... to a bunch of functions.
This requires a tiny change to the heuristics for the style cache - we
now cache styles when they have the same style provider as their parent
instead of when they have the default provider - but that change doesn't
have any effect in practice.
The parent refs the child, so gtk_css_node_set_parent() adds/removes a
reference.
We should probably refactor this so that we name the function
parent.add(node) instead of node.set_parent(parent) - makes the
refcounting more clear.
Instead of passing the style declaration, take the node's style
declaration. Add arguments to allow overriding the state for the one
case where this didn't work.
The code is confusing the stylecontext=>node transition, so I'll remove
it.
WIth the recent introduction of the parent style cachen, I'm not sure
it's worth it at all. Some crude benchmarking suggests a slight speedup
when removing the cache.
So no guarantees about adding it back later.
- GtkCssWidgetNode
for style contexts owned by a widget
- GtkCssPathNode
for style contexts using a GtkWidgetPath
- GtkCssTransientNode

The functionality of it is supposed to grow, so better put it in a
custom file early.
This is just a naive split so far, the next patches will split things
further.
This commit adds the GtkTextTag:underline-rgba and :strikethrough-rgba
properties and the necessary plumbing to apply these colors in GtkTextLayout.
With this change, you can alter the color of underlines including those
of type PANGO_UNDERLINE_ERROR.
You might want to alter the underline color to differentiate between
spelling and grammer mistakes. In code editors, it is convenient to
differentiate between errors and warnings.
Note that the GtkTextAppearance struct is public ABI and has no spare
room for new fields, so we are resorting to some tricky packing to store
the colors in the unused pixel field of the fg_color and bg_color structs.
This packing is accomplished by the macros in gtktextattributesprivate.h.

This causes pixman warnings, or worse.

With the 3.0 transition, this code went from just querying the entry's
height request to doing a full size request.
Then it got code to revert the features that a full size request does.
And then it grew code that manually computed the baseline.
Avoid this and just do what happened back in the days: Do a regular
height request.
This changes the semantics of the get_frame_size() vfunc wrt its
behavior towards subclasses overwriting the get_height() vfuncs, but I'm
happy to live with that.
Applications forget to set the follow-state property and then some
themes used a style where normal symbolic icons have the same color as

Rework the way we assign an accessible name to menu buttons,
to make sure we pick up a label, should the button contain
one, and only override the name with "Menu" as a fallback.
This reverts commit 63f59dde3a.
It turns out, the state was not just necessary for style computation,
but also for tracking RTL and LTR. And so it broke the reftests.
gtk_tree_selection_real_modify_range() has a g_return_if_fail() if the
start or end paths passed to it do not correspond to real tree nodes.
However, GtkTreePaths inherently do not have to be valid, so it should
be acceptable to call gtk_tree_selection_select_range() with
non-existent paths. Replace the g_return_if_fail() by a silent return,
and add a unit test.

We need to filter out platform-specific sources from the files that we
use with the introspection scanner.
In this specific case I could have moved the gtkclipboard-quartz.c and
the gtkdnd-quartz.c files out of the $(gtk_base_c_sources) variable, but
doing a filter-out on the variable itself is more resilient in case we
eventually add files and we forget about the result.
Now that this is split in two separate gestures, both must be reset
when the WM grabs the pointer. Also, do on resize drags like on move
drags, and claim the gesture before resetting, so the ownership is
properly transferred across any other widgets.

gtk_entry_set_completion() (and _gtk_entry_completion_connect underneath)
may happen when the entry has no toplevel yet. This window acts as the
"parent" for subsurface windows on wayland, and is indispensable to create
its backing wl_subsurface, so this resulted in non-visible popups there.
Fix this by ensuring transient_for is set before showing the popup.

These vfuncs cannot be NULL: implementations are provided by GtkEntry,
and subclasses should not set them to NULL. Instead of conditionalising
the calls to the vfuncs, assert that they’re set and call them
unconditionally.
This prevents the possibility of a subclass setting the vfunc to NULL
and then a gtk_entry_get_*_size() call returning undefined values in its
out variables.

