Chapter 4 Explanations of Implementation Examples (Sample Tools)

These implementation examples (sample tools) in NAB Framework use the NAB plug-in for MWT (MWT Application Builder) for editing MWT.

MWT:

Similar to WIN32, Xt, GTK, and other toolkits, MWT has different types (classes) of components, and each component can create an entity, referred to as an instance, whose native value distinguishes it from other entities.

Deployed components in a parent-child relationship configure a tree and implement a GUI. A deployed instance has multiple variables, each retaining information on a status, and they are referred to as properties. The behavior of the instance can be specified or changed by setting values for these properties. An event is generated from the deployed instance when the instance is deployed again or when a property of the instance is changed. Callback processing for the event is defined as necessary, and if it is defined, the processing can be executed when the event occurs.
