XCreatePixmapCursor()													     XCreatePixmapCursor()

Name
  XCreatePixmapCursor - create a cursor from two bitmaps.

Synopsis
  Cursor XCreatePixmapCursor(display, source, mask, foreground_color,
  background_color, x, y)
	Display *display;
	Pixmap source;
	Pixmap mask;
	XColor *foreground_color;
	XColor *background_color;
	unsigned int x, y;

Arguments
  display   Specifies a connection to an X server; returned from XOpenDisplay().

  source    Specifies the shape of the source cursor.  A pixmap of depth 1.

  mask	    Specifies the bits of the cursor that are to be displayed (the mask or stipple).  A pixmap of depth 1.  May be None.

  foreground_color
	    Specifies the red, green, and blue (RGB) values for the foreground.

  background_color
	    Specifies the red, green, and blue (RGB) values for the background.

  x	    Specify the coordinates of the cursor's hotspot relative to the source's origin.  Must be a point within the source.
  y
Returns
  The created cursor.

Description
  XCreatePixmapCursor()  creates  a  cursor  and  returns  a  cursor  ID.  Foreground and background RGB values must be specified using fore-
  ground_color and background_color, even if the server only has a monochrome screen.  The foreground_color is used for the  1	bits  in  the
  source, and the background is used for the 0 bits.  Both source and mask (if specified) must have depth 1, but can have any root.  The mask
  pixmap defines the shape of the cursor; that is, the 1 bits in the mask define which source pixels will be displayed.  If no mask is given,
  all pixels of the source are displayed.  The mask, if present, must be the same size as the source.

  The pixmaps can be freed immediately if no further explicit references to them are to be made.

  For more information on cursors, see Volume One, Chapter 6, Drawing Graphics and Text.

Structures
     typedef struct {
	 unsigned long pixel;
	 unsigned short red, green, blue;
	 char flags;	/* DoRed, DoGreen, DoBlue */
	 char pad;
     } XColor;

Errors
  BadAlloc

  BadMatch  Mask bitmap must be the same size as source bitmap.

  BadPixmap

NAME

       XCreateFontCursor, XCreatePixmapCursor, XCreateGlyphCursor - create cursors

SYNOPSIS

       #include <X11/cursorfont.h>

       Cursor XCreateFontCursor(display, shape)
	       Display *display;
	       unsigned int shape;

       Cursor XCreatePixmapCursor(display, source, mask, foreground_color, background_color, x, y)
	       Display *display;
	       Pixmap source;
	       Pixmap mask;
	       XColor *foreground_color;
	       XColor *background_color;
	       unsigned int x, y;

       Cursor XCreateGlyphCursor(display, source_font, mask_font, source_char, mask_char, foreground_color, background_color)
	       Display *display;
	       Font source_font, mask_font;
	       unsigned int source_char, mask_char;
	       XColor *foreground_color;
	       XColor *background_color;

ARGUMENTS

       Specifies  the  RGB  values  for the background of the source.  Specifies the connection to the X server.  Specifies the RGB values for the
       foreground of the source.  Specifies the cursor's source bits to be displayed or None.  Specifies the glyph character for the mask.  Speci-
       fies  the  font	for  the mask glyph or None.  Specifies the shape of the cursor.  Specifies the shape of the source cursor.  Specifies the
       character glyph for the source.	Specifies the font for the source glyph.  Specify the x and y coordinates, which indicate the hotspot rel-
       ative to the source's origin.

DESCRIPTION

       X  provides  a  set  of standard cursor shapes in a special font named cursor.  Applications are encouraged to use this interface for their
       cursors because the font can be customized for the individual display type. The shape argument specifies which glyph of the standard  fonts
       to use.

       The  hotspot  comes from the information stored in the cursor font. The initial colors of a cursor are a black foreground and a white back-
       ground (see XRecolorCursor(3X11)).

       XCreateFontCursor can generate BadAlloc and BadValue errors.

       The XCreatePixmapCursor function creates a cursor and returns the cursor ID associated with it. The foreground and  background  RGB  values
       must  be  specified  using foreground_color and background_color, even if the X server only has a StaticGray or GrayScale screen. The fore-
       ground color is used for the pixels set to 1 in the source, and the background color is used for the pixels set to 0. Both source and mask,
       if  specified,  must have depth one (or a BadMatch error results) but can have any root. The mask argument defines the shape of the cursor.
       The pixels set to 1 in the mask define which source pixels are displayed, and the pixels set to 0 define which pixels are  ignored.  If	no
       mask  is  given,  all  pixels  of the source are displayed. The mask, if present, must be the same size as the pixmap defined by the source
       argument, or a BadMatch error results. The hotspot must be a point within the source, or a BadMatch error results.

       The components of the cursor can be transformed arbitrarily to meet display limitations. The pixmaps can be freed immediately if no further
       explicit  references  to  them are to be made. Subsequent drawing in the source or mask pixmap has an undefined effect on the cursor. The X
       server might or might not make a copy of the pixmap.

       XCreatePixmapCursor can generate BadAlloc and BadPixmap errors.

       The XCreateGlyphCursor function is similar to XCreatePixmapCursor except that the source and mask bitmaps are obtained from  the  specified
       font  glyphs. The source_char must be a defined glyph in source_font, or a BadValue error results. If mask_font is given, mask_char must be
       a defined glyph in mask_font, or a BadValue error results. The mask_font and character are optional. The origins  of  the  source_char  and
       mask_char  (if  defined)  glyphs are positioned coincidentally and define the hotspot. The source_char and mask_char need not have the same
       bounding box metrics, and there is no restriction on the placement of the hotspot relative to the bounding boxes. If no mask_char is given,
       all  pixels  of the source are displayed. You can free the fonts immediately by calling XFreeFont if no further explicit references to them
       are to be made.

       For 2-byte matrix fonts, the 16-bit value should be formed with the byte1 member in the most significant byte and the byte2 member  in  the
       least significant byte.

       XCreateGlyphCursor can generate BadAlloc, BadFont, and BadValue errors.

DIAGNOSTICS

       The  server  failed  to	allocate the requested resource or server memory.  A value for a Font or GContext argument does not name a defined
       Font.  Some argument or pair of arguments has the correct type and range but fails to match in some other way required by the  request.	 A
       value  for a Pixmap argument does not name a defined Pixmap.  Some numeric value falls outside the range of values accepted by the request.
       Unless a specific range is specified for an argument, the full range defined by the argument's type is accepted.  Any argument defined as a
       set of alternatives can generate this error.
