[STR Closed w/Resolution]
Link: http://www.fltk.org/str.php?L1784
Version: 2.0-current
Fix Version: 2.0-current
Ben, I can reproduce it, please see the attached modified file scroll2.cxx
for better visibility of the RED labels. The problem manifests only with
*outside* labels.
I marked two comments with "***" to show what I changed (additionally to a
vertical offset of 20 pixels to show the top outside labels as well), and
the 2nd comment shows a workaround by explicitly adding an invisible box
at (0,0).
I didn't change the STR status though, leaving it up to you to reopen it
or close with "won't fix", maybe. I believe that this effect is also in
FLTK 1.x, but I didn't check (yet).
(1) Reproduced with svn r8635 (before XP theme updates), shows the
described effect.
(2) Reproduced with current svn (with XP theme) as well, but (maybe OT
here?): where are all the button colors gone?
