Detailed Description
a physical tablet tool
An object that represents a physical tool that has been, or is currently in use with a
tablet in this seat. Each wp_tablet_tool object stays valid until the client destroys it;
the compositor reuses the wp_tablet_tool object to indicate that the object's respective
physical tool has come into proximity of a tablet again.
A wp_tablet_tool object's relation to a physical tool depends on the tablet's ability to
report serial numbers. If the tablet supports this capability, then the object represents
a specific physical tool and can be identified even when used on multiple tablets.
A tablet tool has a number of static characteristics, e.g. tool type, hardware_serial and
capabilities. These capabilities are sent in an event sequence after the
wp_tablet_seat.tool_added event before any actual events from this tool. This initial
event sequence is terminated by a wp_tablet_tool.done event.
Tablet tool events are grouped by wp_tablet_tool.frame events. Any events received before
a wp_tablet_tool.frame event should be considered part of the same hardware state change.

Member Function Documentation
void zwp_tablet_tool_v1_t::button (uint32_t serial, uint32_t button,
zwp_tablet_tool_v1_button_state const & state, bool post = true)
button event
Parameters
serial
button The button whose state has changed
state Whether the button was pressed or released
Sent whenever a button on the tool is pressed or released.
If a button is held down when the tool moves in or out of proximity, button events are
generated by the compositor. See wp_tablet_tool.proximity_in and
wp_tablet_tool.proximity_out for details.
Definition at line 6274 of file wayland-server-protocol-unstable.cpp.
void zwp_tablet_tool_v1_t::capability (zwp_tablet_tool_v1_capability const & capability, bool
post = true)
tool capability notification
Parameters
capability the capability
This event notifies the client of any capabilities of this tool, beyond the main set of
x/y axes and tip up/down detection.
One event is sent for each extra capability available on this tool.
This event is sent in the initial burst of events before the wp_tablet_tool.done event.
Definition at line 6204 of file wayland-server-protocol-unstable.cpp.
void zwp_tablet_tool_v1_t::distance (uint32_t distance, bool post = true)
distance change event
Parameters
distance The current distance value
Sent whenever the distance axis on a tool changes. The value of this event is normalized
to a value between 0 and 65535.
Note that distance may be nonzero even when a tool is not in logical contact. See the down
and up events for more details.
Definition at line 6249 of file wayland-server-protocol-unstable.cpp.
void zwp_tablet_tool_v1_t::done (bool post = true)
tool description events sequence complete This event signals the end of the initial burst
of descriptive events. A client may consider the static description of the tool to be
complete and finalize initialization of the tool.
Definition at line 6209 of file wayland-server-protocol-unstable.cpp.
void zwp_tablet_tool_v1_t::down (uint32_t serial, bool post = true)
tablet tool is making contact
Parameters
serial
Sent whenever the tablet tool comes in contact with the surface of the tablet.
If the tool is already in contact with the tablet when entering the input region, the
client owning said region will receive a wp_tablet.proximity_in event, followed by a
wp_tablet.down event and a wp_tablet.frame event.
Note that this event describes logical contact, not physical contact. On some devices, a
compositor may not consider a tool in logical contact until a minimum physical pressure
threshold is exceeded.
Definition at line 6229 of file wayland-server-protocol-unstable.cpp.
void zwp_tablet_tool_v1_t::frame (uint32_t time, bool post = true)
frame event
Parameters
time The time of the event with millisecond granularity
Marks the end of a series of axis and/or button updates from the tablet. The Wayland
protocol requires axis updates to be sent sequentially, however all events within a frame
should be considered one hardware event.
Definition at line 6279 of file wayland-server-protocol-unstable.cpp.
std::string wayland::server::resource_t::get_class () [inherited]
Retrieve the interface name (class) of a resource object.
Returns
Interface name of the resource object.
client_t wayland::server::resource_t::get_client () const [inherited]
Get the associated client
Returns
the client that owns the resource.
uint32_t wayland::server::resource_t::get_id () const [inherited]
Get the internal ID of the resource
Returns
the internal ID of the resource
unsigned int wayland::server::resource_t::get_version () const [inherited]
Get interface version
Returns
Interface version this resource has been constructed with.
void zwp_tablet_tool_v1_t::hardware_id_wacom (uint32_t hardware_id_hi, uint32_t
hardware_id_lo, bool post = true)
hardware id notification in Wacom's format
Parameters
hardware_id_hi the hardware id, most significant bits
hardware_id_lo the hardware id, least significant bits
This event notifies the client of a hardware id available on this tool.
