I think the idea of using "call gtk_main_iteration() in a while loop

Have started building the 3.20 bindings for Nim language...
Currently we are not using GObject Introspection but generate the
bindings from the header files using the Nim tool c2nim.

The header bar contains a GtkStackSwitcher, which is a standalone
