Hi Jan,
It seems, that your code GPX.js (OpenLayers.Layer.GPX) miss something like
this.events.triggerEvent("loadend");
you should have mentioned, that you use own code for OpenLayers.Layer.GPX.

Betreff: Re: [OpenLayers-Users] Going nuts: getDataExtent
Hi Vivien,
hi all,
unfortunately it did not work.
Changed file here:
http://mybestprojects.com/data/test2/tracks_layers.html
I also would prefer the "try to register the same function but before adding
the layer" method, and NOT "within the constructor".
Thanks,
Jan

I think it's because you register your function on the event loadend but the
layer is already added and the event loadend has already been fired. So, try
to register the same function but before adding the layer. You can even do
it within the constructor with the option eventListeners. I guess it would
look like something like this but I'm not sure as I never used the gpx
format.
var lgpx = new OpenLayers.Layer.GPX("20090606175533.gpx",
"separated/20090606175533.gpx", "#FF0000",{eventListeners: {'loadend':
function(){this.zoomToExtent(lgpx.getDataExtent()) }}});
Let me know if it helps.

Hi all,
I am going nuts over not beeing able to figure out how to make getDataExtent
work for me.
This is my page NOT working yet:
http://mybestprojects.com/data/test/tracks_layers.html
I try to model after
http://oms.wff.ch/ol_track.htm (tracks work fine, just zoom in on the red
point manually.)
and
http://nuug.no/kart.shtml (automatic zoom by getDataExtent not working for
me.)
Code in question might be:
if( ! map.getCenter() ){
lgpx.events.register('loadend', map,
function(){this.zoomToExtent(lgpx.getDataExtent())});
map.setCenter(null, null);
}
or check out whole page source at
http://mybestprojects.com/data/test/tracks_layers.html
What's wrong?
Thanks,
Jan
