title: Detecting Drag and Drop and detecting long press (XNA or as3)
body: <p>i am trying to implement a drag and drop behaviour for an object, i need to register when the touch is being pressed and after moving it a bit it should start dragging.</p>
  
  <p>unfortunately i am using a custom framework that is implemented in C# and it's something like XNA.</p>
  
  <p>How would you do it on XNA? </p>
  
  <p>(it's for an android tablet) .</p>
