Events – ActiveX Object
WDterm events occur when a specific condition is met. When an event is "fired", an event handler function
in your application is called.
Though the details of exactly how it is done varies from one programming environment to the next, the
source code skeletons for the various event handlers are automatically generated and inserted into your
source code for you. See the samples for more specific information.
Each event passes relevant information to your event handler function. The only event that does not pass
any data is
OnTermBaseRegister
. All others pass at least the Terminal ID on which the event occurred.
OnTermData
also passes the data that was keyed or scanned into the terminal.
