To have an overview what the selection is, and how they fit into the entire database please refer to the Element Overview chapter.

In these papers only the handler functions are explained in full details.

 

Handler Functions

The selection handler functions begin with the ACAPI_Selection_ prefix. This function family supports the access to the selection database.

ACAPI_Selection_Get
ACAPI_Selection_SetMarquee

 

General Error Codes

APIERR_NOSEL

There is no element selected

 

Notes

The above functions do not support to change the current selection of individual elements. To that refer the ACAPI_Element_Select function.

Do not forget that the selection set is database dependent. Each window has its own selection set; the functions of the Selection Manager work on the selection set assigned to the current database. Refer to the ACAPI_Database function to control the current database.
