Please see screen shot. screenshot When I scroll the pane , the first row containing the images stays well within the panel..but if you notice the second row of checkboxes , it scrolls out of the panel.

I have 3 JPanels and I want to place them all in one JPanel. I used the GridBagLayout for the main panel. But only one panel is getting added.
