Detailed Description

       create desktop-style surfaces

       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.

Member Function Documentation

std::stringwayland::server::resource_t::get_class()[inherited]
Retrieve the interface name (class) of a resource object.

Returns
Interface name of the resource object.

client_twayland::server::resource_t::get_client()const[inherited]
Get the associated client

Returns
the client that owns the resource.

uint32_twayland::server::resource_t::get_id()const[inherited]
Get the internal ID of the resource

Returns
the internal ID of the resource

unsignedintwayland::server::resource_t::get_version()const[inherited]
Get interface version

Returns
Interface version this resource has been constructed with.

std::function<void(zxdg_positioner_v6_t)>&zxdg_shell_v6_t::on_create_positioner()
create a positioner object

Parametersid

Create a positioner object. A positioner object is used to position surfaces relative to some parent
surface. See the interface description and xdg_surface.get_popup for details.

Definition at line 8191 of file wayland-server-protocol-unstable.cpp.

std::function<void()>&zxdg_shell_v6_t::on_destroy()
destroy xdg_shell Destroy this xdg_shell object.

Destroying a bound xdg_shell object while there are surfaces still alive created by this xdg_shell object
instance is illegal and will result in a protocol error.

Definition at line 8185 of file wayland-server-protocol-unstable.cpp.

std::function<void(zxdg_surface_v6_t,surface_t)>&zxdg_shell_v6_t::on_get_xdg_surface()
create a shell surface from a surface

Parametersidsurface

This creates an xdg_surface for the given surface. While xdg_surface itself is not a role, the
corresponding surface may only be assigned a role extending xdg_surface, such as xdg_toplevel or
xdg_popup.

This creates an xdg_surface for the given surface. An xdg_surface is used as basis to define a role to a
given surface, such as xdg_toplevel or xdg_popup. It also manages functionality shared between
xdg_surface based surface roles.

See the documentation of xdg_surface for more details about what an xdg_surface is and how it is used.

std::function<void(uint32_t)>&zxdg_shell_v6_t::on_pong()
respond to a ping event

Parametersserial serial of the ping event

A client must respond to a ping event with a pong request or the client may be deemed unresponsive. See
xdg_shell.ping.

Definition at line 8203 of file wayland-server-protocol-unstable.cpp.

voidzxdg_shell_v6_t::ping(uint32_tserial,boolpost=true)
check if the client is alive

Parametersserial pass this to the pong request

The ping event asks the client if it's still alive. Pass the serial specified in the event back to the
compositor by sending a 'pong' request back with the specified serial. See xdg_shell.ping.

Compositors can use this to determine if the client is still alive. It's unspecified what will happen if
the client doesn't respond to the ping request, or in what timeframe. Clients should try to respond in a
reasonable amount of time.

A compositor is free to ping in any way it wants, but a client must always respond to any xdg_shell
object it created.

voidzxdg_shell_v6_t::post_invalid_popup_parent(std::stringconst&msg)
Post error: the client specified an invalid popup parent surface.

voidwayland::server::resource_t::post_no_memory()const[inherited]
Post 'not enough memory' error to the client

If the compositor has not enough memory to fulfill a certail request of the client, this function can be
called to notify the client of this circumstance.

voidzxdg_shell_v6_t::post_not_the_topmost_popup(std::stringconst&msg)
Post error: the client tried to map or destroy a non-topmost popup.

Definition at line 8224 of file wayland-server-protocol-unstable.cpp.

voidzxdg_shell_v6_t::post_role(std::stringconst&msg)
Post error: given wl_surface has another role.

Definition at line 8214 of file wayland-server-protocol-unstable.cpp.

boolwayland::server::resource_t::proxy_has_object()const[inherited]
Check whether this wrapper actually wraps an object.

Returns
true if there is an underlying object, false if this wrapper is empty
