Description
If enabled, this event is reported when the user clicks on an item in a ListView or TreeView object that has the focus, and signals the start of an edit operation. The default processing for the event is to display a pop-up edit box around the item and to permit the user to change its text.
You may disable the operation by setting the action code for the event to ¯1. You may prevent a particular item from being edited by returning 0 from a callback function. You may also initiate the edit operation by calling BeginEditLabel as a method.
The event message reported as the result of ⎕DQ, or supplied as the right argument to your callback function, is a 3-element vector as follows :
| [1] | Object | ref or character vector |
| [2] | Event | 'BeginEditLabel' or 300 |
| [3] | Item number | Integer. The index of the item. |
