It's been a while since my last encounter with Swing so it
must be something i simply forgot.
I extend a JPanel and implement MouseListener. All the
methods have empty bodies except for:

I have a JPanel with a bunch of JComponents inside. Now I want that the
user can drag the mouse over all of them and draw a selection rectangle
over them.
How do I do that? Do I have to use and implement the glassPane?

Ive currently set my program up with a simple JFrame interface and a couple
of JMenus and JMenuItems. Just enough to allow me to read in some files and
start the program running.
The program starts about 50+ threads running in the background. Before the

Do JTables update themselves?  That is, if I changed the data that
pouplates the TableModel behind the JTable programmatically, will the
JTable update?

Hi,
I would like to make a JTextArea automatically size adjustable.
Specifically, for example, if I have a JTextArea, I'd like to
setText()

I have a Component with a KeyListener. When the user types a key, say x, a
sorted JList in a JDialog shall pop up and immediately select the first X
entry.
How can I do that? I have already added a KeyListener that listens for a

In the following code, I create an awt Frame. Unfortunately, when I
run the resulting Java application (on Windows) and use the mouse to
resize the window, none of the Frame's resize/setSize methods get
called. Can anyone explain why this is?

are there advanced dialog classes in swing (or elsewhere, free) that allow
wrinting an Options, Preferences etc dialog easily? Or multi-step dialogs?
thanks!

I want to draw a string of varying size inside a box.
g.drawString("........string....", x, y)
g.drawBox(x, y, w, h);

I work with sdk 1.4.2 on Win2000 on a gui/swing application.
Once in a while, randomly, appears the following stack trace::
java.lang.NullPointerException
       at sun.awt.windows.WInputMethod.dispatchEvent(Unknown Source)

Do JLabels automatically word-wrap if the label text is too long?  If
not, is there a way to show a really long line without using HTML or
JTextComponents?

I posted this on comp.lang.java.programmer last week but nobody answered. I
probably should have posted to comp.lang.java.gui in the first place; can
anyone give me a hint on how to solve this problem?

This should be easy for Swing experts, but I have no success. I have tried
every obvious solution (requestFocs()...)
I have this little working code (see below) that shows a JPopupmenu with a
JList when you press the "arrow down" key. This is nice, but it does not

imagine the user has to choose one of, say, 100 items. They should be
displayed when he clicks on a word in a frame or panel, and he can choose
one (the 100 items cannot be structured in submenus).
What is better: To display them in a nice little scrollable popup menu

I'll describe what I think I want, which hopefully conveys my intent.
I would like a text label with a (1,2) gridlayout which is a container for 2
JComponents.
The JComponents will register action listeners and visually be just a block
