Jpanel add/remove component redraw problem

Question

I have a JPanel using a GridLayout for a layout manager. The Jpanel has 2 components. When i remove one component ( using remove(Component comp) method) , and call updateUI on the JPanel, it removes the component but retains the original size. i.e It does not shrink to the size of the one component it has.
How can the required effect be achieved?
Thanks

I have a JPanel using a GridLayout for a layout manager.Well you have a structure like:
parentPanel
    GridLayoutPanel
        component1
        component2Well it depends on the layout manager of the parent panel. If, for example the parentPane is using a BorderLayout, then the GridLayoutPanel will always be resized to the maximum space available and therefore the remaining component will also be resized.
So you could use a FlowLayout in the parentPanel and it will respect the size of the GridLayoutPanel. So you resulting code would be something like:
gridLayoutPanel.remove(...);
parentPanel.revalidatge();
