NAME

       tickit_term_observe_sigwinch - react to the SIGWINCH signal

SYNOPSIS

       #include <tickit.h>

       void tickit_term_observe_sigwinch(TickitTerm *tt, bool observe);

       Link with -ltickit.

DESCRIPTION

       tickit_term_observe_sigwinch()  controls  a setting on the TickitTerm instance that allows
       it to be  informed  when  the  process  receives  a  SIGWINCH  signal,  meaning  that  the
       controlling terminal may have changed size.

       When  this  flag  is enabled on at least one terminal instance, a handler for the SIGWINCH
       signal is automatically installed by libtickit  itself.  On  receipt  of  the  signal  the
       handler  will mark a flag on any TickitTerm instance that is observing it to indicate that
       the window may have changed size. The next time these  instances  invoke  any  of  several
       input-related functions (listed below), this flag will cause the function to first perform
       the actions of  tickit_term_refresh_size(3).  This  deferred  handling  ensures  that  the
       TICKIT_EV_RESIZE  event  is only invoked at a time when the application is expecting input
       events, and not asynchronously during the signal handler itself.

       Note that use of this ability requires giving control of the process-wide SIGWINCH  signal
       to  the  libtickit  library. If this is not suitable, the process should arrange to invoke
       tickit_term_refresh_size() at an appropriate time by some other mechanism.
