从JPanel内的JButton替换当前JPanel而不是JFrame

Question

I have a JFrame and I use it as the main one and change JPanels inside the same JFrame. The first JPanel is already inside the JFrame ,so I can replace it by "this.removeall() then ,this.setContentPane(new JPanel2)" because "this" here invoke the JFrame itself.

In the other JPanel, I want to make a JButton to replace the current JPanel with another one. The problem is that I can`t do the same code before because "this" here invoke the JPanel not the JFrame.

The question is how can I write the code inside the JPanel allow me to get the JFrame to change its "setContentPane" to view the second Panel?

I have found the answer in using CardLayout .. this video helped me solve the problem

CardLayout on Netbeans video

Answer 1

I want to write the code in the buttonActionListner in the JPanel. I will not write that code in the JFrame, so every JPanel can be added and removed to call another one independently

and

@AndrewThompson-In the design of the interface we used buttons not CardLayout or Tabs. I wanted to make all the application Panels and change them one by one in one JFrame

have to call for parent ( JFrame , JPanel ),

validate(); // for Java7 revalidate() for JFrame
repaint();

after remove an add a new JPanel , only once time and as last code line

as @AndrewThompson mentioned better, easiest and simpliest way could be to use CardLayout
