将一个JFrame分配给另一个JFrame

Question

I am trying to make the current JFrame become a JFrame that is stored in memory. At the moment I am correctly reading the JFrame from memory and I can get it to display but all the action listeners are not working.

        gui.dispose();
        gui = savedGUI;
        gui.setVisible(true);

This doesn't seem to be properly setting the current GUI (gui) to the saved version (savedGUI). Is there a different method I should be calling on gui rather than setVisible?

Thanks in advance!

Answer 1

当我确保所有ActionListeners都实现了Serializable时，此问题已解决。

I don't really understand what you are doing either. Why do you think you need to refer to the GUI with a single reference variable?

Just do:

savedGui.setVisible( false );

We you want to display the GUI again you do:

savedGui.setVisible( true );
