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 11:28:39 -02:00			`#include <LibGUI/GNotifier.h>`

LibGUI: Implement nested event loops to support dialog boxes. This patch adds a simple GMessageBox that can run in a nested event loop. Here's how you use it: GMessageBox box("Message text here", "Message window title"); int result = box.exec(); The next step is to make the WindowServer respect the modality flag of these windows and prevent interaction with other windows in the same process until the modal window has been closed. 2019-03-18 20:01:02 -03:00			`GEventLoop::register_notifier(Badge<GNotifier>(), *this);`
