【问题描述】:
我有一个扩展至 NativeWindow 的类 FlexNativeWindow。 我使用此方法在我的 AIR 应用程序上创建新窗口。 一切正常,但某些键盘交互不可用。
例如焦点围绕文本输入不可见。 向下和向上键在 DropDownList 上不起作用。 TabOrder 不好用!
你能解释一下为什么吗?因为我很失望!
创建新窗口的代码
var wdetcorr:wDetailCorrespondant = new wDetailCorrespondant();
wdetcorr.monIdCorresp = correspDG.selectedItem.crIndex;
var wOptions:NativeWindowInitOptions = new NativeWindowInitOptions();
wOptions.systemChrome = NativeWindowSystemChrome.NONE;
wOptions.transparent = false;
var fnwDetailPatient:FlexNativeWindow = new FlexNativeWindow(wdetcorr, wOptions);
fnwDetailPatient.active();
关于我的自定义 NativeWindow 的代码
package fr.int.ui.windowSkin
{
import flash.display.NativeWindow;
import flash.display.NativeWindowInitOptions;
import flash.events.Event;
import flash.events.KeyboardEvent;
import flash.ui.Keyboard;
import mx.core.IUIComponent;
import mx.core.IVisualElement;
import mx.core.IVisualElementContainer;
import mx.core.UIComponent;
import mx.events.*;
import mx.managers.WindowedSystemManager;
[Event(name="creationComplete", type="mx.events.FlexEvent")]
public class FlexNativeWindow extends NativeWindow implements IFlexNativeWindow
{
private var _systemManager:WindowedSystemManager;
private var _content:UIComponent;
private var _window:IVisualElementContainer;
public function FlexNativeWindow(window:IVisualElementContainer, initOptions:NativeWindowInitOptions = null)
{
super(initOptions);
_window = window;
addEventListener(Event.ACTIVATE, windowActivateHandler);
}
public function addElement(control:IVisualElement):void
{
_window.addElement(control);
}
public function removeElement(control:IVisualElement):void
{
_window.removeElement(control);
}
private function windowActivateHandler(event:Event):void
{
event.preventDefault();
event.stopImmediatePropagation();
removeEventListener(Event.ACTIVATE, windowActivateHandler);
if (stage)
{
if (!_systemManager)
_systemManager = new WindowedSystemManager(IUIComponent(_window));
stage.addChild(_systemManager);
dispatchEvent(new FlexEvent(FlexEvent.CREATION_COMPLETE));
stage.addEventListener(Event.RESIZE, windowResizeHandler);
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDownListener);
}
}
private function keyDownListener (e:KeyboardEvent):void {
if (e.keyCode == Keyboard.ESCAPE) {
stage.nativeWindow.dispatchEvent(new Event("myEventClose", true));
stage.nativeWindow.close();
}
}
private function windowResizeHandler(event:Event):void
{
// prise en compte de la valeur mini
UIComponent(_window).height = stage.stageHeight;
UIComponent(_window).width = stage.stageWidth;
}
}
}
【问题讨论】:
-
添加自己的WindowedSystemManager(并添加到舞台)的目的是什么?我认为这可能会干扰 Flex 创建的那个。
