Subject: delete default layout in MotifEditor
X-Git-Url: http://woldlab.caltech.edu/gitweb/?p=mussa.git;a=commitdiff_plain;h=4b9dd885cdfef6d73c82bae5f112a063588766a9

delete default layout in MotifEditor
Qt was generating warning messages about couldn't set layout
on the MotifEditor while one was already set. It turns out you
need to delete the default layout before calling setLayout().
