title: How to set the scroll position in ui::ScrollView programmatically?
body: <p>Say I have a scrollview whose contentSize is the size of the visible screen</p>
  
  <p>Eg:</p>
  
  <pre><code>Content Size = 320 x 480
  InnerContainer = 900 x 480
  </code></pre>
  
  <p>How can I set the scroll position programmatically ? For example, if there is an object at (400,100), how would I programmatically scroll the view so that the object is visible ? </p>
  
  <p>There seems to be methods for setting the scroll bar position, but I don't think that actually scrolls the view.</p>
  
  <p>I am using cocos2d-x v3.10</p>
