Simon,
That's a good idea. Even better, if the selection model and
SelectFeature control both allow multiple features selection, you could
loop through all feature and extent the bounds to zoom to all selected
features. Also, instead of looping through the records, one could also
loop through the selected features of the vector layer. Both are okay.
Regards,
Alexandre

Hi Mike & Alexandre,
a problem could be that everytime, you selected a feature the event
gets triggered. I think a better way to solve this, is to add a
additional button inc. handler, something like this maybe:
bbar: [{
xtype: 'tbbutton',
cls: 'x-btn-text-icon',
tooltip: "Zoom To",
icon: '../images/database_go.png',
handler: function(){
gridPanel.getSelectionModel().each(function(rec) {
var feature = rec.get("feature");
var bounds =
feature.geometry.getBounds().toBBOX();
map.zoomToExtent(new
OpenLayers.Bounds.fromString(bounds));
});
}}]
Best regards,
Simon

Hi Mike,
Here's something you could do : listen to the vector layer
"featureselected" event to zoom to the extent of a feature selected
either from a click or row in the grid. Here's how it should look
like (using the example) :
vecLayer.events.on({
"featureselected": function(e) {
this.map.zoomToExtent(e.feature.geometry.getBounds());
},
"scope": vecLayer
});
If you don't want the map to zoom to the max zoomed in level when
selecting a Point feature, you could manage them differently by
detecting the type of geometry first then do a "map.setCenter(lonlat,
zoom)" instead and define your own zoom level when selecting points.
Best regards,
Alexandre

Greetings, I'm fairly new to GeoExt and OpenLayers and I was
experimenting with the example "Grid with Features"
http://api.geoext.org/1.0/examples/feature-grid.html. I'd like to
zoom or pan to a feature when the feature is clicked on the grid.
I've had success with zooming to a feature with OpenLayers but I
have no idea how to bind that click to an OpenLayers function. Any
help in the form of an example or reference would be appreciated.
Mike
