Those property features don't seem to be in use anywhere.
They are redundant since the docs cover the same information
and more. They also created unnecessary translation work.
Closes#4904
Silly optimization to get rid of
gtk_main_do_event
gtk_inspector_handle_event
gtk_inspector_window_get_for_display
g_object_get_data
showing up in profiles even though it's useless since we've never even
created any inspector window in the first place.
When configuring the inspector display, preserve
debug flags that affect which GL variant we pick.
Otherwise, we may end up with a GLX context on the
default display, and an EGL context on the inspector
one. This hopelessly confuses libepoxy, and things
don't go well when that happens.
Ever since we added surface-to-widget transforms,
the autofading of the fps overlay did not work anymore,
since it was given the transient transform node, most
of the time.
Fix this by passing both the root of the node tree and
the node for the toplevel widget to prepare_render, and
hande the widget node to the overlays. Update the
affected overlays that need to have their positioning
adjusted.
Show a tab for accessibility information.
This shows the role and the accessible attributes
(states, properties, relations).
For now, changing the values is not possible, and
we only show the explicitly set values. In the future,
we want to show the attributes that are relevant for
the role, regardless of whether they are set or not,
and allow changing some of the attributes (the ones
that are not fully managed by GTK itself).
We were hiding the inspector when the window
is closed, but that has the side-effect of
keeping references to application windows,
so we would keep them artificially alive,
which can have side-effects.
So, make the inspector go away when closed.
Rename the DataList object to TreeData, in preparation
for adding a ListData object for list models. While
we are touching it, modernize it a bit (drop the Private
struct, use a layout manager, etc).
Get the native transform only once, for all overlays. Unfortunately we
have to undo this for the updates overlay since that one gets values
in surface coordinates.
Don't crash while picking. The event signal broke
when GdkEvent was turned into a type instance,
since the automatic marshallers don't know how to
deal with that. Manually set the right marshaller.
Instead of using a grab on a GtkInvisible, use
a hook in the GTK event propagation machinery to
get events.
The only downside of this approach is that we
lose the crosshair cursor. But we get rid of
the last use of GtkInvisible.
