More GUI and the Visual Editor

Abstract

This chapter will explore GUI components in more depth. We will introduce the concepts behind listeners and event driven programming. We will then, show how to implement listeners, use them to solve the "window closing" problem (from the previous chapter), and enable buttons to perform functions. In addition, we will show, in more detail, the advantages of inheritance (i.e., specialization), especially how it decreases the amount of source code that must be written by the programmer. Finally, we will introduce RAD’s Visual Editor (VE). VE is a very productive tool for generating GUI classes. Through an extensive tool bar and drag and drop, VE provides a GUI for defining GUIs!
