   其它，window2和3一样！！
  
  
  
  
  
  
  
  

   
   
   
    
  
  
  
  
  
  
  
  

   
   
   
   再看主窗口

    ui(new Ui::Widget)

    list1 = new QListWidget(this);
    list1->insertItem(0,"window1");
    list1->insertItem(1,"window2");
    list1->insertItem(2,"window3");
    window1 *win1 = new window1;
    window2 *win2 = new window2;
    window3 *win3 = new window3;
    stack = new QStackedWidget(this);
    stack->addWidget(win1);
    stack->addWidget(win2);
    stack->addWidget(win3);
    QHBoxLayout *mainLayout=new QHBoxLayout(this);
     mainLayout->setMargin(5);
     mainLayout->setSpacing(5);
     mainLayout->addWidget(list1);
     mainLayout->addWidget(stack);
     mainLayout->setStretchFactor(list1,1);//设置宽比，这里为1：3
     mainLayout->setStretchFactor(stack,3);
    connect(list1,SIGNAL(currentRowChanged(int)),stack,SLOT(setCurrentIndex(int)));
}
Widget::~Widget()
{
    delete ui;
}
 
   
   
   
   
效果：
   
   
   
   
 
   
   
   
   
    
    
    
    

     
     
     
      
    
    
    
    
 
    
    
    
    

     
     
     
     
 
       
     
 
     
     
     
     
    
    
    
    
    
    
    
    

     
     
     
      
    
    
    
    
 
    
    
    
    

     
     
     
     
    
    
    
    
    
    
    
    

     
     
     
      
    
    
    
    
    
    
    
    

     
     
     
     最后，QStackedWidget,一般和QCombox和QListWidget一起使用
