HideComment Event 224

Applies To: Grid

Description

If enabled, a HideComment event is generated just before a comment window is hidden as a result of the user moving the mouse-pointer away from a commented cell.

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	'HideComment' or 224
[3]	Row	integer
[4]	Column	integer

You may prevent the comment from being hidden by returning 0 as the result of a callback function.

Note that if the comment window relates to a row or column title, the value reported in element [3] or [4] of the event message is ¯1.

Invoked as a method, HideComment is used to hide a comment that has previously been displayed by ShowComment. For example, the following expression hides the comment associated with the cell at row 2, column 1.

      F.G.HideComment 2 1

If HideComment is called with an argument of ⍬, all comments are hidden.
