|
|
|
1211 Nothing is displayed.
|
|
|
1212 'text
|
|
|
1213 Displayed as text. The foreground and background colors and the
|
|
|
1214 font of the text are specified independent of the pixmap. Typically
|
|
|
1215 these attributes will come from the face of the surrounding text,
|
|
|
1216 unless a face is specified for the glyph in which the image appears.
|
|
|

|
|
|

|
|
|
1219 foreground and background can be specified independent of the pixmap;
|
|
|
1220 typically the pixmap assumes the foreground and background colors of
|
|
|
1221 the text around it, unless a face is specified for the glyph in which
|
|
|
1222 the image appears).
|
|
|
1223 'color-pixmap
|
|
|
1224 Displayed as a color pixmap.
|
|
|
1225 'pointer
|
|
|
1226 Used as the mouse pointer for a window.
|
|
|
1227 'subwindow
|
|
|
1228 A child window that is treated as an image. This allows (e.g.)
|
|
|
1229 another program to be responsible for drawing into the window.
|
|
398
|
1230 'widget

1232 button.

185

1235 are possible for a given instantiator, the "most natural" type

1236 for the instantiator's format is chosen. (For XBM, the most natural
|
|
|
1237 types are `mono-pixmap', followed by `color-pixmap', followed by
|
|
|
1238 `pointer'. For the other normal image formats, the most natural
|
|
|
1239 types are `color-pixmap', followed by `mono-pixmap', followed by
|
|
|
1240 `pointer'. For the string and formatted-string formats, the most
|
|
|
1241 natural types are `text', followed by `mono-pixmap' (not currently
|
|
|
1242 implemented), followed by `color-pixmap' (not currently implemented).
|
|
|
1243 The other formats can only be instantiated as one type. (If you
|
|
|
1244 want to control more specifically the order of the types into which
|
|
|
1245 an image is instantiated, just call `make-image-instance' repeatedly
|

3074
|
|
|
3075 An image specifier is used for images (pixmaps and the like). It is used
|
|
|
3076 to describe the actual image in a glyph. It is instanced as an image-
|
|
|
3077 instance.
|
|
|
3078
|
|
|
3079 Image instantiators come in many formats: `xbm', `xpm', `gif', `jpeg',
|
|
|
3080 etc. This describes the format of the data describing the image. The
|
|
|
3081 resulting image instances also come in many types -- `mono-pixmap',
|
|
|
3082 `color-pixmap', `text', `pointer', etc. This refers to the behavior of
|
|
|
3083 the image and the sorts of places it can appear. (For example, a
|
|
|
3084 color-pixmap image has fixed colors specified for it, while a
|
|
185
|
3085 mono-pixmap image comes in two unspecified shades "foreground" and
|
|
|
3086 "background" that are determined from the face of the glyph or
|
|
0
|
3087 surrounding text; a text image appears as a string of text and has an
|
|
|
3088 unspecified foreground, background, and font; a pointer image behaves
|
|
|
3089 like a mono-pixmap image but can only be used as a mouse pointer
|
|
|
3090 \[mono-pixmap images cannot be used as mouse pointers]; etc.) It is
|
|
|
3091 important to keep the distinction between image instantiator format and
|
|
|
3092 image instance type in mind. Typically, a given image instantiator
|
|
|
3093 format can result in many different image instance types (for example,
|
|
|
3094 `xpm' can be instanced as `color-pixmap', `mono-pixmap', or `pointer';
|
|
|
3095 whereas `cursor-font' can be instanced only as `pointer'), and a
|
|
|
3096 particular image instance type can be generated by many different
|
|
|
3097 image instantiator formats (e.g. `color-pixmap' can be generated by `xpm',
|
|
|
3098 `gif', `jpeg', etc.).

|
|
|
3101 instance types.

3103 An image instantiator should be a string or a vector of the form

|
|

3175 sort of pixmap or pointer will be created. [This includes picking up

3176 any specified hotspot or associated mask file.] Otherwise, if `pointer'

3177 is one of the allowable image-instance types and the string names a

3178 valid cursor-font name, the image will be created as a pointer.

|
|
|
3182 Inherit from the background-pixmap property of a face.

