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!
