code: func (v *Menu) PopupAtStatusIcon(statusIcon *StatusIcon, button uint, activateTime uint32) {
  	C.gotk_menu_popup_at_status_icon(v.native(), statusIcon.native(), C.guint(button), C.guint32(activateTime))
  }
docs: // PopupAtStatusIcon() is a wrapper around gtk_menu_popup() specific to usage with GtkStatusIcon.
  // gomenu_popup() is defined in menu.go.h, this is a workaround to pass gtk_status_icon_position_menu as the GtkMenuPositionFunc.
