Hi!
In a view i want to display a content, which might be larger than the
visible area of the view. I use a ScrolledComposite which has the method
setMinSize() where you can set the minimal Size at which Scrollbars
should be shown. The only way i see is to giveMinSize the dimension of
the view.
Is there some way to get the current dimension of a view?
Thanks in advance.

Thanks for your reply Veronika, but seems it doesn`t work correct in my
case. I am developing an eclipse plugin, my content is created
dymnamicly and after that, i want to decide if scrollbars are needed.
The composite which represents the content, includes other composites.
When i try to use something like
sc2.setMinSize(c2.computeSize(SWT.DEFAULT, SWT.DEFAULT));
the whole content is displayed, but now scrollbars are shown. I could
see my the content which is to large for the visible area, when resize
the view.
Is it possible that a view has a different behavior in this case then a
normal window?
If i use getClientArea() on a composite in my view, i get the visible
area of the view. I tried to use setSize on my ScrolledComposite and
then use setMinSize(), but i doesen't seems to work, too.
Any idea?

Views work the same as any other SWT Composite. Please give a code example
showing your problem.

OK i figured it out, in my code was missing:
viewComposite.setLayoutData(new GridData(GridData.FILL_VERTICAL));
which seems to be necessary.
