Ext.Component.findParentByType (supporting inheritance seach)

[plalx]

The current findParentByType method doesn't support inheritance search.
There are many cases where it is usefull to be able to find a parent by its parent class.
Here's a replacement for the native Ext.Component.findParentByType method.
This method is supporting inheritance search for class names and xtypes.

Ext.override(Ext.Component, {
 findParentByType: function(type){
  if (Ext.isFunction(type)){
   return this.findParentBy(function(p){
                return p instanceof type;
            });
  } else {
   return (Ext.isFunction(Ext.ComponentMgr.types[type]))? 
    this.findParentByType(Ext.ComponentMgr.types[type]): 
    null;
  }
 }
});
