HI,
I want to write a small Delphi IDE Expert for D2007-D2009 (aka. Galileo IDE) in order to show a window with a TMemo instance on it, with all the component names
I did my first OTA with help of these links:
Erik's Open Tools API FAQ and Resources (The author of GExpert)
Delphi Open Tools API from Jim Kueneman - Mustangpeak
Delphi Open Tools API from RayRay Lischner
They are not updated to the latest versions, but they will you good start point and most of the code will work with the last version, I tried them with D2007.
There are links to articles describing how to write an OTA plug-in here: http://delphi.about.com/od/objectpascalide/a/wizardsexperts.htm
