of course not. Just to illustrate what I really want as it (before the
window needs any redrawing) looks like what I want ;)

setEnabled() isn't exactly described in the APIDoc. There's just written
that you can't click on a Button which is setEnabled(false)
 
I don't think this is a bug. It would rather be a feature request as
setEnabled(false) does not yet do anything with a progressbar. But I think
this wouldn't be a really clever function to place there because it
_only_ is for ProgressBar with SWT.INDETERMINATE and not for the rest

no, definitely not. 

It looks like the easiest way is for me to use the Bar _without_
SWT.INDETERMINATE and to make it move with an own thread which is easily
stoppable
