Question

hello I started to learn ext
I have installed extj and I can browse examples from local host successfully

from examples

    Ext.require('Ext.chart.*');
    Ext.require(['Ext.Window', 'Ext.layout.container.Fit', 'Ext.fx.target.Sprite']);

    Ext.onReady(function () {
 //lob lob lob

it seems to me EXT is a class which has many objects where I can find ext itself?
I tried hard to find it but I couldn’t find it through these huge files
for example what Ext.chart.* means?
what the second line means?

Answer 1

Ext.require('Ext.chart.*'); means all Ext javasript files in chart folder will be included in the script. Chart.* says all files under chart hierarchy.

 - chart 
      +Axies
      +series
      +theme
      -callout
      -Chart
      -Hightlight
      -Label
      -Legend
      -LegendItem
      -Mask
      -Navigation
      -Tip
     

You can browse the chart hierarchy here.
