Using Designer Designer is the tool for designing user interfaces that comes with Qt. This section shows you how to use Designer to build the list dialog. Then you learn the specifications for the editing dialog so you can put it together yourself. Let’s begin by starting Designer. You see the dialog shown in Figure 2-2. For the list dialog, choose to create a dialog with the buttons at the bottom and click Create. 35 36 CHAPTER 2 ■ RAPID APPLICATION DEVELOPMENT USING QT ■Tip If you are running Windows, you can start Designer by selecting it from the Start menu or by starting the Qt command prompt and then typing designer at the console.

So a good starting point when developing an application is to identify the actions that the user can take through the UI shown in Figure 2-1. ■Tip The actions identified here are very much like use cases in the Unified Modeling Language (UML), which means that the two approaches are very compatible. CHAPTER 2 ■ RAPID APPLICATION DEVELOPMENT USING QT • The first action is to start the application. When this happens, the list dialog is shown. • From the list dialog, the user adds a new item. This shows an empty editing dialog.

Figure 2-18 shows the dialog after the changes. Table 2-1.
