Hello. I am trying to have XEmacs (version 21.1.9) and GNU Emacs use X Window resources correctly in my Red Hat Linux 6.2 system. But the resources they use are not (fully) compatible. As far as I know, the application class of the GNU Emacs process is "Emacs" and the application class for the XEmacs process may be "Emacs" or "XEmacs", as described in the documentation for the variable `x-emacs-application-class'. I will not set this variable because, "for the changes to this variable to take effect, it must be made before the connection to the X server is initialized, that is, the variable may only be changed before emacs is dumped, or by setting it in the file lisp/term/x-win.el" and I want to do a user configuration instead of a system wide configuration. "If this variable is nil before the connection to the X server is first initialized (which it is by default), the X resource database will be consulted and the value will be set according to whether any resources are found for the application class `XEmacs'. If the user has set any resources for the XEmacs application class, the XEmacs process will use the application class `XEmacs'. Otherwise, the XEmacs process will use the application class `Emacs' which is backwards compatible to previous XEmacs versions but may conflict with resources intended for GNU Emacs." So I added resources for both classes 'Emacs' and 'XEmacs' in ~/.Xdefaults expecting GNU Emacs uses only the first and XEmacs uses only the second. But that does not work. XEmacs insists in using the class 'Emacs'. If I remove the resources for class 'Emacs', XEmacs works correctly. It seems that XEmacs is not behaving as described in the documentation or maybe I have misunderstanded something. Any clues?
