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
with the location entry. So, stick with explicitly enabled
search (via the search button or Alt-S) for now.
Although gtk_list_box_row_grab_focus() is not a public function
it can be easily called by gtk_widget_grab_focus() with a row argument
which has been removed from the list box and has box == NULL.

The height of the text buttons depends on the font height,
whereas the search button has a fixed-size icon in it...
Prevent unevent heights by putting them all in a size group.

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
on captured motion events.
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
im modules we ship.
In order to provide a constant mtime between OS build and deploy time,
while also maintaining a hardlink content-addressed model independent of
timestamps, ostree sets all mtimes to 0.
The icon cache code currently ignores directories with mtime 0, assuming
they don't exist.
Track directory existence in a more precise way.

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.
This fixes blurry icon in the notification panel in gnome-shell.

When loading a GResource-backed GFileIcon into a GtkIconInfo we
currently fail to populate the is_resource private field.
Also, since is_svg is set by looking at the filename, and
g_file_get_path() returns NULL for a GResourceFile, is_svg was always
FALSE.

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.
