[OpenLayers-Dev] Constructor and functions of the same class

Forget it !


I got the answer. The context of "this" is Measure object.


The new question is: How can I access a function in EditingTolbar.js with a value of longitude var in new line


layer.events.register("beforefeaturemodified", controls[1], function(e){var longitude = this.getBestLength(e.feature.geometry)});


I would like to pass "longitude" to handleMeasurementsPartial: function(event) {...} 


In other words, how can I call the father (superclass) of Measure ? In this case is EditingToolbar.


Thank's again.

I added the fllowing lines into the initialize function of the EditingToolbar class:


Controls[1] = new OpenLayers.Control.Measure(OpenLayers.Handler.Path, OpenLayers.Util.extend({displayClass: 'olControlDrawFeaturePath', title:_("Longitude")}, measureOptions));


layer.events.register("beforefeaturemodified", controls[1], function(e){this.mesurar(e.feature.geometry)});



and bellow the function:


          mesurar: function(g) {




When I execute it, it generates the error: "this.mesurar is not a function"


Why the constructor don't understand mesurar as a function of his class?


Thank's a lot
