* Refactor pointer event hierarchyShawn Rutledge2020-07-101-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some goals that have hopefully been achieved are: - make QPointerEvent and QEventPoint resemble their Qt Quick counterparts to such an extent that we can remove those wrappers and go back to delivering the original events in Qt Quick - make QEventPoint much smaller than QTouchEvent::TouchPoint, with no pimpl - remove most public setters - reduce the usage of complex constructors that take many arguments - don't repeat ourselves: move accessors and storage upwards rather than having redundant ones in subclasses - standardize the set of accessors in QPointerEvent - maintain source compatibility as much as possible: do not require modifying event-handling code in any QWidget subclass To avoid public setters we now introduce a few QMutable* subclasses. This is a bit like the Builder pattern except that it doesn't involve constructing a separate disposable object: the main event type can be cast to the mutable type at any time to enable modifications, iff the code is linked with gui-private. Therefore event classes can have less-"complete" constructors, because internal Qt code can use setters the same way it could use the ones in QTouchEvent before; and the event classes don't need many friends. Even some read-accessors can be kept private unless we are sure we want to expose them.

* Introduce QInputDevice hierarchy; replace QTouchDeviceShawn Rutledge2020-06-161-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have seen during the Qt 5 series that QMouseEvent::source() does not provide enough information: if it is synthesized, it could have come from any device for which mouse events are synthesized, not only from a touchscreen. By providing in every QInputEvent as complete information about the actual source device as possible, we will enable very fine-tuned behavior in the object that handles each event. Further, we would like to support multiple keyboards, pointing devices, and named groups of devices that are known as "seats" in Wayland. In Qt 5, QPA plugins registered each touchscreen as it was discovered. Now we extend this pattern to all input devices. This new requirement can be implemented gradually; for now, if a QTWSI input event is received wtihout a device pointer, a default "core" device will be created on-the-fly, and a warning emitted. In Qt 5, QTouchEvent::TouchPoint::id() was forced to be unique even when multiple devices were in use simultaneously. Now that each event identifies the device it came from, this hack is no longer needed. A stub of the new QPointerEvent is added; it will be developed further in subsequent patches. [ChangeLog][QtGui][QInputEvent] Every QInputEvent now carries a pointer to an instance of QInputDevice, or the subclass QPointingDevice in case of mouse, touch and tablet events. Each platform plugin is expected to create the device instances, register them, and provide valid pointers with all input events. If this is not done, warnings are emitted and default devices are created as necessary. When the device has accurate information, it provides the opportunity to fine-tune behavior depending on device type and capabilities: for example if a QMouseEvent is synthesized from a touchscreen, the recipient can see which touchscreen it came from. Each device also has a seatName to distinguish users on multi-user windowing systems. Touchpoint IDs are no longer unique on their own, but the combination of ID and device is.

* wasm: store and pass canvases as emscripten::valMorten Johan Sørvig2020-02-121-3/+1
| | | | | | | | | | | | | | | | | | | | Store and pass canvases as emscripten::val instead of a QString containing the element id. This simplifies code which interacts with the canvas using the emscripten::val API, by removing the need to look up with getElementById. The Emscripten C event API does not accept emscripten::val, and using the element id is still needed here. emscripten::val does not provide a hash key suitable for use with QHash, but does provide an equality-compare in the form of val::equals(). Change the canvas->screen mapping code to use a QVector instead of a QHash. Change-Id: I1dbdbbc8fb06bb869031f1500e83ae2d64780a7f Reviewed-by: Lorn Potter <lorn.potter@gmail.com>
* wasm: Specify event targets by CSS selectors; Support emsdk >= 1.39.5Morten Johan Sørvig2020-02-051-13/+12
| | | | | | | | | | | | | | | | DISABLE_DEPRECATED_FIND_EVENT_TARGET_BEHAVIOR is now on by default, which means that functions like emscripten_set_keydown_callback() now expects CSS selectors (e.g. "#canvas_id" instead of "canvas_id"). In addition, Module.canvas is no more. Add a deprecation warning in case someone is setting it and expects Qt to use it. (qtloader.js sets qtCanvasElements instead). This bumps the minimum supported emsdk version to 1.39.5. Fixes: QTBUG-74601 Change-Id: I8c46ce170143f969e6281824f78b1bb809c267ab Reviewed-by: Lorn Potter <lorn.potter@gmail.com>

(This worked before since there was only one screen, and no need to connect each screen instance to specific canvas.)
