how to make passive Jframe in Java

Question

hi i am using jframe,

i have a main() class on login page, when people logon than i use

adminForm = new AdminForm();                    
adminForm.setVisible(true);
this.dispose();

now i can set visible my adminForm, i have an edit and add button on the adminForm, when people push the add button, i want to open new frame

yAdmin = new Add();
yAdmin.setVisible(true);

now i want people just edit yAdmin, people can see the adminForm but they cant touch it before the yAdmin closed.

Answer 1

Instead of JFrame use a JDialog for yAdmin , make it modal with adminForm as its owner:

 yAdmin = new JDialog(adminForm,true);

or let Add extend JDialog accordingly.

Answer 2

JFrame frame = new JFrame ();
frame.setAlwaysOnTop (true);  

or you can use modal dialogue:

JDialog dialog = new JDialog ();
dialog.setModal (true);
dialog.setAlwaysOnTop (true);
dialog.setModalityType (ModalityType.APPLICATION_MODAL);
