Hi,

     I am trying to draw Indic text onto a Squeak's subwindow from an
external DLL using FFI.

     How do I know that it is time to REdraw the text. Such as when an
overlapping window goes away or the window is unminimized. Is there
some event I can respond to. Since drawing is done externally I think
I must also be able to respond to unminimization of the main Squeak
window. etc.

Thank You,
++imanshu.
