NAME
EvtHandler::Control - instance method
TEMPLATE
void Control(int id, int part, void * value)
SPECIFIERS
public
virtual
DESCRIPTION
Control is called on events generated by VObjects or other EvtHandlers (e.g., when a button is selected; see also method Button::DoOnItem). Control is often overridden by subclasses of the class Dialog in order to "control", i.e. react to the selection of a dialog item (e.g. the method FindDialog::Control). The default implementation passes the events to the next handler.
Compare this with the method SendDown and the method Object::Send.
Method is often overridden.
