350Chapter 16Getting in the Swing of Things: Designing a GUI for BudgetProFigure 16.4 BudgetPro GUI: viewing subaccountsFinally, Figure 16.4 is a look at the main GUI window for BudgetPro onceseveral accounts have been constructed.There is more to describe, but let’s walk through the code that builds thisGUI and explain the parts as we go. The complete listing is available online athttp://www.javalinuxbook.com. We’ll make reference to the line numbersof the listing in Appendix B, but sometimes we’ll show excerpts of the code aswe go. You might find it handy to have a listing of the code (on paper or inyour browser) as you read the next several sections.16.7.1 OverviewWe divide the work between two GUI classes: one for the main window andthe other for the dialog that will appear when we want to create a new subaccount.All of the other GUI elements will be either existing Swing classes ortheir extensions as anonymous inner classes in our code. (More on those later.)So that means that we have four of our own classes that we’re workingwith: two from the core of our application, Account and User, and two fromthe GUI side of things, BudgetPro and AcctDialog. This will be reflected inthe package structure; we’ll put BudgetPro and AcctDialog into thenet.multitool.gui package. This will effect both the location of the source
