It worked for me.. so make sure you added them to the Published section of 
TEdit. And do a make clean all. Other wise I do not know what you're doing 
wrong...

As for the GTK problem.. nobody implemented updating the GTK message with 
the new value.. So I tried.. but I am running into a few problems. 1.) 
someone switched it to use DeliverPostMessage.. BAD idea. this will mean 
that the calling routine will get closed before it ever getes a response, 
therefore the change code is never run, because there wasn't a change yet. 
2.) If the value in question is a ASCII key 1-31 it has to be translated 
back to its GTK value, and there is no such routine yet. And if it GTK 
Win32, any value has to be mapped back into its GTK value, because its 
String value is broken. I may just copy the routine to convert a GTKKey into 
its char value, and invert it to do the opposite. If I can do this, and 
switch KeyDown and KeyPress to use Object.Dispatch instead, this should make 
changing the key value for either of these two work.
