Issue in Displaying panel

[Raj kalaria]

I am stuck up in my Gui design for Swings

I have three panels in my frame
panel 1 will have the symbol(the symbol is on Right Hand Side)
Panel 2 has one lable, two radio button and one file chooser button

panel 3 has a group of check box button

Now initially panel 3 is invisible, once the user selects one of the radio button(New User) from panel 2 it will be visible. if the user select other radio button (Profile user) the panel becomes invisible

My problem is that when i test my application, Panel 2 is takes the space of itself and panel 3, when i press one of the radio button panel 3 becomes visible and the frame looks good(as iwanted) but when the user press another button (profile user) the panel 3 is invisble, but once again panel 2 takes the entire place of frame
and UI looks bad.

I am using NetBeans IDE ( so it takes GroupLayout by default)

Please throw some light so i can try something.

Your layout manager is the culprit here. Change it to suit your requirement.

thanks maneesh,
I tried to change the lay out, but it is giving me a hard time.
can you look at my code and suggest, so that i can pick it up from there

public UserConnectedFrame_1() {
      
        System.out.println("load");
        initComponents();
        initCustomComponents();
        NewUserPanel.setVisible(false);
        System.out.println("Size "+BrowsePanel.getSize());
    }

I would suggest you to use a GridLayout with 3 rows and 1 column for the three panels. In this way you can specifically assign the positions for Panels either at run time or during the editing.

JPanel mainPanel  = new JPanel();
mainPanel.setLaoyut(new GridLayout(3,1,0,0));
JPanel panel1 = new JPanel();
JPanel panel2 = new JPanel();
JPanel panel3 = new JPanel();
mainPanel.add(panel1,0,0);
mainPanel.add(panel2,1,0);
mainPanel.add(panel3,2,0);
mainPanel.revalidate();

This is a small code snippet which shows how to add the Panels.
