I use libvlc_media_player_set_hwnd() function in GTK# (Xamarin). But I can't get a HWND of GTK# widget and set it in libvlc_media_player_set_hwnd() function. In GTK+ I can use gdk_x11_drawable_get_xid(), but I haven't found this function in GTK#.
So how I can get a HWND of widgets or use this function for output media in the needed window/container/widget?
