|
|
|
93
|
|
|
94 If LOCALE is omitted, the FACE's actual value for PROPERTY will be
|
|
|
95 returned. For built-in properties, this will be a specifier object
|
|
|
96 of a type appropriate to the property (e.g. a font or color
|
|
|
97 specifier). For other properties, this could be anything.
|
|
|
98
|
|
|
99 If LOCALE is supplied, then instead of returning the actual value,
|
|
|
100 the specification(s) for the given locale or locale type will
|
|
|
101 be returned. This will only work if the actual value of
|
|
|
102 PROPERTY is a specifier (this will always be the case for built-in
|
|
|
103 properties, but not or not may apply to user-defined properties).
|
|
|
104 If the actual value of PROPERTY is not a specifier, this value
|
|
|
105 will simply be returned regardless of LOCALE.
|
|
|
106
|
|
|
107 The return value will be a list of instantiators (e.g. strings
|
|
|
108 specifying a font or color name), or a list of specifications, each
|
|
|
109 of which is a cons of a locale and a list of instantiators.
|
|
|
110 Specifically, if LOCALE is a particular locale (a buffer, window,
|
|
|
111 frame, device, or 'global), a list of instantiators for that locale
|
|
|
112 will be returned. Otherwise, if LOCALE is a locale type (one of
|
|
|
113 the symbols 'buffer, 'window, 'frame, or 'device), the specifications
|
|
|
114 for all locales of that type will be returned. Finally, if LOCALE is
|
|
|
115 'all, the specifications for all locales of all types will be returned.
|
|
|
116
|
|
|
117 The specifications in a specifier determine what the value of
|
|
|
118 PROPERTY will be in a particular \"domain\" or set of circumstances,
|
|
|
119 which is typically a particular Emacs window along with the buffer
|
|
|
120 it contains and the frame and device it lies within. The value
|
|
|
121 is derived from the instantiator associated with the most specific
|
|
|
122 locale (in the order buffer, window, frame, device, and 'global)
|
|
|
123 that matches the domain in question. In other words, given a domain
|
|
|
124 (i.e. an Emacs window, usually), the specifier for PROPERTY will first
|
|
|
125 be searched for a specification whose locale is the buffer contained
|
|
|
126 within that window; then for a specification whose locale is the window
|
|
|
127 itself; then for a specification whose locale is the frame that the
|
|
|
128 window is contained within; etc. The first instantiator that is
|
|
|
129 valid for the domain (usually this means that the instantiator is
|
|
|
130 recognized by the device [i.e. the X server or TTY device] that the
|
|
|
131 domain is on. The function `face-property-instance' actually does
|
|
|
132 all this, and is used to determine how to display the face.

166 Under most circumstances, DOMAIN will be a particular window,
|
|
|
167 and the returned instance describes how the specified property
|
|
|
168 actually is displayed for that window and the particular buffer
|
|
|
169 in it. Note that this may not be the same as how the property
|
|
|
170 appears when the buffer is displayed in a different window or
|
|
|
171 frame, or how the property appears in the same window if you
|
|
|
172 switch to another buffer in that window; and in those cases,
|
|
|
173 the returned instance would be different.
|
|
|
174
|
|
|
175 The returned instance will typically be a color-instance,
|
|
|
176 font-instance, or pixmap-instance object, and you can query
|
|
|
177 it using the appropriate object-specific functions. For example,
|
|
|
178 you could use `color-instance-rgb-components' to find out the
|
|
|
179 RGB (red, green, and blue) components of how the 'background
|
|
|
180 property of the 'highlight face is displayed in a particular
|
|
|
181 window. The results might be different from the results
|
|
|
182 you would get for another window (perhaps the user
|
|
|
183 specified a different color for the frame that window is on;
|
|
|
184 or perhaps the same color was specified but the window is
|
|
|
185 on a different X server, and that X server has different RGB
|
|
|
186 values for the color from this one).
|

|
|
188 DOMAIN defaults to the selected window if omitted.
|
|
|
189
|
|
|
190 DOMAIN can be a frame or device, instead of a window. The value
|
|
|
191 returned for a such a domain is used in special circumstances
|
|
|
192 when a more specific domain does not apply; for example, a frame
|
|
|
193 value might be used for coloring a toolbar, which is conceptually
|
|
|
194 attached to a frame rather than a particular window. The value
|
|
|
195 is also useful in determining what the value would be for a
|
|
|
196 particular window within the frame or device, if it is not
|
|
|
197 overridden by a more specific specification.

