SubForm

Description

This event is generated when the user activates a particular SubForm that is the child of an MDIClient. This occurs when the user clicks the left mouse button in the SubForm or selects it from the menu nominated for this purpose (see MDIMenu property). You may also call MDIActivate as a method.

Note that this event is reported after the action has taken place and cannot be disabled by returning 0 from a callback function or by setting its action code to ¯1.

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	'MDIActivate' or 42
[3]	Object name	character vector

Note that the 3rd element of the event message is either an empty vector or contains the name of the SubForm that was previously the active one in the same MDIClient.
