Using Class Completion

Class completion automates the definition of new classes by generating skeleton code for Delphi class members that you declare.

To use class completion

In the Code Editor, declare a class in the interface section of a unit. For example, you might enter the following:

Copy Code

type TMyButton = class(TButton)
    property Size: Integer;
    procedure DoSomething;
end;

Right-click on the class declaration and choose Complete Class at Cursor.
Tip: You can also invoke Class Completion by placing the cursor within the class declaration and pressing CTRL+SHIFT+C
.

Class Completion automatically adds the read and write specifiers to the declarations for any properties that require them, and then adds skeleton code in the implementation section for each class method.

Tip: You can also use class completion to fill in interface declarations for methods that you define in the implementation section.

After invoking class completion, the sample code above appears as follows:

Copy Code

type TMyButton = class(TButton)
    private
        FSize: Integer;
        procedure SetSize(const Value: Integer);
    published
        property Size: Integer read FSize write set_Size;
        procedure DoSomething;
end;

The following skeleton code is added to the implementation section:

Copy Code

{ TMyButton }

procedure TMyButton.DoSomething;
begin

end;

procedure TMyButton.SetSize(const Value: Integer);
begin
  FSize := Value;
end;

If your declarations and implementations are sorted alphabetically, class completion maintains their sorted order. Otherwise, new routines are placed at the end of the implementation section of the unit and new declarations are placed in private sections at the beginning of the class declaration.

Tip: The Finish Incomplete Properties

option on the ToolsOptionsExplorer page determines whether class completion completes property declarations.
