[GNC] GnuCash source code

[John Ralls]

Shashi,

Ultimately it’s called from https://gitlab.gnome.org/GNOME/glib/-/blame/main/gobject/gobject.c?ref_type=heads#L850, but if you’re looking for an explicit invocation of gnc_main_window_init you’re not going to find it. The COject creation macro G_DEFINE_TYPE_WITH_CODE  at https://github.com/Gnucash/gnucash/blob/555e23e8b5153eaa6decebdcf912a889c96e6328/gnucash/gnome-utils/gnc-main-window.cpp#L263 generates a structure of functions that includes a pointer to it. Note the parent class GTK_TYPE_APPLICATION_WINDOW in the macro call: that’s the next link in a chain that eventually ends with GObject and for initialization with _g_object_type_init. There’s actually another layer on top of that, GType, and _g_object_type_init is called from gtype.c in the same directory as gobject.c

This is early 1990’s object-oriented programming implemented with the C preprocessor instead of the compiler. If you’re comfortable with C++98 then you can study the GOject and Gtk tutorials and map it conceptually to C++. If not  https://wiki.gnucash.org/wiki/C++#Developer_Preparation provides some material you can study. 

Regards,
John Ralls
