Window resizing

Question

I have a window skin with gripper. Gripper is use to resize window with to listener mousedown and mouseup.

My problem is when i finish to resize window, I stop to press mouse and if I click anywhere on window, the window is resizing and I don't know why.

The below part of my code:

protected function btResize_mouseDownHandler(event:MouseEvent):void
        {
            stage.addEventListener( MouseEvent.MOUSE_UP, btResize_mouseUpHandler );
            stage.nativeWindow.startResize();
        }

        protected function btResize_mouseOutHandler(event:MouseEvent):void
        {
            stage.removeEventListener( MouseEvent.MOUSE_OUT, btResize_mouseOutHandler );                
        }


        protected function btResize_mouseUpHandler(event:MouseEvent):void
        {
            stage.removeEventListener( MouseEvent.MOUSE_UP, btResize_mouseUpHandler );



        }

<s:Button height="15" id="btResize" width="15"
          bottom="0" right="0"
          skinClass="spark.skins.spark.windowChrome.GripperSkin" 
          mouseDown="btResize_mouseDownHandler(event)"
          mouseUp="btResize_mouseUpHandler(event)"
          buttonMode="true"/>

So, I appreciate, your help.

Thanks

Answer 1

This behavior does not occur for me. I'm using flex SDK 4.6 targeting AIR 3.1. So one option (if possible) is to upgrade your SDK if it is not at 4.6.

The code below works as well. Notice I changed stage to this:

<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009" 
                       xmlns:s="library://ns.adobe.com/flex/spark" 
                       xmlns:mx="library://ns.adobe.com/flex/mx">

    <fx:Script>
        <![CDATA[
            import mx.events.ResizeEvent;
            protected function btResize_mouseDownHandler(event:MouseEvent):void
            {
                this.nativeWindow.startResize();
            }
        ]]>
    </fx:Script>

    <s:Button height="15" id="btResize" width="15"
              bottom="0" right="0"
              skinClass="spark.skins.spark.windowChrome.GripperSkin" 
              mouseDown="btResize_mouseDownHandler(event)"
              buttonMode="true"/>

</s:WindowedApplication>
