Newbie --- How to call an internalFrame after clicking a button?

[huiyanx2]

Hi all,

Do you know how to call new internalFrame after clicking a Jbutton in other internal Frame? As I use MDI, I don't know how to add that new internalFrame to my destop manager ?
Also, Should I use 'AddInternalFrameListener' instead of addActonListener in internalFrame? If yes, what is the method should I use to replace 'actionPerformed'?

Following is part of my coding:

public class lw_SearchPO extends JInternalFrame implements InternalFrameListener, ActionListener{

JButton jButton1 = new JButton();

private void jbInit() throws Exception {
jButton1.setText("Search"
jButton1.addActionListener(new
java.awt.event.ActionListener() {
public void actionPerformed(ActionEvent e) {
jButton1_actionPerformed(e);
}
});

void jButton1_actionPerformed(ActionEvent e) {
MainFrame_Pur MainFrame_Pur = new MainFrame_Pur();
lw_updatePO lw_updatePO = new lw_updatePO();
lw_updatePO.addInternalFrameListener(this);

// Can't access desktop even desktop is declared public!
MainFrame_Pur.desktop.add(lw_updatePO);
lw_updatePO.show();
lw_updatePO.pack();
lw_updatePO.setVisible(true);
}

}

Thanks!

Joyce

Hi huiyanx2:

You are doing it right, but you need to receive a pointer to the Main class to access its desktop. In the constructor:

public lw_SearchPO(<MainFrame_Pur class name (type)> parent)

Then declare the parent public and access its desktop.

If the desktop is public, your class must be able to reach it.

For the actionListener issue, it depends on why do you want to add an InternalFrameListener. If you want the main application to be notified of the button event, the actionlistener added to the button should notify the Event Manager of the application, so it will be enough.
