Subject: For all libSalomePy methods provide "toCreate" parameter (with default value 0) ... 
X-Git-Tag: V3_2_3pre1~13
X-Git-Url: http://git.salome-platform.org/gitweb/?a=commitdiff_plain;h=e66c20243a6cbf888eedb1c3594349fb9c35f7fe;p=modules%2Fgui.git

For all libSalomePy methods provide "toCreate" parameter (with default value 0) - if this parameter is not 0, the new VTK window is always created. If this parameter is 0, new VTK window is created only if there is no existing one.
