JTabbedPane

[Anagha Medicharla]

Hi ,
In my project I have created many forms like candiateInfo,Resume etc.(which extends JFrame)
Now I want to use JTabbedPane.Menas if I click on one tab it should take user to resp. form.Code I have written like this(it's in contstructor of that class):
[code]{ contentPane = (JPanel) this.getContentPane();
contentPane.setLayout(borderLayout1);
JTabbedPane tabbedPane = new JTabbedPane();
String tabs[] = {"CandidateInfo", "Resume"};
tabbedPane.addTab(tabs[0], new Candidate());
tabbedPane.addTab(tabs[1], new Resume());
tabbedPane.setSelectedIndex(0);
add(tabbedPane, BorderLayout.CENTER);

this.setSize(new Dimension(400, 300));
this.setTitle("Frame Title");
}
****It's giving runtime error- IllegalArgumentException:a window added to a conatainer.Can anybody explain me why it's giving this error.

Thanks in advance
Anagha

Ah your problem is that your forms extend JFrame (which is an individual window Object and does not extend Component) You need to extend JPanel in these forms to be able to add them as components in a tabbed pane. If they also need to be standalone windows soemtimes, just make a constructor of the form that creates a JFrame and adds itself to the JFrame.
Hope this helps.
