The original code (see r66404 and r66416) didn't work because it used wxDataViewRenderer::SetMode() to make the renderer inactive but then used its GetMode() to restore the previous state -- which was lost. The result of this was that if the overridden IsEnabled() in the model ever returned false for any row, all the cells in this column, in all the rows, became insensitive, as could be seen by the inability to edit any rating in the first page of the dataview sample (even though it was disabled for a single row only) and any checkboxes on its third page (even though only the last two of them were supposed to be disabled). Fix this simply by making the renderer insensitive at GTK level only, but do not change the mode at wx level. See #12686. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@78470 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
