Subject: wxDataViewCtrl::Expand() only works on items whose parents are already
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/e3d358bbe4940c85304e9193010b27ba04c9fb86

wxDataViewCtrl::Expand() only works on items whose parents are already
 expanded. The attached patch fixes this by expanding all ancestors of the
 item before expanding the item itself. Closes #12585: wxDataviewCtrl::Expand() needs to expand all ancestors
