从不同的mxml组件中的TitleWindow调用Application.application.enable [英] Calling Application.application.enable from a TitleWindow in a different mxml component

问题描述

我有一个Flex RIA应用程序，在应用程序标签中有一个按钮，当它从另一个.mxml文件中按下一个TitleWindow时，并设置

  application.enable = false 
  

这样用户不能使用应用程序中的任何组件，并且仍然可以使用TitleWindow中的组件。

问题其实。当TitleWindow关闭的时候，我想让他把应用程序还原到

  application.enable = true 
  

重新启用应用程序。但是我不能从TitleWindow.mxml中调用这段代码。

我怎样才能做到这点？

<？xml version =1.0encoding =utf-8？>
< mx：Style source =theme / simplicitygray.css/>

< mx：Script>
<！[CDATA [
import mx.managers.PopUpManager;
private var clientid = 0;

public function openWindow（）：void
{
if（clientid == 0）
{
PopUpManager.createPopUp（this，Login，false） ;
application.enabled = false;
} else {
PopUpManager.createPopUp（this，Conta，false）;
application.enabled = false;
}
}
]]>
< / mx：Script>

< mx：Panel x =10y =40width =565height =400layout =absolute>
< / mx：面板>
< mx：Button x =508y =10label =Acederclick =openWindow（）;/>

< / mx：应用程序>


还有一个标题窗口。一旦他们是相同的。
$ b Login.mxml

 <？xml version =1.0encoding =utf-8？> 
  
< mx：Script> 
<！[CDATA [
 import mx.managers.PopUpManager; 
 public function centerWindow（）：void 
 {
 PopUpManager.centerPopUp（this）; 
 
 
 public function closeWindow（）：void 
 {
 PopUpManager.removePopUp（this）; 
 
} 
 
]]> 
 
< / mx：Script> 
 
< / mx：TitleWindow> 
  

任何帮助都非常好。感谢。

解决方案 应用程序是 $ c $> b


$ b> public function closeWindow（）：void
{
PopUpManager.removePopUp（this）;
Application.application.enabled = true;





另外还有一个更简单的方法来实现以下功能：

这样用户就不能使用应用程序中的任何组件，而仍然可以使用TitleWindow中的组件。

即使用模式弹出窗口。将 createPopUp 的第三个参数设置为 true 就是这样 - 您不必启用/禁用应用程序手动：flex会照顾它。

  PopUpManager.createPopUp（this，Login，true）; 
  

一旦您调用 removePopUp 。

Good day.

I have a Flex RIA App, and in the application tag there is a button when its pressed calls upon a TitleWindow from another .mxml file, and sets

application.enable = false

That way the user cant use any of the components in the application, and still can use the components in the TitleWindow.

The problem its. When the TitleWindow is close i want him to restore the application back to

application.enable = true

Wich enables the application once again. But i can't call that code from inside the TitleWindow .mxml

How can i do it?..

Here is the Source:

Loja.mxml

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="585" height="450" xmlns:ns1="com.*">
<mx:Style source="theme/simplicitygray.css" />

    <mx:Script>
        <![CDATA[
            import mx.managers.PopUpManager;
            private var clientid = 0;       

            public function openWindow() : void
            {
                if (clientid == 0) 
                {
                    PopUpManager.createPopUp(this,Login,false);
                    application.enabled = false;
                } else {
                    PopUpManager.createPopUp(this,Conta,false);
                    application.enabled = false;
                }
            }
        ]]>
    </mx:Script>

    <mx:Panel x="10" y="40" width="565" height="400" layout="absolute">
    </mx:Panel>
    <mx:MenuBar x="10" y="10" width="565" height="22"></mx:MenuBar>
    <mx:Button x="508" y="10" label="Aceder" click="openWindow();"/>

</mx:Application>

And one of the title windows. Once they are the same.

Login.mxml

<?xml version="1.0" encoding="utf-8"?>
<mx:TitleWindow xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="350" height="200" creationComplete="centerWindow()" showCloseButton="true" close="closeWindow()" title="Login">

    <mx:Script>
        <![CDATA[
            import mx.managers.PopUpManager;
            public function centerWindow():void
            {
                PopUpManager.centerPopUp(this);
            }

            public function closeWindow():void
            {
                PopUpManager.removePopUp(this);

            }

       ]]>

    </mx:Script>

</mx:TitleWindow>

Any help is greattly apreciated. Thanks.

解决方案

application is a static property of the Application class and can be called from the TitleWindow

public function closeWindow():void
{
    PopUpManager.removePopUp(this);
    Application.application.enabled = true;
}

BTW, There is another easier way to achieve the following:

That way the user cant use any of the components in the application, and still can use the components in the TitleWindow.

That is to use a modal popup. Set the third parameter of the createPopUp to true and that's it - you don't have to enable/disable the application manually: flex will take care of it.

PopUpManager.createPopUp(this,Login, true);

application will automatically become functional once you call removePopUp.
