    Auto-resize a panel


      I have a panel holding a variety of content. As content is added or removed, I would like the panel to resize itself to fit, rather than adding vertical scrollbars. Does anyone know a way of accomplishing this?

          If the Panel does not have a specified width and height, it will resize automatically. A sample:

          <?xml version="1.0" encoding="utf-8"?>
          <mx:Application xmlns:mx=" http://www.adobe.com/2006/mxml" >
          <mx:Button label="Add more content" click="addContent()" />
          <mx:Panel id="mypanel" >
          <mx:Label text="hi" />
          <mx:Label text="hi" />
          <mx:Label text="hi" />
          <mx:Label text="hi" />

          private function addContent():void
          var newLabel:Label = new Label();
          newLabel.text = "hi";

            Thank you. This works, but only if I do not set layout="absolute" in the panel.

            I am trying to achieve the following:

            I want a panel which contains a tabbar and a viewstack. The tabbar, obviously, controls the viewstack. I would also like both these to be inset so they do not take up the full panel (i.e., there is a 10px or so border around them.)

            Unforunately, I cannot set the left/right/top/bottom attributes if the layout is not absolute. Equally frustrating is that when I set the layout to absolute, I get vertical scrollbars instead of a resized panel.

              Here is a sample:
              <?xml version="1.0" encoding="utf-8"?>
              <mx:Application xmlns:mx=" http://www.adobe.com/2006/mxml" layout="absolute">

              <mx:Panel id="pan" x="246" y="173" layout="absolute" styleName="OuterPanel">

              <mx:TabBar dataProvider="stack" tabHeight="33">


              <mx:ViewStack id="stack" resizeToContent="true" top="33">
              <mx:Canvas label="one" width="450" height="200" backgroundColor="#000000"/>
              <mx:Canvas label="two" backgroundColor="#FF0000" width="700" height="500" borderStyle="solid" borderColor="#000000" borderThickness="4">
              <mx:Canvas label="three" width="200" height="200"/>



              When I click a tab, I would like the panel to resize so the selected canvas fits completely! Unforunately, scroll bars show up instead. There has to be a way to do this, I just can't figure out how. Eventually I will only care about the panel shrinking/expanding vertically, as the width will be fixed.
