clear_drawing_objectT_clear_drawing_objectClearDrawingObjectClearDrawingObjectclear_drawing_object — Löschen eines Zeichenobjekts.
Signatur
clear_drawing_object( : : DrawID : )
Herror T_clear_drawing_object(const Htuple DrawID)
def clear_drawing_object(draw_id: HHandle) -> None
Beschreibung
clear_drawing_objectclear_drawing_objectClearDrawingObjectClearDrawingObjectClearDrawingObjectclear_drawing_object löscht das Zeichenobjekt DrawIDDrawIDDrawIDDrawIDdrawIDdraw_id.
Das Zeichenobjekt wird automatisch von allen Fenster entfernt,
an die es zuvor angehängt wurde. Nach dem Aufruf von clear_drawing_objectclear_drawing_objectClearDrawingObjectClearDrawingObjectClearDrawingObjectclear_drawing_object
kann das Zeichenobjekt nicht weiter verwendet werden.
Ausführungsinformationen
- Multithreading-Typ: reentrant (läuft parallel zu nicht-exklusiven Operatoren).
- Multithreading-Bereich: global (kann von jedem Thread aufgerufen werden).
- Wird ohne Parallelisierung verarbeitet.
Dieser Operator modifiziert den Zustand des folgenden Eingabeparameters:
Während der Ausführung dieses Operators muss der Zugriff auf den Wert dieses Parameters synchronisiert werden, wenn er über mehrere Threads hinweg verwendet wird.
Parameter
DrawIDDrawIDDrawIDDrawIDdrawIDdraw_id (input_control, Zustand wird modifiziert) drawing_object → HDrawingObject, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)
Handle des Zeichenobjekts.
Ergebnis
clear_drawing_objectclear_drawing_objectClearDrawingObjectClearDrawingObjectClearDrawingObjectclear_drawing_object gibt 2 (H_MSG_TRUE) zurück, falls die DrawIDDrawIDDrawIDDrawIDdrawIDdraw_id
gültig ist. Gegebenenfalls wird eine Fehlerbehandlung durchgeführt.
