Delphi in a Nutshell

Name

Register Procedure

Syntax

procedure Register;
begin
  ... 
end;

Description

When you write a design-time package, you will usually write a Register procedure in one or more units that the package contains. When Delphi loads the design-time package in the IDE, it searches for a procedure named Register and calls that procedure, if it exists. It calls the procedures in the order in which the units appear in the package source file.

Tips and Tricks

• The procedure name must follow the capitalization shown here: an initial capital R, followed by a lowercase egister. This restriction is unusual for Pascal, but it provides compatibility with C++ Builder, which is a case-sensitive language. You can write a package in Delphi and load it in C++ Builder, or vice versa.

• The Register procedure is optional.

• Delphi’s IDE calls the Register procedure when it loads design-time packages. If you load the same package in an application, the Register procedure is not called automatically.
