Menus traditionally don't have separate
hover and focus locations. Make the same
change here that we already did for
popover menubars: Track the active item
and set its selected state. Both keynav
and mouse change the active item.
This is expected menu keynav behavior: If the
focused item has a submenu, open it on right
arrow press. And if we are in a submenu title,
make left arrow press close it.
We only want to reserve indicator size if
there are any checks or radios in the popover.
Unfortunately, GtkIcon has a hardcoded min-size
of 16, defeating this use. Work around by
wrapping each indicator in a box, and showing/
hiding the actual indicator.
When we are not given an explicit accel (as is
the case when the popover is constructed from
a model), then look it up from the GtkApplication
at map time.
Move checks to the left, and introduce a size group
to align things. The size group is provided by the
parent, using the new ::indicator-size-group property.
This gets us out of using direct presentational
markup like 'inverted' and 'centered' and will
make it easier to play with different layout.
Use the new role when creating popover
menus from models.
Previously, GtkBin was only snapshot'ing its one and only child, but
nowadays it doesn't implement snapshot at all and the default
implementation in GtkWidget just snapshots all child widgets, which is
exactly what the implementation in gtkmodelbutton.c was doing.
Binds this property to the button's label, allowing a model button to
have text with markup.
This will be convenient for buttons like 'Online Accounts <sup>↗</sup>'.
Remove all the old 2.x and 3.x version annotations.
GTK+ 4 is a new start, and from the perspective of a
GTK+ 4 developer all these APIs have been around since
the beginning.
Instead, add a function gtk_image_set_icon_size() for the cases where
overriding the icon size is necessary.
Treat icon sizes the same way as pixel sizes, too. So gtk_image_clear()
no longer unsets the icon size.
Instead of returning the icon size with them, make
gtk_image_get_icon_name() and gtk_image_get_gicon() only return the icon
itself.
As a benefit, we can turn them into regular getters that return values
instead of requiring out parameters.
Instead, provide gtk_image_get_icon_size() to query the icon size.
Since setting a clip is mandatory for almost all widgets, we can as well
change the size-allocate signature to include a out_clip parameter, just
like GtkCssGadget did. And since we now always propagate baselines, we
might as well pass that one on to size-allocate.
This way we can also make sure to transform the clip returned from
size-allocate to parent-coordinates, i.e. the same coordinate space
priv->allocation is in.
The event shall no longer be "directed" to the event window, but the
widget. Getting a enter/leave event is enough now to know whether the
pointer is inside or outside the widget.
Add a new ::measure vfunc similar to GtkCssGadget's that widget
implementations have to override instead of the old get_preferred_width,
get_preferred_height, get_preferred_width_for_height,
get_preferred_height_for_width and
get_preferred_height_and_baseline_for_width.
Always have Since: annotations at the very bottom, use the correct
ClassName::signal-name/ClassName:property-name syntax, fix a few typos
in type names, wrong function names, non-existing type names, etc.
