Is this a bug?

[gmat4321]

On application startup I create a QMenu then after I create a QWidget alll within the constructor. By createing a QWidget the menu becomes disabled. If the QWidget is created after calling show() everything is fine.
I'm using the commercial version of 4.4.1 installed as is, not rebuilt, and building the project in Visual Studio 2008. I checked my Mac version and it works correctly, but I have done a local rebuild on the Mac.

The code ....

#ifndef QTAPPLICATION_H
#define QTAPPLICATION_H
 
#include <QtGui/QApplication>
#include <QtGui/QMainWindow>
#include <QtGui/QWidget>
#include <QtGui/QAction>
#include <QtGui/QMenu>
#include <QtGui/QMenuBar>
 
class QTApplication : public QMainWindow
{
	Q_OBJECT
 
public:
	QTApplication(QWidget *parent = 0, Qt::WFlags flags = 0);
	virtual ~QTApplication();
};
 
#endif // QTAPPLICATION_H

#ifndef QTAPPLICATION_H
#define QTAPPLICATION_H

#include <QtGui/QApplication>
#include <QtGui/QMainWindow>
#include <QtGui/QWidget>
#include <QtGui/QAction>
#include <QtGui/QMenu>
#include <QtGui/QMenuBar>

class QTApplication : public QMainWindow
{
	Q_OBJECT

public:
	QTApplication(QWidget *parent = 0, Qt::WFlags flags = 0);
	virtual ~QTApplication();
};

#endif // QTAPPLICATION_H

	menu->addAction( new QAction(tr("exit"), this) );
