+ <interface name="xdg_popup" version="1">
+ <description summary="short-lived, popup surfaces for menus">
+ A popup surface is a short-lived, temporary surface that can be
+ used to implement menus. It takes an explicit grab on the surface
+ that will be dismissed when the user dismisses the popup. This can
+ be done by the user clicking outside the surface, using the keyboard,
+ or even locking the screen through closing the lid or a timeout.
+
+ When the popup is dismissed, a popup_done event will be sent out,
+ and at the same time the surface will be unmapped. The xdg_popup
+ object is now inert and cannot be reactivated, so clients should
+ destroy it. Explicitly destroying the xdg_popup object will also
+ dismiss the popup and unmap the surface.
+
+ Clients will receive events for all their surfaces during this
+ grab (which is an "owner-events" grab in X11 parlance). This is
+ done so that users can navigate through submenus and other
+ "nested" popup windows without having to dismiss the topmost
+ popup.
+
+ Clients that want to dismiss the popup when another surface of
+ their own is clicked should dismiss the popup using the destroy
+ request.
+
+ The parent surface must have either an xdg_surface or xdg_popup
+ role.
+
+ Specifying an xdg_popup for the parent means that the popups are
+ nested, with this popup now being the topmost popup. Nested
+ popups must be destroyed in the reverse order they were created
+ in, e.g. the only popup you are allowed to destroy at all times
+ is the topmost one.
+
+ If there is an existing popup when creating a new popup, the
+ parent must be the current topmost popup.
+
+ A parent surface must be mapped before the new popup is mapped.
+
+ When compositors choose to dismiss a popup, they will likely
+ dismiss every nested popup as well.
+
+ The x and y arguments specify where the top left of the popup
+ should be placed, relative to the local surface coordinates of the
+ parent surface.
