Controlling Visibility and Activation Status 

You can affect the way self-defined functions operate:

·        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 you want to prevent the user from performing this function, you can deactivate the UI element.

To deactivate or activate a UI element for a function object, you use the methods belonging to the class of your UI element.

Methods Relating to the Activation Status of Function Objects

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

Showing and Hiding Functions

You can hide the UI element for a function in two ways:

·        VISIBILITY-NONE

The UI element is invisible. The elements in the toolbar that are placed next to the function simply move up and there are no gaps in the toolbar.

·        VISIBILITY-BLANK

The UI element is invisible but the space it occupied remains empty. Elements in the toolbar that were next to the function keep their former positions.

To show or hide a UI element for a function object, use the methods of the class CL_SALV_WD_FUNCTION.

Methods for Hiding/Showing Function Objects

Function	Method
Show/hide function object	SET_VISIBILITY
Get visibility	GET_VISIBILITY

Hiding, Showing, and Deactivating the Toolbar

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

Methods Relating to the Activation Status and Visibility of the Toolbar

Function	Method
Activate/deactivate toolbar	SET_ENABLED
Get activation status	GET_ENABLED
Show/hide toolbar	SET_VISIBILITY
Get visibility	GET_VISIBILITY
