Objects
The objects of a table structure are the screen elements which the user can select and edit. These can be areas or contents of varying size, depending on the table structure and technical possibilities. Typical objects of a table structure are individual cells, entire lines or an entire column. "A line" here means an entire logical line - that is, both physical lines for tables with two lines per record.
Select
To
select an object means to emphasize an object to be acted upon or an action to be performed. The object will be affected by any action the user initiates subsequently, e.g., the user chooses the Delete function.The Windows File Manager is a good example: If the user clicks on a file, the file is selected. To perform a function on the selected file (e.g. to delete the file), the user has to choose a menu option (here, Delete) (see
Object-Oriented User Interface).Deselect
The term used in the R/3 System for cancelling a selection is
deselect .Types of Selection
Depending on the task to be performed, the user can use a specific type of selection from a table structure. Selection may be classified as single or multiple. If only
one item can meaningfully be selected, we talk about single selection . If several items can be selected simultaneously, we talk about multiple selection .
