*
|

* @section intro_sec Introduction
|
||||
* TinyCThread is a minimal, portable implementation of basic threading
|
||||
* classes for C.
|
||||
*
|
||||
* They closely mimic the functionality and naming of the C11 standard, and
|
||||
* should be easily replaceable with the corresponding standard variants.
|
||||
*
|
||||
* @section port_sec Portability
|
||||
* The Win32 variant uses the native Win32 API for implementing the thread
|
||||
* classes, while for other systems, the POSIX threads API (pthread) is used.
|
||||
*
|
||||
* @section misc_sec Miscellaneous
|
||||
* The following special keywords are available: #_Thread_local.
|
||||
*
|
||||
* For more detailed information, browse the different sections of this
|
||||
* documentation. A good place to start is:
|

* tinycthread.h.

<description summary="Protocol for requesting fractional surface scales">
|
||||
This protocol allows a compositor to suggest for surfaces to render at
|
||||
fractional scales.
|
||||
|
||||
A client can submit scaled content by utilizing wp_viewport. This is done by
|
||||
creating a wp_viewport object for the surface and setting the destination
|
||||
rectangle to the surface size before the scale factor is applied.
|
||||
|
||||
The buffer size is calculated by multiplying the surface size by the
|
||||
intended scale.
|
||||
|
||||
The wl_surface buffer scale should remain set to 1.
|
||||
|
||||
If a surface has a surface-local size of 100 px by 50 px and wishes to
|
||||
submit buffers with a scale of 1.5, then a buffer of 150px by 75 px should
|
||||
be used and the wp_viewport destination rectangle should be 100 px by 50 px.
|
||||
|
||||
For toplevel surfaces, the size is rounded halfway away from zero. The
|
||||
rounding algorithm for subsurface position and size is not defined.

<description summary="protocol for constraining pointer motions">
|
||||
This protocol specifies a set of interfaces used for adding constraints to
|
||||
the motion of a pointer. Possible constraints include confining pointer
|
||||
motions to a given region, or locking it to its current position.
|
||||
|
||||
In order to constrain the pointer, a client must first bind the global
|
||||
interface "wp_pointer_constraints" which, if a compositor supports pointer
|
||||
constraints, is exposed by the registry. Using the bound global object, the
|
||||
client uses the request that corresponds to the type of constraint it wants
|
||||
to make. See wp_pointer_constraints for more details.
|
||||
|
||||
Warning! The protocol described in this file is experimental and backward
|
||||
incompatible changes may be made. Backward compatible changes may be added
|
||||
together with the corresponding interface version bump. Backward
|
||||
incompatible changes are done by bumping the version number in the protocol
|
||||
and interface names and resetting the interface version. Once the protocol
|
||||
is to be declared stable, the 'z' prefix and the version number in the
|
||||
protocol and interface names are removed and the interface version number is
|
||||
reset.

<description summary="constrain the movement of a pointer">
|

The global interface exposing pointer constraining functionality. It
|
||||
exposes two requests: lock_pointer for locking the pointer to its
|
||||
position, and confine_pointer for locking the pointer to a region.
|
||||
|
||||
The lock_pointer and confine_pointer requests create the objects
|
||||
wp_locked_pointer and wp_confined_pointer respectively, and the client can
|
||||
use these objects to interact with the lock.
|
||||
|
||||
For any surface, only one lock or confinement may be active across all
|
||||
wl_pointer objects of the same seat. If a lock or confinement is requested
|
||||
when another lock or confinement is active or requested on the same surface
|

