Look & Feel and the JTree

Hi,

I'm using swing 1.0.3 and jdk 1.1.6.
Development Platform: Windows NT 4.0
Deployment Platform : Windows NT 4.0 Application

I've implemented my own renderer and editor for a tree (JTree). I've did that by extending the classes 'BasicTreeCellRenderer' and 'DefaultCellEditor'. Then I've
implemented my own 'getTreeCellRendererComponent()' and 'getTreeCellEditorComponent()'. Both methods return a 'JPanel' which include a 'JLabel' and a 'JButton'
(I have to do that, because I want to display an image and a button with another image and text).
Now my problem:
Everything works fine with the 'Metal Look and Feel'. But if I try the Windows or Motif L&F the tree doesn't care about the space the components (my renderer and editor) do need (which means, the tree doesn't care about the getPreferredSize()).
It only shows the top of each renderer and cuts the bottom because the renderer (and editor seem to be too big).
How can I tell the Motif and Windows L&F, that they should ask for the preferredSize of its compoments and adapt to them.

Can you help me ?

Thankyou in advance,
JFM.

i don't have any documentation round here, but you can check if JTree has .setRowHeight method (or something similiar). I'm almost sure that JList and JTable has one. If JTree has such method, you can set the desired height directly.

Invoke JTree.setRowHeight(0); <-- That is a zero.

This tells the UI manager that the preferred size will be used to size the components.
