The
with-atomic-redisplay
macro delays the updating of specified panes until all state changes have been performed.
Most CAPI pane slot writers update the visual appearance of the pane at the point that their state changes, but it is sometimes necessary to cause all updates to the pane to be left until after they are all completed. The macro
with-atomic-redisplay
defers all visible changes to the state of each pane in
panes
until the end of the scope of the macro.
