FlowLayout & zoom issues [message #178172]

When using a figure with FlowLayout and FlowLayoutEditPolicy I see different
"layouting" behaviors depending on the currently selected zoom factor. The
content of my editor is set as:

Figure f = new Figure();
f.setBorder(new MarginBorder(5));
f.setLayoutManager(new FlowLayout());

Take a look at the attached pictures. I'm changing the size of the editor
window and never get vertical arrangement of my boxes at 100% zoom.
Everything works perfect on 75% and 150% and others. There is also something
fishy about the scrollbar (see the second picture at 75% zoom) - it still
thinks that boxes are arranged horizontally.

I haven't found any material on the matter.
Where to dig?

Yes, just noticed: vertical arrangement does not happen at
100%,200%,300%,400% zoom. Other factors do work.

This is sort of an inconsistency. I think that hints are not used when the
scrollbar calculation is made, but then hints are used later.

You should be using viewport.setContentsTracksWidth(true), since that is how
flowlayout works.

Thanx, Randy!

viewport.setContentsTracksWidth(true) solved my problem completely for 100%
zoom.
And now one can see clearly what does not work: the calculation of the
scrollbars does not take zoom factor into account at all.

I'm not sure that's the exact problem, but could you open a bugzilla with
details of the figure structure needed to reproduce?
