Hi All,
I cannot get code assist to work at all in header files. When I hit
CTRL+SPACE, I just get garbage. If I move the code to a cpp file, it
works fine. Can someone else confirm this? I could not find a bug on it.
thanks,
Barry

Code Assist looks based on binary indexer. so, source must be compiled
before using code assistance.
anyway, if you using managed project, just put the include statement
into the source contains main function. then build, then index of header
file will be build, and code assistance will work.

Anyway... so will this work if I don't use a managed project? I really
don't like the idea of including headers in the main source file.
This is quite important for anyone using a QT Designer project, because
the way QT Designer works, you typically put your GUI code in the header
file. This code gets included in a moc cpp file when you build it. So
the cpp file gets regenerated every time.
I will try what you said and see if it helps.
thanks a lot!

Yes, it would be odd, and that probably why we didn't do it that way :)
First of all, which version are you using? We've done a lot of work in
3.0 for content assist. It should be working a lot better in header files.
The main issue we've had in the past is that the content assist was
driven by the parser which needs proper build information like inclusion
paths and macro defs to parse correctly. Header files are even more
tricky since you don't build them on their own.
In 3.0 and beyond, we have and will be adding more heuristics to get by
the incomplete information.
Hope this helps,
Doug.

some more and see if I can put together a small reproducable test case.

it should work), so I sured wrong infomation. Sorry :(
I tried it again with 3.0m7, and I saw indexer working on save.
and code assistance works well on header.
what'r problems for now...?

Ok, I figured out the problem! I just don't know what to do about it. ;)
Basically, yes code assist does work for header files! Hats off to the
developers!!! Very nice!
But I have a very specific problem, and I believe anyone who has a Qt
Designer project will have the same. Maybe this will apply to other
projects as well, but it would probably be rare.
When you have a Qt Designer project, you get a .ui directory created for
you. That directory contains the generated source that Qt generates from
the GUI XML files. ( And the XML files are created from the visual GUI
editing tool. ) So you have a header and a cpp file for each window in
this directory. Those files are not touched by the developer. But
instead you have another header file outside the .ui directory that you
should modify. At compile time, your source is incorporated into the
source files in the .ui directory. Well, I don't know ALL the details,
but this is the basics and hopefully you get the idea.
So when I created the Standard Makefile C++ project from an already
existing project, the .ui directory was not included in the project
Includes. Well... you can see the directory itself, but it shows there
are no files in the directory. But files do exist!
So it seems the problem is CDT is ignoring files that are in a directory
that begins with dot. I created a Simple project with a .ui directory,
added a file and unchecked .* from filters and the files show.
However source files do not show in the C++ Project Includes.
I will gladly log a bug unless someone can tell me how to get the CDT to
recognize files in directories that begin with '.'
BTW, this does work in Visual Slick Edit v10 on Linux. It will tag the
files in the .ui directory and code assist will work in my header file.
thanks,
Barry

Well... in case anyone is following this thread, I have finally figured
out the problem. I just needed to use
#include ".ui/myheader.h" in my user modifiable header file. I didn't
have to do this in SlickEdit. As long as a file is tagged in SlickEdit,
code assist will find the symbols. So CDT's way is not bad and I am sure
it will get better over time. :) It's a little strange to include a
header within a header when the header is really the same. Huh? But this
is Qt, and it is a little different anyway. Anyway.... it works and I am
happy!
thanks for the replies!
