I've got a JTable that I'd like to have invoke an Action when a user
double-clicks on a row. I found code on Google to get me started on

I have a simple program below where the user can draw rectangles on a panel.

Has anyone out there written some very simple code to create a JTabbedPane
that I could compare mine too?
I have tried multiple times to create one using the code given on the Sun
tutorial but must be missing something vital.  I just get a very small blank

Is it possible to have an owner (frame) to have it's menu display over
it's dialogs?  I assumed incorrectly that owner's menu would have

I'm currently designing an application that will have floating and
docking panels.  In a sense, it will look like an MDI application, but
it will allow the user to drag "panels" outside of the Frame or dock
them to the inside.

I have a screen with many radio buttons (~24)... most people will be
tabbing through all these fields making selections, instead of using
the mouse.  How do I give a visual indication of what JRadioButton

I'm having some trouble with JInternalFrame and JDesktopPane.
When I'm adding a JInternalFrame to the JDesktopPane it appears behind the
JInternalFrame that's already open. How can I show the JInternalFrame above
all other open JInternalFrame(s)?

Is there any way to eliminate borders on a JFrame so that a panel will

Thanks in advance.
