|

1217 another program to be responsible for drawing into the window.

1222 The DEST-TYPES list is unordered. If multiple destination types
|
|
1223 are possible for a given instantiator, the "most natural" type
|
|
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
|
|
1235 each time.
|
|
1236
|
|
1237 If DEST-TYPES is omitted, all possible types are allowed.
|
|
1238
|
|
1239 NO-ERROR controls what happens when the image cannot be generated.
|
|
1240 If nil, an error message is generated. If t, no messages are
|
|
1241 generated and this function returns nil. If anything else, a warning
|
|
1242 message is generated and this function returns nil.

2736
|
|
2737 An image specifier is used for images (pixmaps and the like). It is used
|
|
2738 to describe the actual image in a glyph. It is instanced as an image-
|
|
2739 instance.
|
|
2740
|
|
2741 Image instantiators come in many formats: `xbm', `xpm', `gif', `jpeg',
|
|
2742 etc. This describes the format of the data describing the image. The
|
|
2743 resulting image instances also come in many types -- `mono-pixmap',
|
|
2744 `color-pixmap', `text', `pointer', etc. This refers to the behavior of
|
|
2745 the image and the sorts of places it can appear. (For example, a
|
|
2746 color-pixmap image has fixed colors specified for it, while a
|
|
2747 mono-pixmap image comes in two unspecified shades "foreground" and
|
|
2748 "background" that are determined from the face of the glyph or
|
|
2749 surrounding text; a text image appears as a string of text and has an
|
|
2750 unspecified foreground, background, and font; a pointer image behaves
|
|
2751 like a mono-pixmap image but can only be used as a mouse pointer
|
|
2752 \[mono-pixmap images cannot be used as mouse pointers]; etc.) It is
|
|
2753 important to keep the distinction between image instantiator format and
|
|
2754 image instance type in mind. Typically, a given image instantiator
|
|
2755 format can result in many different image instance types (for example,
|
|
2756 `xpm' can be instanced as `color-pixmap', `mono-pixmap', or `pointer';
|
|
2757 whereas `cursor-font' can be instanced only as `pointer'), and a
|
|
2758 particular image instance type can be generated by many different
|
|
2759 image instantiator formats (e.g. `color-pixmap' can be generated by `xpm',
|
|
2760 `gif', `jpeg', etc.).
|
|
2761
|
|
2762 See `make-image-instance' for a more detailed discussion of image
|
|
2763 instance types.
|
|
2764
|
|
2765 An image instantiator should be a string or a vector of the form

