We've covered Ext.Fx
and the other animation techniques that Ext JS offers in depth, now. But we've still got a few more features to cover when it comes to showing off with the framework. There are a number of Ext classes that provide a little extra sparkle to the top of the standard solutions. We've got LoadMask
that allows you to mask off a portion of the screen while it's being refreshed, and QuickTip
that offers a rich, configurable tooltip system.
These classes open up a new range of options when it comes to creating compelling user-experiences, and we're going to examine them in detail over the next few pages. A key feature of each is that they are reasonably simple to use, which is partly the reason why you'll want use them in many of your Ext JS applications.
