### Signal

# Gio FileMonitor::changed

since: 2.0

#### Declaration

    void
    changed (
      GFileMonitor* self,
      GioFile* file,
      GioFile* other_file,
      GFileMonitorEvent event_type,
      gpointer user_data
    )

#### Description

Emitted when `file` has been changed.

If using `G_FILE_MONITOR_WATCH_MOVES` on a directory monitor, and the information is available (and if supported by the backend), `event_type` may be `G_FILE_MONITOR_EVENT_RENAMED`, `G_FILE_MONITOR_EVENT_MOVED_IN` or `G_FILE_MONITOR_EVENT_MOVED_OUT`.

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 `G_FILE_MONITOR_EVENT_MOVED_IN` as equivalent to `G_FILE_MONITOR_EVENT_CREATED` and `G_FILE_MONITOR_EVENT_MOVED_OUT` as equivalent to `G_FILE_MONITOR_EVENT_DELETED`, with extra information. `G_FILE_MONITOR_EVENT_RENAMED` is equivalent to a delete/create pair. This is exactly how the events will be reported in the case that the `G_FILE_MONITOR_WATCH_MOVES` flag is not in use.

If using the deprecated flag `G_FILE_MONITOR_SEND_MOVED` flag and `event_type` is `G_FILE_MONITOR_EVENT_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`.

Default handler: The default handler is called after the handlers added via `g_signal_connect()`.
