AT LINE-SELECTION
Other versions: 7.31 | 7.40 | 7.54
Syntax
AT LINE-SELECTION.
Effect
This statement defines an event block whose event is triggered by the ABAP runtime environment when a screen list is displayed. This is provided the screen cursor is on a list line and you select a function using the function code PICK. By defining this event block, the standard list status is enhanced automatically in such a way that the function code F2 and, with it, the double-click mouse function is associated with the function code PICK.
Note
If the function key F2 is associated with a function code other than PICK,
each double click triggers its event, usually AT USER-COMMAND
, and not AT LINE-SELECTION
.
Example
This program works with the standard list status. Selecting a line with the left mouse key triggers the event AT LINE-SELECTION
and creates details lists.
