- Requests that the compositor avoids occluding an area of the surface
- with other surfaces. The compositor's use of this information is
- implementation-dependent - do not assume that this region will not
- actually be occluded.
-
- A positive value is only meaningful if the surface is anchored to an
- edge, rather than a corner. The zone is the number of surface-local
- coordinates from the edge that is considered exclusive.
-
- Surfaces that do not wish to have an exclusive zone may instead specify
- how they should interact with surfaces that do. If set to zero, the
- surface indicates that it would like to be moved to avoid occluding
- surfaces with a positive exclusive zone. If set to -1, the surface
- indicates that it would not like to be moved to accommodate for other
- surfaces, and the compositor should extend it all the way to the edges
- it is anchored to.
-
- For example, a panel might set its exclusive zone to 10, so that
- maximized shell surfaces are not shown on top of it. A notification
- might set its exclusive zone to 0, so that it is moved to avoid
- occluding the panel, but shell surfaces are shown underneath it. A
- wallpaper or lock screen might set their exclusive zone to -1, so that
- they stretch below or over the panel.

- xdg_surface roles.
-
- Creating an xdg_surface does not set the role for a wl_surface. In order
- to map an xdg_surface, the client must create a role-specific object
- using, e.g., get_toplevel, get_popup. The wl_surface for any given
- xdg_surface can have at most one role, and may not be assigned any role
- not based on xdg_surface.
-
- A role must be assigned before any other requests are made to the
- xdg_surface object.
-
- The client must call wl_surface.commit on the corresponding wl_surface
- for the xdg_surface state to take effect.
-
- Creating an xdg_surface from a wl_surface which has a buffer attached or
- committed is a client error, and any attempts by a client to attach or
- manipulate a buffer prior to the first xdg_surface.configure call must
- also be treated as errors.
-
- Mapping an xdg_surface-based role surface is defined as making it
- possible for the surface to be shown by the compositor. Note that
- a mapped surface is not guaranteed to be visible once it is mapped.
-
- For an xdg_surface to be mapped by the compositor, the following
- conditions must be met:
- (1) the client has assigned an xdg_surface-based role to the surface
- (2) the client has set and committed the xdg_surface state and the
- role-dependent state to the surface
- (3) the client has committed a buffer to the surface

-
- Requesting a minimum size to be larger than the maximum size of
- a surface is illegal and will result in a protocol error.
-
- The width and height must be greater than or equal to zero. Using

-
- It is up to the compositor to decide how and where to maximize the

-
- If the surface was already maximized, the compositor will still emit

- un-maximizes the window is subject to compositor policies.
- If available and applicable, the compositor will include the window
- geometry dimensions the window had prior to being maximized in the

- client is actually put into a fullscreen state is subject to compositor
- policies. The client must also acknowledge the configure when
- committing the new content (see ack_configure).
-
- The output passed by the request indicates the client's preference as
- to which display it should be set fullscreen on. If this value is NULL,
- it's up to the compositor to choose which display will be used to map
- this surface.
-
- If the surface doesn't cover the whole output, the compositor will
- position the surface in the center of the output and compensate with
- with border fill covering the rest of the output. The content of the
- border fill is undefined, but should be assumed to be in some way that
- attempts to blend into the surrounding area (e.g. solid black).
-
- If the fullscreened surface is not opaque, the compositor must make
- sure that other screen content not part of the same surface tree (made
- up of subsurfaces, popups or similarly coupled surfaces) are not
- visible below the fullscreened surface.

- Making a surface unfullscreen sets states for the surface based on the following:
- * the state(s) it may have had before becoming fullscreen

- about how its surface should be resized in window geometry

-
- If the width or height arguments are zero, it means the client
- should decide its own window dimension. This may happen when the

-
- The states listed in the event specify how the width/height

- <description summary="short-lived, popup surfaces for menus">
- A popup surface is a short-lived, temporary surface. It can be used to
- implement for example menus, popovers, tooltips and other similar user
- interface concepts.
-
- A popup can be made to take an explicit grab. See xdg_popup.grab for
- details.
-
- When the popup is dismissed, a popup_done event will be sent out, and at
- the same time the surface will be unmapped. See the xdg_popup.popup_done
- event for details.
-
- Explicitly destroying the xdg_popup object will also dismiss the popup and
- unmap the surface. Clients that want to dismiss the popup when another
- surface of their own is clicked should dismiss the popup using the destroy
- request.
-
- A newly created xdg_popup will be stacked on top of all previously created
- xdg_popup surfaces associated with the same xdg_toplevel.
-
- The parent of an xdg_popup must be mapped (see the xdg_surface
- description) before the xdg_popup itself.
-
- The x and y arguments passed when creating the popup object specify
- where the top left of the popup should be placed, relative to the
- local surface coordinates of the parent surface. See
- xdg_surface.get_popup. An xdg_popup must intersect with or be at least
- partially adjacent to its parent surface.
-
- The client must call wl_surface.commit on the corresponding wl_surface
- for the xdg_popup state to take effect.

- <description summary="make the popup take an explicit grab">
- This request makes the created popup take an explicit grab. An explicit
- grab will be dismissed when the user dismisses the popup, or when the
- client destroys the xdg_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.
-
- If the compositor denies the grab, the popup will be immediately
- dismissed.
-
- This request must be used in response to some sort of user action like a
- button press, key press, or touch down event. The serial number of the
- event should be passed as 'serial'.
-
- The parent of a grabbing popup must either be an xdg_toplevel surface or
- another xdg_popup with an explicit grab. If the parent is another
- 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.
