Hi,
just had these two problems with a BBox:
1) I added a menu field as a label for a BBox and a layout to the BBox. In
this case in DoLayout *) the label view is removed, BView::DoLayout called
and the label is added again. The comment says this is because the label
should not be layouted. The problem is that AddChild triggers a relayout
which results in an infinite loop.
My first solution is to just leave the label added to the BBox while
calling BView::DoLayout and just move it back to the right position
afterwards. This works fine but why BView::DoLayout layouts the label view
at all? I mean the label is not part of any layout class so it should be
ignored or what is the policy here?
2) When setting a layout to a BBox its a bit annoying to set the correct
layout inset so that the content is exactly within the inner BBox frame.
It would be nice to have some convenient function to set the inset to the
layout. Or even better: the layout of a BBox is moved automatically into
the inner frame so that it is not event possible to place a layout item
outside the inner frame. What do you think?
Cheers,
Clemens
