Deleteing QWinWidget

[elizabeth.h1]

Hello
I am using mfc to Qt migration and I am showing Qt dialogs in my Mfc app.
Is it Ok to deleteLater QWinWidget in its winEvent handler?
The thing is that I want all of my open Qt dialogs in My Mfc application
to be automatically deleted when the main mfc window is closed.
Since WM_DESTROY will be sent for all child windows ( and the Qt widgets too)
So I added the following code in QwinWidget winEvent handler :


QWinWidget::winEvent(MSG * message, long * result)
{
........
if(message->message == WM_DESTROY )
deleteLater();
return false;
}


Someone can comment this
Thanks
