code for a dialogue box to exit

[sugard]

I am trying to do this thing. When someone presses the exit button, a new window will be displayed asking the user whether he is sure to exit also 2 buttons will be displayed. One displaying yes and a one displaying no. If yes pressed the application closes if not, the user will be returned to the application. Though, I dont have an idea what code i need to place under each ActionPerformed for the button Yes and No. Can please someone help me how to do this?

thanks very much

To display a "Are you sure you want to exit? yes/no" dialog, you can use JOptionPane. This is very simple -- one line of code.

To react when the user tries to close the main frame, use a WindowListener:

In this case, be sure to set the default behaviour of the window to do nothing on close -- you will be manually coding it:

mainWindow.setDefaultCloseOperation(WindowConstants.DO_NOTHING_ON_CLOSE);
