Hi :

Does anybody know how to scroll a group ? I always try

Group g = new Group(p, SWT.V_SCROLL);
g.getVerticalBar().setVisible(true);

but get a null pointer exception on the second line..

Please help !!! I have an urgent deadline in a bioinformatics app.

Hi,

you need to investigate ScrolledComposite. Put this into your group. See
the ACPI doc for ScrolledComposite for how to use it.

If you want the whole group to scroll put the group into a
scrolledcomposite if you want the content of the group to scroll put the
scrolledcomposite as the direct child of the group and put all other
composites in the scrolledcomposite.

Make sure that you define decent sizes on the child component and use
the hints for minheight and minwidth on the scrolledcomposite to make
sure that scrolling appears at the correct time.
