我基本上有一堂课:
public class WindowEvent extends Event
{
public static const WARNEVENT:String = "warnEvent";
public static const TASKREQEVENT:String = "taskRequestEvent";
public static const TASKANNOUNCE:String = "taskAnnounce";
public static const WINDOWCHANGE:String = "windowChange";
public static const ILLEGALPOSITION:String = "illegalPosition";
// insert brevity
}
前四个事件运行良好,但我只是添加ILLEGALPOSITION
并尝试了这个:
// inside Window.as
private function checkDimensions():void {
if(!Window._legalBoundaryEnable)
return;
... var pass:Boolean = Window.legalBoundary.containsRect(
455 this.getBounds(stage));
456 if(!pass) {
457 this.dispatchEvent(new WindowEvent(WindowEvent.ILLEGALPOSITION,
... "Illegal Position etc."));
}
}
所以当我点击调度方法时,Flex 向我吐出了这个堆栈:
TypeError:错误 #1034:类型强制失败:无法转换 ¬ flex.utils.ui::WindowEvent@511dce41 到 flash.events.MouseEvent。 在 flash.events::EventDispatcher/dispatchEventFunction() 在 flash.events::EventDispatcher/dispatchEvent() 在 mx.core::UIComponent/dispatchEvent() ¬ [C:\autobuild\~\UIComponent.as:9298] 在 flex.utils.ui::Window/checkDimensions()[C:\Users\~\Window.as:457] 在 flex.utils.ui::Window/stageResized()[C:\Users\~\Window.as:220]
从跟踪中可以看出,是最后一个用户代码行。所以 WTF试图用?Window.as:457
flash.events.EventDispatcher.dispatchEventFunction
MouseEvent
