FileMonitor

Monitors a file or directory for changes.

To obtain a `GFileMonitor` for a file or directory, use [method@Gio.File.monitor], [method@Gio.File.monitor_file], or [ method@Gio.File.monitor_directory].

To get informed about changes to the file or directory you are monitoring, connect to the [signal@Gio.FileMonitor:GFileMonitor:changed ] signal. The signal will be emitted in the thread-default main context (see [method@GLib.MainContext.push_thread_default]) of the thread that the monitor was created in (though if the global default main context is blocked, this may cause notifications to be blocked even if the thread-default context is still running).

Example: File monitoring:

public static int main () {
	try {
		File file = File.new_for_path (Environment.get_home_dir ());
		FileMonitor monitor = file.monitor (FileMonitorFlags.NONE, null);
		print ("Monitoring: %s\n", file.get_path ());

		monitor.changed.connect ((src, dest, event) => {
			if (dest != null) {
				print ("%s: %s, %s\n", event.to_string (), src.get_path (), dest.get_path ());
			} else {
				print ("%s: %s\n", event.to_string (), src.get_path ());
			}
		});

		new MainLoop ().run ();
	} catch (Error err) {
		print ("Error: %s\n", err.message);
	}
	return 0;
}
