## Detailed Description

Authentication methods for mountable locations.

MountOperation provides a mechanism for authenticating mountable operations, such as loop mounting files, hard drive partitions or server locations.

Mounting operations are handed a MountOperation that they can use if they require any privileges or authentication for their volumes to be mounted (e.g. a hard disk partition or an encrypted filesystem), or if they are implementing a remote server protocol which requires user credentials such as FTP or WebDAV.

Developers should instantiate a subclass of this that implements all the various callbacks to show the required dialogs.

Glib::SignalProxy< void > Gio::MountOperation::signal_aborted | ( |  | ) |

Slot Prototype:
  `void on_my_aborted()`

Flags: Run Last

Emitted by the backend when e.g. a device becomes unavailable while a mount operation is in progress.

Implementations of GMountOperation should handle this signal by dismissing open password dialogs.

Since glibmm 2.20:

Glib::SignalProxy< void,const Glib::ustring&,const Glib::ustring&,const Glib::ustring&,AskPasswordFlags > Gio::MountOperation::signal_ask_password | ( |  | ) |

Slot Prototype:
  `void on_my_ask_password(const Glib::ustring& message, const Glib::ustring& default_user, const Glib::ustring& default_domain, AskPasswordFlags flags)`

Flags: Run Last

Emitted when a mount operation asks the user for a password.

If the message contains a line break, the first line should be presented as a heading. For example, it may be used as the primary text in a Gtk::MessageDialog.

Parameters

  message | String containing a message to display to the user.
  default_user | String containing the default user name.
  default_domain | String containing the default domain.
  flags | A set of AskPasswordFlags.

Glib::SignalProxy< void,const Glib::ustring&,const Glib::StringArrayHandle& > Gio::MountOperation::signal_ask_question | ( |  | ) |

Slot Prototype:
  `void on_my_ask_question(const Glib::ustring& message, const Glib::StringArrayHandle& choices)`

Flags: Run Last

Emitted when asking the user a question and gives a list of choices for the user to choose from.

If the message contains a line break, the first line should be presented as a heading. For example, it may be used as the primary text in a Gtk::MessageDialog.

Parameters

  message | String containing a message to display to the user.
  choices | An array of strings for each possible choice.

Glib::SignalProxy< void,MountOperationResult > Gio::MountOperation::signal_reply | ( |  | ) |

Slot Prototype:
  `void on_my_reply(MountOperationResult result)`

Flags: Run Last

Emitted when the user has replied to the mount operation.

Parameters

  result | A MountOperationResult indicating how the request was handled.

Glib::SignalProxy< void,const Glib::ustring&,gint64,gint64 > Gio::MountOperation::signal_show_unmount_progress | ( |  | ) |

Slot Prototype:
  `void on_my_show_unmount_progress(const Glib::ustring& message, gint64 time_left, gint64 bytes_left)`

Flags: Run Last

Emitted when an unmount operation has been busy for more than some time (typically 1.5 seconds).

When unmounting or ejecting a volume, the kernel might need to flush pending data in its buffers to the volume stable storage, and this operation can take a considerable amount of time. This signal may be emitted several times as long as the unmount operation is outstanding, and then one last time when the operation is completed, with bytes_left set to zero.

Implementations of GMountOperation should handle this signal by showing an UI notification, and then dismiss it, or show another notification of completion, when bytes_left reaches zero.

If the message contains a line break, the first line should be presented as a heading. For example, it may be used as the primary text in a Gtk::MessageDialog.

Since glibmm 2.34:

Parameters

  message | String containing a mesage to display to the user.
  time_left | The estimated time left before the operation completes, in microseconds, or -1.
  bytes_left | The amount of bytes to be written before the operation completes (or -1 if such amount is not known), or zero if the operation is completed.
