1166 Image-instance objects encapsulate the way a particular image (pixmap,

1168 do not need to directly create image instances; use a glyph instead.

1169 However, it may occasionally be useful to explicitly create image

1170 instances, if you want more control over the instantiation process.

|

1172 DATA is an image instantiator, which describes the image; see

1173 `image-specifier-p' for a description of the allowed values.

1177
|
|
|
1178 'nothing
|
|
|
1179 Nothing is displayed.
|
|
|
1180 'text
|
|
|
1181 Displayed as text. The foreground and background colors and the
|
|
|
1182 font of the text are specified independent of the pixmap. Typically
|
|
|
1183 these attributes will come from the face of the surrounding text,
|
|
|
1184 unless a face is specified for the glyph in which the image appears.
|
|
|
1185 'mono-pixmap
|
|
|
1186 Displayed as a mono pixmap (a pixmap with only two colors where the
|
|
|
1187 foreground and background can be specified independent of the pixmap;
|
|
|
1188 typically the pixmap assumes the foreground and background colors of
|
|
|
1189 the text around it, unless a face is specified for the glyph in which
|
|
|
1190 the image appears).
|
|
|
1191 'color-pixmap
|
|
|
1192 Displayed as a color pixmap.
|
|
|
1193 'pointer
|
|
|
1194 Used as the mouse pointer for a window.
|
|
|
1195 'subwindow
|
|
|
1196 A child window that is treated as an image. This allows (e.g.)
|
|
|
1197 another program to be responsible for drawing into the window.
|
|
|
1198 'widget
|
|
|
1199 A child window that contains a window-system widget, e.g. a push
|
|
|
1200 button.

1202 The DEST-TYPES list is unordered. If multiple destination types
|
|
|
1203 are possible for a given instantiator, the "most natural" type
|
|
|
1204 for the instantiator's format is chosen. (For XBM, the most natural
|
|
|
1205 types are `mono-pixmap', followed by `color-pixmap', followed by
|
|
|
1206 `pointer'. For the other normal image formats, the most natural
|
|
|
1207 types are `color-pixmap', followed by `mono-pixmap', followed by
|
|
|
1208 `pointer'. For the string and formatted-string formats, the most
|
|
|
1209 natural types are `text', followed by `mono-pixmap' (not currently
|
|
|
1210 implemented), followed by `color-pixmap' (not currently implemented).
|
|
|
1211 The other formats can only be instantiated as one type. (If you
|
|
|
1212 want to control more specifically the order of the types into which
|
|
|
1213 an image is instantiated, just call `make-image-instance' repeatedly
|
|
|
1214 until it succeeds, passing less and less preferred destination types
|
|
|
1215 each time.
|
|
|
1216
|
|
|
1217 If DEST-TYPES is omitted, all possible types are allowed.
|
|
|
1218
|

1219 NO-ERROR controls what happens when the image cannot be generated.

1221 generated and this function returns nil. If anything else, a warning

3024
|
|
|
3025 An image specifier is used for images (pixmaps and the like). It is used
|
|
|
3026 to describe the actual image in a glyph. It is instanced as an image-
|
|
|
3027 instance.
|
|
|
3028
|
|
|
3029 Image instantiators come in many formats: `xbm', `xpm', `gif', `jpeg',
|
|
|
3030 etc. This describes the format of the data describing the image. The
|
|
|
3031 resulting image instances also come in many types -- `mono-pixmap',
|
|
|
3032 `color-pixmap', `text', `pointer', etc. This refers to the behavior of
|
|
|
3033 the image and the sorts of places it can appear. (For example, a
|
|
|
3034 color-pixmap image has fixed colors specified for it, while a
|
|
|
3035 mono-pixmap image comes in two unspecified shades "foreground" and
|
|
|
3036 "background" that are determined from the face of the glyph or
|
|
|
3037 surrounding text; a text image appears as a string of text and has an
|
|
|
3038 unspecified foreground, background, and font; a pointer image behaves
|
|
|
3039 like a mono-pixmap image but can only be used as a mouse pointer
|
|
|
3040 \[mono-pixmap images cannot be used as mouse pointers]; etc.) It is
|
|
|
3041 important to keep the distinction between image instantiator format and
|
|
|
3042 image instance type in mind. Typically, a given image instantiator
|
|
|
3043 format can result in many different image instance types (for example,
|
|
|
3044 `xpm' can be instanced as `color-pixmap', `mono-pixmap', or `pointer';
|
|
|
3045 whereas `cursor-font' can be instanced only as `pointer'), and a
|
|
|
3046 particular image instance type can be generated by many different
|
|
|
3047 image instantiator formats (e.g. `color-pixmap' can be generated by `xpm',
|
|
|
3048 `gif', `jpeg', etc.).

