WebKit (Qt 5.3) not works on Windows XP SP3.



  • WebKit (Qt 5.3) not works on Windows XP SP3.

    Hello!

    A very simple 32-bit application has been written.
    This application uses QtWebView to display WEB page in main window.
    The application has been developed on Windows, Qt 5.3.1 for Windows 32-bit (VS 2013).
    The application has been builded in Visual Studio 2013 (Update 3) with toolset v120_xp.
    The application works correctly on Windows 7 (32-bit and 64-bit).

    But this application not works on Windows XP SP3 32-bit - terminates during displaying WEB page on QWebView.
    If I comment the line 'ui.webView->setUrl(QUrl(...))' in the source code (see below) - this application starts without problems.

    How to fix this problem?

    Thanks!

    Source code:

    // main.cpp

    @
    #include "qtwebkit.h"
    #include <QtWidgets/QApplication>

    int main(int argc, char *argv[])
    {
    QApplication a(argc, argv);
    a.addLibraryPath(QCoreApplication::applicationDirPath() + "/plugins");
    QtWebKit w;
    w.show();
    return a.exec();
    }
    @

    // qtwebkit.h

    @
    #ifndef QTWEBKIT_H
    #define QTWEBKIT_H

    #include <QtWidgets/QMainWindow>
    #include "ui_qtwebkit.h"

    class QtWebKit : public QMainWindow
    {
    Q_OBJECT
    public:
    QtWebKit(QWidget parent = 0);
    ~QtWebKit();
    protected:
    void showEvent(QShowEvent
    event);
    private:
    Ui::QtWebKitClass ui;
    };

    #endif // QTWEBKIT_H
    @

    // qtwebkit.cpp

    @
    #include "qtwebkit.h"

    #include <QObject>
    #include <QWebView>

    QtWebKit::QtWebKit(QWidget *parent)
    : QMainWindow(parent)
    {
    ui.setupUi(this);
    }

    QtWebKit::~QtWebKit()
    {
    }

    void QtWebKit::showEvent(QShowEvent* event)
    {
    ui.webView->setVisible(true);
    ui.webView->setUrl(QUrl("http://www.ibm.com/us/en/"));
    }

  • Please check the information available on "Supported Platforms":http://qt.digia.com/product/Qt-Framework/Supported-Platforms/

    Windows XP 32bit is supported by Qt 4.8 and only for
    VS 2008
    VS 2010
    MinGW 4.4



  • I have no problem running your example on WinXP with my Qt-5.3.1 compiled with VS2013.

    What your configure cmd looks like?
    Are you sure that all components were compiled for WinXP ?



  • Big thanks to all!

    I found the problem.
    Qt WebKit not working only when I used OpenSSL (v1.0.1e), which has been compiled with Visual Studio v120_xp toolset. All other applications and modules are working successfully with this library.
    Qt WebKit works successfully if I use, for example, the "old" version of OpenSSL (v1.0.1e), which has been compiled with v100 toolset.
