Hi Tony,

According to the manual, this command waits (forever) for the window to
become fully visible. I don't like it much, its just sugaring the
events...the nicer command is binding (bind command) to the window, on the
visibility event. This event is supported under tk4.2 so it should work with
Erlang/ETk

Using that command you can execute a fun whenever the visibility changes(I
guess, my manuals not clear), so you could bind, go into a receive loop,
then unbind.

How does that sound?
