I'm finally trying to design a serious form, and I'm running into a very basic problem using BorderLayout.
I start with the base panel using a BorderLayout. To this I add JPanel jp1 in the WEST, with its own BorderLayout.
Problem is, jp1 displays with zero-width, which does not make a good drop zone for components to be added to it. I can add by dragging to jp1 in the tree view instead, but there's no way to specify, either during the drag/drop or afterwards, what the constraints should be on the component.
