Extjs学习笔记之五 一个小细节renderTo和applyTo的区别
render : function(container, position){
if(!this.rendered && this.fireEvent('beforerender', this) !== false){
if(!container && this.el){
this.el = Ext.get(this.el);

}else{
position = Ext.getDom(position);
}

this.onRender(this.container, position || null);
if(this.autoShow){
this.el.removeClass(['x-hidden','x-hide-' + this.hideMode]);
}
