UPDATE(9) UPDATE(9)
NAME
update - flush graphics
SYNOPSIS
update ?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 following options are supported:
-disable
If this option is given, all updates are disabled.
This is useful to enable a program to stop mouse move-
ment 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.
