uimenu PropertiesHandles that are hidden are still valid. If you know an object’s handle, you canset and get its properties, and pass it to any function that operates on handles.Interruptible{on} | offCallback routine interruption mode. If a callback is executing and the usertriggers an event (such as a mouse click) on an object for which a callback isdefined, that callback attempts to interrupt the first callback. MATLABprocesses the callbacks according to these factors:• The Interruptible property of the object whose callback is executing• Whether the executing callback contains drawnow, figure, getframe, pause,or waitfor statements• The BusyAction property of the object whose callback is waiting to executeIf the Interruptible property of the object whose callback is executing is on(the default), the callback can be interrupted. The callback interruptsexecution at the next drawnow, figure, getframe, pause, or waitfor statement,and processes the events in the event queue, which includes the waitingcallback.If the Interruptible property of the object whose callback is executing is off,the callback cannot be interrupted (except by certain callbacks; see the notebelow). The BusyAction property of the object whose callback is waiting toexecute determines what happens to the callback.Note If the interrupting callback is a DeleteFcn or CreateFcn callback or afigure’s CloseRequest or ResizeFcn callback, it interrupts an executingcallback regardless of the value of that object’s Interruptible property. Theinterrupting callback starts execution at the next drawnow, figure, getframe,pause, or waitfor statement. A figure’s WindowButtonDownFcn callbackroutine, or an object’s ButtonDownFcn or Callback routine are processedaccording to the rules described above.LabelstringMenu label. A string specifying the text label on the menu item. You can specifya mnemonic using the “&” character. Whatever character follows the “&” in thestring appears underlined and selects the menu item when you type that2-566
