Field Summary

static DockRelocatorMode	NO_COMBINATION Ensures that a Dockable can be dragged only if no combination results.
static PropertyKey<ModifierMask>	NO_COMBINATION_MASK the modifiers that must be pressed to activate the NO_COMBINATION relocator mode
static PropertyKey<ModifierMask>	SCREEN_MASK the modifiers that must be pressed to activate the SCREEN_ONLY relocator mode
static DockRelocatorMode	SCREEN_ONLY Ensures that a Dockable can be dragged only onto a ScreenDockStation.

Method Summary

void	setActive(DockController controller, boolean active) Tells this mode whether it should have an influence of the behaviour or not.
boolean	shouldBeActive(DockController controller, int modifiers) Tells whether this mode should be activated because of the state of the controller and the last MouseEvent.

Field Detail

SCREEN_MASK

static final PropertyKey<ModifierMask> SCREEN_MASK

the modifiers that must be pressed to activate the SCREEN_ONLY relocator mode

SCREEN_ONLY
