I have solved the problem. I have changed the values for zoom from bluemarble.dgml and now works properly:<br><br>            <zoom><br>                <minimum>   700  </minimum><br>                <maximum>  2400  </maximum><br>
    <br>                <!-- describes whether you can zoom trough the levels<br>                    continuously --><br>                <discrete> false </discrete> <br>            </zoom><br><br>
My new zoom improved code: <a href="http://pastebin.com/3cLuhUWg">http://pastebin.com/3cLuhUWg</a><br><br><div class="gmail_quote">2012/5/16 marble_developer marble_developer <span dir="ltr"><<a href="mailto:marbledeveloper@gmail.com" target="_blank">marbledeveloper@gmail.com</a>></span><br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi all,<br><br>I have this code to change the zoom view when the ShowSunInZenith == true: <a href="http://pastebin.com/w0VcQB4T" target="_blank">http://pastebin.com/w0VcQB4T</a><br>
<br>The wheelEvent() method is called each time that the wheel is actioned and the value for zoom is updated but the zoom isn't changed visually.<br>
<br>Initially zoom == 700 and it changes to 701, 702, 703... or 699, 698, 687... when the wheel is actioned.<br><br>What's wrong?<br><br>Best regards.<br>
