* Extend touch events.Laszlo Agocs2011-12-092-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The capability flags indicate which information is valid in the touch points. Previously there was no way to tell if e.g. the value returned by pressure() is actually the value provided by the driver/device or it is just something bogus due to pressure not being supported. The points' flags return information about the individual touch points. One use case is to differentiate between touches made by finger and pen. Velocity, if available, is now also exposed. Each touch point can now contain an additional list of "raw" positions. These points are not reported individually but are taken into account in some way by the underlying device and drivers to generate the final, "accurate" touch point. In case the underlying drivers expose these additional positions, they are made available in the lists returned by the touch points' rawScreenPosition(). The raw positions are only available in screen coordinates to prevent wasting time with mapping from global positions in applications that do not use this data. Instead, apps can query the QWindow to which the touch event was sent via QTouchEvent::window() and can call mapFromGlobal() manually if they need local raw positions. The capability and device type information is now held in a new QTouchDevice class. Each touch event will contain only a pointer to one of the global QTouchDevice instances. On top of type and capability, the new class also contains a name which can be used to differentiate between multiple touch input devices (i.e. to tell from which one a given QTouchEvent originates from). The introduction of QTouchDevice has three implications: The QTouchEvent constructor and QWindowSystemInterface::handleTouchEvent need to be changed (to pass a QTouchDevice pointer instead of merely a device type value), and each platform or generic plug-in is now responsible for registering one or more devices using the new API QWindowSystemInterface::registerTouchDevice.

* Remove mtdev dependency from the touchscreen QPA plugin.Laszlo Agocs2011-10-216-142/+145
| | | | | | | | | | There is no reason to enforce the usage of the mtdev library. As long as ABS_MT_TRACKING_ID is provided protocol type A is perfectly enough. This makes the plugin more suitable for embedded systems. Change-Id: I73ce4a1056a6dc27daacb69dc4761bca393a7e43 Reviewed-by: Paul Olav Tvete <paul.tvete@nokia.com>
* Calculate an area in the touchscreen qpa plugin.Laszlo Agocs2011-10-132-3/+6
| | | | | | | | | | | | Instead of ignoring the touch major/minor and returning a rectangle with width and height of 1, the size of the area is now calculated based on the major. This is incomplete and far from perfect but at least it makes visualizers, like the fingerpaint example app, work out of the box.

* Migrate the touchscreen generic qpa plugin to QWindow.Laszlo Agocs2011-10-131-4/+5
| | | | | | | | | This plugin was still using QApplication and QDesktopWidget. The code is now migrated to QGuiApplication, QWindow, and QScreen.

* Implement todos in touchscreen generic plug-in.Laszlo Agocs2011-07-196-28/+62
| | | | | | | | | | | | The patch implements periodic clearing of the point states when no activity occurs (i.e. no ev_syn is coming at all, meaning that most probably all the fingers are already up) and also moves the entire functionality into a separate thread even when used as a plug-in.
