Gio.MountOperation::show-unmount-progress

connect('show-unmount-progress', function (mountOperation, message: String, time_left: Number(gint64), bytes_left: Number(gint64), ): void);

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 #GtkMessageDialog.

Since 2.34

mountOperation: instance of Gio.MountOperation that is emitting the signal
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
