[news.eclipse.platform.swt] Re: Mouse scroll leads to different event ra

["Grant Gayed" <grant_gayed@xxxxxxxxxx>]

Just to confirm, your table is custom-built (for example, you're drawing
everything on a Canvas), and you have added a Selection listener to its
scrollbar in order to see its detail field, right?  If so, yout table must
be listening for SWT.MouseWheel events in order to know when to scroll.  Do
you see a platform difference when these events comes in?

If I am not understanding correctly then you will need to clarify.  If
possible, the best clarification is a code snippet that demonstrates the
problem (snippet template:
