|
|
|
1198 'nothing
|
|
|
1199 Nothing is displayed.
|
|
|
1200 'text
|
|
|
1201 Displayed as text. The foreground and background colors and the
|
|
|
1202 font of the text are specified independent of the pixmap. Typically
|
|
|
1203 these attributes will come from the face of the surrounding text,
|
|
|
1204 unless a face is specified for the glyph in which the image appears.
|
|
|
1205 'mono-pixmap
|
|
|
1206 Displayed as a mono pixmap (a pixmap with only two colors where the
|
|
|
1207 foreground and background can be specified independent of the pixmap;
|
|
|
1208 typically the pixmap assumes the foreground and background colors of
|
|
|
1209 the text around it, unless a face is specified for the glyph in which
|
|
|
1210 the image appears).
|
|
|
1211 'color-pixmap
|
|
|
1212 Displayed as a color pixmap.
|
|
|
1213 'pointer
|
|
|
1214 Used as the mouse pointer for a window.
|
|
|
1215 'subwindow
|
|
|
1216 A child window that is treated as an image. This allows (e.g.)
|
|
|
1217 another program to be responsible for drawing into the window.
|
|
398
|
1218 'widget
|
|
|
1219 A child window that contains a window-system widget, e.g. a push
|
|
|
1220 button.

|
|
185
|
1223 are possible for a given instantiator, the "most natural" type
|
|
0
|
1224 for the instantiator's format is chosen. (For XBM, the most natural
|
|
|
1225 types are `mono-pixmap', followed by `color-pixmap', followed by
|
|
|
1226 `pointer'. For the other normal image formats, the most natural
|
|
|
1227 types are `color-pixmap', followed by `mono-pixmap', followed by
|
|
|
1228 `pointer'. For the string and formatted-string formats, the most
|
|
|
1229 natural types are `text', followed by `mono-pixmap' (not currently
|
|
|
1230 implemented), followed by `color-pixmap' (not currently implemented).
|
|
|
1231 The other formats can only be instantiated as one type. (If you
|
|
|
1232 want to control more specifically the order of the types into which
|
|
|
1233 an image is instantiated, just call `make-image-instance' repeatedly
|

1234 until it succeeds, passing less and less preferred destination types

2753 in faces.

|

|
3056 An image specifier is used for images (pixmaps and the like). It is used
|
|
|
3057 to describe the actual image in a glyph. It is instanced as an image-
|
|
|
3058 instance.
|
|
|
3059
|
|
|
3060 Image instantiators come in many formats: `xbm', `xpm', `gif', `jpeg',
|
|
|
3061 etc. This describes the format of the data describing the image. The
|
|
|
3062 resulting image instances also come in many types -- `mono-pixmap',
|
|
|
3063 `color-pixmap', `text', `pointer', etc. This refers to the behavior of
|
|
|
3064 the image and the sorts of places it can appear. (For example, a
|
|
|
3065 color-pixmap image has fixed colors specified for it, while a
|
|
185
|
3066 mono-pixmap image comes in two unspecified shades "foreground" and
|
|
|
3067 "background" that are determined from the face of the glyph or
|
|
0
|
3068 surrounding text; a text image appears as a string of text and has an
|
|
|
3069 unspecified foreground, background, and font; a pointer image behaves
|
|
|
3070 like a mono-pixmap image but can only be used as a mouse pointer
|
|
|
3071 \[mono-pixmap images cannot be used as mouse pointers]; etc.) It is
|
|
|
3072 important to keep the distinction between image instantiator format and
|
|
|
3073 image instance type in mind. Typically, a given image instantiator
|
|
|
3074 format can result in many different image instance types (for example,
|
|
|
3075 `xpm' can be instanced as `color-pixmap', `mono-pixmap', or `pointer';
|
|
|
3076 whereas `cursor-font' can be instanced only as `pointer'), and a
|
|
|
3077 particular image instance type can be generated by many different
|
|
|
3078 image instantiator formats (e.g. `color-pixmap' can be generated by `xpm',
|
|
|
3079 `gif', `jpeg', etc.).
|
|
|
3080
|
|
|
3081 See `make-image-instance' for a more detailed discussion of image
|
|
|
3082 instance types.

|
|

3158 is one of the allowable image-instance types and the string names a

|
|
|
3163 Inherit from the background-pixmap property of a face.

3164

|
3165 The valid keywords are:
|
|
|
3166
|
|
|
3167 :data
|
|
|
3168 (Inline data. For most formats above, this should be a string. For
|
|
|
3169 XBM images, this should be a list of three elements: width, height, and
|
|
|
3170 a string of bit data. This keyword is not valid for instantiator
|
|
|
3171 formats `nothing' and `inherit'.)
|
|
|
3172 :file
|
|
|
3173 (Data is contained in a file. The value is the name of this file.
|
|
|
3174 If both :data and :file are specified, the image is created from
|
|
|
3175 what is specified in :data and the string in :file becomes the
|
|
|
3176 value of the `image-instance-file-name' function when applied to
|
|
|
3177 the resulting image-instance. This keyword is not valid for
|
|
|
3178 instantiator formats `nothing', `string', `formatted-string',
|
|
122
|
3179 `cursor-font', `font', `autodetect', and `inherit'.)
|
|
0
|
3180 :foreground
|
|
|
3181 :background
|
|
384
|
3182 (For `xbm', `xface', `cursor-font', `widget' and `font'. These keywords
|
|
0
|
3183 allow you to explicitly specify foreground and background colors.
|
|
|
3184 The argument should be anything acceptable to `make-color-instance'.
|
|
|
3185 This will cause what would be a `mono-pixmap' to instead be colorized
|
|
|
3186 as a two-color color-pixmap, and specifies the foreground and/or
|
|
|
3187 background colors for a pointer instead of black and white.)
|
|
|
3188 :mask-data
|
|
|
3189 (For `xbm' and `xface'. This specifies a mask to be used with the
|
|
|
3190 bitmap. The format is a list of width, height, and bits, like for
|
|
|
3191 :data.)
|
|
|
3192 :mask-file
|
|
|
3193 (For `xbm' and `xface'. This specifies a file containing the mask data.
|
|
|
3194 If neither a mask file nor inline mask data is given for an XBM image,
|
|
|
3195 and the XBM image comes from a file, XEmacs will look for a mask file
|
|
185
|
3196 with the same name as the image file but with "Mask" or "msk"
|
|
|
3197 appended. For example, if you specify the XBM file "left_ptr"
|
|
|
3198 [usually located in "/usr/include/X11/bitmaps"], the associated
|
|
|
3199 mask file "left_ptrmsk" will automatically be picked up.)
|
|
0
|
3200 :hotspot-x
|
|
|
3201 :hotspot-y
|
|
|
3202 (For `xbm' and `xface'. These keywords specify a hotspot if the image
|
|
|
3203 is instantiated as a `pointer'. Note that if the XBM image file
|
|
|
3204 specifies a hotspot, it will automatically be picked up if no
|
|
|
3205 explicit hotspot is given.)
|
|
|
3206 :color-symbols
|
|
|
3207 (Only for `xpm'. This specifies an alist that maps strings
|
|
|
3208 that specify symbolic color names to the actual color to be used
|
|
|
3209 for that symbolic color (in the form of a string or a color-specifier
|
|
|
3210 object). If this is not specified, the contents of `xpm-color-symbols'
|
|
|
3211 are used to generate the alist.)
|
|
|
3212 :face
|
|
398
|
3213 (Only for `inherit'. This specifies the face to inherit from.
|
|
|
3214 For widget glyphs this also specifies the face to use for
|
|
|
3215 display. It defaults to gui-element-face.)
|
|
|
3216
|
|
|
3217 Keywords accepted as menu item specs are also accepted by widget
|
|
|
3218 glyphs. These are `:selected', `:active', `:suffix', `:keys',
|
|
|
3219 `:style', `:filter', `:config', `:included', `:key-sequence',
|
|
|
3220 `:accelerator', `:label' and `:callback'.
|
|
0
|
3221
|
|
|
3222 If instead of a vector, the instantiator is a string, it will be
|
|
|
3223 converted into a vector by looking it up according to the specs in the
|
|
|
3224 `console-type-image-conversion-list' (q.v.) for the console type of
|
|
|
3225 the domain (usually a window; sometimes a frame or device) over which
|
|
|
3226 the image is being instantiated.
|
|
|
3227
|
|
|
3228 If the instantiator specifies data from a file, the data will be read
|
|
|
3229 in at the time that the instantiator is added to the image (which may
|
|
|
3230 be well before when the image is actually displayed), and the
|
|
|
3231 instantiator will be converted into one of the inline-data forms, with
|
|
|
3232 the filename retained using a :file keyword. This implies that the
|
|
|
3233 file must exist when the instantiator is added to the image, but does
|
|
|
3234 not need to exist at any other time (e.g. it may safely be a temporary
|
|
|
3235 file).

3994 redisplay. We have two caches - a per-window instance cache that

3995 keeps track of subwindows on a window, these are linked to their

3996 instantiator in the hashtable and when the instantiator goes away

3997 we want the instance to go away also. However we also have a

3999 obscuring an area that we want to clear. We need to be able to flip

|
4000 through this quickly so a hashtable is not suitable hence the
|
|
|
4001 subwindow_cachels. The question is should we just not mark

4002 instances in the subwindow_cachels or should we try and invalidate

4003 the cache at suitable points in redisplay? If we don't invalidate
|
|
|
4004 the cache it will fill up with crud that will only get removed when

4005 the frame is deleted. So invalidation is good, the question is when

4006 and whether we mark as well. Go for the simple option - don't mark,
