I am trying to get a JProgessBar to appear (in indeterminate state) and
animate while a database is connecting and then disappear when connection is
made.  Here's my attempt at code:
progressBar.setIndeterminate(true);

I've got a problem with paint(). My window needs a complete redraw if
the window size changed. Thus I added a repaint() in the
componentResized() callback.
This callback is called -- I checked.

I have an application where entering certain numbers changes the data
held, I had observers looking at these observables and when they are
notified they make changes to what is displayed on screen, one of these
is some swing graphics. I do a repaint() in the observer but when I run

I know this is probably poor implementation on my part but I've got a
GUI application that needs to popup a window with several controls on
it that allow some options to be set. I implemented this popup as a
JFrame and now, of course, when you touch the underlying GUI, the popup

I am using Action objects when building my JCheckBoxMenuItem and
JToggleButton items in the menubar and toolbar.
I assumed this would keep the two in sync just like happens with the
"enabled" property, but it seems I somehow have to manage the

I have defined a custom Action that extends AbstractAction for quiting
my application. This action performs all types of house-keeping before
calling System.exit(0). Now I would like to perform this action when

It's supposed to read in a CSV and a certificate containing a private
key and output a decrypted version of the file. I set the code up using

Hello, I have a question.
Does anybody know how to overlap (I don't know if this is the right term

buttons, one on the left is the large button and on the right is an
arrow that will pop-up a JMenu when clicked. This would look pretty

I'm attempting to create a JFormattedTextField that will accept only a
certain set of characters, but there is not a limit on the length of
the string. I have put together a MaskFormatter like this (pardon any
typos, I'm having to type it in from scratch):

I would like to look for a filename consisting of at least an 'a' and
'.txt' and then let the program just search the disk for it. When
looking at file I/O (e.g. at mindprod) I get the impression that I won't
be able to just scan through the filestructure on disk. Is this a

I have N number of panels that I need to switch between, only 1 panel being
visible at a time.  But I do not
want Tabs shown.  My first thought was to use a parent panel with a layout
of BorderLayout and place the