236 NOTE: If you want to remove a property from a face, use `remove-face-property'
|
|
|
237 rather than attempting to set a value of nil for the property.
|
|
|
238
|
|
|
239 For built-in properties, the actual value of the property is a
|
|
|
240 specifier and you cannot change this; but you can change the
|
|
|
241 specifications within the specifier, and that is what this function
|
|
|
242 will do. For user-defined properties, you can use this function
|
|
|
243 to either change the actual value of the property or, if this value
|
|
|
244 is a specifier, change the specifications within it.
|
|
|
245
|
|
|
246 If PROPERTY is a built-in property, the specifications to be added to
|
|
|
247 this property can be supplied in many different ways:
|
|
|
248
|
|
|
249 -- If VALUE is a simple instantiator (e.g. a string naming a font or
|
|
|
250 color) or a list of instantiators, then the instantiator(s) will
|
|
|
251 be added as a specification of the property for the given LOCALE
|
|
|
252 (which defaults to 'global if omitted).
|
|
|
253 -- If VALUE is a list of specifications (each of which is a cons of
|
|
|
254 a locale and a list of instantiators), then LOCALE must be nil
|
|
|
255 (it does not make sense to explicitly specify a locale in this
|
|
|
256 case), and specifications will be added as given.
|
|
|
257 -- If VALUE is a specifier (as would be returned by `face-property'
|
|
|
258 if no LOCALE argument is given), then some or all of the
|
|
|
259 specifications in the specifier will be added to the property.
|
|
|
260 In this case, the function is really equivalent to
|
|
|
261 `copy-specifier' and LOCALE has the same semantics (if it is
|
|
|
262 a particular locale, the specification for the locale will be
|
|
|
263 copied; if a locale type, specifications for all locales of
|
|
|
264 that type will be copied; if nil or 'all, then all
|
|
|
265 specifications will be copied).
|
|
|
266
|
|
|
267 HOW-TO-ADD should be either nil or one of the symbols 'prepend,
|
|
|
268 'append, 'remove-tag-set-prepend, 'remove-tag-set-append, 'remove-locale,
|
|
|
269 'remove-locale-type, or 'remove-all. See `copy-specifier' and
|
|
|
270 `add-spec-to-specifier' for a description of what each of
|
|
|
271 these means. Most of the time, you do not need to worry about
|
|
|
272 this argument; the default behavior usually is fine.
|
|
|
273
|
|
|
274 In general, it is OK to pass an instance object (e.g. as returned
|
|
|
275 by `face-property-instance') as an instantiator in place of
|
|
|
276 an actual instantiator. In such a case, the instantiator used
|
|
|
277 to create that instance object will be used (for example, if
|
|
|
278 you set a font-instance object as the value of the 'font
|
|
|
279 property, then the font name used to create that object will
|
|
|
280 be used instead). If some cases, however, doing this
|
|
|
281 conversion does not make sense, and this will be noted in
|
|
|
282 the documentation for particular types of instance objects.
|
|
|
283
|
|
|
284 If PROPERTY is not a built-in property, then this function will
|
|
|
285 simply set its value if LOCALE is nil. However, if LOCALE is
|
|
|
286 given, then this function will attempt to add VALUE as the
|
|
|
287 instantiator for the given LOCALE, using `add-spec-to-specifier'.
|
|
|
288 If the value of the property is not a specifier, it will
|
|
|
289 automatically be converted into a 'generic specifier.

948 what sort of locale is given. If you gave a device, frame, or window,
|
|
|
949 then it's always possible to determine what the font actually will be,
|
|
|
950 so this is determined and the resulting font is frobbed and added back as a
|
|
|
951 specification for this locale. If LOCALE is a buffer, however, you can't
|
|
|
952 determine what the font will actually be unless there's actually a
|
|
|
953 specification given for that particular buffer (otherwise, it depends
|
|
|
954 on what window and frame the buffer appears in, and might not even be
|
|
|
955 well-defined if the buffer appears multiple times in different places);
|
|
|
956 therefore you will get an error unless there's a specification for the
|
|
|
957 buffer.
|
|
|
958
|
|
|
959 Finally, in some cases (specifically, when LOCALE is not a locale type),
|
|
|
960 if the frobbing didn't actually make the font look any different
|
|
|
961 \(this happens, for example, if your font specification is already bold
|
|
|
962 or has no bold equivalent), and currently looks like the font of the
|
|
|
963 'default face, it is set to inherit from the 'bold face. This is kludgy
