events with Geomap - How to change from World view to Country View.

[Marcel Olmo]

Hey guys, I'm a newbie here in google's geomap stuff.

I'm trying to combine/merge both examples you can find on the
documentation page :

http://code.google.com/intl/es-ES/apis/visualization/documentation/gallery/geomap.html

As you can see, there is a world map example with countries and
another one with US cities.

My idea is, if I have the world map, and click inside the Us, get into
the markers view and change the region to US.

But by know, I've been trying this and it's impossible.

I've tried adding some event listeners with 'regionClick' or
'zoomOut', but it didn't work.

Somethins like this :

var options = {};

google.visualization.events.addListener(
_this.geomap , 'regionClick', function(e) {
alert(e['region']);


});

If

[Marcel Olmo]

options['region'] = e['region'];
options['dataMode'] = 'markers';
});

.....

this.geomap.draw(data, options);


But I don't get what's happening.

Could somebody help me with these stuff ??

Many thanks in advance!!!!!

Is this resolved ?

I could only get regionClick to work when displayMode is set to 'regions'.  When set to 'markers', the event isn't fired...  The geochart doc hints at this in the section on event listeners:  "This will not be thrown for the specific country assigned in the 'region' option (if a specific country was listed)."

In order for the regionClick even to be fired, the enableRegionInteractivity option must be set to true. In marker mode, it is set to false by default, so everything should work if you just set that option.
