This is the wrong list (it's about the development of GTK itself); 
you want gtk-app-devel (which is about working on GTK applications).

Sort of, but with type checking. It's not a straight cast; it's a 
macro defined in glib-2.0/gobject.h.

No. In a regular C cast you can't put the parentheses around the 
variable name.
