Port Terminal to LibGUI. To facilitate listening for action on arbitrary file descriptors, I've added a GNotifier class. It's quite simple but very useful: GNotifier notifier(fd, GNotifier::Read); notifier.on_ready_to_read = [this] (GNotifier& fd) { // read from fd or whatever else you like :^) }; The callback will get invoked by GEventLoop when select() says we have something to read on the fd. 2019-02-10 14:28:39 +01:00			`#include <LibGUI/GNotifier.h>`
