使用QPainter绘制html页面

Question

如何绘制html页面？

QWebView *view = new QWebView();
view.Load(Url("http://www.google.com"));

QPrinter printer = new Qprinter();

如何绘制此视图？

Answer 1

如果只是想打印页面，只需使用QWebView::print(QPrinter *)方法即可。

如果要将视图绘制到任意绘制设备，请使用QWebView::render(QPaintDevice *)。此方法在任何QWidget子类上都可用。

Answer 2

MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow)
{          QWebView view = new QWebView(this);
           //Set settings
           view->settings()->setAttribute(QWebSettings::JavaEnabled, true);
           view->settings()->setAttribute(QWebSettings::JavascriptEnabled, true);
           view->settings()->setAttribute(QWebSettings::JavascriptCanOpenWindows, false);
           view->settings()->setAttribute(QWebSettings::JavascriptCanAccessClipboard, false);
           view->settings()->setAttribute(QWebSettings::AutoLoadImages, true);
           //Load URl
           view->page()->mainFrame()->load(QUrl("http://www.habrahabr.ru"));
           //Connect signal loadFinished
           connect(view, SIGNAL(loadFinished(bool)), SLOT(finishLoading(bool)))
}

void MainWindow::finishLoading(bool)
 {
    //Printing
    QPrinter *printer = new QPrinter(QPrinter::HighResolution);
    printer->setPrinterName("Microsoft XPS Document Writer");
    printer->setOutputFileName("out.xps");
    view->page()->mainFrame()->print(printer);
 }

几乎所有的东西都能工作，除了小部件。不告诉我怎么配置？FontFamily、FontSize、页脚和页眉、链接...
