title: How to detect horizontal scroll in panel (to disable vertical scroll meanwhile) in sencha touch
body: <p>we're using sencha touch for a webpage that contains five panels scrollable horizontally, all contained in a nestedList that's scrollable vertically.</p>
  
  <p>Everthing works fine but the scrolling is loose (because the page is scrollabe both ways, if the scrolling over a panel is a little inclined the whole page also scrolls )</p>
  
  <p>So what i want to do is to forbid vertical scrolling when horizontal scrolling is happening,
  How can i detect this ?</p>
  
  <p>notes :</p>
  
  <p>-I can't use a caroussel because the panel shows several items simultanously (not only one)</p>
  
  <p>-I tried to detect the scroll with jquery .scroll(), but it doesn't get triggered</p>
  
  <p>Thank you</p>
