# Tcl/Tk 8.5+ feature
# --------------------------------------------------------------
# In the future release, I want to support to embed the 'win'
# into the container which has window-id 'use-id'.
# It may give users frexibility on controlling their GUI.
# However, it may be difficult for current Tcl/Tk (Tcl/Tk8.5.1),
# because it seems to require to modify Tcl/Tk's source code.
