Flex：stopPropagation ColorPicker的事件Keyboard.ENTER

Question

我有一個WindowedApplication，在keyboardEvent上（在ENTER鍵上）有一個偵聽器，但是當用戶選擇使用colorpicker並鍵入一個十六進制代碼，然後敲擊ENTER事件也支持我的WindowedApplication。 我不得不停止傳播。 任何提示或摘錄？ 感謝 P.

Answer 2

這是TitleWindow，其中Cp是在ColorPicker的代碼的一部分。

...  

public function init（）：void {cp.addEventListener（ColorPickerEvent.ENTER，handler）; }

public function handler（e：ColorPickerEvent）：void { e.stopImmediatePropagation（）; }

public function changeColor（e：ColorPickerEvent）：void { Application.application.couleur = cp.selectedColor; PopUpManager.removePopUp（this）; } ...

這是從我的主MXML：

... employeeList.addEventListener（KeyboardEvent.KEY_UP，enterListener）; ...

私有函數enterListener（E：的KeyboardEvent）：無效{
如果（e.keyCode == Keyboard.ENTER）{
如果（employeeList.selectedItem）{
showDetail（employeeList.selectedItem爲僱員）;
}
}
}
