TEST_STATE returns TRUE if tristate matches boolean flag.

state is a tristate, flag is a boolean state | flag | result IGNORED | TRUE | TRUE IGNORED | FALSE | TRUE PRESSED | TRUE | TRUE PRESSED | FALSE | FALSE RELEASED | TRUE | FALSE RELEASED | FALSE | TRUE

Typedef Documentation

typedef enum _View2DEventPhase View2DEventPhase

event phase for simple extensions that grab the focus, do something (motion) and are released afterwards

---

Enumeration Type Documentation

enum _View2DEventPhase

event phase for simple extensions that grab the focus, do something (motion) and are released afterwards

Enumerator:

EVENT_START	mouse mask of extension has become true (correct button+key combination)
EVENT_MOTION	Motion while mask is still true.
EVENT_RELEASE	Mask of extension has become false.
EVENT_KEY_PRESSED	Key was pressed.
EVENT_KEY_RELEASED	Key was released.
EVENT_ANY	Event phase is undefined and has to be checked by getEvent() method.
EVENT_MOUSEWHEEL	Mouse wheel was turned.
EVENT_MOUSEOVER_UPDATE	An update was requested because a redraw is about to happen and the extension should show actual values.
