Self


Self -> Function result

Parameter	Type	Description
Function result	Pointer	Pointer to form object (if any) whose method is currently being executed. Otherwise Nil (->[]) if outside of context

Compatibility Note

This command is kept only for compatibility reasons. Starting with version 12 of 4D, it is recommended to use the OBJECT Get pointer command.

Description

The Self command returns a pointer to the object whose object method is currently being executed.

Self is used to reference a variable within its own object method. It returns a valid pointer when it is called from within an object method or from within a project method that is called directly or indirectly by an object method.

If Self is called out of context, it returns a Nil pointer (->[]).

Tip: Self is useful when several objects on a form need to perform the same task, yet operate on themselves.

Note: When it is used in the context of a list box, the function returns a pointer to the list box or the column of the list box depending on the context. For more information, please refer to the Contextual click section.

Example

See the example for the Appendix D, Additional Information... command.
