12e3e0e477cd package custom, module and imports ok Frank Benoit <benoit@tionex.de> parents: diff changeset	42 * 1) Set the size of the control that is being scrolled and the ScrolledComposite

12e3e0e477cd package custom, module and imports ok Frank Benoit <benoit@tionex.de> parents: diff changeset	45 * 2) The second way imitates the way a browser would work. Set the minimum size of
