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

124 Under most circumstances, DOMAIN will be a particular window,
|
|
125 and the returned instance describes how the specified property
|
|
126 actually is displayed for that window and the particular buffer
|
|
127 in it. Note that this may not be the same as how the property
|
|
128 appears when the buffer is displayed in a different window or
|
|
129 frame, or how the property appears in the same window if you
|
|
130 switch to another buffer in that window; and in those cases,

131 the returned instance would be different.
|

132
|

133 DOMAIN defaults to the selected window if omitted.
|
|
134
|

135 DOMAIN can be a frame or device, instead of a window. The value
|
|
136 returned for a such a domain is used in special circumstances
|
|
137 when a more specific domain does not apply; for example, a frame
|
|
138 value might be used for coloring a toolbar, which is conceptually
|
|
139 attached to a frame rather than a particular window. The value
|
|
140 is also useful in determining what the value would be for a
|
|
141 particular window within the frame or device, if it is not
|
|
142 overridden by a more specific specification.

160 NOTE: If you want to remove a property from a glyph, use

161 `remove-glyph-property' rather than attempting to set a value of nil
|
|
162 for the property.
|
|
163
|
|
164 For built-in properties, the actual value of the property is a
|
|
165 specifier and you cannot change this; but you can change the
|
|
166 specifications within the specifier, and that is what this function
|
|
167 will do. For user-defined properties, you can use this function
|
|
168 to either change the actual value of the property or, if this value
|
|
169 is a specifier, change the specifications within it.
|
|
170
|
|
171 If PROPERTY is a built-in property, the specifications to be added to
|
|
172 this property can be supplied in many different ways:
|
|
173
|
|
174 -- If VALUE is a simple instantiator (e.g. a string naming a font or
|
|
175 color) or a list of instantiators, then the instantiator(s) will
|
|
176 be added as a specification of the property for the given LOCALE
|
|
177 (which defaults to 'global if omitted).
|
|
178 -- If VALUE is a list of specifications (each of which is a cons of
|
|
179 a locale and a list of instantiators), then LOCALE must be nil
|
|
180 (it does not make sense to explicitly specify a locale in this
|
|
181 case), and specifications will be added as given.
|
|
182 -- If VALUE is a specifier (as would be returned by `glyph-property'
|
|
183 if no LOCALE argument is given), then some or all of the
|
|
184 specifications in the specifier will be added to the property.
|
|
185 In this case, the function is really equivalent to
|
|
186 `copy-specifier' and LOCALE has the same semantics (if it is
|
|
187 a particular locale, the specification for the locale will be
|
|
188 copied; if a locale type, specifications for all locales of
|
|
189 that type will be copied; if nil or 'all, then all
|
|
190 specifications will be copied).
|
|
191
|
|
192 HOW-TO-ADD should be either nil or one of the symbols 'prepend,
|
|
193 'append, 'remove-tag-set-prepend, 'remove-tag-set-append, 'remove-locale,
|
|
194 'remove-locale-type, or 'remove-all. See `copy-specifier' and
|
|
195 `add-spec-to-specifier' for a description of what each of
|
|
196 these means. Most of the time, you do not need to worry about
|
|
197 this argument; the default behavior usually is fine.
|
|
198
|
|
199 In general, it is OK to pass an instance object (e.g. as returned
|
|
200 by `glyph-property-instance') as an instantiator in place of
|
|
201 an actual instantiator. In such a case, the instantiator used
|
|
202 to create that instance object will be used (for example, if
|
|
203 you set a font-instance object as the value of the 'font
|
|
204 property, then the font name used to create that object will
|
|
205 be used instead). If some cases, however, doing this
|
|
206 conversion does not make sense, and this will be noted in
|
|
207 the documentation for particular types of instance objects.
|
|
208
|
|
209 If PROPERTY is not a built-in property, then this function will
|
|
210 simply set its value if LOCALE is nil. However, if LOCALE is
|
|
211 given, then this function will attempt to add VALUE as the
|
|
212 instantiator for the given LOCALE, using `add-spec-to-specifier'.
|
|
213 If the value of the property is not a specifier, it will
|
|
214 automatically be converted into a 'generic specifier.
|
|
215
|
|
216
|
|
217 The following symbols have predefined meanings:
|
|
218
|
|
219 image The image used to display the glyph.
