defcur(3G)defcur(3G)NAMEdefcur - 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.
DESCRIPTIONdefcur 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.
SEE ALSO

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.