<request name="lock_pointer">
|

<description summary="lock pointer to a position">
|
||||
The lock_pointer request lets the client request to disable movements of
|
||||
the virtual pointer (i.e. the cursor), effectively locking the pointer
|
||||
to a position. This request may not take effect immediately; in the
|
||||
future, when the compositor deems implementation-specific constraints
|
||||
are satisfied, the pointer lock will be activated and the compositor
|
||||
sends a locked event.
|
||||
|
||||
The protocol provides no guarantee that the constraints are ever
|
||||
satisfied, and does not require the compositor to send an error if the
|
||||
constraints cannot ever be satisfied. It is thus possible to request a
|
||||
lock that will never activate.
|
||||
|
||||
There may not be another pointer constraint of any kind requested or
|
||||
active on the surface for any of the wl_pointer objects of the seat of
|
||||
the passed pointer when requesting a lock. If there is, an error will be
|
||||
raised. See general pointer lock documentation for more details.
|
||||
|
||||
The intersection of the region passed with this request and the input
|
||||
region of the surface is used to determine where the pointer must be
|
||||
in order for the lock to activate. It is up to the compositor whether to
|
||||
warp the pointer or require some kind of user interaction for the lock
|
||||
to activate. If the region is null the surface input region is used.
|
||||
|
||||
A surface may receive pointer focus without the lock being activated.
|
||||
|
||||
The request creates a new object wp_locked_pointer which is used to
|
||||
interact with the lock as well as receive updates about its state. See
|
||||
the the description of wp_locked_pointer for further information.
|
||||
|
||||
Note that while a pointer is locked, the wl_pointer objects of the
|
||||
corresponding seat will not emit any wl_pointer.motion events, but
|
||||
relative motion events will still be emitted via wp_relative_pointer
|
||||
objects of the same seat. wl_pointer.axis and wl_pointer.button events
|
||||
are unaffected.

||||
This object will send the event 'confined' when the confinement is
|
||||
activated. Whenever the confinement is activated, it is guaranteed that
|
||||
the surface the pointer is confined to will already have received pointer
|
||||
focus and that the pointer will be within the region passed to the request
|
||||
creating this object. It is up to the compositor to decide whether this
|
||||
requires some user interaction and if the pointer will warp to within the
|
||||
passed region if outside.
|
||||
|
||||
To unconfine the pointer, send the destroy request. This will also destroy
|
||||
the wp_confined_pointer object.
|
||||
|
||||
If the compositor decides to unconfine the pointer the unconfined event is
|
||||
sent. The wp_confined_pointer object is at this point defunct and should
|
||||
be destroyed.

<description summary="protocol for relative pointer motion events">
|
||||
This protocol specifies a set of interfaces used for making clients able to
|
||||
receive relative pointer events not obstructed by barriers (such as the
|
||||
monitor edge or other pointer barriers).
|
||||
|
||||
To start receiving relative pointer events, a client must first bind the
|
||||
global interface "wp_relative_pointer_manager" which, if a compositor
|
||||
supports relative pointer motion events, is exposed by the registry. After
|
||||
having created the relative pointer manager proxy object, the client uses
|
||||
it to create the actual relative pointer object using the
|
||||
"get_relative_pointer" request given a wl_pointer. The relative pointer
|
||||
motion events will then, when applicable, be transmitted via the proxy of
|
||||
the newly created relative pointer object. See the documentation of the
|
||||
relative pointer interface for more details.
|
||||
|
||||
Warning! The protocol described in this file is experimental and backward
|
||||
incompatible changes may be made. Backward compatible changes may be added
|
||||
together with the corresponding interface version bump. Backward
|
||||
incompatible changes are done by bumping the version number in the protocol
|
||||
and interface names and resetting the interface version. Once the protocol
|
||||
is to be declared stable, the 'z' prefix and the version number in the
|
||||
protocol and interface names are removed and the interface version number is
|
||||
reset.

