QMenuBar's CornerWidget hides on maximizing QMdiSubWindow

[vaibhav]

Hi,
I have QMainwindow with QMenubar to which I have added the QcomboBox as cornerwidget.

pMenuBar->setCornerWidget(pComboBox);

I have QMdiArea whose parent is QMainwindow and I have set this QMdiArea to its central widget.

mdi=new QMdiArea(this);
setCentralWidget( mdi );

Then I created QMdiSubWindow window.
QMdiSubWindow *midsubWindow= mdi->addSubWindow(Qwidget);

The application looks fine when the QMdiSubWindow is not Maximized (see Image.png)

But the moment I Maximize the QMdiSubWindow it Hides the Combobox that I have set on QMenubar as Corner widget(see maximize.png ).

I tried everything in my application but it looks like QT does not allow this.

Attached are the two images which shows the scenario.

Any help would be appreciated.

Thanks.
