348 //! Wayland protocol for graphics tablets
349 //!
350 //! This description provides a high-level overview of the interplay between
351 //! the interfaces defined this protocol. For details, see the protocol
352 //! specification.
353 //!
354 //! More than one tablet may exist, and device-specifics matter. Tablets are
355 //! not represented by a single virtual device like wl_pointer. A client
356 //! binds to the tablet manager object which is just a proxy object. From
357 //! that, the client requests wp_tablet_manager.get_tablet_seat(wl_seat)
358 //! and that returns the actual interface that has all the tablets. With
359 //! this indirection, we can avoid merging wp_tablet into the actual Wayland
360 //! protocol, a long-term benefit.
361 //!
362 //! The wp_tablet_seat sends a "tablet added" event for each tablet
363 //! connected. That event is followed by descriptive events about the
364 //! hardware; currently that includes events for name, vid/pid and
365 //! a wp_tablet.path event that describes a local path. This path can be
366 //! used to uniquely identify a tablet or get more information through
367 //! libwacom. Emulated or nested tablets can skip any of those, e.g. a
368 //! virtual tablet may not have a vid/pid. The sequence of descriptive
369 //! events is terminated by a wp_tablet.done event to signal that a client
370 //! may now finalize any initialization for that tablet.
371 //!
372 //! Events from tablets require a tool in proximity. Tools are also managed
373 //! by the tablet seat; a "tool added" event is sent whenever a tool is new
374 //! to the compositor. That event is followed by a number of descriptive
375 //! events about the hardware; currently that includes capabilities,
376 //! hardware id and serial number, and tool type. Similar to the tablet
377 //! interface, a wp_tablet_tool.done event is sent to terminate that initial
378 //! sequence.
379 //!
380 //! Any event from a tool happens on the wp_tablet_tool interface. When the
381 //! tool gets into proximity of the tablet, a proximity_in event is sent on
382 //! the wp_tablet_tool interface, listing the tablet and the surface. That
383 //! event is followed by a motion event with the coordinates. After that,
384 //! it's the usual motion, axis, button, etc. events. The protocol's
385 //! serialisation means events are grouped by wp_tablet_tool.frame events.
386 //!
387 //! Two special events (that don't exist in X) are down and up. They signal
388 //! "tip touching the surface". For tablets without real proximity
389 //! detection, the sequence is: proximity_in, motion, down, frame.
390 //!
391 //! When the tool leaves proximity, a proximity_out event is sent. If any
392 //! button is still down, a button release event is sent before this
393 //! proximity event. These button events are sent in the same frame as the
394 //! proximity event to signal to the client that the buttons were held when
395 //! the tool left proximity.
396 //!
397 //! If the tool moves out of the surface but stays in proximity (i.e.
398 //! between windows), compositor-specific grab policies apply. This usually
399 //! means that the proximity-out is delayed until all buttons are released.
400 //!
401 //! Moving a tool physically from one tablet to the other has no real effect
402 //! on the protocol, since we already have the tool object from the "tool
403 //! added" event. All the information is already there and the proximity
404 //! events on both tablets are all a client needs to reconstruct what
405 //! happened.
406 //!
407 //! Some extra axes are normalized, i.e. the client knows the range as
408 //! specified in the protocol (e.g. [0, 65535]), the granularity however is
409 //! unknown. The current normalized axes are pressure, distance, and slider.
410 //!
411 //! Other extra axes are in physical units as specified in the protocol.
412 //! The current extra axes with physical units are tilt, rotation and
413 //! wheel rotation.
414 //!
415 //! Since tablets work independently of the pointer controlled by the mouse,
416 //! the focus handling is independent too and controlled by proximity.
417 //! The wp_tablet_tool.set_cursor request sets a tool-specific cursor.
418 //! This cursor surface may be the same as the mouse cursor, and it may be
419 //! the same across tools but it is possible to be more fine-grained. For
420 //! example, a client may set different cursors for the pen and eraser.
421 //!
422 //! Tools are generally independent of tablets and it is
423 //! compositor-specific policy when a tool can be removed. Common approaches
424 //! will likely include some form of removing a tool when all tablets the
425 //! tool was used on are removed.
