ItemDblClick Event 342

Description

If enabled, this event is reported when the user double-clicks a mouse button when the mouse pointer is over an item in a ListView or TreeView object. This event is reported for information only and may not be controlled in any way using a callback function. Generating the event with ⎕NQ, or calling it as a method, has no effect.

The event message reported as the result of ⎕DQ, or supplied as the right argument to your callback function, is a 6-element vector as follows :

`[1]`	Object	ref or character vector
`[2]`	Event	`'ItemDblClick'` or 342
`[3]`	Item number	Integer. The index of the item.
`[4]`	Mouse button	Integer.
`[5]`	Shift state	Integer. Sum of 1=shift key, 2=Ctrl key, 4=Alt key
`[6]`	Position	Integer. Indicates the position of the mouse-pointer within the item. It is either 2 (over the icon), 4 (over the label), 8 (over the line), or 16 (over the symbol).
