I am not sure if there are different signals for catching minimize and
maximize event states. According to the comments in gtkwindow.c file, we
can track iconification/maximization through "window_state_event" signal
only.

Guess, you can try using gdk_window_get_state(), which will return
window state bitfield. For example,

        GdkWindowState state;
        if (widget->window) {
                state = gdk_window_get_state (widget->window);
                if (state & GDK_WINDOW_STATE_ICONIFIED) {
                        //Window is in iconified state.
                }
        }
                
Thanks,
Narayana
