ttf can't work on GNU Emacs(X-window)?

[Richie]

Hi guys,

I have this problem for a long time. I want to use andale mono ttf font
in Emacs, but I don't know how to do in order to let emacs know this
font exists. When I put the andale mono font file into the
/usr/share/fonts/blahblah, other software can recognize it ( the reason
is that they support gtk2?). However, my favourite editor don't accept
it no matter where I set it(in .Xdefaults or .emacs). From some web, I
know emacs(xwindow) can only use the fonts which the "xlsfonts" command
shows. So my question now is how to let xlsfonts accept the ttf fonts.

Now I only use emacs -nw, for I can set the term font to andale,-.-.
