QtWebkit resolving event dispatcher
i'm playing around with QtWebkit lately and i was wondering if it is possible to resolve the element displayed in the QWebView which is responsible for an event, e.g. a MouseEvent.
I've installed an EventFilter function at the WebView Object with a function like this:
bool WebKitManager::eventFilter(QObject *obj, QEvent *event)
{
if(event->type() == QEvent::MouseButtonRelease)
{
QMouseEvent *mouseEvent = static_cast<QMouseEvent *>(event);
if(mouseEvent->button() == Qt::LeftButton)
{

}
}
return false;
}
Is there any way to get a reference to the clicked element that is displayed in the QWebView? As far as i can tell, the passed QObject equals the WebView object and the event doesn't seem to hold reference to its dispatcher.
Since i'm far away from beeing a c++ professional i sincerely hope i missed something and you guys can help me out :)
Thanks in advance Timo
I believe what you could do is:
- cast object parameter to QWebView
- get QWebFrame under mouse via vebView->page()->frameAt() method
- use hitTestContent method of the returned frame to detect the element for the given mouse position
Below is an example:
bool WebKitManager::eventFilter(QObject *object, QEvent *event)
{
if (event->type() == QEvent::MouseButtonRelease)
{
QMouseEvent *mouseEvent = static_cast<QMouseEvent *>(event);
if (mouseEvent->button() == Qt::LeftButton)
{
QWebView *view = dynamic_cast<QWebView*>(object);
QPoint pos = view->mapFromGlobal(mouseEvent->globalPos());
qDebug() << view->url().toString() << " clicked at x:" << pos.x() << " y:" << pos.y();
QWebFrame *frame = view->page()->frameAt(mouseEvent->pos());
if (frame!=NULL)
{
QWebHitTestResult hitTestResult = frame->hitTestContent(pos);
qDebug() << "element" << hitTestResult.element().localName();
}
}
}
return false;
}
hope this helps, regards
Use qobject_cast
instead of dynamic_cast
.
