# xmfbox.tcl --
#
#       Implements the "Motif" style file selection dialog for the
#       Unix platform. This implementation is used only if the
#       "::tk_strictMotif" flag is set.

# ::tk::MotifFDialog --
#
#       Implements a file dialog similar to the standard Motif file
#       selection box.
#
# Arguments:
#       type            "open" or "save"
#       args            Options parsed by the procedure.
#
# Results:
#       When -multiple is set to 0, this returns the absolute pathname
#       of the selected file. (NOTE: This is not the same as a single
#       element list.)
# 
#       When -multiple is set to > 0, this returns a Tcl list of absolute
#       pathnames. The argument for -multiple is ignored, but for consistency
#       with Windows it defines the maximum amount of memory to allocate for
#       the returned filenames.

#       argList         Options parsed by the procedure.
