Showing JDialog in taskbar not working

Question

I\'m using the below code to showing JDialog on taskbar and is perfectly working in JDK 1.6.

public class test8 {   
    public static void main(String[] arg         


        

Answer 1

The problem is that certain constructors of JDialog create a dummy frame owner if the owner is null for historical reasons. But a Dialog must not have an owner to be visible like a top-level window. I.e.

JDialog d=new JDialog((Window)null);
d.setModalityType(ModalityType.TOOLKIT_MODAL);
d.setVisible(true);

will work.
