? （加觸發條件）? 鼠標類的事件通常在

?

mouseenter 或者onmouseleftbuttondown

的基礎上改觸發事件

point pos=mouse.getposition(某個控件)相對某個控件的坐標

?

鍵盤就是keydown上改e.key==key.enter?

? ? ? ? OnMyCustom();

? ? }

? ? ? ? DefaultStyleKeyProperty.OverrideMetadata(typeof(MyCustomControl), new FrameworkPropertyMetadata(typeof(MyCustomControl)));
