"""Desktop user interface surface base interface
An interface that may be implemented by a
:class:`~pywayland.protocol.wayland.WlSurface`, for implementations that
provide a desktop-style user interface.
It provides a base set of functionality required to construct user
interface elements requiring management by the compositor, such as toplevel
windows, menus, etc. The types of functionality are split into
:class:`XdgSurface` roles.
Creating an :class:`XdgSurface` does not set the role for a
:class:`~pywayland.protocol.wayland.WlSurface`. In order to map an
:class:`XdgSurface`, the client must create a role-specific object using,
e.g., get_toplevel, get_popup. The
:class:`~pywayland.protocol.wayland.WlSurface` for any given
:class:`XdgSurface` can have at most one role, and may not be assigned any
role not based on :class:`XdgSurface`.
A role must be assigned before any other requests are made to the
:class:`XdgSurface` object.
The client must call :func:`WlSurface.commit()
<pywayland.protocol.wayland.WlSurface.commit>` on the corresponding
:class:`~pywayland.protocol.wayland.WlSurface` for the :class:`XdgSurface`
state to take effect.
Creating an :class:`XdgSurface` from a
:class:`~pywayland.protocol.wayland.WlSurface` 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 :func:`XdgSurface.configure()` call
must also be treated as errors.
After creating a role-specific object and setting it up, the client must
perform an initial commit without any buffer attached. The compositor will
reply with an :func:`XdgSurface.configure()` event. The client must
acknowledge it and is then allowed to attach a buffer to map the surface.
Mapping an :class:`XdgSurface`-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 :class:`XdgSurface` to be mapped by the compositor, the following
conditions must be met: (1) the client has assigned an
:class:`XdgSurface`-based role to the surface (2) the client has set and
committed the :class:`XdgSurface` state and the role-dependent state to
the surface (3) the client has committed a buffer to the surface
A newly-unmapped surface is considered to have met condition (1) out of the
3 required conditions for mapping a surface if its role surface has not
been destroyed, i.e. the client must perform the initial commit again
before attaching a buffer.

"""Set the new window geometry
The window geometry of a surface is its "visible bounds" from the
user's perspective. Client-side decorations often have invisible
portions like drop-shadows which should be ignored for the purposes of
aligning, placing and constraining windows.
The window geometry is double buffered, and will be applied at the time
:func:`WlSurface.commit()
<pywayland.protocol.wayland.WlSurface.commit>` of the corresponding
:class:`~pywayland.protocol.wayland.WlSurface` is called.
When maintaining a position, the compositor should treat the (x, y)
coordinate of the window geometry as the top left corner of the window.
A client changing the (x, y) window geometry coordinate should in
general not alter the position of the window.
Once the window geometry of the surface is set, it is not possible to
unset it, and it will remain the same until set_window_geometry is
called again, even if a new subsurface or buffer is attached.
If never set, the value is the full bounds of the surface, including
any subsurfaces. This updates dynamically on every commit. This unset
is meant for extremely simple clients.
The arguments are given in the surface-local coordinate space of the
:class:`~pywayland.protocol.wayland.WlSurface` associated with this
:class:`XdgSurface`, and may extend outside of the
:class:`~pywayland.protocol.wayland.WlSurface` itself to mark parts of
the subsurface tree as part of the window geometry.
When applied, the effective window geometry will be the set window
geometry clamped to the bounding rectangle of the combined geometry of
the surface of the :class:`XdgSurface` and the associated subsurfaces.
The effective geometry will not be recalculated unless a new call to
set_window_geometry is done and the new pending surface state is
subsequently applied.
The width and height of the effective window geometry must be greater
than zero. Setting an invalid size will raise an invalid_size error.

"""Ack a configure event
When a configure event is received, if a client commits the surface in
response to the configure event, then the client must make an
ack_configure request sometime before the commit request, passing along
the serial of the configure event.
For instance, for toplevel surfaces the compositor might use this
information to move a surface to the top left only when the client has
drawn itself for the maximized or fullscreen state.
If the client receives multiple configure events before it can respond
to one, it only has to ack the last configure event. Acking a configure
event that was never sent raises an invalid_serial error.
A client is not required to commit immediately after sending an
ack_configure request - it may even ack_configure several times before
its next surface commit.
A client may send multiple ack_configure requests before committing,
but only the last request sent before a commit indicates which
configure event the client really is responding to.
Sending an ack_configure request consumes the serial number sent with
the request, as well as serial numbers sent by all configure events
sent on this :class:`XdgSurface` prior to the configure event
referenced by the committed serial.
It is an error to issue multiple ack_configure requests referencing a
serial from the same configure event, or to issue an ack_configure
request referencing a serial from a configure event issued before the
event identified by the last ack_configure request for the same
:class:`XdgSurface`. Doing so will raise an invalid_serial error.
