Adding a JButton to a panel at runtime

Hello all

I am having a problem adding a component to a JPanel at runtime. My
code adds a new JTextField. However it does not appear when I click the
add button. The component count of the JPanel does rise by one however
everytime I click the add button so the new JTextfield is being added.
I have noticed that when I click the border of the JFrame the new
JTextfield appears then. I have tried to 'repaint' the frame and the
JPanel but I still cannot see the new added JTextField. I can only see
it when I click on the edge of the frame. It seems to force a refresh.
Can anyone help?

Thanks in advance

Richard

Try calling :

panel.revalidate();
panel.repaint();

The panel needs to be revalidated to relayout the child components.
