This application uses the library of routines of the above name, which
provide an easy way of genereating a Wimp Program.
I recommend this system which can be obtained from APDL the DataFile
or other PD Libraries.
This program has been written using the routines supplied with the EvntShell library which is copyright Paul Hobbs.
EvntShell is a starting point for developing your own applications that run under the RISC-OS wimp system. The EvntShell library contains code to handle most of the 'Events' (i.e. opening a menu, closing a window etc) that can occur, and all your application has to do is inform the library what it should do when certain events occur. For example a menu can be attached to a window or to an icon - the library will open the menu for you (in the correct position!) when the <MENU> button on the mouse is used.
Normally writing a wimp application is a very complex business, involving much reading of the Programmers Reference Manuals, magazine articles and examining other applications. The aim of the EvntShell library is to reduce the need for this and to enable the speedy creation of easily maintained and robust applications.
