popup_at_widget
Description:
public void popup_at_widget (Widget widget, Gravity widget_anchor, Gravity menu_anchor, Event? trigger_event = null)
Displays this 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.
this will be positioned at widget, aligning their anchor points. widget_anchor and
menu_anchor determine anchor points on widget 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.
