Isah Script Events

Description

An event is a a mechanism that links an occurrence in the system (such as a user action, a change in focus, or the updating of data) to a piece of code that responds to that occurrence. From a script developer's perspective, an event is just a name related to a system occurrence, such as OnClick, to which specific code can be attached. For example, a push button called Button1 has an OnClick event. The responding code is an event handler. An event always complies to a predefined signature. The event handler must correspond with this signature. Most components offer a number of standard events. An example of this is the OnClick event. In addition, some types of components can include specific events.

In this Help file, events are documented as follows:
