334 Day 9 The Application Wizard even takes care of setting the short hint text for the speed buttons. Do you remember creating a speedbar by hand on Day 7, “Working with the Form Designer and the Menu Designer”? Compare that process with the process of creating the speedbar through the Application Wizard. It should be apparent that using the Application Wizard is by far the easiest way to create a speedbar. TIP Some specialty applications have a speedbar but do not have a menu. To create a speedbar with the Application Wizard, you must first have created a menu. To work around this, tell the Application Wizard that you want a menu and then build the speedbar. After the application has been generated, you can delete the MainMenu component from the application to remove the menu. Page Four: Setting the Final Options The fourth and last page of the Application Wizard allows you to set the program name, the path where the project should be stored on disk, and a few final options. Figure 9.11 shows the last page of the Application Wizard. Figure 9.11. The final Application Wizard settings. The first field on this page is where you specify the name of the application. This is not the name as it appears on the Project Options dialog box, but rather the filename that C++Builder will use to save the project. You will still need to set the application name in the Project Options dialog box. The second field is used to specify the directory where the project should be saved. If you don’t know the exact path, click the Browse button to the right of this field and choose the path from the Select Directory dialog box.
TIP Creating Applications in C++Builder You can use the Select Directory dialog box to create a directory as well as to select a directory. Click the Browse button to display the Select Directory dialog box. Enter the path for the directory you want to create and then click OK or press Enter. C++Builder will prompt you to create the new directory if the directory you entered does not exist. The bottom half of this page gives you three additional options. If you are creating an MDI application, click in the check box marked Create MDI Application. (MDI applications were discussed on Day 6, “The C++Builder IDE Explored: Projects and Forms.”) The remaining two check boxes allow you to implement a status bar and hint text for your components. When you are sure you have made all the choices for your new application, click the Next button. C++Builder creates the application based on the options you specified. C++Builder writes as much code as possible for the application. This doesn’t amount to a lot of code, but some of the basic code is already written for you. For example, if you chose a File menu, the FileOpenClick() handler has been written and looks like this: void __fastcall TMainForm::FileOpen(TObject *Sender) { if (OpenDialog->Execute()) { //-- Add code to open OpenDialog.FileName -- } } The code to execute the File Open dialog box is in place; you only have to write the code that actually deals with the returned filename. TIP After you create an Application Wizard project, you can choose Project | Save To Repository to save the project for later use. This will save you the trouble of going through the Application Wizard to create your basic application. You might want to add an About box before saving the project to the Repository. Using the wizards is fast and easy. You will still need to write the program, of course, but C++Builder gives you a head start by saving you from the tedium of creating the basic application elements. As RAD-friendly as C++Builder is overall, the wizards simplify things even more. The C++Builder wizards are sort of like RAD on RAD! 335 9
