Hi: From the api I found extjs provide some basic animation,for exmaple the fadeIn fadeOut and etc. However when I use them, I meet some problems.
I am confusing about the component of its show and hidden.
The animation is called to the Element,for exapmle,
form.getEl.fadeIn(...);
But for a component,it has a attribute of hidden,
And for a html element,it has a attribute of display,and visibility.
So what does the extjs use when we fadeOut/slideOut a Ext.Element? Also what does the extjs use when hidden a Ext.Component?
