Q: I'm resetting the TitleBorder's title via setTitle, but no change occurs....
I'm trying to make a dialog box containing a panel whose TitleBorder's text
dynamically reflects the function of the list box within it. The title text and the list box
contents should change according to the buttons pressed elsewhere in the dialog
box. I'm resetting the TitleBorder's title via setTitle, but no change occurs. Do I need
to update the dialog? If so, how do I do this?
Answer: Yes, you need to update the dialog.
How? Call the validate() and invalidate () methods
Q: everytime you create a dialog-object, the dialog pops up in the upper left
corner of the screen. Now I want it to be automatically placed in the center of the
application's frame.
Answer: private void center() {
Dimension screenDim = Toolkit.getDefaultToolkit().getScreenSize();
setLocation( ( ( screenDim.width - getSize().width ) / 2 ),
( ( screenDim.height - getSize().height ) / 2) );
}
You can call this anytime after calling pack() on the JDialog, before
setVisible().
