| 211 | //! By contrast, with explicit synchronization, DRM synchronization object |

| 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. |
