Controlling Visibility and Activation Status 

You can specify whether self-defined functions are used in various ways:

●     You can deactivate an individual UI element for a function.

●     You can hide an individual UI element for a function.

●     You can deactivate the entire toolbar.

●     You can hide the entire toolbar.

Activating and Deactivating Functions

If you do not want to hide a UI element, but want to prevent the user from executing its function, you can deactivate the UI element.

To activate or deactivate the UI element for a standard ALV function, you use methods from class CL_SALV_WD_FUNCTION_STD.

To activate or deactivate the UI element for a self-defined function, you use methods from the class of your UI element (see Specifying User Interface Elements).

Methods for the Activation Status of Function Objects

Function	Method
Enable/disable function object	SET_ENABLED
Get activation status	GET_ENABLED

Showing and Hiding Functions

The following two constants are available for showing and hiding functions:

●     VISIBILITY-VISIBLE

The system displays the function.

●     VISIBILITY-NONE

The system hides the function.

To show or hide a UI element for a standard ALV function, you use the methods of class CL_SALV_WD_FUNCTION_STD.

To show or hide a UI element for a self-defined function, you use the methods of class CL_SALV_WD_FUNCTION.

Methods for Showing and Hiding Function Objects

Function	Method
Show/hide function object	SET_VISIBILITY
Get visibility	GET_VISIBILITY

Showing, Hiding, and Deactivating the Toolbar

To control the activation status or visibility of the whole toolbar, you use the methods of interface class IF_SALV_WD_FUNCTION_SETTINGS (implementing class CL_SALV_WD_CONFIG_TABLE).
