Summary [Qt] Add support for touch events in QWebView and QGraphicsWebView

QWebPage has been extended with support for handling QTouchEvents and forwarding them to the event handler. However what is still missing is 1) Forwarding touch events from QGraphicsWebView and QWebView to QWebPage 2) Enabling the WA_AcceptsTouch widget attribute It may seem like we would have to dynamically toggle the WA_AcceptsTouchEvents widget attribute, but since in the long run we want to have have QWebPage also interpret touch events (for example for panning), we might as well enable it all the time ;-)

Comment on attachment 44866 [details] Patch for adding support for touch events in QWebView and QGraphicsWebView. The patch looks good to me! Just a few minor style nitpicks that need to be fixed before we can land this: > + > +#if QT_VERSION >= QT_VERSION_CHECK(4, 6, 0) > + if (d->page) { > + if (event->type() == QEvent::TouchBegin > + || event->type() == QEvent::TouchEnd > + || event->type() == QEvent::TouchUpdate) { > + d->page->event(event); > + } The curly braces are left out when the body is only a one-liner. I would recommend combining the two if statements: if (d->page && event->type() == ... && ... ) d->page->event(event); Also, with the above code we always call QWidget::event() with the touch event, which will convert the first touch to a mouse event (according to the docs). I think perhaps the code should be like: if (...) { d->page->event(event); if (event->isAccepted()) return true; } ... else we call QWidget::event. The same for QGraphicsWebView and QWebView of course.
