60 | /* This sucks: this is the first default that x-faces.el tries. This won't |
61 | be used unless neither the "Emacs.EmacsFrame" resource nor the | |
62 | "Emacs.EmacsFrame" resource is set; the frame | |
63 | may have the wrong default size if this font doesn't exist, but some other | |
64 | font that x-faces.el does. The workaround is to specify some font in the | |
65 | resource database; I don't know a solution other than duplicating the font- | |
66 | searching code from x-faces.el in this file. | |
67 | ||
68 | This also means that if "Emacs.EmacsFrame" is specified as a non- | |
69 | existent font, then Xt is going to substitute "XtDefaultFont" for it, | |
70 | which is a different size than this one. The solution for this is to | |
71 | make x-faces.el try to use XtDefaultFont. The problem with that is that | |
72 | XtDefaultFont is almost certainly variable-width. | |
73 | ||
74 | #### Perhaps we could have this code explicitly set XtDefaultFont to this? | |