|
3098 On other window systems, the valid names will be specific to the
|
|
|
3099 type of window system. Can only be instanced as `pointer'.)
|
|
|
3100 'font
|
|
|
3101 (A glyph from a font; i.e. the name of a font, and glyph index into it
|
|
|
3102 of the form "FONT fontname index [[mask-font] mask-index]".
|
|
|
3103 Currently can only be instanced as `pointer', although this should
|
|
|
3104 probably be fixed.)
|
|
|
3105 'subwindow
|
|
|
3106 (An embedded windowing system window.)
|
|
|
3107 'edit-field
|
|
|
3108 (A text editing widget glyph.)
|
|
|
3109 'button
|
|
|
3110 (A button widget glyph; either a push button, radio button or toggle button.)
|
|
|
3111 'tab-control
|
|
|
3112 (A tab widget glyph; a series of user selectable tabs.)
|
|
|
3113 'progress-gauge
|
|
|
3114 (A sliding widget glyph, for showing progress.)
|
|
|
3115 'combo-box
|
|
|
3116 (A drop list of selectable items in a widget glyph, for editing text.)
|
|
|
3117 'label
|
|
|
3118 (A static, text-only, widget glyph; for displaying text.)
|
|
|
3119 'tree-view
|
|
|
3120 (A folding widget glyph.)
|
|
|
3121 'autodetect
|
|
|
3122 (XEmacs tries to guess what format the data is in. If X support
|
|
|
3123 exists, the data string will be checked to see if it names a filename.
|
|
|
3124 If so, and this filename contains XBM or XPM data, the appropriate
|
|
|
3125 sort of pixmap or pointer will be created. [This includes picking up
|
|
|
3126 any specified hotspot or associated mask file.] Otherwise, if `pointer'
|
|
|
3127 is one of the allowable image-instance types and the string names a
|
|
|
3128 valid cursor-font name, the image will be created as a pointer.
|
|
|
3129 Otherwise, the image will be displayed as text. If no X support
|
|
|
3130 exists, the image will always be displayed as text.)
|
|
|
3131 'inherit
|
|
|
3132 Inherit from the background-pixmap property of a face.
|
|
|
3133
|
|
|
3134 The valid keywords are:
|
|
|
3135
|
|
|
3136 :data
|
|
|
3137 (Inline data. For most formats above, this should be a string. For
|
|
|
3138 XBM images, this should be a list of three elements: width, height, and
|
|
|
3139 a string of bit data. This keyword is not valid for instantiator
|
|
|
3140 formats `nothing' and `inherit'.)
|
|
|
3141 :file
|
|
|
3142 (Data is contained in a file. The value is the name of this file.
|
|
|
3143 If both :data and :file are specified, the image is created from
|
|
|
3144 what is specified in :data and the string in :file becomes the
|
|
|
3145 value of the `image-instance-file-name' function when applied to
|
|
|
3146 the resulting image-instance. This keyword is not valid for
|
|
|
3147 instantiator formats `nothing', `string', `formatted-string',
|
|
|
3148 `cursor-font', `font', `autodetect', and `inherit'.)
|
|
|
3149 :foreground
|
|
|
3150 :background
|
|
|
3151 (For `xbm', `xface', `cursor-font', `widget' and `font'. These keywords
|
|
|
3152 allow you to explicitly specify foreground and background colors.
|
|
|
3153 The argument should be anything acceptable to `make-color-instance'.
|
|
|
3154 This will cause what would be a `mono-pixmap' to instead be colorized
|
|
|
3155 as a two-color color-pixmap, and specifies the foreground and/or
|
|
|
3156 background colors for a pointer instead of black and white.)
|
|
|
3157 :mask-data
|
|
|
3158 (For `xbm' and `xface'. This specifies a mask to be used with the
|
|
|
3159 bitmap. The format is a list of width, height, and bits, like for
|
|
|
3160 :data.)
|
|
|
3161 :mask-file
|
|
|
