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

VladimirSk

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/"));
}

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.