The hardware id is a device-specific 64-bit id that provides extra information about the
tool in use, beyond the wl_tool.type enumeration. The format of the id is specific to
tablets made by Wacom Inc. For example, the hardware id of a Wacom Grip Pen (a stylus) is
0x802.
This event is sent in the initial burst of events before the wp_tablet_tool.done event.
Definition at line 6199 of file wayland-server-protocol-unstable.cpp.
void zwp_tablet_tool_v1_t::hardware_serial (uint32_t hardware_serial_hi, uint32_t
hardware_serial_lo, bool post = true)
unique hardware serial number of the tool
Parameters
hardware_serial_hi the unique serial number of the tool, most significant bits
hardware_serial_lo the unique serial number of the tool, least significant bits
If the physical tool can be identified by a unique 64-bit serial number, this event
notifies the client of this serial number.
If multiple tablets are available in the same seat and the tool is uniquely identifiable
by the serial number, that tool may move between tablets.
Otherwise, if the tool has no serial number and this event is missing, the tool is tied to
the tablet it first comes into proximity with. Even if the physical tool is used on
multiple tablets, separate wp_tablet_tool objects will be created, one per tablet.
This event is sent in the initial burst of events before the wp_tablet_tool.done event.
Definition at line 6194 of file wayland-server-protocol-unstable.cpp.
void zwp_tablet_tool_v1_t::motion (double x, double y, bool post = true)
motion event
Parameters
x surface-local x coordinate
y surface-local y coordinate
Sent whenever a tablet tool moves.
Definition at line 6239 of file wayland-server-protocol-unstable.cpp.
std::function< void()> & zwp_tablet_tool_v1_t::on_destroy ()
destroy the tool object This destroys the client's resource for this tool object.
Definition at line 6183 of file wayland-server-protocol-unstable.cpp.
std::function< void(uint32_t, surface_t, int32_t, int32_t)> &
zwp_tablet_tool_v1_t::on_set_cursor ()
set the tablet tool's surface
Parameters
serial serial of the enter event
surface
hotspot_x surface-local x coordinate
hotspot_y surface-local y coordinate
Sets the surface of the cursor used for this tool on the given tablet. This request only
takes effect if the tool is in proximity of one of the requesting client's surfaces or the
surface parameter is the current pointer surface. If there was a previous surface set with
this request it is replaced. If surface is NULL, the cursor image is hidden.
The parameters hotspot_x and hotspot_y define the position of the pointer surface relative
to the pointer location. Its top-left corner is always at (x, y) - (hotspot_x, hotspot_y),
where (x, y) are the coordinates of the pointer location, in surface-local coordinates.
On surface.attach requests to the pointer surface, hotspot_x and hotspot_y are decremented
by the x and y parameters passed to the request. Attach must be confirmed by
wl_surface.commit as usual.
The hotspot can also be updated by passing the currently set pointer surface to this
request with new values for hotspot_x and hotspot_y.
The current and pending input regions of the wl_surface are cleared, and
wl_surface.set_input_region is ignored until the wl_surface is no longer used as the
cursor. When the use as a cursor ends, the current and pending input regions become
undefined, and the wl_surface is unmapped.
This request gives the surface the role of a cursor. The role assigned by this request is
the same as assigned by wl_pointer.set_cursor meaning the same surface can be used both as
a wl_pointer cursor and a wp_tablet cursor. If the surface already has another role, it
raises a protocol error. The surface may be used on multiple tablets and across multiple
seats.
Definition at line 6177 of file wayland-server-protocol-unstable.cpp.
void wayland::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.
void zwp_tablet_tool_v1_t::post_role (std::string const & msg)
Post error: given wl_surface has another role.
Definition at line 6284 of file wayland-server-protocol-unstable.cpp.
void zwp_tablet_tool_v1_t::pressure (uint32_t pressure, bool post = true)
pressure change event
Parameters
pressure The current pressure value
Sent whenever the pressure axis on a tool changes. The value of this event is normalized
to a value between 0 and 65535.
Note that pressure may be nonzero even when a tool is not in logical contact. See the down
and up events for more details.
Definition at line 6244 of file wayland-server-protocol-unstable.cpp.
void zwp_tablet_tool_v1_t::proximity_in (uint32_t serial, zwp_tablet_v1_t const & tablet,
surface_t const & surface, bool post = true)
proximity in event
Parameters
serial
tablet The tablet the tool is in proximity of
surface The current surface the tablet tool is over
Notification that this tool is focused on a certain surface.
This event can be received when the tool has moved from one surface to another, or when
the tool has come back into proximity above the surface.
If any button is logically down when the tool comes into proximity, the respective button
event is sent after the proximity_in event but within the same frame as the proximity_in
event.
