The duplicated hash tables in QGuiApplicationPrivate and QApplicationPrivate are now unified into one single hash table in QGuiApplicationPrivate. This also reduced the number of lookups. The extra processing needed to keep the touch points' first/lastPos values in sync is now done only once, in QGuiApplication. This eliminates the performance penalty (for widget-based apps) that was introduced during the QPA migration. As an added bonus the patch adds support for touch events arriving simultaenously from multiple devices. This was broken before: As there is no guarantee that two devices/drivers will not send touch points with the same ID, using structures with only the ID as key is wrong. The proper key is composed of the device ID (that is, a QTouchDevice pointer) and the touch point ID. The exported internal function qt_translateRawTouchEvent() has been removed. This function cannot work properly in the QPA world: It injected touches into the widget subsystem (QApplication) only which is wrong, and would result in half-filled touch events due to not routing the injected data through QGuiApplication. Autotests using this function are migrated to QWindowSystemInterface::handleTouchEvent(). Change-Id: I7632781d77f9e0ac4626fd7c9933511c94492156 Reviewed-by: Samuel Rødal <samuel.rodal@nokia.com> |
