Emitted when file has been changed.
If using [gio.types.FileMonitorFlags.WatchMoves] on a directory monitor, and the information is available (and if supported by the backend), event_type may be [gio.types.FileMonitorEvent.Renamed], [gio.types.FileMonitorEvent.MovedIn] or [gio.types.FileMonitorEvent.MovedOut].
In all cases file will be a child of the monitored directory. For renames, file will be the old name and other_file is the new name. For "moved in" events, file is the name of the file that appeared and other_file is the old name that it was moved from (in another directory). For "moved out" events, file is the name of the file that used to be in this directory and other_file is the name of the file at its new location.
It makes sense to treat [gio.types.FileMonitorEvent.MovedIn] as equivalent to [gio.types.FileMonitorEvent.Created] and [gio.types.FileMonitorEvent.MovedOut] as equivalent to [gio.types.FileMonitorEvent.Deleted], with extra information. [gio.types.FileMonitorEvent.Renamed] is equivalent to a delete/create pair. This is exactly how the events will be reported in the case that the [gio.types.FileMonitorFlags.WatchMoves] flag is not in use.
If using the deprecated flag [gio.types.FileMonitorFlags.SendMoved] flag and event_type is [gio.types.FileMonitorEvent.Moved], file will be set to a #GFile containing the old path, and other_file will be set to a #GFile containing the new path.
In all the other cases, other_file will be set to #NULL.
