ui->webview->setCursor(Qt::WhatsThisCursor); Does not seem to do anything. QApplication::setOverrideCursor(Qt::WhatsThisCursor); does work also on webview. I'm not sure what version of webkit is inside QtSDK/Desktop/Qt/473/gcc/lib/libQtWebKit.so.4.7.3 but that's what I'm using.
The Qt port has been removed from WebKit, resolving.
