I want to create a bitmap (an Image of some sort in Java?) from a graphics
display in one Swing component and blit it to another Swing component to be
displayed.
Can anyone tell me how to best approach this?

I've tried everything that I can find from the Java 1.4.2 API specs for
JSplitPane in order to control the splitter, but almost nothing works.  I
can manually drag it into the place I want, but no code I write affects
it, or actually works the way it says it should.

Hi all...
I'm developing a java application based on the old Supremacy board game...
The display is a large map of the board, which is zoomable and scrollable.
I'd like to place several components on top of this, such as an 'Empire

i want to write a console- or shell-like object (extends JTextPane).
if the user presses the up-key and down-key, he should be able to
"scroll" through his already entered commands.
i have it somehow realised with a KeyListener like that:

We make multiple buttons, e.g. [Joe], [Mary], [Paul], [Suzy], etc. And

When we dispatch an event from button A's ActionListener onto Button
B, if the event specifies a left mouse button click, it seems to be
nullified, i.e. ineffective. Does someone know the cause of the
problem and solution?

I have a swing interface with radio buttons in a button group. I would
like to be notified if the user clicks on one of the buttons BEFORE
the action actually take place because under certain conditions I
could refuse the action. I guess one way would be to use a normal

I have a non modal JDialog in which information about the current demo
is displayed. When changing the look and feel, the buttons and other

Does anyone know why the argument of setActionCommand (for example in
JButton) is a String rather than an Object?
Since the only thing that I ever see done with the value of actionCommand is
to compare its reference it could be any kind of Object.  Furthermore if it

Hi, Goodmorning,
I run into an ArrayIndexOutOfBoundsException.
From the stack trace we can see that it does not really have anything

Can anyone suggest a way that I can have JColorChooser's
showDialog appear initially in its RGB tab?  (ie index 2)  
For example, when the program below runs, it initially
displays the "Swatches" tab (ie index 0), but there doesn't

I made a simple drawing applet in Java, using Graphics 2D API. You can
draw shapes, select them,
drag them, etc.
I tried to add zooming abilities by overriding the paintComponent

I'd like to change the L&F of the JTable Header but I'm not sure how to do
this.
Basically, I want the header columns to look flat instead of raised, with a
custom background color.

i'm writing a textbox (extends JTextPane) witch can handle syntax
highlighting. i handle colorization with doc.setCharacterAttributes.
my textbox also supports undo/redo but the problem is, that the
colorization-steps are also made undoable (but they shouldn't)!
