Redraw a JPanel during runtime

Question

Hi there,
Im trying to redraw a whole JPanel during runtime.
So basically I have this panel:
public JPanel panel1 = new JPanel() {
     public void paintComponent(Graphics g) {
           super.paintComponent(g);
}That panel is added to my JFrame during initialisation.
I added an actionListener to a JButton that creates a whole new JPanel
Then i try to set the default (panel1) to the new generated JPanel:
public void actionPerformed(ActionEvent e) {
     if(e.getSource().equals(myButton)) {
     JPanel newPanel = generateNewPanel();
     panel1 = newPanel;
     panel1.validate();
     panel1.repaint();
}After i done all that, it didn't redraw the jpanel
Please advise on what I have gotten wrong.
Thanks

Answer 1

To be honest i recommend not using netbeans to code gui for a long term project which relies on code. NetBeans is useful - only for creating gui stubs and for throwaway gui prototypes but not in the long run, which is of my own experience. To be fair i have many years of coding gui's way back in the days when awt only started up.
i know gui in java is "crap" because of it's repeated code and tedious mechanism to generate ui windows so to do that you might as well hard code it yourself using a proper or better IDE - "ECLIPSE" or any linux based code editors are good also. This way you learn much more about guis.
