Subject: Add wxDataViewRendererBase::PrepareForItem() helper.
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/f0ccd2cbfa0b4ac110b81626da5a184b650b1080?ds=inline

Add wxDataViewRendererBase::PrepareForItem() helper.

For calling SetValue() and SetAttr() consistently, instead of having the
same code duplicated all over the place.

git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@65950 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
