SWT composite layering

I am trying to show different forms on the same composite by clicking on a tree item,which does this for me.But,the second and following forms appear below the first one.By any means can i empty the composite to display only the new forms,when required?

Put your forms in sub- composites(that is, all are in ur main composite).Then, collapse all other composites those u don't want to show.