They are a bit terse, and they should point to the preferred way of
overriding the theme, i.e. using a GtkStyleProvider for your
application, and custom style classes.
When the scrollbars are overlayed, the size requisition of the
scrolled window should not depend on whether the scrollbars are
visible or not. This was not quite the case, because we forgot
one case where scrollbar size was still added to the requisition.
Postpone until the last moment whether the target widget still
potentially uses updates from this sequence, or window dragging
actually applies because all gestures on the target went to denied
state.
This fixes window dragging on empty space in a headerbar that is
contained in a paned (as in e.g. gedit).

GtkPlacesSidebar applies a sorting function on

The object might be destroyed when mid operation, causing crashes as the

Avoid scrolling animation when scrolling to where we want

This is not specified specifically by the attached controllers, so let
the scrolledwindow set the mask, as motion events with no buttons pressed
are interesting to it.
https://bugzilla.gnome.org/show_bug.cgi?id=745344
The gesture is hooked to the capture phase, so it works for buttons in
header bars and whatnot. In order to be friendly to the widget it is
capturing events from, an ugly hack is in place to avoid capturing
events when the target widget has a gesture that would consume motion
events.
This happens on button release, which is more convenient if the gesture
can be consumed by something else (eg. window dragging), and already behaves
correctly wrt cancelled gestures, broken grabs, etc.
This also allows us to unify pointer and keyboard behavior, popping up the
menu widget in a single place.
There are two scenarios. A widget sub-class owns a GtkEventController
and passes itself to it, or a controller owned by something else is
passed a widget.
In the second case, if the widget is destroyed before the controller,
we will have a crash when destructing the controller because we will
be accessing invalid memory. Adding a weak reference on the widget
addresses that problem.
This leads to a crash in the first case. When the widget is getting
destroyed, it will drop the reference to its own controller. The
controller will skip touching the widget because the weak reference
would have turned it to NULL. However, when the widget sub-class chains
up to GtkWidget it will try to free all the controllers in its list.
Unfortunately, all these controllers have already been destroyed. So
we need to guard against this too.

We were trying to start search when the user types anything,
but this is annoying more often than helpful, and interferes

If a scrollbar is not shown (because of policies, or because it isn't
necessary), it doesn't make sense to start fade animations on its window

This was added a few years ago, as a way to have _no_ im context
at all. But it didn't actually work. Make it work, and streamline
the handling of none by moving it all to gtkimmodule.c.
As part of this, add context to the translated names of all

In order to provide a constant mtime between OS build and deploy time,

When loading SVGs from ICON_THEME_DIR_UNTHEMED GtkIconInfos,
such as those created for a GLoadableIcon, the size of the pixbuf to
load is set as a product of icon_info->scale.
But a few lines above, icon_info->scale is set to -1 for
ICON_THEME_DIR_UNTHEMED GtkIconInfos, so we'll end up always passing a
negative size to the GdkPixbuf loader, which is interpreted as the
nominal size of the image file.
Instead load the SVG at the desired scaled size in that case.

Add a way to set a delay factor that can be used
to make the long press more or less sensitive.
Making this a factor instead of exposing the delay
itself preserves the value of the setting as an
overall 'slow down long press' setting.
As Sebastian pointed out, just resetting the initial slider
position was an incomplete fix, because it does not cause the
delta to be recomputed, which is important in this scenario,
because you've likely travelled some distance over the slider
before the long press kicks in.
Instead, explicitly record both the slider position and the
delta.
We record the starting position on button press, but only
start the zoom mode when the long press timeout kicks in.
Depending on circumstances, this can cause a noticable jump.
Avoid this by resetting the recorded starting position after
the long press timeout. Suggested by Sebastian Keller.
While a popover is hiding, the modal grab is already gone and the toggle
button is clickable again, but clicking again at that time will result in
gtk_widget_show() trying to show an already shown widget (although fading
out and hidden soon) and the toggle button activated.
So let the menubutton set the active status only if the menu/popover
widget wasn't already shown, and ensure this doesn't get triggered by
double/triple button press events.
As an implementation detail, the popover hooks the fade out animation
on ::hide. Destroying the popover right away here is not a problem, but
prevents the animation from actually running. ::unmap will be run after
the animation is finished, so destroy the popover there.
These have the same visual effect and timing than the gnome-shell ones.
During the hide animation, the popover has been made to take focus
elsewhere, and refuse to take any pointer/keyboard input until the popover
is shown again.
This has been based on work from Timm Bäder.

gtk_scrolled_window_allocate_scrollbar was calling
gtk_scrolled_window_allocate_child just to get the relative
allocation, overlooking the fact that that function is only
safe to call if the scrolled window _has_ a child. Unfortunately,
gtk_scrolled_window_allocate_scrollbar will sometimes get called
when that is not the case. Since we are really only interested
in the relative allocation, just get that directly. This
fixes a segfault in the style-properties-nth-child reftest.
Also try and clarify a few things about event propagation. Move
input-handling.xml into gtk-doc’s expand_content_files variable so it
automatically links to widget documentation. Add links from
gtk_widget_add_events() and friends to the new documentation.

