Java GUI Design view not showing completely but code works

Question

I am new to Java GUI I deigned and window and menu item using java design tool.But when I want to create window for menu item say New contact I did not find an option to do that in event handler so I did it manually by coding it.But when I go to design part and click on New Contact it does not show the window I created via code.

Here is the screen shot of deign view -when I click on New Contact nothing happens.

Now in the source code when I run it I get the window I coded

Is there any possible way I can make it work in design part? I did not find any option to do it in Add Event Handler

1. You do not want a JFrame to show another JFrame -- that's a bad GUI design since it means that your application is actually two applications. Better to show a dialog window such as a JDialog. Please see The Use of Multiple JFrames, Good/Bad Practice?
2. If you want to design a 2nd window, create a new Java program in NetBeans, one that creates this second window (again, better for it to be a JDialog, not a JPanel)
3. Give it a constructor that allows passing in the parent window, and then pass that to the JDialog super constructor
4. And then in your ActionListener code above, create a new object of this new program, passing in the current JFrame.

In the future, please post code as code-formatted text, not as an image, since this way we can copy, paste, compile and run it if we want, allowing us to better understand your code and your problem.
