Hi there,

Due to my inadequacy, I need some help for one ~{!0~}simple problem~{!1~}.

(1) The GUI screens (frame/panel structure) are structured as ~{!0~}multiple levels (or generations)~{!1~} with only one level of the screen is displayed at one time. In other words, a first level (or parent) screen brings up a child (next level) screen based on the user selection/data-entry. The parent screen is either hidden or disposed (by its child), however the parent screen can be redisplayed with all the ~{!0~}entered~{!1~} data if user requested (from the child which has such a requirement). Sometimes a grand-child screen needs to dispose itself and its parent, and then brings back the grand-parent screen. It seems a simple task but me just unable to implement this option.

I must missing some key concept (or not understanding fully) of the Java features. Hope you don~{!/~}t mind that I ask for your help. Thanks in advance for all your time.

Well, lets say you are using JFrame and JDialog for such a task.
JFrame frame = new JFrame();
frame.setVisible(true) will bring up the JFrame object.
Another container object lke the JDialog we just talked about addede to it would be like this..
JDialog dialog = new JDialog(frame, "Title", true);
An actionEvent would bring up the dialog from the frame like this...
dialog.show()
and then.. to hide the parent container being the frame..
frame.setVisible(false);
another actionEvent to bring up the parent container and hide the child container being the dialog will go like this...
frame.setVisible(true);
dialog.dispose();
hope that helps you...
