Select text by default in swing

Question

There is any way to automatically by default select text in JTextField and JTextArea when focusGained event occurs?

You just said how to do it -- focusGained event of a FocusListener.

You can then get the JComponent whose focus has been gained via FocusEvent's getSource() method and then call the selectAll() method on it.

Something like:

FocusAdapter selectAllFocusAdapter = new FocusAdapter() {
  public void focusGained(FocusEvent e) {
    final JTextComponent tComponent = (JTextComponent) e.getSource();
    SwingUtilities.invokeLater(new Runnable() {

      @Override
      public void run() {
        tComponent.selectAll();
      }
    });
    tComponent.selectAll();
  }
};

myJTextField.addFocusListener(selectAllFocusAdapter);
otherJTextField.addFocusListener(selectAllFocusAdapter);
myTextArea.addFocusListener(selectAllFocusAdapter);

@Ricardo this answer to your question, notice, for JTextArea couldn't be selectAll the proper methods, I'd be moving with Caret to the end of text – mKorbel Nov 25 '12 at 19:37

This is what you need:

jTextField1.selectAll();

More below:

jTextField1.addFocusListener(new FocusListener() {

        @Override
        public void focusGained(FocusEvent e) {
            if(jTextField1.getText().equals(initialText))
                //jTextField1.setText("");
                jTextField1.selectAll();
        }

        @Override
        public void focusLost(FocusEvent e) {
            if(jTextField1.getText().equals(""))
                jTextField1.setText("whatever");
        }
    });

+1 quite good :-) but common issue is about [Focus is asynchronous, required invokeLater in some cases](http://stackoverflow.com/a/10293343/714968) — mKorbel, Nov 25 '12 at 18:23

Are you expecting something like

    class MyFocusTextField extends JTextField {
    {
        addFocusListener(new FocusListener() {

            @Override
            public void focusGained(FocusEvent e) {
                FocusTextField.this.select(0, getText().length());
            }

            @Override
            public void focusLost(FocusEvent e) {
                FocusTextField.this.select(0, 0);
            }
        });
    }
}
