See gtk_menu_popup_at_widget () and gtk_menu_popup_at_pointer (), which handle more common cases for popping up menus.
this will be positioned at rect, aligning their anchor points. rect is relative to
the top-left corner of rect_window. rect_anchor and menu_anchor determine anchor points on rect
and this to pin together. this can optionally be offset by
rect_anchor_dx and
rect_anchor_dy.
Anchors should be specified under the assumption that the text direction is left-to-right; they will be flipped horizontally automatically if the text direction is right-to-left.
Other properties that influence the behaviour of this function are anchor_hints and menu_type_hint. Connect to the popped_up signal to find out how it was actually positioned.
