<h1>goog.fx.Dragger</h1>

<p>This demo shows how to use a dragger to capture mouse move events. It tests
that you can drag things outside the window and that alerts ends the dragging.

<h2 id=test onclick="alert('Click')">Drag me</h2>
<pre id=out>Status</pre>

<div id=stopper onmouseover="alert('Stop!')">Drag over me to generate an
alert</div>

<script>

function update(e) {
  print(e.clientX + ', ' +  e.clientY);
}

function print(s) {
  document.getElementById('out').innerHTML = s;
}

var testEl = document.getElementById('test');

goog.events.listen(testEl, goog.events.EventType.MOUSEDOWN, function(e) {

  var d = new goog.fx.Dragger(testEl);
  d.addEventListener(goog.fx.Dragger.EventType.DRAG, function(e) {
    update(e);
  });
  d.addEventListener(goog.fx.Dragger.EventType.END, function(e) {
    print('finish');
    d.dispose();
  });
  d.startDrag(e);
});
