Customize Application ShortCuts

Posted on 2002-06-04

Last Modified: 2010-04-04
I have an ActionList with my various commands and their corresponding ShortCuts.

I am trying to make a dialog that loads all the actions from the ActionList (along with their associated images, captions, and shortcuts) into a ListView so that the user can customize the shortcuts for each action.

Can anyone show me an example of how to do this? I am using Delphi 4/5 if that matters.


Thanks
