I have a JFrame (Frame1) and in the constructor, I want to provide for an
exit confirmation dialog. I add the code as follows:
public class Frame1 extends JFrame implements WindowConstants {
public Frame1() {
super ("Focus Frame");
//Code left out
setDefaultCloseOperation(WindowConstants.DO_NOTHING_ON_CLOSE ) ;
WindowAdapter a = new WindowAdapter() {
public void windowClosing(WindowEvent e) {
int confirm = JOptionPane.showOptionDialog(Frame1, "Really
exit?",<---ERROR HERE
//--->>>Error is: "Frame1.java": Error #: 300 : variable Frame1 not found in
anonymous class of constructor Frame1()
//-->>>I UNDERSTAND why this is occurring, but how can I remedy it?
"Exit Confirmation",
JOptionPane.YES_NO_OPTION,
JOptionPane.QUESTION_MESSAGE,
null, null, null);
if (confirm == 0) {
//Frame1.dispose();
System.exit(0);
} //if
}
};//new
//Frame1.windowDeactivate();
addWindowListener(a);
Thanks
RON
