    Unanswered: I can't use Ext.Util.TextMetrics ... why ?


    I'm trying to use the methods form Ext.util.TextMetrics,

    code:
    Code:
      this.setTitle("Hi!");
      var width = Ext.util.TextMetrics.getWidth(this.title);
      this.setWidth(width);


    on chrome debugger:


    Code:
    >"Ext.util.TextMetrics: function () {"

    but when expand that function do nothing... can't invoke any method, i got a Exception problem on that code:




    and this is the exception that throw:




    Code:
    extjs/src/chart/Tip.js?_dc=1347004442226:86
    Uncaught TypeError: Object function () {                return this.constructor.apply(this, arguments);            }

    on console, expanded:

    Ext.util.TextMetrics is a class, not an object, and getWidth() is not a static method. So you should create an instance from it. Example:
    Code:
    var tm = Ext.create('Ext.util.TextMetrics');
    console.log(tm.getWidth('123456789'));
