SubForm

Description

This event is generated when the user activates a different SubForm that is the child of an MDIClient, thereby de-activating the current one which causes this event. This occurs when the user clicks the left mouse button in another SubForm or selects it from the menu nominated for this purpose (see MDIMenu property). You may also call MDIDeactivate 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	'MDIDeactivate' or 43
[3]	Object name	character vector

Note that the 3rd element of the event message contains the name of the SubForm that has now been made the active one in the same MDIClient.
