c++ - wxWidgets: How to adjust size of indent of wxDataViewCtrl? -

i using gtk port of wxwidgets 3.0.2.

i have wxdataviewctrl displaying it's data model in tree-like fashion. possible make size of how child nodes indented underneath parent node bigger?

i know there's wxdataviewctrl::setindent() method, doesn't seem anything. indeed, when @ source code setindent(), calls out dosetindent() method , gtk, method no-op :-(.

currently impossible, seems simple using gtk_tree_view_set_level_indentation(), i've done this , setindent() work in wxwidgets 3.1.0 released soon.

in meanwhile, can same thing in own code using wxwindow::gethandle() retrieve gtktreeview widget control.
