Qt State Machine Framework

This component adds an API for creating hierarchical finite state machines. Note that this solution is experimental and work in progress: No backwards compatibility (source nor binary) is provided.

 Please note: This component is deprecated; see the catalog.

The State Machine Framework lets you define and run state machines. It also includes tools to load or compile SCXML files.

Tested on:

• Qt 4.4, 4.5 / Windows XP / MSVC.NET 2005
• Qt 4.4, 4.5 / Linux / gcc

Unsupported platforms:

Only the tested platforms are supported, however the classes should be platform independent and are likely to work on the platforms supported by Qt.
