Hi Wim,
The same also happens with the second JTextArea if you press
Shift-Tab from the button. And for the same reasons. Change these
two lines in the MyTextArea constructor from true to false:
forwardFocusTraversalKeys.add(
AWTKeyStroke.getAWTKeyStroke(
KeyEvent.VK_TAB, 0, true ) );
...
backwardFocusTraversalKeys.add(
AWTKeyStroke.getAWTKeyStroke(
KeyEvent.VK_TAB, InputEvent.SHIFT_DOWN_MASK, true ) );
to
forwardFocusTraversalKeys.add(
AWTKeyStroke.getAWTKeyStroke(
KeyEvent.VK_TAB, 0, false ) );
...
backwardFocusTraversalKeys.add(
AWTKeyStroke.getAWTKeyStroke(
KeyEvent.VK_TAB, InputEvent.SHIFT_DOWN_MASK, false ) );
It's also helpful and likely to draw more response if you send
compilable code. That includes import statements. Best,
Joe Sam

Subject: weird focus behaviour with 2 JTextArea's
Hi,
I want enable TAB/SHIFT-TAB in a JTextArea to go to the next JTextArea and
not print a tab character in the JTextArea. This can be easily done with
setFocusTraversalKeys(). But I found something strange. Below is a
testprogram with one JButton and 2 JTextArea's. When the program is
started,
focus is on the JButton. Press TAB and the focus will go to the first
JTextArea and immediately to the second JTextArea. If you place the focus
with the mouse on the first JTextArea and press tab, it goes to the second
as it should.
Can someone explain this behaviour?
Below is the code of my testprogram...
public class FocusTest extends JFrame
{
public static void main( String[] args )
{
FocusTest test = new FocusTest();
test.pack();
test.setVisible(true);
}
public FocusTest() throws HeadlessException
{
super(Focus Test);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setContentPane( createContent() );
}
private JPanel createContent()
{
JPanel panel = new JPanel();
panel.setBorder( BorderFactory.createEmptyBorder(12,12,12,12));
panel.setLayout( new BoxLayout(panel, BoxLayout.Y_AXIS));
JButton button = new JButton(Test button);
panel.add(button);
JTextArea textArea1 = new MyTextArea();
panel.add( textArea1 );
panel.add( Box.createVerticalStrut(7));
JTextArea textArea2 = new MyTextArea();
panel.add( textArea2 );
return panel;
}
private class MyTextArea extends JTextArea
{
public MyTextArea()
{
super(10, 50);
Set forwardFocusTraversalKeys = new HashSet();
forwardFocusTraversalKeys.add(AWTKeyStroke.getAWTKeyStroke(KeyEvent.VK_TAB,
0, true));
setFocusTraversalKeys(KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS,
forwardFocusTraversalKeys);
Set backwardFocusTraversalKeys = new HashSet();
backwardFocusTraversalKeys.add(AWTKeyStroke.getAWTKeyStroke(KeyEvent.VK_TAB,
InputEvent.SHIFT_DOWN_MASK, true));
setFocusTraversalKeys(KeyboardFocusManager.BACKWARD_TRAVERSAL_KEYS,
backwardFocusTraversalKeys);
}
}
}
