Class
ClapperGtkBillboard
Description [src]
final class ClapperGtk.Billboard : ClapperGtk.Container
implements Gtk.Accessible, Gtk.Buildable, Gtk.ConstraintTarget {
/* No available fields */
}A layer where various messages can be displayed.
ClapperGtkBillboard widget is meant to be overlaid on top of
ClapperGtkVideo as a normal (non-fading) overlay.
It is used to display various messages/announcements and later takes care of fading them on its own.
If automatic volume/speed change notifications when their values do
change are desired, functions for announcing them can be run in callbacks
to corresponding property notify signals on the ClapperPlayer.
Instance methods
clapper_gtk_billboard_announce_speed
Temporarily displays current speed value on the
side of billboard.
clapper_gtk_billboard_announce_volume
Temporarily displays current volume level on the
side of billboard.
Methods inherited from ClapperGtkContainer (10)
clapper_gtk_container_get_adaptive_height
Get a container adaptive height threshold.
clapper_gtk_container_get_adaptive_width
Get a container adaptive width threshold.
clapper_gtk_container_get_child
Get a child GtkWidget of container.
clapper_gtk_container_get_height_target
Get a container height target.
clapper_gtk_container_get_width_target
Get a container width target.
clapper_gtk_container_set_adaptive_height
Set an adaptive height threshold. When widget is resized to value or lower,
an ClapperGtkContainer::adapt signal will be emitted with TRUE to
notify implementation about mobile adaptation request, otherwise FALSE when
both threshold values are exceeded.
clapper_gtk_container_set_adaptive_width
Set an adaptive width threshold. When widget is resized to value or lower,
an ClapperGtkContainer::adapt signal will be emitted with TRUE to
notify implementation about mobile adaptation request, otherwise FALSE when
both threshold values are exceeded.
clapper_gtk_container_set_child
Set a child GtkWidget of container.
clapper_gtk_container_set_height_target
Same as clapper_gtk_container_set_width_target() but for widget height.
clapper_gtk_container_set_width_target
Set a width that container should target. When set container
will not stretch beyond set width while still expanding into
possible boundaries trying to reach its target.
