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)
If you want to get rounded corners on an hbox, instead of
:first-child {
border-top-left-radius: 5px;
border-bottom-left-radius: 5px;
}
:last-child {
border-top-right-radius: 5px;
border-bottom-right-radius: 5px;
}
you now need to write:
:first-child, :last-child:dir(rtl) {
border-top-left-radius: 5px;
border-bottom-left-radius: 5px;
}
:last-child, :first-child:dir(rtl)
{
border-top-right-radius: 5px;
border-bottom-right-radius: 5px;
}

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.
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
cache and properly invalidate the result of g_type_from_name().
This bumps the glib requirement to 2.35.3 to get the new function.

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
that knows how to translate schemas. Attempting to translate them
causes a build failure, so for now, let's leave them in en_US.

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.
