NAME
Clutter::Stage - Top level visual element to which actors are placedSYNOPSIS
my $stage = Clutter::Stage->new(); $stage->signal_connect(destroy => sub { Clutter->main_quit }); $stage->add($actor, $rectangle, $group, $texture, $label); $stage->show(); $stage->destroy(); # the default stage is owned by Clutter, and get_default() will # always return the same pointer my $stage = Clutter::Stage->get_default();
DESCRIPTION
Clutter::Stage is a top level 'window' on which child actors are placed and manipulated.Clutter creates a default stage upon initialization, which can be retrieved using Clutter::Stage::get_default(). Clutter always provides the default stage, unless the backend is unable to create one. The stage returned by Clutter::Stage::get_default() is guaranteed to always be the same.
Backends might provide support for multiple stages. The support for this feature can be checked at run-time using the Clutter::feature_available() function and the 'stage-multiple' flag. If the backend used supports multiple stages, new Clutter::Stage instances can be created using Clutter::Stage::new(). These stages must be managed by the developer using Clutter::Actor::destroy(), which will take care of destroying all the actors contained inside them.
Clutter::Stage is a proxy actor, wrapping the backend-specific implementation of the windowing system. It is possible to subclass Clutter::Stage, as long as every overridden virtual function chains up to the parent class corresponding function.
