It's been a loooong time since I've done any Swing work so I have a
couple of noob questions to ask about getting the following frame to
layout just right. The code was generated with jBuilder and then
massaged in eclipse to make it self contained (if you care :-)

#1) I had to create jPanel3 and jPanel4 to get the widgets in the two
tabbed panels to appear at the top of their respective panes.  If I do
not add panel4 (commented out below) then the the gridBag seems to end
up centered in the middle of the pane. See the difference between how
tab1 and tab2 display in this app? Is that the recommended way do do
this? I would have thought there would be a better way.

#2) I would like to have the LHS of the splitPane be at, say, 75% of
the width of the window. How is this best accomplished? I could set up
something to watch for resize events on the enclosing panel and set an
explicit preferred size. Again... is this the recommended way to do this?

Thanks for your help.
