You need to set the minimum size for the ScrolledComposite:
scrollableCom.setMinSize(innerComp.computeSize(SWT.DEFAULT,
SWT.DEFAULT));
You also need to do this every time the text size changes.
Note the following lines in your code below are not doing anything useful:
scrollableCom.setLayout(new FillLayout());
innerComp.setSize(innerComp.computeSize(SWT.DEFAULT, SWT.DEFAULT));
Also, I am not sure why you have innerComp - you could just parent the Text
widget directly in scrollableCom.
See the following examples:
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.swt.sni ppets/src/org/eclipse/swt/snippets/Snippet5.java?rev=HEAD&am p;content-type=text/vnd.viewcvs-markup
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.swt.sni ppets/src/org/eclipse/swt/snippets/Snippet166.java?rev=HEAD& amp;content-type=text/vnd.viewcvs-markup
Also, the javadoc for ScrolledComposite gives two examples of how to use the
API.

Hi Veronica
Thanks, it worked fine. It was just the missing link :-)
