GMountOperation provides a mechanism for interacting with the user. It can be used for authenticating mountable operations, such as loop mounting files, hard drive partitions or server locations. It can also be used to ask the user questions or show a list of applications preventing unmount or eject operations from completing.

Note that GMountOperation is used for more than just GMount objects – for example it is also used in gDriveStart and gDriveStop.

Users should instantiate a subclass of this that implements all the various callbacks to show the required dialogs, such as GtkMountOperation. If no user interaction is desired (for example when automounting filesystems at login time), usually NULL can be passed, see each method taking a GMountOperation for details.

GMountOperation: Class for providing authentication methods for mounting operations, such as mounting a file locally, or authenticating with a server.

gMountOperation is the equivalent of gMountOperationNew.

GAskPasswordFlags

GAskPasswordFlags are used to request specific information from the user, or to notify the user of their choices in an authentication situation.

need-password: operation requires a password.
need-username: operation requires a username.
need-domain: operation requires a domain.
saving-supported: operation supports saving settings.
anonymous-supported: operation supports anonymous users.

GPasswordSave

GPasswordSave is used to indicate the lifespan of a saved password. Gvfs stores passwords in the Gnome keyring when this flag allows it to, and later retrieves it again from there.

never: never save a password.
for-session: save a password for the session.
permanently: save a password permanently.

GMountOperationResult

GMountOperationResult is returned as a result when a request for information is send by the mounting operation.

handled: The request was fulfilled and the user specified data is now available
aborted: The user requested the mount operation to be aborted
unhandled: The request was unhandled (i.e. not implemented)

aborted(user.data)

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 2.20

user.data: user data set when the signal handler was connected.

ask-password(op, message, default.user, default.domain, flags, user.data)

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 GtkMessageDialog.

op: a GMountOperation requesting a password.
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 GAskPasswordFlags.
user.data: user data set when the signal handler was connected.

ask-question(op, message, choices, user.data)

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 GtkMessageDialog.

op: a GMountOperation asking a question.
message: string containing a message to display to the user.
choices: a list of strings for each possible choice.
user.data: user data set when the signal handler was connected.

reply(op, result, user.data)

Emitted when the user has replied to the mount operation.

op: a GMountOperation.
result: a GMountOperationResult indicating how the request was handled
user.data: user data set when the signal handler was connected.

show-processes(op, message, processes, choices, user.data)

Emitted when one or more processes are blocking an operation e.g. unmounting/ejecting a GMount or stopping a GDrive.

Note that this signal may be emitted several times to update the list of blocking processes as processes close files. The application should only respond with gMountOperationReply to the latest signal (setting "choice" to the choice the user made).

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 GtkMessageDialog. Since 2.22

op: a GMountOperation.
message: string containing a message to display to the user.
processes: a list of GPid for processes blocking the operation.
choices: a list of strings for each possible choice.
user.data: user data set when the signal handler was connected.

anonymous [logical : Read / Write]: Whether to use an anonymous user when authenticating. Default value: FALSE
choice [integer : Read / Write]: The index of the user's choice when a question is asked during the mount operation. See the "ask-question" signal. Allowed values: >= 0 Default value: 0
domain [character : * : Read / Write]: The domain to use for the mount operation. Default value: NULL
password [character : * : Read / Write]: The password that is used for authentication when carrying out the mount operation. Default value: NULL
password-save [GPasswordSave : Read / Write]: Determines if and how the password information should be saved. Default value: G_PASSWORD_SAVE_NEVER
username [character : * : Read / Write]: The user name that is used for authentication when carrying out the mount operation. Default value: NULL
