Provided Methods§

Source

fn target(&self) -> Option<Pad>

Get the target pad of self. Unref target pad after usage.

§Returns

the target Pad, can be None if the ghostpad has no target set. Unref target pad after usage.

Source

fn set_target(&self, newtarget: Option<&impl IsA<Pad>>) -> Result<(), BoolError>

Set the new target of the ghostpad self. Any existing target is unlinked and links to the new target are established. if newtarget is None the target will be cleared.