Relative x/y pointer motion from the pointer of the seat associated with

this object.
|
||||
|
||||
A relative motion is in the same dimension as regular wl_pointer motion
|
||||
events, except they do not represent an absolute position. For example,
|
||||
moving a pointer from (x, y) to (x', y') would have the equivalent
|
||||
relative motion (x' - x, y' - y). If a pointer motion caused the
|
||||
absolute pointer position to be clipped by for example the edge of the
|
||||
monitor, the relative motion is unaffected by the clipping and will
|
||||
represent the unclipped motion.
|
||||
|
||||
This event also contains non-accelerated motion deltas. The
|
||||
non-accelerated delta is, when applicable, the regular pointer motion
|
||||
delta as it was before having applied motion acceleration and other
|
||||
transformations such as normalization.
|
||||
|
||||
Note that the non-accelerated delta does not represent 'raw' events as
|
||||
they were read from some device. Pointer motion acceleration is device-
|
||||
and configuration-specific and non-accelerated deltas and accelerated
|
||||
deltas may have the same value on some devices.
|
||||
|
||||
Relative motions are not coupled to wl_pointer.motion events, and can be
|
||||
sent in combination with such events, but also independently. There may
|
||||
also be scenarios where wl_pointer.motion is sent, but there is no
|
||||
relative motion. The order of an absolute and relative motion event
|
||||
originating from the same physical motion is not guaranteed.
|
||||
|
||||
If the client needs button events or focus state, it can receive them
|
||||
from a wl_pointer object of the same seat that the wp_relative_pointer
|
||||
object is associated with.

<description summary="crop and scale interface to a wl_surface">
|
||||
An additional interface to a wl_surface object, which allows the
|
||||
client to specify the cropping and scaling of the surface
|
||||
contents.
|
||||
|
||||
This interface works with two concepts: the source rectangle (src_x,
|
||||
src_y, src_width, src_height), and the destination size (dst_width,
|
||||
dst_height). The contents of the source rectangle are scaled to the
|
||||
destination size, and content outside the source rectangle is ignored.
|
||||
This state is double-buffered, and is applied on the next
|
||||
wl_surface.commit.
|
||||
|
||||
The two parts of crop and scale state are independent: the source
|
||||
rectangle, and the destination size. Initially both are unset, that
|
||||
is, no scaling is applied. The whole of the current wl_buffer is
|
||||
used as the source, and the surface size is as defined in
|
||||
wl_surface.attach.
|
||||
|
||||
If the destination size is set, it causes the surface size to become
|
||||
dst_width, dst_height. The source (rectangle) is scaled to exactly
|
||||
this size. This overrides whatever the attached wl_buffer size is,
|
||||
unless the wl_buffer is NULL. If the wl_buffer is NULL, the surface
|
||||
has no content and therefore no size. Otherwise, the size is always
|
||||
at least 1x1 in surface local coordinates.
|
||||
|
||||
If the source rectangle is set, it defines what area of the wl_buffer is
|
||||
taken as the source. If the source rectangle is set and the destination
|
||||
size is not set, then src_width and src_height must be integers, and the
|
||||
surface size becomes the source rectangle size. This results in cropping
|
||||
without scaling. If src_width or src_height are not integers and
|
||||
destination size is not set, the bad_size protocol error is raised when
|
||||
the surface state is applied.
|
||||
|
||||
The coordinate transformations from buffer pixel coordinates up to
|
||||
the surface-local coordinates happen in the following order:
|
||||
1. buffer_transform (wl_surface.set_buffer_transform)
|
||||
2. buffer_scale (wl_surface.set_buffer_scale)
|
||||
3. crop and scale (wp_viewport.set*)
|
||||
This means, that the source rectangle coordinates of crop and scale
|
||||
are given in the coordinates after the buffer transform and scale,
|
||||
i.e. in the coordinates that would be the surface-local coordinates
|
||||
if the crop and scale was not applied.
|
||||
|
||||
If src_x or src_y are negative, the bad_value protocol error is raised.
|
||||
Otherwise, if the source rectangle is partially or completely outside of
|
||||
the non-NULL wl_buffer, then the out_of_buffer protocol error is raised
|
||||
when the surface state is applied. A NULL wl_buffer does not raise the
|
||||
out_of_buffer error.
|
||||
|
||||
If the wl_surface associated with the wp_viewport is destroyed,
|
||||
all wp_viewport requests except 'destroy' raise the protocol error
|
||||
no_surface.
|
||||
|
||||
If the wp_viewport object is destroyed, the crop and scale
|
||||
state is removed from the wl_surface. The change will be applied
|
||||
on the next wl_surface.commit.

