+
+ The server may ignore resize requests depending on the state of
+ the surface (e.g. fullscreen or maximized).
+
+ If triggered, the client will receive configure events with the
+ "resize" state enum value and the expected sizes. See the "resize"
+ enum value for more details about what is required. The client
+ must also acknowledge configure events using "ack_configure". After
+ the resize is completed, the client will receive another "configure"
+ event without the resize state.
+
+ If triggered, the surface also will lose the focus of the device
+ (wl_pointer, wl_touch, etc) used for the resize. It is up to the
+ compositor to visually indicate that the resize is taking place,
+ such as updating a pointer cursor, during the resize. There is no
+ guarantee that the device focus will return when the resize is
+ completed.
+
+ The edges parameter specifies how the surface should be resized,
+ and is one of the values of the resize_edge enum. The compositor
+ may use this information to update the surface position for
+ example when dragging the top left corner. The compositor may also
+ use this information to adapt its behavior, e.g. choose an
+ appropriate cursor image.

+ outside the surface, using the keyboard, or even locking the screen

+

+ xdg_popup it 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.
+
+ When compositors choose to dismiss a popup, they may dismiss every
+ nested grabbing popup as well. When a compositor dismisses popups, it
+ will follow the same dismissing order as required from the client.
+
+ The parent of a grabbing popup must either be another xdg_popup with an
+ active explicit grab, or an xdg_popup or xdg_toplevel, if there are no
+ explicit grabs already taken.
+
+ If the topmost grabbing popup is destroyed, the grab will be returned to
+ the parent of the popup, if that parent previously had an explicit grab.
+
+ If the parent is a grabbing popup which has already been dismissed, this
+ popup will be immediately dismissed. If the parent is a popup that did
+ not take an explicit grab, an error will be raised.
+
+ During a popup grab, the client owning the grab will receive pointer
+ and touch events for all their surfaces as normal (similar to an
+ "owner-events" grab in X11 parlance), while the top most grabbing popup
+ will always have keyboard focus.
