Expand description
constraint lifetime
These values represent different lifetime semantics. They are passed as arguments to the factory requests to specify how the constraint lifetimes should be managed.
Variants (Non-exhaustive)
This enum is marked as non-exhaustive
Oneshot
the pointer constraint is defunct once deactivated
A oneshot pointer constraint will never reactivate once it has been deactivated. See the corresponding deactivation event (wp_locked_pointer.unlocked and wp_confined_pointer.unconfined) for details.
Persistent
the pointer constraint may reactivate
A persistent pointer constraint may again reactivate once it has been deactivated. See the corresponding deactivation event (wp_locked_pointer.unlocked and wp_confined_pointer.unconfined) for details.
