The Window Manager is designed to simplify the task of producing programs to run under a WIMP (Windows, Icons, Menus and Pointer) environment. The Manager itself is usually referred to as the Wimp. programs that run under the Wimp are often called tasks, because they are operating under a multi-tasking environment.

The Manual contains the following main sections:-

Introduction to the Window Manager
Core Concepts
The Window Manager environment
Memory Management
The WindowScroll module
Error Handling

When the Window Manager first appeared in 1987, it was a new and novel concept: now these are almost universal in modern OSes.

The Window Manager is an important part of RISC OS because:

- It provides a simple to use graphical interface, that makes your applications more accessible to a wider range of users.

- It also provides the means for you to make your applications run in a multi-taksing environment, so that they can interact with each other, and with other software.

The manual also gives guidelines on how your applications should behave so that they are consistent with other RISC OS applications.
