How do you access them in lua, using the names listed there doesn't work, how can the wiki be missing something so fundamental?
You would think for example, it would be TextBufferControl:AddMessage(), but it's not, it's CHAT_SYSTEM:AddMessage().
Specifically I'm looking for EditControl - any ideas?
Controls are just object types. Frames, labels, buttons, etc. TextBufferControl is a TYPE of object that you need to create (or access one that the game already created, like CHAT_SYSTEM) before you can call :AddMessage() on it.
