How can i delay a function?

I want to paint how the value change to newValue , so when the value increase a step,i want to repaint it .I use the code like this ,but it didn't work well:When the value increase ,it didn't repaint;but when the value changed to newValue, it repainted 10 times. Where was wrong? Thanks

Qt Code:

Switch view

void Board::setValue(int newValue)
 {
     int i=1;
     int oldValue=value;
     for(i=1;i<11;i++)
     {
         value=oldValue+(newValue-oldValue)/10*i;
         qDebug("%d",value);
         QTimer::singleShot(1000,this,SLOT(repaint()));
 //      repaint();
 //      sleep(1);
     }
 
 }

void Board::setValue(int newValue)
 {
     int i=1;
     int oldValue=value;
     for(i=1;i<11;i++)
     {
         value=oldValue+(newValue-oldValue)/10*i;
         qDebug("%d",value);
         QTimer::singleShot(1000,this,SLOT(repaint()));
 //      repaint();
 //      sleep(1);
     }
 
 }
