Automatic resizing of a Container

Hi


Is there a way to automatically rezize a container when one of its
components has changed its size?

The organization of my various components can be represented in XML (SwiXML
compliant) by:

<panel id="panel_media" layout="borderlayout" 
  border="EmptyBorder(10, 10, 10, 10)"
  constraints="BorderLayout.CENTER" >
  <vbox constraints="BorderLayout.CENTER" >
    <panel />
    <panel id="panel_video" maximumsize="180,140" preferredsize="180,140" 
      background="black" />
    <panel id="control_video" maximumsize="180,35" preferredsize="180,35"
      border="BevelBorder(1)" />
    <panel />
  </vbox>
</panel>

When I change the size of the JPanel with ID "panel_video", I would like to
have the whole JPanel with ID "panel_media" to be resized automatically.
The Java code I use is:

....
// retrieves JPanel with ID panel_video   
JPanel videoPanel = getVideoPanel(); 
// retrieves JPanel with ID panel_media   
JPanel mediaControlPanel = getMediaControlPanel();
... Other changes inside videoPanel
videoPanel.setSize(newSize);
mediaPanel.updateUI();

I tried also by repacking the whole application frame without any success.

Did I miss something?
