[Qt-interest] QMdiSubWindow WA_DeleteOnClose problem

[Vidit...]

Hello



I have just started learning QT and I’m doing pretty well. But I’m stuck on
this problem for weeks now. If someone could help me, I appreciate.



I create a QMdiSubwindow and set its attribute to DeleteOnClose.

The signal destroyed(QObject*) is connected to a custom slot.



The problem is when I call delete QMdiSubWindow explicitly (in the code),
the slot is called, but if I close the window using GUI, the subwindow gets
deleted but the slot is never called.



Here is the simplified code:





class TraceWindowArea : public QMdiArea

{

    Q_OBJECT

public:

    TraceWindowArea(QWidget *parent);



public slots:

    void openNewWindow(const HostStruct *);



private slots:

    void TraceWindowClosing(QObject*);



    //some other stuff too...

};



void TraceWindowArea::openNewWindow()

{

        Window = new QMdiSubWindow(this);



        Window->setAttribute(Qt::WA_DeleteOnClose);



        QTextEdit *TextBrowser = new QTextEdit(Window);

        Window->setWidget(TextBrowser);



        Window->show();



        connect(Window, SIGNAL(destroyed(QObject*)), this,
SLOT(TraceWindowClosing(QObject*)));

}



void TraceWindowArea::TraceWindowClosing(QObject* ClosingWindow)

{

    //just for testing purpose

    QWidget * a = new QWidget(0);

    a->show();

}





Thanks
