The method setShowFocusedControl() in ScrolledComposite is missing whereas it is available in SWT since version 3.4. My problem is that the default behavior in RWT differs from that of SWT: the

Steps to reproduce (both in RWT and SWT samples):
1. Start the application (initial states shown in scrolledcomposite-RWT-state1.png and scrolledcomposite-SWT-state1.png)
2. Click on a tree item
3. In the RWT sample the root scrolled composite is automatically scrolled so that the header label disappears (scrolledcomposite-RWT-state2.png).
4. Notice that in SWT the root scrolled composite does no scrolling at all (scrolledcomposite-SWT-state2.png). However, if in ScrollTestShell.java you uncomment line 35 (scrolledComposite.setShowFocusedControl(true);), the behavior will match that of RWT (scrolledcomposite-SWT-state3.png). But this is NOT the default behavior.

ScrolledComposite#setShowFocusedControl(boolean) is implemented. Now there should be no difference with SWT.
