[OpenLayers-Dev] adding a 'begin' callback to the path handler...

[John Cole]

Ok, more handler work ☺

I’m looking to add a ‘begin’ callback to complement the ‘done’ callback for
the path handler.  Is the following the correct OpenLayer'ish way to do
this?

mousedown: function(evt) {
        // ignore double-clicks
        if (this.lastDown && this.lastDown.equals(evt.xy)) {
            return false;
        }
        if(this.lastDown == null) {
            this.createFeature();
	this.callback("begin", [this.geometryClone()]);	// <------ put call
back here.
        }
        this.mouseDown = true;
        this.lastDown = evt.xy;
        var lonlat = this.control.map.getLonLatFromPixel(evt.xy);
        this.point.geometry.x = lonlat.lon;
        this.point.geometry.y = lonlat.lat;
        if((this.lastUp == null) || !this.lastUp.equals(evt.xy)) {
            this.addPoint();
        }
        this.drawFeature();
        this.drawing = true;
        return false;
    }


Thanks,

John
