have you registered your event?
something like that, should do the job:
xgis.map.prototype.initialize = function(name) {
...
...
this.events = new OpenLayers.Events(this,
null,
['groupadded'],
false,
{includeXY: true});
this.events.register("groupadded", this, function (e) {
alert("group layer added");
});
};
xgis.map.prototype.addGroup = function(name) {
/* CODE FOR ADDING A GROUP */
/* Trigger when group is added */
this.events.triggerEvent('groupadded', group);
};

Betreff: [OpenLayers-Users] How to add custom events to OpenLayers-based
API?
Hi
I am woking on a GIS API built on top of OpenLayers. I have a class called
xgis.group, which represent a group of layers.
I want to add an event that can be triggered when a group is added.
For example, in the map, I have tried this without success:
xgis.map.prototype.addGroup = function(name) {
/* CODE FOR ADDING A GROUP */
/* Trigger when group is added */
this.events.triggerEvent('groupadded', group);
};
I don't know how to deal with custom-made events.
Could you lend me some help, please?
Thanks