3183

|
3184 The valid keywords are:
|
|
|
3185
|
|
|
3186 :data
|
|
|
3187 (Inline data. For most formats above, this should be a string. For
|
|
|
3188 XBM images, this should be a list of three elements: width, height, and
|
|
|
3189 a string of bit data. This keyword is not valid for instantiator
|
|
|
3190 formats `nothing' and `inherit'.)
|
|
|
3191 :file
|
|
|
3192 (Data is contained in a file. The value is the name of this file.
|
|
|
3193 If both :data and :file are specified, the image is created from
|
|
|
3194 what is specified in :data and the string in :file becomes the
|
|
|
3195 value of the `image-instance-file-name' function when applied to
|
|
|
3196 the resulting image-instance. This keyword is not valid for
|
|
|
3197 instantiator formats `nothing', `string', `formatted-string',
|
|
122
|
3198 `cursor-font', `font', `autodetect', and `inherit'.)
|
|
0
|
3199 :foreground
|
|
|
3200 :background
|
|
384
|
3201 (For `xbm', `xface', `cursor-font', `widget' and `font'. These keywords
|
|
0
|
3202 allow you to explicitly specify foreground and background colors.
|
|
|
3203 The argument should be anything acceptable to `make-color-instance'.
|
|
|
3204 This will cause what would be a `mono-pixmap' to instead be colorized
|
|
|
3205 as a two-color color-pixmap, and specifies the foreground and/or
|
|
|
3206 background colors for a pointer instead of black and white.)
|
|
|
3207 :mask-data
|
|
|
3208 (For `xbm' and `xface'. This specifies a mask to be used with the
|
|
|
3209 bitmap. The format is a list of width, height, and bits, like for
|
|
|
3210 :data.)
|
|
|
3211 :mask-file
|
|
|
3212 (For `xbm' and `xface'. This specifies a file containing the mask data.
|
|
|
3213 If neither a mask file nor inline mask data is given for an XBM image,
|
|
|
3214 and the XBM image comes from a file, XEmacs will look for a mask file
|
|
185
|
3215 with the same name as the image file but with "Mask" or "msk"
|
|
|
3216 appended. For example, if you specify the XBM file "left_ptr"
|
|
|
3217 [usually located in "/usr/include/X11/bitmaps"], the associated
|
|
|
3218 mask file "left_ptrmsk" will automatically be picked up.)
|
|
0
|
3219 :hotspot-x
|
|
|
3220 :hotspot-y
|
|
|
3221 (For `xbm' and `xface'. These keywords specify a hotspot if the image
|
|
|
3222 is instantiated as a `pointer'. Note that if the XBM image file
|
|
|
3223 specifies a hotspot, it will automatically be picked up if no
|
|
|
3224 explicit hotspot is given.)
|
|
|
3225 :color-symbols
|
|
|
3226 (Only for `xpm'. This specifies an alist that maps strings
|
|
|
3227 that specify symbolic color names to the actual color to be used
|
|
|
3228 for that symbolic color (in the form of a string or a color-specifier
|
|
|
3229 object). If this is not specified, the contents of `xpm-color-symbols'
|
|
|
3230 are used to generate the alist.)
|
|
|
3231 :face
|
|
398
|
3232 (Only for `inherit'. This specifies the face to inherit from.
|
|
|
3233 For widget glyphs this also specifies the face to use for
|
|
|
3234 display. It defaults to gui-element-face.)
|
|
|
3235
|
|
|
3236 Keywords accepted as menu item specs are also accepted by widget
|
|
|
3237 glyphs. These are `:selected', `:active', `:suffix', `:keys',
|
|
|
3238 `:style', `:filter', `:config', `:included', `:key-sequence',
|
|
|
3239 `:accelerator', `:label' and `:callback'.
|
|
0
|
3240
|
|
|
3241 If instead of a vector, the instantiator is a string, it will be
|
|
|
3242 converted into a vector by looking it up according to the specs in the
|
|
|
3243 `console-type-image-conversion-list' (q.v.) for the console type of
|
|
|
3244 the domain (usually a window; sometimes a frame or device) over which
|
|
|
3245 the image is being instantiated.
|
|
|
3246
|
|
|
3247 If the instantiator specifies data from a file, the data will be read
|
|
|
3248 in at the time that the instantiator is added to the image (which may
|
|
|
3249 be well before when the image is actually displayed), and the
|
|
|
3250 instantiator will be converted into one of the inline-data forms, with
|
|
|
3251 the filename retained using a :file keyword. This implies that the
|
|
|
3252 file must exist when the instantiator is added to the image, but does
|
|
|
3253 not need to exist at any other time (e.g. it may safely be a temporary
|
|
|
3254 file).

4011 /* Subwindows are curious in that you have to physically unmap them to
|
|
384
|
4012 not display them. It is problematic deciding what to do in
|
|
|
4013 redisplay. We have two caches - a per-window instance cache that
|
|
|
4014 keeps track of subwindows on a window, these are linked to their
|
|
|
4015 instantiator in the hashtable and when the instantiator goes away
|
|
|
4016 we want the instance to go away also. However we also have a
|
|
|
4017 per-frame instance cache that we use to determine if a subwindow is
|
|
|
4018 obscuring an area that we want to clear. We need to be able to flip
|
|
|
4019 through this quickly so a hashtable is not suitable hence the
|
|
|
4020 subwindow_cachels. The question is should we just not mark
|
|
398
|
4021 instances in the subwindow_cachels or should we try and invalidate
|
|
384
|
4022 the cache at suitable points in redisplay? If we don't invalidate
|
|
|
4023 the cache it will fill up with crud that will only get removed when
|
|
|
4024 the frame is deleted. So invalidation is good, the question is when
|
|
|
4025 and whether we mark as well. Go for the simple option - don't mark,
|
|

4026 MARK_SUBWINDOWS_CHANGED when a subwindow gets deleted. */
