  This is my last Question.<br></p>
  
  <p>There is another problem,when markers become MarkerClusterer i set a click event to show all marker avg and show on infowindow.<br></p>
  
  <p>And,my Question is Can <strong>MarkerClusterer have a long click or double click</strong>?<br></p>
  
  <p>I mean double click and zoom in like MarkerClusterer click or long click then show infowindow,Because I need to zoom in,and After zoom in how to hide infowindow?</p>
  
  <p>My code in the link.</p>
  
  <p>By the way I try to give markerclusterer "dblclick",like this</p>
  
  <pre><code>        markerCluster = new MarkerClusterer(map, markers_Select, mcOptions);
          google.maps.event.addListener(markerCluster, 'dblclick', function(cluster) {
          var info = new google.maps.MVCObject; 
          info.set('position', cluster.center_); 
          var allmarke = cluster.getMarkers(); 
          var titles = "";
          var total = 0;
          for (var i = 0; i &lt; allmarke.length; i++) {
              total += parseFloat(allmarke[i]._myValue); 
          }
          titles = "avg：" + (total / (allmarke.length)).toFixed(2);
          g_infoWindow.setContent(titles);
          g_infoWindow.open(map, info);
          });
  </code></pre>
