从一个Jframe到NetBeans中的JPanel

Question

I have created a login form where users will enter their credentials and navigate to other frame. This frame to frame transition is working fine. But I also added a admin login from a invisible label in the bottom.

When the admin clicks the invisible label on the user login frame (NewJFrame), a custom login panel (Admin) should be opened.

But when I click the label, JPanel is not showing.

private void jLabel6MouseClicked(java.awt.event.MouseEvent evt) 
{
    Admin o = new Admin();           // Admin is a login panel
    NewJFrame o1= new NewJFrame();   
    o1.add(o);                     // Throwing an Exception here

    // TODO add your handling code here:
}    

Answer 1

you are adding it on mouse click ? i think you should add it at start and on mouse click , just make it visible by yourPanel.setVisible(true);