3162 (For `xbm' and `xface'. This specifies a file containing the mask data.
|
|
|
3163 If neither a mask file nor inline mask data is given for an XBM image,
|
|
|
3164 and the XBM image comes from a file, XEmacs will look for a mask file
|
|
|
3165 with the same name as the image file but with "Mask" or "msk"
|
|
|
3166 appended. For example, if you specify the XBM file "left_ptr"
|
|
|
3167 [usually located in "/usr/include/X11/bitmaps"], the associated
|
|
|
3168 mask file "left_ptrmsk" will automatically be picked up.)
|
|
|
3169 :hotspot-x
|
|
|
3170 :hotspot-y
|
|
|
3171 (For `xbm' and `xface'. These keywords specify a hotspot if the image
|
|
|
3172 is instantiated as a `pointer'. Note that if the XBM image file
|
|
|
3173 specifies a hotspot, it will automatically be picked up if no
|
|
|
3174 explicit hotspot is given.)
|
|
|
3175 :color-symbols
|
|
|
3176 (Only for `xpm'. This specifies an alist that maps strings
|
|
|
3177 that specify symbolic color names to the actual color to be used
|
|
|
3178 for that symbolic color (in the form of a string or a color-specifier
|
|
|
3179 object). If this is not specified, the contents of `xpm-color-symbols'
|
|
|
3180 are used to generate the alist.)
|
|
|
3181 :face
|
|
|
3182 (Only for `inherit'. This specifies the face to inherit from.
|
|
|
3183 For widget glyphs this also specifies the face to use for
|
|
|
3184 display. It defaults to gui-element-face.)
|
|
|
3185
|
|
|
3186 Keywords accepted as menu item specs are also accepted by widget
|
|
|
3187 glyphs. These are `:selected', `:active', `:suffix', `:keys',
|
|
|
3188 `:style', `:filter', `:config', `:included', `:key-sequence',
|
|
|
3189 `:accelerator', `:label' and `:callback'.
|
|
|
3190
|
|
|
3191 If instead of a vector, the instantiator is a string, it will be
|
|
|
3192 converted into a vector by looking it up according to the specs in the
|
|
|
3193 `console-type-image-conversion-list' (q.v.) for the console type of
|
|
|
3194 the domain (usually a window; sometimes a frame or device) over which
|
|
|
3195 the image is being instantiated.
|
|
|
3196
|
|
|
3197 If the instantiator specifies data from a file, the data will be read
|
|
|
3198 in at the time that the instantiator is added to the image (which may
|
|
|
3199 be well before when the image is actually displayed), and the
|
|
|
3200 instantiator will be converted into one of the inline-data forms, with
|
|
|
3201 the filename retained using a :file keyword. This implies that the
|
|
|
3202 file must exist when the instantiator is added to the image, but does
|
|
|
3203 not need to exist at any other time (e.g. it may safely be a temporary
|
|
|
3204 file).

3941 redisplay. We have two caches - a per-window instance cache that

3942 keeps track of subwindows on a window, these are linked to their

3943 instantiator in the hashtable and when the instantiator goes away

3944 we want the instance to go away also. However we also have a

3946 obscuring an area that we want to clear. We need to be able to flip

3947 through this quickly so a hashtable is not suitable hence the

3948 subwindow_cachels. The question is should we just not mark

3949 instances in the subwindow_cachels or should we try and invalidate

3950 the cache at suitable points in redisplay? If we don't invalidate
|

|
3951 the cache it will fill up with crud that will only get removed when

3952 the frame is deleted. So invalidation is good, the question is when

3953 and whether we mark as well. Go for the simple option - don't mark,
