SYNOPSISupdate ?options?
DESCRIPTION
Changes made via Tk commands do not become visible until a call to
update. Update flushes any pending changes to the screen. The follow‐
ing options are supported:
-disable
If this option is given, all updates are disabled. This is use‐
ful to enable a program to stop mouse movement causing automatic
updates while it is making changes to the window.
-enable
This reverses a previous update-enable invocation.
BUGS
Changes that affect window sizes are visible immediately.
