defcur(3G)

NAME
     defcur - defines a cursor glyph

FORTRAN 77 SPECIFICATION
     subroutine defcur(n, curs)
     integer*4 n
     integer*2 curs(*)

PARAMETERS
     n      expects the constant you want to assign as a cursor name. By
            default, an arrow is defined as cursor 0 and cannot be redefined.

     curs   expects the bitmap for the cursor you want to define.  The bitmap
            can be 16x16 or 32x32 and either one or two layers deep. This
            parameter is ignored for cross-hair cursors.

DESCRIPTION
     defcur defines a cursor glyph with the specified name and bitmap. Call
     cursty prior to calling defcur to set the type and size of cursor it
     defines.  The name parameter n is used to identify the cursor glyph to
     other cursor routines.  A subsequent call to defcur with the same value
     of n will replace the current definition of the cursor with the new one.

     By default, the cursor origin of a bitmap cursor is at (0,0), its lower-
     left corner, and the cursor origin of a cross-hair cursor is at (15,15),
     the intersection of its two lines.  Use curori to set the cursor origin
     to somewhere else.  The cursor origin is the position controlled by
     valuators attached to the cursor, and is also the position pick uses for
     the picking region.

NOTES
     This routine is available only in immediate mode.

     Some models do not support two-layer cursor bitmaps.  Use the getgde
     inquiry GDBCUR to determine how many layers are supported.
