<description summary="create desktop-style surfaces">
This interface is implemented by servers that provide
desktop-style user interfaces.
It allows clients to associate a xdg_surface with
a basic surface.
xdg_shell allows clients to turn a wl_surface into a "real window"
which can be dragged, resized, stacked, and moved around by the
user. Everything about this interface is suited towards traditional
desktop environments.

On the server side the object is automatically destroyed when
the related wl_surface is destroyed. On client side,
xdg_surface.destroy() must be called before destroying
the wl_surface object.
The client must call wl_surface.commit on the corresponding wl_surface
for the xdg_surface state to take effect. Prior to committing the new
state, it can set up initial configuration, such as maximizing or setting
a window geometry.
Even without attaching a buffer the compositor must respond to initial
committed configuration, for instance sending a configure event with
expected window geometry if the client maximized its surface during
initialization.

The app ID identifies the general class of applications to which

It should be the ID that appears in the new desktop entry
specification, the interface name.
For D-Bus activatable applications, the app ID is used as the D-Bus
service name.
The compositor shell will try to group application surfaces together
by their app ID. As a best practice, it is suggested to select app
ID's that match the basename of the application's .desktop file.
For example, "org.freedesktop.FooViewer" where the .desktop file is
"org.freedesktop.FooViewer.desktop".
See the desktop-entry specification [0] for more details on
application identifiers and how they relate to well-known D-Bus
names and .desktop files.

For instance, the compositor might use this information to move

<interface name="xdg_popup" version="1">
<description summary="desktop-style metadata interface">
An interface that may be implemented by a wl_surface, for
implementations that provide a desktop-style popups/menus. A popup
surface is a transient surface with an added pointer grab.
<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.
An existing implicit grab will be changed to owner-events mode,
and the popup grab will continue after the implicit grab ends
(i.e. releasing the mouse button does not cause the popup to be
unmapped).
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.
The popup grab continues until the window is destroyed or a mouse
button is pressed in any other clients window. A click in any of
the clients surfaces is reported as normal, however, clicks in
other clients surfaces will be discarded and trigger the callback.
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.
The x and y arguments specify the locations of the upper left
corner of the surface relative to the upper left corner of the
parent surface, in surface local coordinates.
Clients that want to dismiss the popup when another surface of
their own is clicked should dismiss the popup using the destroy
request.
xdg_popup surfaces are always transient for another surface.
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. When a compositor dismisses
popups, it will follow the same dismissing order as required
from the client.
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_shell.get_xdg_popup.
The client must call wl_surface.commit on the corresponding wl_surface
for the xdg_popup state to take effect.
For a surface to be mapped by the compositor the client must have
committed both the xdg_popup state and a buffer.

<request name="destroy" type="destructor">
<description summary="remove xdg_surface interface">
The xdg_surface interface is removed from the wl_surface object
that was turned into a xdg_surface with
xdg_shell.get_xdg_surface request. The xdg_surface properties,
like maximized and fullscreen, are lost. The wl_surface loses
its role as a xdg_surface. The wl_surface is unmapped.
<description summary="remove xdg_popup interface">
This destroys the popup. Explicitly destroying the xdg_popup
object will also dismiss the popup, and unmap the surface.
If this xdg_popup is not the "topmost" popup, a protocol error
will be sent.

<event name="popup_done">
<description summary="popup interaction is done">
The popup_done event is sent out when a popup grab is broken,
that is, when the users clicks a surface that doesn't belong
to the client owning the popup surface.
The popup_done event is sent out when a popup is dismissed by the
compositor. The client should destroy the xdg_popup object at this
point.
