[mapguide-internals] FW: [mapguide-users] patch for Mouse WheelZoom, set scale and image on loading map in Ajax.

Mon Apr 2 17:49:22 EDT 2007

Thanks for this Jason, I haven't been able to look at the users list for a bit.

Chris is looking into this and if it looks good, we'll put it in for the beta.

How invasive are these changes?  Is it something that we could add to 1.2 during the beta stages? :)

I've try to post the code in the internal list, but I don't how to register. Anyway here the code. I've applied the changes on the 1.0.2, but in the last version works fine.

Somebody who know how to do it, please e-mail me.

This patch use javascript to zoom with the wheel mouse, like in AutoCAD.

Another patch is to input in the scale bar, a scale manually. 

You can see an icon in the toolbar when the map is loading.

E-mail me with any problem.

Thank you.

In css: 
________________________________

        div.cssRefresh
        {
            position: absolute; 
            right:10px;
            top:4px;        
        }

The body seems like this. Rotating_arrow.gif is the image. You can design it or use the attached:

________________________________

<body class="Toolbar" onload="InitDocument()" leftmargin=10 topmargin=0 rightmargin=0 bottommargin=0 marginwidth=0>
    <div id="divRefresh" name="divRefresh" class="cssRefresh"><img alt="loading" src="../phpviewersample/images/common/rotating_arrow.gif"></div>
    <span id="ToolbarContent"><td></td></span>
    <div class="TextMetricsDiv" id="TextMetricsDiv"><span class="TextMetrics" id="Metrics"></span></div>
  </body>
