Lucid toolkit and antialiased fonts

Lucid toolkit and antialiased fonts

[Ulrich Mueller]

Hi,

with Emacs from BZR trunk (configured with --with-x-toolkit=athena
--with-xft), I can specify fonts by their fontconfig name:

    Emacs.font: Droid Sans-10
    Emacs.pane.menubar.font: Droid Sans-10

This will give me antialiased fonts both for text and in the menubar.

However, if I specify the font by its XLFD name instead:

    Emacs.font: -*-droid sans-medium-r-normal--*-100-*-*-p-*-iso10646-1
    Emacs.pane.menubar.font: -*-droid sans-medium-r-normal--*-100-*-*-p-*-iso10646-1

then the text font is antialiased but the font in the menubar is not.

Why?

It is backward compatible. If you specify XLFD names you probably wan't the 
old fonts that pre-dates anti-aliased fonts.  For the text you have the option 
to specify font backend, but the font code in Emacs is not well suitable for 
other things than faces (i.e. Lisp_Objects), and Lucid doesn't use faces.

It would be nice if we could specify font by customizing the menu face, but 
specifying a font for a face isn't trivial (simple names doesn't work), and I 
can't see how to specify aa or non-aa there.
