Reviewing the Ext JS Documentation

Page of 168

Ext JS and Sencha Touch use the same documentation system, JSDUCK. Therefore all of the things that you learned about in the prior unit regarding the Sencha class system, inheritance, methods, and runtime properties all apply to Ext JS. Ext JS does, however, contain many more visual classes than Sencha Touch, and you should take some time to review them.

The Sencha Ext JS 4 Documentation

The application that you will build during this unit uses the following view components:

Component Description
Ext.panel.Panel
A container that enables you to dock toolbars
Ext.window.Window A floating Ext.panel.Panel.
Ext.grid.Panel A table that enables you to display an unlimited amount of structured data.
Ext.form.Panel A data entry form.
Ext.toolbar.Toolbar A toolbar that is typically docked inside of a panel.
Ext.button.Button A clickable button.
Ext.chart.Chart A graphical visualization of data that is rendered using either SVG or VML.

Note that Ext JS 4 includes interactive code snippets for visual components that you can modify and experiment on directly in your browser.
