Subject: Make glFieldButtonMenu multi-columned for large number of keys.
X-Git-Tag: glabels-2_3_0~154
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=1a23b8164c972458c3a434e892c6810939ac424b;p=glabels

Make glFieldButtonMenu multi-columned for large number of keys.

Make glFieldButtonMenu multi-columned for large number of keys.  I don't know
why, but I need to unrealize the old menu whenever reloading a new set of
keys -- otherwise, the new menu would not render properly.

Also, cleared the CAN_FOCUS and CAN_DEFAULT bits for the instance in
the object editor text edit page, so that it would not steal the focus
from the text editor.
