The
reactor callback functions add a substantial amount of code to your application.
This code is provided for you in the Lesson6 directory.
To add the reactor callback functions to your
program
- Copy the gpreact.lsp file from the Tutorial\VisualLISP\Lesson6 directory
to your MyPath working directory.
- Open
the GPath project (if it is not already
open), and choose the Project Properties button in the gpath project
window.
- Add
the gpreact.lsp file to your project.
- The gpreact.lsp file can reside anywhere
in the order of files between utils.lsp, which
must remain first, and gpmain.lsp, which should remain
as the last file. Move any files, if necessary, then choose OK.
- Open
the gpreact.lsp file by double-clicking
on the file name within the gpath project window.
Read through the comments in the file to help
you understand what it is doing. Note that all the callback functions
are stubbed out; the only functionality they perform is to display
alert messages when they are fired.
The
last function in the file is so important it deserves a heading
of its own.
