JMenuItem Problem

Hola!

I think you need to give us some more code, and tell us more what doesn't work and what works. An I guess that you talk about JButton , couse JMenuButton doesn't exist, or am I wrong?

Best regards
Fredrik

Hi fredrik....
thank you for responding!

The link below will take you to my program. I hope that you can solve the problem that way.
What I want to do is: I want to put an ActionListener on the JMenuItem(s). When the user picks that menu item, a specific text will be inserted into the text are (for that i use replaceSelection).

Thank you!

Oh the link =)

Det her er én måde at add'e en actionlistener til en menu...

MenuListener listener = new MenuListener();

menuItem01 = new JMenuItem("Nytt");
menuItem01.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_N, actionEvent.CTRL_MASK));
menuItem01.addActionListener(listener); <<- her add'er du en actionlistener.
menu.add(menuItem01);

menuItem02 = new JMenuItem("Öppna");
menuItem02.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_N, actionEvent.CTRL_MASK));
menuItem02.addActionListener(listener); <<- her add'er du en actionlistener.
menu.add(menuItem02);


......

private class MenuListener implements ActionListener
{ 
  public void actionPerformed(ActionEvent event)
  { 
      Object source = event.getSource();
       
      if (source == menuItem01)
      {
        htmlTextArea.replaceSelection("frankfrickytastic");
      }

      if (source == menuItem02)
      {
        htmlTextArea.replaceSelection("hejsa");
      }

  }
}


Håber du kan bruge det...

Hi!

It didn't really work this time either =(.
I wonder, could it have something to do with focus, I mean when I click on the menu, the textarea looses the focus...i don't know, and maby because of that the text can't be inserted. What do you think?

This little example do what you are asking for.
I hope it's useful...

      private JMenuItem hejsa;
      private JMenuItem farvel;

      public MenuTest()

          final int DEFAULT_FRAME_HEIGHT = 300;
          setSize(DEFAULT_FRAME_WIDTH, DEFAULT_FRAME_HEIGHT);
       
        addWindowListener(new WindowCloser());

        contentPane.add(textArea);
