Maybe these hints can help:
The completion box supports at the moment: Word completion, Template
completion and Identifer completion.
Word completion and Template completion collects the whole list and put them
into the ItemList.
Identifier completion is far more dynamic. There can be easily thousands of
items with long parameter lists. So adding them to the list would be far too
slow. The codetools do nearly everything on the fly. They don't for example
create strings to put into the list. They only gather code positions, and
when the user scrolls, the codetools read the information as needed.
About hints for identifiers:
I think, 'eclipse' has a nice idea: Right to completion box it puts a second
box of the same size and shows the help for each item. This has the
advantage, that you don't need the mouse and no new shortcuts.
This information is also available in lazarus. We have the fpdoc xml files.
What we need:
1. a hint window to right of the completion box.
2. the search for the fpdoc/xml path
3. the parsing of the fpdoc xml item and showing as formatted text
If someone implements 1 and 3, I will do 2.
