C++ (Cpp) QSGView Examples

Example #1

File: QtTouchViewInterface.cpp Project: sysrqb/chromium-src

QJSEngine* QtTouchViewInterface::engine()
{
    QSGView* view = qobject_cast<QSGView*>(m_pageView->canvas());
    if (view)
        return view->engine();
    return 0;
}

Example #2

File: main.cpp Project: yinyunqiao/qtdeclarative

int main(int argc, char ** argv)

//![0]
    QStringList dataList;
    dataList.append("Item 1");
