This book provides Basic programmers with a complete introduction to all the techniques involved in writing multi-tasking Wimp programs to run within the RISC OS Desktop environment. No prior knowledge of the Wimp is assumed and the tutorial style of the book will enable all programmers to understand the concepts involved and to develop their skills in writing high quality programs for Acorn's RISC machines.
An accompanying disc, containing all the example programs described in the book, and additional applications, is available for £4.95 (inc. VAT) direct from the publishers.
The authors are both well known within the Acorn community. Dr Lee Calcraft is co-founder of BEEBUG, currently co-editor of RISC User, and author of RISC Developments' popular DeskEdit and ArcScan packages. He also runs a programming consultancy. Alan Wrigley is a former Technical Editor of RISC User, now a freelance contributor, and author of an expanding range of Desktop applications marketed under the name of Rheingold Enterprises. Both authors have extensive experience of programming in general, and the RISC OS Wimp in particular.
