Subject: [NEW] Add the volumic gradation parameter.
X-Git-Tag: V6_6_0a1~5
X-Git-Url: http://git.salome-platform.org/gitweb/?a=commitdiff_plain;h=93bc8657b3f771b58fc71ff385f759db580df8fe;p=plugins%2Fhybridplugin.git

[NEW] Add the volumic gradation parameter.
[FIX] In GUI, replace myEnforcedTableWidget->clear() by myEnforcedTableWidget->clearContents() (header labels were erased)