|
2808 of the standard cursor names from appendix B of the Xlib manual
|
|
2809 [also known as the file <X11/cursorfont.h>] minus the XC_ prefix.
|
|
2810 On other window systems, the valid names will be specific to the
|
|
2811 type of window system. Can only be instanced as `pointer'.)
|
|
2812 'font
|
|
2813 (A glyph from a font; i.e. the name of a font, and glyph index into it
|
|
2814 of the form "FONT fontname index [[mask-font] mask-index]".
|
|
2815 Currently can only be instanced as `pointer', although this should
|
|
2816 probably be fixed.)
|
|
2817 'subwindow
|
|
2818 (An embedded windowing system window.)
|
|
2819 'edit-field
|
|
2820 (A text editing widget glyph.)
|
|
2821 'button
|
|
2822 (A button widget glyph; either a push button, radio button or toggle button.)
|
|
2823 'tab-control
|
|
2824 (A tab widget glyph; a series of user selectable tabs.)
|
|
2825 'progress-gauge
|
|
2826 (A sliding widget glyph, for showing progress.)
|
|
2827 'combo-box
|
|
2828 (A drop list of selectable items in a widget glyph, for editing text.)
|
|
2829 'label
|
|
2830 (A static, text-only, widget glyph; for displaying text.)
|
|
2831 'tree-view
|
|
2832 (A folding widget glyph.)
|
|
2833 'autodetect
|
|
2834 (XEmacs tries to guess what format the data is in. If X support
|
|
2835 exists, the data string will be checked to see if it names a filename.
|
|
2836 If so, and this filename contains XBM or XPM data, the appropriate
|
|
2837 sort of pixmap or pointer will be created. [This includes picking up
|
|
2838 any specified hotspot or associated mask file.] Otherwise, if `pointer'
|
|
2839 is one of the allowable image-instance types and the string names a
|
|
2840 valid cursor-font name, the image will be created as a pointer.
|
|
2841 Otherwise, the image will be displayed as text. If no X support
|
|
2842 exists, the image will always be displayed as text.)
|
|
2843 'inherit
|
|
2844 Inherit from the background-pixmap property of a face.
|
|
2845
|
|
2846 The valid keywords are:
|
|
2847
|
|
2848 :data
|
|
2849 (Inline data. For most formats above, this should be a string. For
|
|
2850 XBM images, this should be a list of three elements: width, height, and
|
|
2851 a string of bit data. This keyword is not valid for instantiator
|
|
2852 formats `nothing' and `inherit'.)
|
|
2853 :file
|
|
2854 (Data is contained in a file. The value is the name of this file.
|
|
2855 If both :data and :file are specified, the image is created from
|
|
2856 what is specified in :data and the string in :file becomes the
|
|
2857 value of the `image-instance-file-name' function when applied to
|
|
2858 the resulting image-instance. This keyword is not valid for
|
|
2859 instantiator formats `nothing', `string', `formatted-string',
|
|
2860 `cursor-font', `font', `autodetect', and `inherit'.)
|
|
2861 :foreground
|
|
2862 :background
|
|
2863 (For `xbm', `xface', `cursor-font', `widget' and `font'. These keywords
|
|
2864 allow you to explicitly specify foreground and background colors.
|
|
2865 The argument should be anything acceptable to `make-color-instance'.
|
|
2866 This will cause what would be a `mono-pixmap' to instead be colorized
|
|
2867 as a two-color color-pixmap, and specifies the foreground and/or
|
|
2868 background colors for a pointer instead of black and white.)
|
|
2869 :mask-data
|
|
2870 (For `xbm' and `xface'. This specifies a mask to be used with the
|
|
2871 bitmap. The format is a list of width, height, and bits, like for
|
|
2872 :data.)
|
|
2873 :mask-file
|
|
2874 (For `xbm' and `xface'. This specifies a file containing the mask data.
|
|
2875 If neither a mask file nor inline mask data is given for an XBM image,
|
|
2876 and the XBM image comes from a file, XEmacs will look for a mask file
|
|
2877 with the same name as the image file but with "Mask" or "msk"
|
|
2878 appended. For example, if you specify the XBM file "left_ptr"
|
|
2879 [usually located in "/usr/include/X11/bitmaps"], the associated
|
|
2880 mask file "left_ptrmsk" will automatically be picked up.)
|
|
2881 :hotspot-x
|
|
2882 :hotspot-y
|
|
2883 (For `xbm' and `xface'. These keywords specify a hotspot if the image
|
|
2884 is instantiated as a `pointer'. Note that if the XBM image file
|
|
2885 specifies a hotspot, it will automatically be picked up if no
|
|
2886 explicit hotspot is given.)
|
|
2887 :color-symbols
|
|
2888 (Only for `xpm'. This specifies an alist that maps strings
|
|
2889 that specify symbolic color names to the actual color to be used
|
|
2890 for that symbolic color (in the form of a string or a color-specifier
|
|
2891 object). If this is not specified, the contents of `xpm-color-symbols'
|
|
2892 are used to generate the alist.)
|
|
2893 :face
|
|
2894 (Only for `inherit'. This specifies the face to inherit from.
|
|
2895 For widget glyphs this also specifies the face to use for
|
|
2896 display. It defaults to gui-element-face.)
|
|
2897
|
|
2898 Keywords accepted as menu item specs are also accepted by widget
|
|
2899 glyphs. These are `:selected', `:active', `:suffix', `:keys',
|
|
2900 `:style', `:filter', `:config', `:included', `:key-sequence',
|
|
2901 `:accelerator', `:label' and `:callback'.
|
|
2902
|
|
2903 If instead of a vector, the instantiator is a string, it will be
|
|
2904 converted into a vector by looking it up according to the specs in the
|
|
2905 `console-type-image-conversion-list' (q.v.) for the console type of
|
|
2906 the domain (usually a window; sometimes a frame or device) over which
|
|
2907 the image is being instantiated.
|
|
2908
|
|
2909 If the instantiator specifies data from a file, the data will be read
|
|
2910 in at the time that the instantiator is added to the image (which may
|
|
2911 be well before when the image is actually displayed), and the
|
|
2912 instantiator will be converted into one of the inline-data forms, with
|
|
2913 the filename retained using a :file keyword. This implies that the
|
|
2914 file must exist when the instantiator is added to the image, but does
|
|
2915 not need to exist at any other time (e.g. it may safely be a temporary
|
|
2916 file).

3713 keeps track of subwindows on a window, these are linked to their

3714 instantiator in the hashtable and when the instantiator goes away
