Well, that's seem that fontconfig is not used in your setup.
What version of qt you're using?
Hmm.. you may want to first check that whether fontconfig has correctly
find the fonts or not by 'fc-list'
It is a tools from fontconfig pkg and used to list out all fonts found
by fc-list (analog to xlsfonts in the xfont world.)
Also, I remember that sometimes ago (about half an year), one version of
fontconfig is a bit of broken in terms of regenerate font cache.
In that case, you can use something like
$ find ${fondDir} -name "fonts.cache*" | xargs rm -f
$ fc-cache

Most likely not, as I know, apps using client side fonts (Xft +
fontconfig) is different to use xfonts (Xlib's fontset) at the same
time.
I can however, like pango, using different engine, it have multiple
rendering engine (wrapper libs) for different platform, but it will not
use both at the same time.
Similarly, newer version of xterm does the same thing, you can specify
it to use client side fonts directly (by -fa -fs), OR you can use
traditional way to use fonts, but not both.

the 'local.conf' mechanism is just used to seperate per-site
configuration from distribution wide config.
For example, if inside fontconfig ebuild, we want it to have a very nice
tuned config for gentoo users, we can put the config inside
/etc/fonts/fonts.conf,
After installing fontconfig, and I'd like to do some customization, I
can add the config to 'local.conf' or ~/.fonts.conf (per site / per
user)
So both fonts.conf / local.conf / .fonts.conf can be used, depending on
the context.
Also, note that the precedence of those 'matching and edit'

I've no idea that to what extent qt3 is using fontconfig for their font
listing and matching jobs.
btw, I would like to have a look in here !

somethings before, I use something like
>>>
<match target="font">
<test name="VeraMoit.ttf"></test>
<edit name="antialias"><bool>true</bool></edit>
</match
<<<
to explicitly testing the AA for each fonts
I don't know whether I can help ur needs though !

In GTK 2.0, we need to use 'GDK_USE_XFT=1' to enable using xft for
drawing text, does qt using similar ways?

Yes, I always find those option is hardly to experiment, seems some
options is used by ft2 and some is xft, and I don't know exactly
how those options is passed through those libs. :)
Right, for me to experience qt font stuff, can you recommend me some qt
based apps which doens't have lots of dep, as my machine has no kde
setup. I hope I can find out an qt apps but no need to built those kde
libs. (as I have a PIII 650 laptop on hand..)
