Description:

[ Version ( since = "2.18" ) ]
public FileMonitor monitor (FileMonitorFlags flags, Cancellable? cancellable = null) throws Error

Obtains a file or directory monitor for the given file, depending on the type of the file.

If cancellable is not null, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error g_io_error_cancelled will be returned.

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);
}
