Subject: Modified mode for the polyline. It is possible to change the polyline points.
X-Git-Tag: BR_hydro_v_0_3
X-Git-Url: http://git.salome-platform.org/gitweb/?a=commitdiff_plain;h=4e7f0692821fc25214c394b5df638bba2e672d22;p=modules%2Fhydro.git

Modified mode for the polyline. It is possible to change the polyline points.
ToDo:
- double editor for point coordinate
- restore selection after the value applying - IT IS DONE
- local selection only for section objects
- viewer comes to the widget constructor
