* Introduce QInputDevice hierarchy; replace QTouchDeviceShawn Rutledge2020-06-161-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Add support for filtering in the qevdevtouch pluginGunnar Sletta2016-12-131-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a Kalman filter to the evdev touch plugin which samples velocity and position in x and y direction and uses this to emit touch points in sync with the application's repaint rate. The filter also allows for basic prediction based on current position and velocity estimates. Filtering is opt-in, and can be enabled by passing for instance > app -plugin evdevtouch:/dev/touchscreen:filtered:prediction=16 The logic relies on a stable QWindow::requestUpdate() and will work best in combination with QtQuick and blocking swap buffers (or equivalent). QScreen::refreshRate() will also have to be reasonably accurate. [ChangeLog][Platform Specific Changes] The evdevtouch plugin now has the option to apply filtering and prediction. Enabled by passing "filtered" as an argument. Prediction can be specified by passing "prediction=X" as an argument, where X is in milliseconds.

* Rework privateFeatureLars Knoll2016-08-191-2/+2
| | | | | | | | | | | | | | | | | | privateFeature would add QT_NO_FEATURE to the DEFINES in the private .pri file, which was somewhat inelegant. Additionally, it would add the feature to the _public_ QT_CONFIG variable, which was plain wrong. Replace the implementation with the one just introduced for publicFeature, with the difference that the features are written to the private files instead. As this entirely disposes of the old system, all usages in the project files need to be replaced atomically as well.

* Add a way for auxiliary threads to handle events without CoreAppThiago Macieira2015-07-181-1/+2
| | | | | | | | | | | | | | Long-lived threads started by Qt itself can now receive events even if QCoreApplication hasn't been created. This is required in all threads we start that will handle events, unless we're sure that the thread will exit before the global application object begins destruction. Otherwise, those threads will have race conditions dealing with the event delivery system trying to call the QCoreApplication::notify() virtual while the object is being destroyed.

Follow the exact same structure as evdevmouse and keyboard. We must do monitoring via device discovery just like we do for keyboards and mice. Otherwise the usage of touchscreens that connect via USB or can be turned on/off independently from the board becomes troublesome.
