19 <description summary="Server side window decoration manager">
20 This interface allows to coordinate whether the server should create
21 a server-side window decoration around a wl_surface representing a
22 shell surface (wl_shell_surface or similar). By announcing support
23 for this interface the server indicates that it supports server
24 side decorations.
25 </description>
26 <request name="create">
27 <description summary="Create a server-side decoration object for a given surface">
28 When a client creates a server-side decoration object it indicates
29 that it supports the protocol. The client is supposed to tell the
30 server whether it wants server-side decorations or will provide
31 client-side decorations.
32
33 If the client does not create a server-side decoration object for
34 a surface the server interprets this as lack of support for this
35 protocol and considers it as client-side decorated. Nevertheless a
36 client-side decorated surface should use this protocol to indicate
37 to the server that it does not want a server-side deco.

50 This event is emitted directly after binding the interface. It contains

53 request_mode is requested.

75 <description summary="The new decoration mode applied by the server">
76 This event is emitted directly after the decoration is created and
77 represents the base decoration policy by the server. E.g. a server
78 which wants all surfaces to be client-side decorated will send Client,
79 a server which wants server-side decoration will send Server.
80
81 The client can request a different mode through the decoration request.
82 The server will acknowledge this by another event with the same mode. So
83 even if a server prefers server-side decoration it's possible to force a
84 client-side decoration.
85
86 The server may emit this event at any time. In this case the client can
87 again request a different mode. It's the responsibility of the server to
88 prevent a feedback loop.
