BeginEditLabel Event 300

Applies To: ListView, TreeView

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.
