Hi,
I have several composite figures that are managed by a ToolbarLayout
(vertical).
They hold two Label figures and a shape. When the compound figure is
created with a given bounds size or when the user resizes the figure I
want the shape to occupy all available space.
However I did not find an easy way to calculate this. What I do now is
to first set the font of the labels and then calculate their preferred
sizes, subtract them together with layout spacing from the overall
height of the compound figure. This meachanism doesn't really work well.
When the figure is created first it draws a few pixel to large. However
when I move it around it suddenly draws correctly.
What is your advice? Should I write my own LayoutManager?
thanks,
Torsten.

No, I didn't. I just asked if I should.
But the problem seems to disappear when I properly set the font of the
two labels involved in the figure.
