# Example:
#	
#	tixScrolledWindow .w
#	set window [.w subwidget window]
#		# Now you can put a whole widget hierachy inside $window.
#		#
#	button $window.b
#	pack $window.b
#
# Author's note
#
# Note, the current implementation does not allow the child window
# to be outside of the parent window when the parent's size is larger
# than the child's size. This is fine for normal operations. However,
# it is not suitable for an MDI master window. Therefore, you will notice
# that the MDI master window is not a subclass of ScrolledWidget at all.
