I'm following this tutorial here: http://sfml-dev.org/tutorials/1.6/graphics-wxwidgets.php
My first problem is GTK_PIZZA (what on earth does that even mean?). It's undefined, and apparently has been obsolete since wx-2.8 (I'm using wx-3.0). My second problem is that m_wxwindow is NULL, and so is the value returned by GetHandle().
So how do I get the window handle/X11 identifier of the window to pass to sf::RenderWindow::create()?
