Having trouble with scrollpanes
Hi all,
Been trying to get a scroll pane to work on a text area, problem is i don't fully understand how the frames are set up, and although i'm copying demos best i can all i get is the normal text area without the scroll bars on it.
This is my main piece of code for the frame, can someone tell me where i'm going wrong? Thanks
publicclass Chatextends JFrame
{
privatestatic JTextArea output =new JTextArea();
private JTextField toSend =new JTextField();
private ActionMap actionMap1 =new ActionMap();
private JLabel shortDisplay =new JLabel();
public BackgroundPanel bp =new BackgroundPanel();
public showAd showAd;
Image img;
public Chat()
{
try
{
jbInit();
}
catch(Exception e)
{
e.printStackTrace();
}
new getChatter().start();
new showAd().start();
}

}
});
shortDisplay.setText(Client.name);
shortDisplay.setBounds(new Rectangle(10, 10, 125, 25));
this.getContentPane().add(shortDisplay,null);
this.getContentPane().add(toSend,null);
this.getContentPane().add(output,null);
this.getContentPane().add(outputPane);
}
