Question

我目前正在尝试开发一个基本的浏览器网站，以便使用qt框架在特定的互联网网站上冲浪。我创建了一个继承QWebView并重新实现createWindow函数的MyWindow类，以便在新的浏览器窗口中处理潜在弹出窗口的打开。它在“正常”导航期间运行良好，但是当我遇到如下链接时：

<a class="lien_default" href="javascript:popupChat2('foo.php?id=42250')">bar</a>

如果链接页面有Flash内容，则会创建一个新窗口，但它是空的。这是popupChat2的代码：

function popupChat2(page)
{fenetre=window.open(page,'chat','top=0, left=0, width=800, height=500, resizable=no, toolbar=no, scrollbars=no, status=no, menubar=no, titlebar=no, dependent=yes');}

我还尝试保存本地链接页面，如果我用一个非常简单的qt浏览器网页打开它，就像这样：

的main.cpp

#include "mainwindow.h"
#include <QApplication>

int main(int argc, char *argv[])
{
   QApplication a(argc, argv);
   MainWindow w;
   w.show();

   return a.exec();
}

mainwindow.cpp

#include "mainwindow.h"
#include "ui_mainwindow.h"

MainWindow::MainWindow(QWidget *parent) :
   QMainWindow(parent),
   ui(new Ui::MainWindow)
{
   QUrl url("file:///[url of the page locally saved with flash player content]");
   ui->setupUi(this);
   QWebSettings *settings = ui->webView->settings();
   settings->setAttribute(QWebSettings::JavascriptEnabled, true);
   settings->setAttribute(QWebSettings::PluginsEnabled, true);
   settings->setAttribute(QWebSettings::AutoLoadImages, true);
   settings->setAttribute(QWebSettings::JavaEnabled, false);
   settings->setAttribute(QWebSettings::JavascriptCanOpenWindows, true);
   settings->setAttribute(QWebSettings::LocalContentCanAccessFileUrls,true);

   ui->webView->load(url);
   ui->webView->show();
}

MainWindow::~MainWindow()
{
   delete ui;
}

正确加载。以下是我的createWindow函数的代码和带有flash内容的链接页面的代码：

MyWindow *MyWindow::createWindow(QWebPage::WebWindowType type)
      {
        Q_UNUSED(type);
        MyWindow *webView = new MyWindow;

        webView->settings()->setAttribute(QWebSettings::PluginsEnabled, true);
        webView->settings()->setAttribute(QWebSettings::JavascriptEnabled, true);
        webView->settings()->setAttribute(QWebSettings::JavascriptCanOpenWindows, true);
        webView->settings()->setAttribute(QWebSettings::DeveloperExtrasEnabled, true);

        webView->setAttribute(Qt::WA_DeleteOnClose, true);

        QWebPage *newWeb = new QWebPage(webView);
        newWeb->setNetworkAccessManager(page()->networkAccessManager());

        webView->setPage(newWeb);
        webView->show();

        return webView;
    }

Answer 1

您在webView上应用QWebSettings，但它们实际存储在webView->page()中。

所以当你执行webView->setPage(newWeb);时，你会恢复默认的QWebSettings，包括所需的QWebSettings :: PluginsEnabled。

事实上，您似乎不需要额外的QWebPage，只需将您的QNAM设置为默认值：

webView->page()->setNetworkAccessManager(page()->networkAccessManager());

createWindow函数不加载flashplayer内容
