This is rather tricky - you will have to look through Tcl manuals, e.g.:

http://dev.scriptics.com/man/tcl8.3/TkLib/GetCursor.htm


You find there:

@sourceName maskName fgColor bgColor
    In this form, sourceName and maskName are the names of files describing
cursors for the cursor's source bits and mask. Each file must be in standard
X11 or X10 cursor format. FgColor and bgColor indicate the colors to use for
the cursor, in any of the forms acceptable to Tk_GetColor. This form of the
command will not work on Macintosh or Windows computers.

@sourceName fgColor
    This form is similar to the one above, except that the source is used as
mask also. This means that the cursor's background is transparent. This form
of the command will not work on Macintosh or Windows computers.

@sourceName
    This form only works on Windows, and will load a Windows system cursor
(.ani or .cur) from the file specified in sourceName.
