/**
|
|
* @class Ext.ux.Exporter.Button
|
|
* @extends Ext.Component
|
|
* @author Nige White, with modifications from Ed Spencer, with modifications from iwiznia.
|
|
* Specialised Button class that allows downloading of data via data: urls.
|
|
* Internally, this is just a link.
|
|
* Pass it either an Ext.Component subclass with a 'store' property, or just a store or nothing and it will try to grab the first parent of this button that is a grid or tree panel:
|
|
* new Ext.ux.Exporter.Button({component: someGrid});
|
|
* new Ext.ux.Exporter.Button({store: someStore});
|
|
* @cfg {Ext.Component} component The component the store is bound to
|
|
* @cfg {Ext.data.Store} store The store to export (alternatively, pass a component with a getStore method)
