No, you're looking closely enough. 

FWIW, this is how LyX goes about showing an iconified window.

HTH,
Angus

	if (form()->visible) {
		fl_raise_form(form());
		/* This XMapWindow() will hopefully ensure that
		 * iconified dialogs are de-iconified. Mad props
		 * out to those crazy Xlib guys for forgetting a
		 * XDeiconifyWindow(). At least WindowMaker, when
		 * being notified of the redirected MapRequest will
		 * specifically de-iconify. From source, fvwm2 seems
		 * to do the same.

		XMapWindow(fl_get_display(), form()->window);
	} else {
		// calls to fl_set_form_minsize/maxsize apply only to the next
		// fl_show_form(), so this comes first.
		fl_set_form_minsize(form(), minw_, minh_);
		if (!allow_resize_)
			fl_set_form_maxsize(form(), minw_, minh_);

		string const maximize_title = "LyX: " + title_;
		int const iconify_policy =
			getController().IconifyWithMain() ? FL_TRANSIENT : 0;

		fl_show_form(form(),
			     FL_PLACE_MOUSE | FL_FREE_SIZE,
			     iconify_policy,
			     maximize_title.c_str());
	}
