Hi Guys,
This totally has me beaten :'( any help would be fantastic. I've tried to
hack the Hover handler and a few other ways but everything leads to a dead
end.
The Measure control has two events, EVENT_TYPES: ['measure',
'measurepartial'] . The measurepartial is triggered from a (single) click
(note sure how this actually works, something todo with handlers?). There is
also an 'measure' that is triggered from a double click (just as unsure).
How can I implement a 3rd event 'measurehover'? Basically I want to give
someone the ability to see "how far this click will measure, if you click
here".
This probably comes from the fact I don't understand (prototyping too well)
and this code in Measure.js...
initialize: function(handler, options) {
// concatenate events specific to measure with those from the base
this.EVENT_TYPES =
OpenLayers.Control.Measure.prototype.EVENT_TYPES.concat(
OpenLayers.Control.prototype.EVENT_TYPES
);
OpenLayers.Control.prototype.initialize.apply(this, [options]);
this.callbacks = OpenLayers.Util.extend(
{done: this.measureComplete, point: this.measurePartial},
this.callbacks
);
// let the handler options override, so old code that passes
'persist'
// directly to the handler does not need an update
this.handlerOptions = OpenLayers.Util.extend(
{persist: this.persist}, this.handlerOptions
);
this.handler = new handler(this, this.callbacks,
this.handlerOptions);
},
Thanks, it's really appreciated :)
