Menu.popupAtWidget
void popupAtWidget(gtk.widget.Widget widget, gdk.types.Gravity widgetAnchor, gdk.types.Gravity menuAnchor, gdk.event.Event triggerEvent = null)Displays menu and makes it available for selection.
See gtk_menu_popup_at_pointer () to pop up a menu at the master pointer. gtk_menu_popup_at_rect () also allows you to position a menu at an arbitrary rectangle.
menu will be positioned at widget, aligning their anchor points. widget_anchor and menu_anchor determine anchor points on widget and menu to pin together. menu can optionally be offset by #GtkMenu:rect-anchor-dx and #GtkMenu: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 #GtkMenu:anchor-hints and #GtkMenu:menu-type-hint. Connect to the #GtkMenu::popped-up signal to find out how it was actually positioned.
