Build Identifier: 20090920-1017

If you create an ExpandBar with a lot of entries, the Scrollbar gets resized correct, but if you click on the Scrollbar to scroll or click on the arrows of the scrollbar the scrollbar scrolls only a bit.

The problem is that the variables 'increment' and 'pageIncrement' of the Scrollbar are not set. The reason for this is that the ExpandBar does an OS call in setScrollbar() instead of doing getVerticalBar().setValues(...) which sets the variables.

Reproducible: Always

Steps to Reproduce:
See the ExpandBar in the SWT-Examples application. The page scrolling also scolles not a whole page.

Can you post a simple test case ?

I'm not sure what you mean by 'SWT-Examples application', is that the Control Example ?

Yes, it is the Control example (org.eclipse.swt.examples.controlexample.ExpandBarTab) which also demonstrates the problem.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
