If you run weston with the headless backend, you get a Wayland
display with no seat, which is just fine by the protocol.
gdk_display_get_default_seat() returns NULL in this case. Various
widgets assume that we always have a seat with a keyboard and a
pointer, since that is what X guarantees. Make things survive
without that, so we can run the testsuite under a headless
Wayland compositor.
The previous code was unreffing the window twice, which caused problems
during dialog destruction. Move to g_list_store_find instead of
iterating manually.
ref() the window before and unref() after. g_list_store_remove will
actually unref() the window, since the toplevel_list owns its own
reference.

I thought I could get away with just unrealizing the
window, but it turns out that gtk_window_hide() is the
place where we remove grabs when a modal dialog goes
away, so we ended up with stuck grabs.
Don't call gtk_widget_destroy; instead implement
gtk_window_destroy outselves by removing the window
from the toplevel lista and dropping the reference that
GTK holds.
Since GtkWindowHandle and GtkHeaderBar do it now, it can be removed from
GtkWindow, along with GTK_WINDOW_REGION_TITLE which at this point doesn't
differ from GTK_WINDOW_REGION_CONTENT.
Closes https://gitlab.gnome.org/GNOME/gtk/-/issues/2689, since
GtkWindowHandle doesn't do that anymore.
Add private gtk_tooltip_maybe_allocate() function
and use it from GtkWindow and GtkPopover.
This will let us stop using the ::size-allocate signal,
without having to redo all the tooltip management first.
That will happen later.
We want to remove GtkBin and GtkContainer as they don't
provide much useful functionality anymore. This requires
us to move get_request_mode and compute_expand down.
Update the accessible implementation to match, remove
remnants of container implementations in GtkWindow
subclasses, and fix livecycle issues around destroy
vs dispose in GtkAssistant.
After this commit, using gtk_container_add on window
subclasses is not allowed anymore, but adding childing
with <child> in ui files still works.
See #2681
Use window title, or custom title widget if it's set. Remove 'title'
property.
Update demos and tests to set the title on the window instead of
headerbar.
The `element-type` annotation is for GList and GSList only, and turns
out adding support for GListModel in gobject-introspection breaks Vala
and the GIR for GIO.
Instead of using `element-type`, we can use the `attributes` annotation,
which is ignored by code generators based on the GIR data.
This function to revoke implicit grabs may be called with a NULL
device, which means all devices should be revoked. Fix the check
so this actually happens.
Fixes implicit grabs (maybe) being unset in result to a GTK grab.
Update the layout when any of the following properties changes:
* modal
* transient-for
* resizable
* deletable
Stop updating it from GtkWindow, make that function static.
Only turn on visible focus when a key event actually leads
to a change in focus location (ie, 'keynav').
Make the visible focus disappear after 5 seconds of no
keyboard interaction, to avoid permanent focus ring
distraction.
As an extra bonus, make it so that we make the focus
visible while the Alt key is pressed. This gives us
a 'find my focus!' shortcut, and goes well with the
prexisting use of Alt for finding mnemonics.
Discussed in: #2644
Add the following actions:
* window.close
* window.toggle-maximize
* window.minimize
Ensure they are disabled when not appropriate, such as for modal windows.
Use them in GtkHeaderBar.
The application menu isn't particular relevant anymore, and the support for
showing fallback appmenu as a headerbar icon is one of the things tying
GtkWindow to GtkHeaderBar.
Remove support for "menu" window decoration element completely, update
GtkHeaderBar docs.
This was only living in gtkcontainer.c for historic
reasons. Move it closer to where it belongs, and
rename it from 'idle' to 'layout', since it is
really about the layout phase of the frame clock,
nowadays.
GdkEvent has been a "I-can't-believe-this-is-not-OOP" type for ages,
using a union of sub-types. This has always been problematic when it
comes to implementing accessor functions: either you get generic API
that takes a GdkEvent and uses a massive switch() to determine which
event types have the data you're looking for; or you create namespaced
accessors, but break language bindings horribly, as boxed types cannot
have derived types.
The recent conversion of GskRenderNode (which had similar issues) to
GTypeInstance, and the fact that GdkEvent is now a completely opaque
type, provide us with the chance of moving GdkEvent to GTypeInstance,
and have sub-types for GdkEvent.
The change from boxed type to GTypeInstance is pretty small, all things
considered, but ends up cascading to a larger commit, as we still have
backends and code in GTK trying to access GdkEvent structures directly.
Additionally, the naming of the public getter functions requires
renaming all the data structures to conform to the namespace/type-name
pattern.
This is used for widgets that contain the focus widget,
reserving the focused state for the focus location itself.
This aligns our focus state handling with
https://www.w3.org/TR/selectors-4/
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.
We don't get a focus-out on the event controller, when
the surface is losing keyboard focus, since we are not
moving our focus to some other widget, so we are never
unsetting the mnemonics-visible property. Do that in
response to surface state changes instead.
API remains the same, but activation is now done via a
shortcutcontroller.
The code uses a controller with global scope so that the
shortcuts are managed with all the other global shortcuts.
When creating shortcuts, there almost always are a trigger and an action
available for use. So make gtk_shortcut_new() take those as arguments.
Also add gtk_shortcut_new_with_arguments() so people can easily pass
those in, too.
Similar to GtkShortcutTrigger, GtkShortCutAction provides all the
different ways to activate a shortcut.
So far, these different ways are supported:
- do nothing
- Call a user-provided callback
- Call gtk_widget_activate()
- Call gtk_widget_mnemonic_activate()
- Emit an action signal
- Activate an action from the widget's action muxer
This adds an interface for taking care of shortcut controllers with
managed scope.
Only GtkWindow currently implements this interface, so we need to ensure
that we check if any top-level widget we reach is a shortcuts manager
before we call into it.
And use it.
I just added it to GtkWidget just to show that I can.
The real reason I want it is for gamepad/joystick triggers
in games, so that it becomes possible to select 2 different
triggers (gamepad and keyboard) for the same shortcut.
