After the :can-focus change in the previous commit, widgets
need to set suitable focus and grab_focus implementations
to implement the desired focus behavior.
This commit does that for all widgets.
Make widgets can-focus by default, and change the semantics
of can-focus to be recursive . If it is set to FALSE, focus
can not enter the widget or its descendents at all anymore.
This commit temporarily breaks focus behavior of widgets
that did not expect to receive focus.
The only place where this should be set is when making
a widget the focus-widget of a window. We still keep
the property around in readonly form, since there are
a few places where we rely on property notification
for it.
This property doesn't carry any new information compared
to GtkWindow:focus-widget. We still keep the gtk_widget_is_focus
getter, as a convenient shortcut.
Make gtk_window_set_focus call gtk_widget_grab_focus internally.
This means that set_focus can now end up putting the focus on
a child of the passed-in widget, and makes the focus-widget
property work for setting initial focus to (the child of) an
entry in a ui file.
After the header widget was introduced, focus would get
stuck in a loop between actions and tabs.
This could be seen in the notebook on page 3 of
widget-factory.
A toplevel will only ever be transient-for to another toplevel, and only
a toplevel will ever be transient-for, so move the field into the
GdkWaylandToplevel, and make it a pointer to another GdkWaylandToplevel.
We them up there, so that code higher up compared to where they are
defined now can make use of them. Also add a few macros for type
checking and casting.
The third version of xdg-shell introduces support for explicit popup
repositioning. If available, make use of this to implement popup
repositioning.
Note that this does *NOT* include atomic parent-child state
synchronization. For that,
https://gitlab.freedesktop.org/wayland/wayland-protocols/issues/13 will
be needed.
This currently uses my own fork of wayland-protocols which adds meson
support, so that we can use it as a subproject. Eventually when
wayland-protocols' meson support lands upstream, we should change it to
point there.
Silence some meson warnings while at it to make CI happy.
This also bumps the glib requirement, since g_warning_once() is used.
- introduce two new colors: $focus_border_color for focused / outlined elements and $_coloured_focus_border_color for focused / outlined elements with a colored background color, like suggested/destructive buttons or selected elements
- set outline / focus color, offset and style accordingly for all widgets
- adapt entry focus color
Now that the GskRenderNode subclasses are recognised as proper
sub-types, we can annotate the constructors with their type. The C API
remains the same.
The introspection scanner tries to match a type name with a get_type()
function, in order to correctly identify a type as a class.
If the function is not available, we have two choices:
- add some special case inside the introspection scanner, similar to
how GParamSpec subclasses are handled in GObject
- add a simple get_type() function
The latter is the simplest approach, and we don't need to change that
much, since we still register all render nodes at once.
Remove the plug/socket exception, and add exceptions for non-X11
windowing systems.
Additionally, speed up the file generation by avoiding string
concatenation in Python.
Language bindings—especially ones based on introspection—cannot deal
with custom type hiearchies. Luckily for us, GType has a derivable type
with low overhead: GTypeInstance.
By turning GskRenderNode into a GTypeInstance, and creating derived
types for each class of node, we can provide an introspectable API to
our non-C API consumers, with no functional change to the C API itself.
The proper way to do this would be to adapt the tables
to have the right data for the platform. Since 4.0 is
a new start in many ways, lets clean this up.
We don't need all of them, only the ones that contain public API. This
allows us to reduce the chance of a stray symbol getting incorrectly
added to the introspection data.
