我正在使用this demo显示模态对话框

如果我将其用于google街景视图，我如何设置对话框的宽度：

var point = new GLatLng(svlat,svlon);
var panoClient = new GStreetviewClient(); 
panoClient.getNearestPanoramaLatLng(point,function (newPoint) {
  if (newPoint == null) {
      alert("no panorama found for this position!!");
      return;
  }
  panoramaOptions = { latlng: newPoint };
  myPano = new GStreetviewPanorama(document.getElementById("pano"),panoramaOptions);
  $('#dialogStreetView').dialog("option","maxWidth",600);
  $('#dialogStreetView').dialog('open');
  GEvent.addListener(myPano,"error",handleNoFlash);
});

HTML：

<div id="dialogStreetView" title="Street View Provided by Google... "     style="width:300px;height:300px">
    <a id="closestreet-view" name="closestreet-view" style="cursor:pointer; text-   decoration:underline" >Close</a>
    <div name="pano" id="pano" style="width: 300px; height: 300px"></div>
</div>
