[OpenLayers-Users] How to add custom events to OpenLayers-based API?

[Arnd Wippermann]

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);
};

Arnd

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
