Selecting all the text in a JTextField

Thread view:

The default behaviour when focus passes to a JTextField appears to be
for the cursor to go to the end of the text.

I would like to set it up so that all the text is selected and typing
anything will erase the old text.

How do I do this?

Thanks.

Alan

If you have a member field like

private JTextField text = new JTextField();

you can add a focuslistener to selected the text like

text.addFocusListener(new FocusAdapter() {
public void focusGained(FocusEvent e) {
text.selectAll();
}
});

If you have a lot of text fields, you can of course do this from a
central builder, a visitor or in a subclass constructor.

Thanks. What I have written in focusGained is:

((JTextField)e.getComponent()).selectAll();

In addition to the answer you got, this was IIRC a change in the
Windows L&F because Windows controls stopped automatically selecting
text on focus in W2k or so.
