Thank you for your reply. 

I have read the topic, but my QVTKWidget2 already has a parent widget, so
when I call QStackedWidget's method SetCurrentWidget(), QVTKWidget2's parent
will not be changed. 

Here's my Code: 

class View : public QWidget 
{ 
public: 
        View(QWidget* parent = 0):QWidget(parent) 
        { 
                QVTKWidget2* myVtkWnd = new QVTKWidget2(); 
                QToolBar* myTB = new QToolBar(); 
                
                //... initial renderer and set background color 
                
                QVBoxLayout* vLayout = new QVBoxLayout(); 
                vLayout->addWidget(myTB); 
                vLayout->addWidget(myVtkWnd); 
                
                setLayout(vLayout); 
        } 
        ~View() {} 
}; 

class WorkSpace : public QWidget 
{ 
public: 
        WorkSpace(int rowCount, int colCount, QWidget* parent =
0):QWidget(parent) 
        { 
                QGridLayout* gLayout = new QGridLayout(); 
                for(int r=0; r<rowCount; ++r) 
                { 
                        for(int c=0; c&lt;colCount; ++c) 
                        { 
                                gLayout->addWidget(new View(),r,c); 
                        } 
                } 
                
                setLayout(gLayout); 
        } 
        ~WorkSpace() {} 
}; 

class MainWindow : public QMainWindow 
{ 
        QStackedWidget* myStack; 
public: 
        MainWindow(QWidget* parent = 0):QMainWindow(parent) 
        { 
                myStack = new QStackedWidget(); 
                myStack->addWidget(new WorkSpace(1,3)); 
                myStack->addWidget(new WorkSpace(2,2)); 
                myStack->addWidget(new WorkSpace(1,1)); 
                
                setCenterWidget(myStack); 
        } 
        ~MainWindow() {} 
        
        void SwitchTo(int index) 
        { 
                myStack->setCurrentIndex(index); 
        } 
}; 

int main(int argc,char* argv[]) 
{ 
        QApplication app(argc,argv); 
        MainWindow wnd; 
        wnd.show(); 
        
        return app.exec(); 
} 

When I call SwitchTo(int) method to change WorkSpace Layout, the QVTKWidget2
is flickering.. 

Thank you
