Question

Here is a functional example:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
    <mx:Script>
        <![CDATA[
            import mx.controls.Alert;
            public function go():void{              
                Alert.show("The focus will return to txtOne. Look: ");
            }
        ]]>
    </mx:Script>
    <mx:VBox>
        <mx:TextInput id="txtOne" text="1" focusOut="go()"/>
        <mx:TextInput id="txtTwo" text="2"/>    
    </mx:VBox>  
</mx:Application>

When you change from txtOne to txtTwo, the Alert is showed and after pressing OK, the focus will return to txtOne. I don’t want that to happen. How to solve this?

Answer 1

Alert.show has close callback argument, so you will know, when it is closed and set focus to something else. Update: you should have flag, indicating, that focus out event can be processed:

private var needAlert:Boolean = true;

public function go():void
{
    if (needAlert)
    {
        Alert.show("The focus will return to txtOne. Look: ",
            "", 0, null, myCloseHandler);
        needAlert = false;
    }
}

private function myCloseHandler(event:CloseEvent):void
{
    this.setFocus();
    needAlert = true;
}
