Migrating from Globus to JVCL 3.5



Migrating your applications from previous versions of JEDI VCL


Introduction
Following the release of JVCL 3.00 and an overhaul of the code in
Globus components, it has been decided that they should be merged into
the main JVCL to avoid maintenance issues and duplicate bug fixing.
Before undergoing this migration, you must have undergone the one
mentionned in the migrating page, since it
describes how to move from the original Globus to the JVCL 3.00
codebase.
 
Once this is done, and you have installed the latest JVCL, you will
have to manually edit your source files to ensure the required changes
are done. 
 
Please note that although the document refers to "Delphi" in several
places, the instructions applies equally to other versions of Borland
GUI's (like C++Builder and Kylix) unless the text specifically says
otherwise.

Components list
Here is the list of Globus components alongside with their JVCL
replacements. As this is still work in progress, those which mention
"not done yet" have not been looked after just yet.
