Chapter 4. Core UI components
This chapter covers
- Exploring the panel
- Implementing panel content areas
- Displaying an Ext.Window
- Using Ext.MessageBox
- Creating tab panels
When developers start to experiment or build applications with Ext JS, they often start by copying examples from the downloadable SDK. Although this approach is good for learning how a particular layout was accomplished, it falls short in explaining how the stuff works, which leads to those throbbing forehead arteries. In this chapter you’ll learn about core topics that are the building blocks of developing a successful UI deployment.
You’ll also dive into how the panel works and explore the areas where it can display content and UI widgets. You’ll then explore windows and the message box, which float above all other content on the page. You’ll also learn about tab panels in this chapter.
