well.
It was, for some reason, mapped to ATSPI_ROLE_SECTION, and GTK_ACCESSIBLE_ROLE_SECTION was mapped to
ATSPI_ROLE_FILLER, so the mapping is reversed. So, reverse it and make it correct.
Setting this attribute after querying, but before receiving the
results, can lead to inappropriate behaviour. This can be reproduced
by dragging the scrollbar very quickly in a large directory; after
going up and down a few times, some thumbnails will be wrong.
Without this branch, "wrong" means they'll show the completely wrong
icon or thumbnail, e.g. a folder icon in a video file. With previous
commit, "wrong" means they'll be empty even when there is a thumbnail
available.
The sequence of events that triggers this is as follows:
1. GtkListItem receives a GFileInfo object and passes it to
GtkFileThumbnail via expressions
2. `get_thumbnail()` is called, doesn't find a thumbnail
3. `filechooser::queried` is not set yet, so it is set to TRUE
and we call `g_file_query_info_async()`
4. **Before `thumbnail_queried_cb` is called**, a new GFileInfo
is set, and we cancel the query initiated in the previous
step
5. We now have a GFileInfo with `filechooser::queried` set to
TRUE, and no thumbnail!
This commit fixes that by only setting the `filechooser::queried`
attribute after the icon is queried. We need to set it in two
situations: when the query is successful, or when the error is
not G_IO_ERROR_CANCELLED. That's because the query was cancelled,
we didn't really perform it!
Unset the image if we fail to find the appropriate icon, regardless
of the reason of the failure. Prevents the thumbnail to misrepresent
the GFileInfo it's supposed to represent.
Currently nested custom tags work only as long as the element names differ
from the root one. If it's same, for example:
<condition type="any">
<condition type="max-width">600</condition>
<condition type="max-height">600</condition>
</condition>
then it will fail. Meanwhile the same tags wrapped into <conditions> would
work.
The problem is that custom tag parsing is considered finished as soon as we
encounter a closing tag with the same element name. So instead, track the
nesting level.
Reset alloc_needed_on_child *before* allocating the children. This is
because some child's size_allocate() may call queue_allocate(), which
will bubble up alloc_needed_on_child. An example of this happening is
with GtkScrollable implementations, which are supposed to configure
their adjustments in size_allocate(), which will cause GtkScrollbar's
GtkRange to notice and queue_allocate() on itself.
If we reset alloc_needed_on_child after this happens, then our children
will have a lingering alloc_needed_on_child and will not receive an
allocation.
This commit fixes widgets occasionally losing an allocation when this
scenario happens.
Programmatic changes to the entry contents should
not become part of the undo history.
Sadly, the editable implementations are also used
in the code paths that we use for user-initiated changes,
so we have to be careful to only set them as
irreversible if we are not already in a user action.
Fixes: #5622
Keep a separate boolean for enable-undo, and
disable the history if it is false, or the entry
is not using visible text, or isn't editable.

Previously, it was mapped to ATSPI_STATE_INVALID. However, that state
is used for some internal errors, and not user errors, so use the correct
one for that purpose.
GtkButton still has some code checking if the instance passed to
gtk_button_set_label() is a GtkCheckButton; GtkCheckButton is not a
GtkButton any more.
In 32247bc50e node_get_for_file() was
changed to return GTK_INVALID_LIST_POSITION rather than 0 when the file
is untracked. Most call sites were updated accordingly, but this one was
missed.
Fixes#5619
Up until now, toggle buttons were presented as regular push buttons.
That's the approach used by the ARIA specification, however, our platform
accessibility backend, at-spi2, can not represent accessibe states with values,
so we can not represent the design pattern precisely enough for screen readers.
If, in future, the a11y backends gain this capability, we might consider again
removing this role.
Each node has its own `<node-name>` and supports a custom set of properties, each with their own `<property-name>` and syntax. The following paragraphs document each of the nodes and their properties.
Each node has its own `<node-type>` and supports a custom set of properties, each with their own `<property-name>` and syntax. The following paragraphs document each of the nodes and their properties.
When serializing and the value of a property equals the default value, this value will not be serialized. Serialization aims to produce an output as small as possible.
To embed newlines in strings, use \A. To break a long string into multiple lines, escape the newline with a \.
# Names
### Nodes
Nodes can be given a name by adding a string after the `<node-type>` in their definition. That same node can then be used further down in the document by specifying just the name identifying the node.
### Textures
Just like nodes, textures can be referenced by name. When definining the named texture, the name has to be placed in front of the URL.
