* evdev: Prevent race condition in touch events processingJungi Byun2022-01-261-1/+38
| | | | | | | | | | | | | | | | | Unlike other input devices, touch devices are managed by corresponding handler threads which are not the main thread. InputEvent that is inherited by TouchEvent has a constant pointer member for device, but in touch events case, handler threads may destroy the device which is pointed by events while processing these events in main thread, and this may cause critical potential issues such as crash. In order to prevent this race condition, move device of QEvdevTouchScreenHandler into main thread and delete this device later if QGuiApplication instance exists when handler thread quits, and check event's device is valid when processing touch events.

* webOS: Support mapping evdev keyboard and touchscreen to specific windowElvis Lee2020-10-271-5/+5
| | | | | | | | | | | | | | | | | | | | | | First we refactor QTouchOutputMapping into a QOutputMapping base class and a QDefaultOutputMapping subclass, because it will be used to map more kinds of devices, not only touchscreens. On WebOS, the plan is to have a custom subclass that overrides an additional windowForDeviceNode() virtual function, so that events from specific devices can be sent to specific windows. But in the future, Qt may have a more generic mechanism for mapping devices to screens, and of course windows are displayed on screens; so this direct device->window mapping is likely to be temporary. In the QT_QPA_EGLFS_KMS_CONFIG JSON configuration, symlinked device nodes are now supported.

* Refactor pointer event hierarchyShawn Rutledge2020-07-101-28/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Rutledge2020-06-163-30/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Fix it to check for d's validity first. This can occur when a device is connected then disconnected right after, so that it's gone by the time we get the notification from udev.

* Add support for filtering in the qevdevtouch pluginGunnar Sletta2016-12-133-37/+412
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* eglfs: Add missing virtual layout setting for DRM/KMSLaszlo Agocs2016-09-221-11/+19
| | | | | | | | | | | | | Just setting virtualDesktopLayout and virtualIndex are not always enough. To create more complex shapes (e.g. a T-shaped cluster) the top-left position has to be specified explicitly. Enable this via an optional virtualPos property. This also involves improving evdevtouch's mapping functionality. Instead of fragile indices, rely on the screen name instead.
