Subject: Multi-selection widget to be used in the extrusion feature.
X-Git-Tag: V_1.1.0~123
X-Git-Url: http://git.salome-platform.org/gitweb/?a=commitdiff_plain;h=6cb8b1b204d0ede5d98e6004bd1504f7758983ae;p=modules%2Fshaper.git

Multi-selection widget to be used in the extrusion feature.

It removes the cached mySelectedObject and myShape in the widget shape selector control.
