JFrame

Hi,

I created a JFrame with a JButton.If i pressed the JButton
I am calling a JInternalFrame .
Here My problem is once the JInternalFrame comes ,the
JButton in the JFrame is not visible.
Is there any method to avoid this.How will solve this problem.

Here is My code.

Here only one JButton  Userdetail is  visible.If i click that JButton it will call another JInternalFrame.

}
if i press the JButton this JInternalFrame is coming but the JButton is not visible.

this is a correct code for Jmain:

you have to initialyse your JDesktopPane in Jmain, and not any more in your actionPerformed method, and define it as the ContentPane of your JFrame!
PS:no modifications for your JInternalFrame

    {
    JLabel l1,l2,l3,l4;

    //passcheck pc;
    //error ee;
    //boolean bool1,bool2;
    public Jmain()
    {
    int inset = 50;
    setContentPane(desktop);
    Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
    setBounds(inset, inset,

If you could include your code it may help someone determine how to avoid your problem.

You can set the size, with setSize(Dimension d) and the location, with setLocation(Point p), of the internal frame within the container.  That way you can put your internal frame somewhere that the button isnt.

If that doenst help include your code and someone with more experience would surely help you.
