Hi,

This is what Gnus does when a user clicks the mouse-3 on a MIME
part button in the article buffer:

(require 'gnus-art)
(popup-menu gnus-mime-button-menu)

I get a box that seems to be a menu but no text is displayed in it.
The issue arises on only Lucid Emacs (i.e., configured with the
`--with-x-toolkit=lucid' option).  I tried GTK Emacs and verified
it works.  Or do I miss something?

emacs -Q -l gnus-art
(popup-menu gnus-mime-button-menu)

works for me with a Lucid build of the current trunk.

Does it happen when you start emacs with -Q?  Does it work with another font, i.e.

% emacs -Q -xrm 'Emacs*popup*font: fixed'

for example.  What is your default font?

Uhm, I couldn't reproduce it today.  The menu is displayed properly
with text.  Now I'm in the office and use Emacs that I built Friday
on Cygwin under Windows XP.  I'll try it again on Fedora 14 in home
about 14 hours later.

It works.  But `emacs -Q', `emacs -q' and even `emacs' also work
today. :<

> What is your default font?

I don't know.  I have no personal X resource in both the platforms
because I want Emacs that is vanilla as much as possible when
testing.  Moreover some X resources conflict with XEmacs, IIRC.
So, all the fonts I use normally are set in the ~/.emacs file.
I seem to have no means to customize the menu font as for at least
Lucid Emacs, though (the font for the `menu' face doesn't seems to
be used for popup menus).

On Cygwin, I noticed the font used for the text varies by a way to
launch Emacs.  The font looking like `fixed' is used for the popup
menu if I start Emacs from the command line in xterm, but the one
looking like Helvetica is used if I start Emacs from Cygwin's root
menu.  On the analogy of this, I guess a font that doesn't provide
ASCII text is chosen for some reason when a popup menu is displayed
with no text.

Anyway the solution will probably be to have an X resource for
the default font.  Any other thought?

I'm home.  I verified it reproduces with the latest Emacs 24.0.90
(I built it minutes ago) on Fedora 14.  Here's a screenshot:

This happens with `emacs -Q', but setting the `Emacs*popup*font'
resource with any font that provides ASCII characters solves it.
Though it might not be an Emacs bug, I suspect there's something
that leads Emacs to choose a wrong font when there's no X resource
for `Emacs*popup*font'.

Hello.

The font Emacs chooses can be one of three:

If you have Xft (antialiased fonts) and one of Xsettings/Gsettings/GConf
it chooses the normal font for your desktop.  You can see what it is by 
calling the lisp function font-get-system-font.

Otherwise, it uses Sans-10 if you have Xft, or the default Xt font if not.

Thanks.  (font-get-system-font) returns "Monospace 10" in both
Cygwin and Fedora 14.  But `popup-menu' shows text in a menu on
Cygwin currently whereas it doesn't on Fedora 14.  Is there another
way to test them?

I'm sorry for the lazy response.  (I wish I could use the both
systems in the office and home.  Well, maybe I should have Cygwin
in home as well...)
