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.
