GridBag Layout

[selvas kumars]

I am having 3 components JList,SelectionButton ,Jlist in horizontal order.Both JList are of equal size and selectionButton is centered and width is small..Looks fine even when resized..
The problem comes when i add items to the first Jlist.This becomes smaller and the last JList increases it's width ..
After selection of items from left to right still the size remains constant.How to solve this problem.At any point,both Jlist should be of equal width..I don't want to use setPreferredSize().

Constarints for the JList used
1)Constarints for first JList
GridBagConstraints gbb = new GridBagConstraints();
gbb.gridx=0;
gbb.gridy=0;
gbb.gridwidth=4;
gbb.weightx=1.0;
gbb.weighty=1.0;
gbb.fill = GridBagConstraints.BOTH;
2)Constraints for second JList
gbb.gridx=6;
gbb.gridy=0;
gbb.gridwidth=4;
gbb.weightx=1.0;
gbb.weighty=1.0;
gbb.fill = GridBagConstraints.BOTH;
Thanks

Change the gridBagConstraints.fill to NONE. This will prevent the component from resizing from its original shape. Also, it's good to set weightx and weighty to 100 first.
