IndexChanged Event 210

Applies To: Grid

Description

If enabled, this event is reported when the value of the Index property of a Grid has changed as a result of user interaction. The event is reported after the Grid has been scrolled. You may not modify or nullify the operation with a 0-return callback and you may not call IndexChanged as a method or generate this event using ⎕NQ. To cause a Grid to scroll, use ⎕WS to set its Index property.

The event message reported as the result of ⎕DQ, or supplied as the right argument to your callback function, is a 4-element vector as follows :

[1]	Object	ref or character vector
[2]	Event	'IndexChanged or 210
[3]	Row	Integer.
[4]	Column	Integer.
