mouseover event

[pds8475]

hi iv got a form with 3 buttons and a textarea what i want to do is when the mouse is over the button a decription of the buttons function is displayed in the textarea.
any ideas on how i would go about writing the event?

[eRaaaa]

add a MouseListener to the button?

		JButton btn = new JButton("Dummy");
		btn.addMouseListener(new MouseAdapter() {
			public void mouseEntered(MouseEvent e) {
				area.setText("Button description here");
			}
			public void mouseExited(MouseEvent e) {
				area.setText("");
			}
		});

:confused:

Sounds like you could use .setToolTipText() method like:

cmdButton.setToolTipText("This is a button.");

tanjo, your reply sounds like the best answer to me. Another possible solution if the OP must use a JTextArea is to add a ChangeListener to the JButton since the button's state changes on rollover.

i.e.,

         btn.addChangeListener(new ChangeListener() {
            public void stateChanged(ChangeEvent e) {
               boolean rollover = btn.getModel().isRollover();
               if (rollover) {
                  textArea.append(btn.getActionCommand() + "\n");
               }
            }
         });

But again, my suggestion is much more of a kludge compared to tanjo's excellent suggestion.
