tkwait - Wait for variable to change or window to be destroyed

<H3><A NAME="M4">DESCRIPTION</A></H3>
The <B>tkwait</B> command waits for one of several things to happen,
then it returns without taking any other actions.
The return value is always an empty string.
If the first argument is <B><A HREF="../TclCmd/variable.htm">variable</A></B> (or any abbreviation of
it) then the second argument is the name of a global variable and the
command waits for that variable to be modified.
If the first argument is <B>visibility</B> (or any abbreviation
of it) then the second argument is the name of a window and the
<B>tkwait</B> command waits for a change in its
visibility state (as indicated by the arrival of a VisibilityNotify
event).  This form is typically used to wait for a newly-created
window to appear on the screen before taking some action.
If the first argument is <B>window</B> (or any abbreviation
of it) then the second argument is the name of a window and the
<B>tkwait</B> command waits for that window to be destroyed.
This form is typically used to wait for a user to finish interacting
with a dialog box before using the result of that interaction.
<P>
While the <B>tkwait</B> command is waiting it processes events in
the normal fashion, so the application will continue to respond
to user interactions.
If an event handler invokes <B>tkwait</B> again, the nested call
to <B>tkwait</B> must complete before the outer call can complete.
