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.

viewComposite = new ScrolledComposite(parent, SWT.V_SCROLL | SWT.H_SCROLL );
viewComposite.setExpandHorizontal(true);
viewComposite.setExpandVertical(true);
commandComposite = new Composite (viewComposite,SWT.NONE);
commandComposite.setLayout(new GridLayout(1, false));
commandComposite.setLayoutData(new GridData());
viewComposite.setContent(commandComposite);
//dynamic add composites to commandComposite
//...
viewComposite.setMinSize(commandComposite.computeSize(SWT.DE FAULT,
SWT.DEFAULT));
// i tried this, but it seems to have no effect
//viewComposite.setSize(viewComposite.getClientArea().width, viewComposite.getClientArea().height);
commandComposite.layout(true);
viewComposite.layout(true);
parent.layout(true);

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