Trouble adding JPanel to JFrame with NetBeans IDE

[ozzyman]

Hi, I've designed some JFrame forms in netbeans which I intended to add to the main JFrame. Then I realised thats not possible so I created a new JPanel form and then copy+pasted the contents and source code of the minor JFrame form to the JPanel form.

Now I need to add the JPanel form to the main JFrame but whatever I've tried won't get the JPanel to display... Please tell me what I am doing wrong?

I tried this way:
//productsPanel is a JPanel in the main JFrame
productsPanel.add(new ProductsViewer());

I also tried this:
ProductsViewer myProductsViewer = new ProductsViewer();
productsPanel.add(myProductsViewer);
myProductsViewer.setVisible(true);


And I also tried to use these two methods after adding the JPanel to the JFrame:
productsPanel.validate();
productsPanel.repaint();


Nothing seems to get this JPanel to show.

Please help!!

Thanks

You seem to do it in reverse. You need to add JPanel to JFrame like this:

myProductsViewer.add(productsPanel);
myProductsViewer.setVisible(true);
