Hi,

The java.awt.Container has a method called addImpl(..),
This takes three parameters (addImpl(Component comp, Object constraints, int
index)

When someone adds any component, this method is called automatically. So you
can overide this method to check what components are dropped onto you panel.

ie:
public void addImpl(Component comp, Object constraints, int index)
{    if(comp instanceof Button)
            // do nothing
    else super(comp, constraints, index);
}

Hope this helps

Kind Regards

Dillan Fernando
