Brew MP 1.0.2
This function will request that a form deactivate itself -- for example, when
that form is no longer on the top of the form stack and is no longer the
visible form on the display. The form should respond in whatever manner is
appropriate for its specific needs. For example, a form that defines a
container widget (which, in turn, holds text, images and other controls)
could deactivate this container and trigger a trickle down effect of
deactivation to all the child widgets on the form.
void IForm_Deactivate(IForm *pif);
Calling IForm_Deactivate() effectively sets the FID_ACTIVE property on the
form, passing FALSE
as the current activation state.
