47
|
|

48 If LOCALE is omitted, the GLYPH's actual value for PROPERTY will be
|
|
|
49 returned. For built-in properties, this will be a specifier object
|
|
|
50 of a type appropriate to the property (e.g. a font or color
|
|
|
51 specifier). For other properties, this could be anything.
|
|
|
52
|
|
|
53 If LOCALE is supplied, then instead of returning the actual value,
|
|
|
54 the specification(s) for the given locale or locale type will
|
|
|
55 be returned. This will only work if the actual value of
|
|
|
56 PROPERTY is a specifier (this will always be the case for built-in
|
|
|
57 properties, but not or not may apply to user-defined properties).
|
|
|
58 If the actual value of PROPERTY is not a specifier, this value
|
|
|
59 will simply be returned regardless of LOCALE.
|
|
|
60
|
|
|
61 The return value will be a list of instantiators (e.g. strings
|
|
|
62 specifying a font or color name), or a list of specifications, each
|
|
|
63 of which is a cons of a locale and a list of instantiators.
|
|
|
64 Specifically, if LOCALE is a particular locale (a buffer, window,
|
|
|
65 frame, device, or 'global), a list of instantiators for that locale
|
|
|
66 will be returned. Otherwise, if LOCALE is a locale type (one of
|
|
|
67 the symbols 'buffer, 'window, 'frame, 'device, 'device-class, or
|
|
|
68 'device-type), the specifications for all locales of that type will
|
|
|
69 be returned. Finally, if LOCALE is 'all, the specifications for all
|
|
|
70 locales of all types will be returned.
|
|
|
71
|
|
|
72 The specifications in a specifier determine what the value of
|
|
|
73 PROPERTY will be in a particular \"domain\" or set of circumstances,
|
|
|
74 which is typically a particular Emacs window along with the buffer
|
|
|
75 it contains and the frame and device it lies within. The value
|
|
|
76 is derived from the instantiator associated with the most specific
|
|
|
77 locale (in the order buffer, window, frame, device, and 'global)
|
|
|
78 that matches the domain in question. In other words, given a domain
|
|
|
79 (i.e. an Emacs window, usually), the specifier for PROPERTY will first
|
|
|
80 be searched for a specification whose locale is the buffer contained
|
|
|
81 within that window; then for a specification whose locale is the window
|
|
|
82 itself; then for a specification whose locale is the frame that the
|
|
|
83 window is contained within; etc. The first instantiator that is
|
|
|
84 valid for the domain (usually this means that the instantiator is
|
|
|
85 recognized by the device [i.e. the X server or TTY device] that the
|
|
|
86 domain is on. The function `glyph-property-instance' actually does
|
|
|
87 all this, and is used to determine how to display the glyph.

120 Under most circumstances, DOMAIN will be a particular window,

121 and the returned instance describes how the specified property

122 actually is displayed for that window and the particular buffer

123 in it. Note that this may not be the same as how the property

|

124 appears when the buffer is displayed in a different window or
|
|

125 frame, or how the property appears in the same window if you
|
|

126 switch to another buffer in that window; and in those cases,
|
|
|
127 the returned instance would be different.
|
|
|
128
|
|
|
129 DOMAIN defaults to the selected window if omitted.
|
|
|
130
|
|
|
131 DOMAIN can be a frame or device, instead of a window. The value
|
|
|
132 returned for a such a domain is used in special circumstances
|
|
|
133 when a more specific domain does not apply; for example, a frame
|
|
|
134 value might be used for coloring a toolbar, which is conceptually
|
|
|
135 attached to a frame rather than a particular window. The value
|
|
|
136 is also useful in determining what the value would be for a
|

|
137 particular window within the frame or device, if it is not

158 for the property.
|
|
|
159
|
|
|
160 For built-in properties, the actual value of the property is a
|
|
|
161 specifier and you cannot change this; but you can change the
|
|
|
162 specifications within the specifier, and that is what this function
|
|
|
163 will do. For user-defined properties, you can use this function
|
|
|
164 to either change the actual value of the property or, if this value
|
|
|
165 is a specifier, change the specifications within it.
|
|
|
166
|
|
|
167 If PROPERTY is a built-in property, the specifications to be added to
|
|
|
168 this property can be supplied in many different ways:
|
|
|
169
|
|
|
170 -- If VALUE is a simple instantiator (e.g. a string naming a font or
|
|
|
171 color) or a list of instantiators, then the instantiator(s) will
|
|
|
172 be added as a specification of the property for the given LOCALE
|
|
|
173 (which defaults to 'global if omitted).
|
|
|
174 -- If VALUE is a list of specifications (each of which is a cons of
|
|
|
175 a locale and a list of instantiators), then LOCALE must be nil
|
|
|
176 (it does not make sense to explicitly specify a locale in this
|
|
|
177 case), and specifications will be added as given.
|
|
|
178 -- If VALUE is a specifier (as would be returned by `glyph-property'
|
|
|
179 if no LOCALE argument is given), then some or all of the
|
|
|
180 specifications in the specifier will be added to the property.
|
|
|
181 In this case, the function is really equivalent to
|
|
|
182 `copy-specifier' and LOCALE has the same semantics (if it is
|
|
|
183 a particular locale, the specification for the locale will be
|
|
|
184 copied; if a locale type, specifications for all locales of
|
|
|
185 that type will be copied; if nil or 'all, then all
|
|
|
186 specifications will be copied).
|
|
|
187
|
|
|
188 HOW-TO-ADD should be either nil or one of the symbols 'prepend,
|
|
|
189 'append, 'remove-tag-set-prepend, 'remove-tag-set-append, 'remove-locale,
|
|
|
190 'remove-locale-type, or 'remove-all. See `copy-specifier' and
|
|
|
191 `add-spec-to-specifier' for a description of what each of
|
|
|
192 these means. Most of the time, you do not need to worry about
|
|
|
193 this argument; the default behavior usually is fine.
|
|
|
194
|
|
|
195 In general, it is OK to pass an instance object (e.g. as returned
|
|
|
196 by `glyph-property-instance') as an instantiator in place of
|
|
|
197 an actual instantiator. In such a case, the instantiator used
|
|
|
198 to create that instance object will be used (for example, if
|
|
|
199 you set a font-instance object as the value of the 'font
|
|
|
200 property, then the font name used to create that object will
|
|
|
201 be used instead). If some cases, however, doing this
|
|
|
202 conversion does not make sense, and this will be noted in
|
|
|
203 the documentation for particular types of instance objects.
|
|
|
204
|
|
|
205 If PROPERTY is not a built-in property, then this function will
|
|
|
206 simply set its value if LOCALE is nil. However, if LOCALE is
|
|
|
207 given, then this function will attempt to add VALUE as the
|
|
|
208 instantiator for the given LOCALE, using `add-spec-to-specifier'.
|
|
|
209 If the value of the property is not a specifier, it will
|
|
|
210 automatically be converted into a 'generic specifier.
