-# ON-DESTROYING ON-READY

# Then the main code will call ON-DESTROYING just before
# destroying the inner window and recreating it, and
# [concat ON-READY [list ORIENTATION]]
# just after. The inner window to use is called .i.i.b.
#
+# This uses variables, in the applet namespace,
+# w h border_colour border_width deforient
+# These should be set before setup-subwindow is called and not
+# modified thereafter.
+#
# The user of the subwindow machinery may call
# applet::subwindow-need-recreate
# if for any reason the inner window should be destroyed and recreated.
#
# Alternatively, it may request that a subprocess be spawned
# repeatedly with the xid of a suitable window.
