28 ;;; Commentary:
|
|
|
29 ;;;
|
|
|
30 ;;; Creates three menus, "Font", "Size", and "Weight", and puts them on the
|
|
|
31 ;;; "Options" menu. The contents of these menus are the superset of those
|
|
|
32 ;;; properties available on any fonts, but only the intersection of the three
|
|
|
33 ;;; sets is selectable at one time.
|
|
|
34 ;;;
|
|
|
35 ;;; Known Problems:
|
|
|
36 ;;; ===============
|
|
|
37 ;;; Items on the Font menu are selectable if and only if that font exists in
|
|
|
38 ;;; the same size and weight as the current font. This means that some fonts
|
|
|
39 ;;; are simply not reachable from some other fonts - if only one font comes
|
|
|
40 ;;; in only one point size (like "Nil", which comes only in 2), you will never
|
|
|
41 ;;; be able to select it. It would be better if the items on the Fonts menu
|
|
|
42 ;;; were always selectable, and selecting them would set the size to be the
|
|
|
43 ;;; closest size to the current font's size.
|
|
|
44 ;;;
|
|
|
45 ;;; This attempts to change all other faces in an analagous way to the change
|
|
|
46 ;;; that was made to the default face; if it can't, it will skip over the face.
|
|
|
47 ;;; However, this could leave incongruous font sizes around, which may cause
|
|
|
48 ;;; some nonreversibility problems if further changes are made. Perhaps it
|
|
|
49 ;;; should remember the initial fonts of all faces, and derive all subsequent
|
|
|
50 ;;; fonts from that initial state.
|
|
|
51 ;;;
|
|
|
52 ;;; xfontsel(1) is a lot more flexible (but probably harder to understand).
|
|
|
53 ;;;
|
|
|
54 ;;; The code to construct menus from all of the x11 fonts available from the
|
|
|
55 ;;; server is autoloaded and executed the very first time that one of the Font
|
|
|
56 ;;; menus is selected on each device. That is, if XEmacs has frames on two
|
|
|
57 ;;; different devices, then separate font menu information will be maintained
|
|
|
58 ;;; for each X display. If the font path changes after emacs has already
|
|
|
59 ;;; asked the X server on a particular display for its list of fonts, this
|
|
|
60 ;;; won't notice. Also, the first time that a font menu is posted on each
|
|
|
61 ;;; display will entail a lengthy delay, but that's better than slowing down
|
|
|
62 ;;; XEmacs startup. At any time (i.e.: after a font-path change or
|
|
|
63 ;;; immediately after device creation), you can call
|
|
|
64 ;;; `reset-device-font-menus' to rebuild the menus from all currently
|
|
|
65 ;;; available fonts.
|
|
|
66 ;;;
|
|
86
|
67 ;;; There is knowledge here about the regexp match numbers in
|
|
|
68 ;;; `x-font-regexp' and `x-font-regexp-foundry-and-family' defined in
|
|
|
69 ;;; x-faces.el.

|
70 ;;;
|
|
|
71 ;;; There are at least three kinds of fonts under X11r5:
|
|
|
72 ;;;
|
|
|
73 ;;; - bitmap fonts, which can be assumed to look as good as possible;
|
|
|
74 ;;; - bitmap fonts which have been (or can be) automatically scaled to
|
|
|
75 ;;; a new size, and which almost always look awful;
|
|
2
|
76 ;;; - and true outline fonts, which should look ok at any size, but in
|
|
0
|
77 ;;; practice (on at least some systems) look awful at any size, and
|
|
|
78 ;;; even in theory are unlikely ever to look as good as non-scaled
|
|
|
79 ;;; bitmap fonts.
|
|
|
80 ;;;
|
|
|
81 ;;; It would be nice to get this code to look for non-scaled bitmap fonts
|
|
|
82 ;;; first, then outline fonts, then scaled bitmap fonts as a last resort.
|
|
|
83 ;;; But it's not clear to me how to tell them apart based on their truenames
|
|
|
84 ;;; and/or the result of XListFonts(). I welcome any and all explanations
|
|
|
85 ;;; of the subtleties involved...

88 ;;; If You Think You'Re Seeing A Bug:

89 ;;; =================================
|

90 ;;; When reporting problems, send the following information:

|
|
91 ;;;
|
|
|
92 ;;; - Exactly what behavior you're seeing;
|
|
|
93 ;;; - The output of the `xlsfonts' program;
|
|
82
|
94 ;;; - The value of the variable `device-fonts-cache';
|
|
0
|
95 ;;; - The values of the following expressions, both before and after
|
|
|
96 ;;; making a selection from any of the fonts-related menus:
|
|
|
97 ;;; (face-font 'default)
|
|
82
|
98 ;;; (font-truename (face-font 'default))
|
|
|
99 ;;; (font-properties (face-font 'default))
|
|
0
|
100 ;;; - The values of the following variables after making a selection:
|
|
|
101 ;;; font-menu-preferred-resolution

86
|
102 ;;; font-menu-registry-encoding
|
|
0
|
103 ;;;
|
|
|
104 ;;; There is a common misconception that "*-courier-medium-r-*-11-*", also
|
|
|
105 ;;; known as "-adobe-courier-medium-r-normal--11-80-100-100-m-60-iso8859-1",
|
|
|
106 ;;; is an 11-point font. It is not -- it is an 11-pixel font at 100dpi,
|
|
|
107 ;;; which is an 8-point font (the number after -11- is the size in tenths
|
|
|
108 ;;; of points). So if you expect to be seeing an "11" entry in the "Size"
|
|
|
109 ;;; menu and are not, this may be why.
