Menu.popupAtRect

void popupAtRect(gdk.window.Window rectWindow,  gdk.rectangle.Rectangle rect,  gdk.types.Gravity rectAnchor,  gdk.types.Gravity menuAnchor,  gdk.event.Event triggerEvent =  null)

Displays menu and makes it available for selection.

See gtk_menu_popup_at_widget () and gtk_menu_popup_at_pointer (), which handle more common cases for popping up menus.

menu 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 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.