Definition at line 6219 of file wayland-server-protocol-unstable.cpp.
void zwp_tablet_tool_v1_t::proximity_out (bool post = true)
proximity out event Notification that this tool has either left proximity, or is no longer
focused on a certain surface.
When the tablet tool leaves proximity of the tablet, button release events are sent for
each button that was held down at the time of leaving proximity. These events are sent
before the proximity_out event but within the same wp_tablet.frame.
If the tool stays within proximity of the tablet, but the focus changes from one surface
to another, a button release event may not be sent until the button is actually released
or the tool leaves the proximity of the tablet.
Definition at line 6224 of file wayland-server-protocol-unstable.cpp.
bool wayland::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
void zwp_tablet_tool_v1_t::removed (bool post = true)
tool removed This event is sent when the tool is removed from the system and will send no
further events. Should the physical tool come back into proximity later, a new
wp_tablet_tool object will be created.
It is compositor-dependent when a tool is removed. A compositor may remove a tool on
proximity out, tablet removal or any other reason. A compositor may also keep a tool alive
until shutdown.
If the tool is currently in proximity, a proximity_out event will be sent before the
removed event. See wp_tablet_tool.proximity_out for the handling of any buttons logically
down.
When this event is received, the client must wp_tablet_tool.destroy the object.
Definition at line 6214 of file wayland-server-protocol-unstable.cpp.
void zwp_tablet_tool_v1_t::rotation (int32_t degrees, bool post = true)
z-rotation change event
Parameters
degrees The current rotation of the Z axis
Sent whenever the z-rotation axis on the tool changes. The rotation value is in 0.01 of a
degree clockwise from the tool's logical neutral position.
Definition at line 6259 of file wayland-server-protocol-unstable.cpp.
void zwp_tablet_tool_v1_t::slider (int32_t position, bool post = true)
Slider position change event.
Parameters
position The current position of slider
Sent whenever the slider position on the tool changes. The value is normalized between
-65535 and 65535, with 0 as the logical neutral position of the slider.
The slider is available on e.g. the Wacom Airbrush tool.
Definition at line 6264 of file wayland-server-protocol-unstable.cpp.
void zwp_tablet_tool_v1_t::tilt (int32_t tilt_x, int32_t tilt_y, bool post = true)
tilt change event
Parameters
tilt_x The current value of the X tilt axis
tilt_y The current value of the Y tilt axis
Sent whenever one or both of the tilt axes on a tool change. Each tilt value is in 0.01 of
a degree, relative to the z-axis of the tablet. The angle is positive when the top of a
tool tilts along the positive x or y axis.
Definition at line 6254 of file wayland-server-protocol-unstable.cpp.
void zwp_tablet_tool_v1_t::type (zwp_tablet_tool_v1_type const & tool_type, bool post = true)
tool type
Parameters
tool_type the physical tool type
The tool type is the high-level type of the tool and usually decides the interaction
expected from this tool.
This event is sent in the initial burst of events before the wp_tablet_tool.done event.
Definition at line 6189 of file wayland-server-protocol-unstable.cpp.
void zwp_tablet_tool_v1_t::up (bool post = true)
tablet tool is no longer making contact Sent whenever the tablet tool stops making contact
with the surface of the tablet, or when the tablet tool moves out of the input region and
the compositor grab (if any) is dismissed.
If the tablet tool moves out of the input region while in contact with the surface of the
tablet and the compositor does not have an ongoing grab on the surface, the client owning
said region will receive a wp_tablet.up event, followed by a wp_tablet.proximity_out event
and a wp_tablet.frame event. If the compositor has an ongoing grab on this device, this
event sequence is sent whenever the grab is dismissed in the future.
Note that this event describes logical contact, not physical contact. On some devices, a
compositor may not consider a tool out of logical contact until physical pressure falls
below a specific threshold.
Definition at line 6234 of file wayland-server-protocol-unstable.cpp.
void zwp_tablet_tool_v1_t::wheel (int32_t degrees, int32_t clicks, bool post = true)
Wheel delta event.
Parameters
degrees The wheel delta in 0.01 of a degree
clicks The wheel delta in discrete clicks
Sent whenever the wheel on the tool emits an event. This event contains two values for the
same axis change. The degrees value is in 0.01 of a degree in the same orientation as the
wl_pointer.vertical_scroll axis. The clicks value is in discrete logical clicks of the
mouse wheel. This value may be zero if the movement of the wheel was less than one logical
click.
Clients should choose either value and avoid mixing degrees and clicks. The compositor may
accumulate values smaller than a logical click and emulate click events when a certain
threshold is met. Thus, wl_tablet_tool.wheel events with non-zero clicks values may have
different degrees values.
