Thread: JInternalFrame not being Displayed

I have a "MainFrame" which extends a JFrame and in there I have a variety of diferent components. Some of which is a Menu Bar with three Menu Items. I have an ActionEvent on clicking the 'Config' menu item.

When I click the Config menu item, I run the following code:

   private void menuConfigActionPerformed(java.awt.event.ActionEvent evt) {                                           
        ConfigFrame configPopUp = new ConfigFrame();
        configPopUp.setVisible(true);          
    }

The ConfigFrame extends JInternalFrame.

All I want to do is show this ConfigFrame once I click the Config menu item. For some reason, the ConfigFrame doesn't ever show?

Please can someone help me where to look?

Thanks

I haven't manually added any code to add the ConfigFrame object to a Container. I thought that I just had to create a New Instance of the ConfigFrame object and call the .SetVisible method to see it. Are you saying I have to add the ConfigFrame object to another container say a JFrame?

Add print statements to ensure the action is being executed and then post the ConfigFrame code if you still cannot get it to display. If written correctly, it should be able to be shown on its own. BTW - a JDialog is more commonly used as a child interface to a JFrame because of its ability to set modality.

Ok thanks. I have just tried the same thing with a JFrame instead of JInternalFrame and it worked. I will look into the JDialog you have mentioned though.

Thanks to you both.

Maybe what you want is a JDialog instead.
Edit: Whoops, didnt see the other post.