<description summary="Protocol for requesting activation of surfaces">
|
||||
The way for a client to pass focus to another toplevel is as follows.
|
||||
|
||||
The client that intends to activate another toplevel uses the
|
||||
xdg_activation_v1.get_activation_token request to get an activation token.
|
||||
This token is then forwarded to the client, which is supposed to activate
|
||||
one of its surfaces, through a separate band of communication.
|
||||
|
||||
One established way of doing this is through the XDG_ACTIVATION_TOKEN
|
||||
environment variable of a newly launched child process. The child process
|
||||
should unset the environment variable again right after reading it out in
|
||||
order to avoid propagating it to other child processes.
|
||||
|
||||
Another established way exists for Applications implementing the D-Bus
|
||||
interface org.freedesktop.Application, which should get their token under
|
||||
activation-token on their platform_data.
|
||||
|
||||
In general activation tokens may be transferred across clients through
|
||||
means not described in this protocol.
|
||||
|
||||
The client to be activated will then pass the token
|
||||
it received to the xdg_activation_v1.activate request. The compositor can
|
||||
then use this token to decide how to react to the activation request.
|
||||
|
||||
The token the activating client gets may be ineffective either already at
|
||||
the time it receives it, for example if it was not focused, for focus
|
||||
stealing prevention. The activating client will have no way to discover
|
||||
the validity of the token, and may still forward it to the to be activated
|
||||
client.
|
||||
|
||||
The created activation token may optionally get information attached to it
|
||||
that can be used by the compositor to identify the application that we
|
||||
intend to activate. This can for example be used to display a visual hint
|
||||
about what application is being started.
|
||||
|
||||
Warning! The protocol described in this file is currently in the testing
|
||||
phase. Backward compatible changes may be added together with the
|
||||
corresponding interface version bump. Backward incompatible changes can
|
||||
only be done by creating a new major version of the extension.

<description summary="window decoration manager">
|
||||
This interface allows a compositor to announce support for server-side
|
||||
decorations.
|
||||
|
||||
A window decoration is a set of window controls as deemed appropriate by
|
||||
the party managing them, such as user interface components used to move,
|
||||
resize and change a window's state.
|
||||
|
||||
A client can use this protocol to request being decorated by a supporting
|
||||
compositor.
|
||||
|
||||
If compositor and client do not negotiate the use of a server-side
|
||||
decoration using this protocol, clients continue to self-decorate as they
|
||||
see fit.
|
||||
|
||||
Warning! The protocol described in this file is experimental and
|
||||
backward incompatible changes may be made. Backward compatible changes
|
||||
may be added together with the corresponding interface version bump.
|
||||
Backward incompatible changes are done by bumping the version number in
|
||||
the protocol and interface names and resetting the interface version.
|
||||
Once the protocol is to be declared stable, the 'z' prefix and the
|
||||
version number in the protocol and interface names are removed and the
|
||||
interface version number is reset.

Set the toplevel surface decoration mode. This informs the compositor

that the client prefers the provided decoration mode.
|

|

After requesting a decoration mode, the compositor will respond by
|
||||
emitting an xdg_surface.configure event. The client should then update
|
||||
its content, drawing it without decorations if the received mode is
|
||||
server-side decorations. The client must also acknowledge the configure
|
||||
when committing the new content (see xdg_surface.ack_configure).
|

The compositor can decide not to use the client's mode and enforce a
|

different mode instead.
|
||||
|

Clients whose decoration mode depend on the xdg_toplevel state may send
|
||||
a set_mode request in response to an xdg_surface.configure event and wait
|
||||
for the next xdg_surface.configure event to prevent unwanted state.
|
||||
Such clients are responsible for preventing configure loops and must
|
||||
make sure not to send multiple successive set_mode requests with the

same decoration mode.
