◆ embedSubWindow()

void QGraphicsProxyWidgetPrivate::embedSubWindow ( QWidget * subWin)

Embeds subWin as a subwindow of this proxy widget. subWin must be a top-level widget and a descendant of the widget managed by this proxy. A separate subproxy will be created as a child of this proxy widget to manage subWin.
