GetTipText Event 325
Applies To: ListView, TreeView
Description
If enabled, this event is reported by a TreeView or ListView object just before it displays a tip for a specific row.
The event message reported as the result of ⎕DQ, or supplied as the right argument to your callback function, is a 5-element vector as follows :
[1] |
Object | ref or character vector |
[2] |
Event | 'GetTipText' or 325 |
[3] |
Item index | Integer ( ⎕IO dependent) |
[4] |
SubItem index | Integer ( ⎕IO dependent, currently always equal to ⎕IO ) |
[5] |
TipText | The text to be displayed. |
Modifying and returning the 5th element of the argument to the callback function allows the application to change the displayed tip.
The text can be set to a character array of rank 2 or less.
The default processing for the event is to display the default tip (if there is one).
The associated callback is run immediately while the windows notification is still on the stack. See High-Priority Callback Functions.
