The variables tableColumn and item are unneeded in this class so remove them. Use static_cast<>s instead of C casts. Avoid repeating oneVeryLongVariableName->anotherEvenLongerVariableName-> somethingElse->andSoOn multiple times, temporary variables are allowed in C++. Also don't call wxDataViewCustomRenderer::GetSize() twice unnecessarily. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@62389 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
