TitleWindow Subclass for Easily Handling Popups
Typically if you choose to use a TitleWindow, odds are you’re going to add it with the PopupManager and use the Close button. So rather than having to always set that up and add listeners for the CloseEvent, use this extended class PopupBase. It’s used the same as TitleWindow, declared in actionscript
var popup:PopupBase = new PopupBase();
or mxml,
<containers:PopupBase />
but by default it:
- sets showCloseButton=true
- sets a listener for CloseEvent
- removes the popup when Close button is pressed
You can override the onClose handler to add different functionality.
package containers
{
import mx.containers.TitleWindow;
import mx.events.CloseEvent;
import mx.managers.PopUpManager;
public class PopupBase extends TitleWindow
{
public function PopupBase()
{
showCloseButton = true;
addEventListener(CloseEvent.CLOSE, onClose);
}
protected function onClose(event:CloseEvent):void
{
PopUpManager.removePopUp(this);
}
}
}
{
import mx.containers.TitleWindow;
import mx.events.CloseEvent;
import mx.managers.PopUpManager;
public class PopupBase extends TitleWindow
{
public function PopupBase()
{
showCloseButton = true;
addEventListener(CloseEvent.CLOSE, onClose);
}
protected function onClose(event:CloseEvent):void
{
PopUpManager.removePopUp(this);
}
}
}
