Add a menu-name property and use it in a default implementation
of ::clicked to switch menus if we are inside a stack. This means
GtkModelButton is no longer entirely generic, but rather expects
to be used inside a GtkPopoverMenu. It still works in other contexts
too, of course.
Rename the "toggled" property to "active", since that is what
GtkActionHelper expects to update for check and radio actions.
Also make the property readable, since GtkActionHelper wants
to read it.
Failure to do so results in custom styling leaking through in
the inspector. This is pretty obvious, now that the inspector
is using a separate display connection and is generally isolated
from style changes.
In various places, the broadway backend was just using
the default display and assumed that it is the broadway
display. That may not be the case in a multi-backend world,
so instead iterate over all displays and use the first
broadway display - still not perfect, but enough to survive
for now.
When the window is on a non-default screen, popover_realize
ended up passing a visual and a parent_window from different
screens into gdk_window_new, which doesn't work. Fix it by
using the visual of the parent window.
GtkStyleContext was not properly handling the style cascade when
setting a screen, causing the inspector global CSS to affect the
inspector window, even though the inspector is using a different
screen now.
This helps isolate the inspector from some of the changes that
it can trigger. To specify a different display, set
GTK_INSPECTOR_DISPLAY to the name of the display to use for
the inspector window. If no display is specified, GTK+ will
use a separate connection to the default display.
When a new screen is set on a window, we unrealize it, to
recreate all the resources. But we don't reset the client_decorated
flag, so realize() doesn't call create_decoration() - which makes
sense, since the decoration already exists. But the side-effect
of create_decoration() is to select the rgba visual, and visuals
are per-screen.
Fix this by looking for the rgba visual in set_screen(), and
replacing it with the rgba visual for the new screen, if necessary.
This special code was added back in the days when computation wasn't
idemptotent. These days it is.
Also, the bypass code path is only used in fallback code that is pretty
much unused.
