WARNING
When you add an object to the Object Repository, C++Builder makes
an entry in the Object Repository file that describes the object. This
information includes the pathname where the form and source file for
the object are located. If you move or delete an object’s form or source
file, you will not be able to use the object from the Object Repository.
Adding Projects to the Object Repository
Adding projects to the Object Repository is not much different from adding individual
forms. To add a project to the Object Repository, choose Project | Add To Repository from
the main menu. The Add To Repository dialog box is displayed just like it is when you’re
adding objects to the Repository, except the Forms list box is not displayed. Fill in any
required information (Title, Description, Author, and so on) and click OK, and the project
is added to the Repository.
After you are familiar with C++Builder, you should create an application shell that has the
features you use most often in your applications. Each time you start a new standard
application, make a copy of the shell from the Object Repository. This way you can have your
menus, speedbar, About box, and other standard dialog boxes all set up and ready to go in
a matter of seconds. Once the new application has been created, it can then be modified as
with any project. You can add new forms, delete any unwanted forms, and so on.
Object Repository Housekeeping
You can manage the pages and objects in the Object Repository by using the Object
Repository configuration dialog box.
To view the Object Repository configuration dialog box, choose Options | Repository from
the main menu or, if you have the Object Repository open, choose Properties from the Object
Repository speed menu. The configuration dialog box is displayed, as shown in Figure 9.4.
This dialog box allows you to delete objects and pages from the Object Repository, move
objects from one page to another, change the order of pages in the Object Repository, and
more. The list of pages in the Object Repository is displayed in the list box labeled Pages on
the left side of the dialog box. When you select one of the pages in the Pages list, the list box
on the right (labeled Objects) displays the objects contained on that page.
