And also , when the second is closed, the fist is opened !!

Not sure what you mean by a form? Is it a window like a Frame or a Dialog?
One way to swap the GUI being shown in window from one panel to another panel is to use CardLayout.

Otherwise post a small, simple program that compiles, executes and shows the problem.

form means a JFrame 'form' http://dl.dropbox.co...33652950/ss.jpg

Did you look at the CardLayout class? It allows you to easily change what is shown on a GUI.

[Paulo_Jorge]

yes !! bu i want do it in code !!

example , click login button and the login panel hides and the new panel shows up ! in this new panel, i click, for example, change user, and this panel hides, and the login panel shows up again !!

Using CardLayout would be much easier.

Do you have code that shows what you want to do and that you are having problems with?
Or make a small simple program that compiles, executes and shows the problem and post that here.

If you only hide a panel for a short time simple call setVisible(false) on the main frame, while you create and show the 2nd panel. When you're done with the 2nd panel, dispose() it, and setVisible(true) the first again.

Oh thanks ! ! setVisible(false) - of coursse !! thanks

[Paulo_Jorge]

setVisible(false) doesnt work !!

String pass = JTPassword.getText();

        if (pass.equals("admin")) {

            JLErrado.setVisible(false);

            // if the in the texfield is correct, this jform shoul disappear and the other appear !!

            new LOGIN().setVisible(false); // dont work !! 

            new Desk().show();

        } else {

            JLErrado.setVisible(true);

        }

Can you make a small, simple program (SSCCE) that compiles, executes and shows your problem and post it here for testing?

[Paulo_Jorge]

How can I make that ??

[Norm]

One way is to Use an editor.