At the time of creating the indicator window, the scrollbar allocation is
poked and reused as the initial window dimensions. This usually happens
on two circumstances, either initially (so a ::size-allocate is emitted,
relocating the windows in the right places), or post-initialization when
calling set_overlay_scrolling() (so the scrollbars already have a valid
size allocation)
However, if the scrolledwindow is unrealized, and later re-realized again,
the scrollbars will already have a valid allocation, although 0,0 based
due to being contained in the previous indicator window. This comes out
wrong then, and the indicator window is given 0,0 based coordinates too.
Fix this by refactoring the scrollbar allocation code out of size_allocate,
and also use that given size at the time of creating the indicator windows,
this will provide the right widget-relative allocation anytime.
Currently, GtkGLArea will leak GError instances set during the context
creation, if an error is set.
If any error is set post-context creation, it should be displayed even
in the case a GL context exists; for instance, we can use the error
display facility for shader compilation errors.
Make that variable go from 0.0 to 1.0 where 0.0 means inactive (slider
is on the left) and 1.0 means active (slider is on the right).
The math is simpler that way and most importantly the value is
independent of size.
Add a button to allow restricting search to the current
folder (and subdirectories). This makes the search more
useful, and makes the file chooser more similar to
nautilus.
In search, we show files from differnt locations, and it makes
sense to show where they come from. This makes the file chooser
more similar to nautilus, too.
Folders that show up among search results were unexpectedly
returned even for GTK_FILE_CHOOSER_ACTION_OPEN. Change things
around so that we switch to the folder instead, which is the
behavior we had in GTK+ 2.x.

This is necessary to avoid unwanted drag cancel animations,
now that GtkNotebook is careful about cancelling a drag
when the dragged tab disappears unexpectedly.
The existence of OpenGL implementations that do not provide the full
core profile compatibility because of reasons beyond the technical, like
llvmpipe not implementing floating point buffers, makes the existence of
GdkGLProfile and documenting the fact that we use core profiles a bit
harder.
Since we do not have any existing profile except the default, we can
remove the GdkGLProfile and its related API from GDK and GTK+, and sweep
the whole thing under the carpet, while we wait for an extension that
lets us ask for the most compatible profile possible.
https://bugzilla.gnome.org/show_bug.cgi?id=744407
Now that we have a two-stages GL context creation sequence, we can move
the profile to a pre-realize option, like the debug and forward
compatibility bits, or the GL version to use.
gtk_list_box_bind_model() binds a GListModel to a GtkListBox.
This is a first step towards having GListModel support in Gtk. It's not
useful for large models, because GtkListBox always creates all widgets
for all rows.
One of the major requests by OpenGL users has been the ability to
specify settings when creating a GL context, like the version to use
or whether the debug support should be enabled.
We have a couple of requirements in terms of API:
• avoid, if at all possible, the "C arrays of integers with
attribute, value pairs", which are hard to write and hard
to bind in non-C languages.
• allow failing in a recoverable way.
• do not make the GL context creation API a mess of arguments.
Looking at prior art, it seems that a common pattern is to split the
construction phase in two:
• a first phase that creates a GL context wrapper object and
does preliminary checks on the environment.
• a second phase that creates the backend-specific GL object.
We adopted a similar pattern:
• gdk_window_create_gl_context() creates a GdkGLContext
• gdk_gl_context_realize() creates the underlying resources
Calling gdk_gl_context_make_current() also realizes the context, so
simple GL users do not need to care. Advanced users will want to
call gdk_window_create_gl_context(), set up the optional requirements,
and then call gdk_gl_context_realize(). If either of these two steps
fails, it's possible to recover by changing the requirements, or simply
creating a new GdkGLContext instance.
