Hi,

I have problems using GridBagLayout for positioning JInternalFrames on a
JDesktop.
For instance, I have 2 JInternalFrames and I neither set the size nor the
preferedSize of the InternalFrame because I thought my JInternalFrames would
get the size from the GridBagLayout-manager but it doesn't work at all.

[...]
   desktop = new JDesktopPane();
   gbl = new GridBagLayout();
   desktop.setLayout(gbl);
   content.add(desktop);
[...]
   GridBagConstraints gbc1 = makegbc(0, 0, 1, 5);
   gbl.setConstraints(treeIFrame, gbc1);
   desktop.add(treeIFrame);

   GridBagConstraints gbc2 = makegbc(1, 0, 4, 1);
   gbl.setConstraints(tableIFrame,gbc2);
   desktop.add(tableIFrame);
[...]

the makegbc is nothing more than:
private GridBagConstraints makegbc(int x, int y, int width, int height)
{
   GridBagConstraints gbc = new GridBagConstraints();
   gbc.gridx = x;
   gbc.gridy = y;
   gbc.gridwidth = width;
   gbc.gridheight = height;
   gbc.insets = new Insets(1, 1, 1, 1);
   return gbc;
}

Can anyone give me some hints?

Thx in advance
