InetAddressMask

GInetAddressMask represents a range of IPv4 or IPv6 addresses described by a base address and a length indicating how many bits of the base address are relevant for matching purposes. These are often given in string form. For example, 10.0.0.0/8, or fe80::/10.

Items can be grouped in sections, and may have submenus associated with them. Both items and sections usually have some representation data, such as labels or icons. The type of the associated action (ie whether it is stateful, and what kind of state it has) can influence the representation of the item.

since: 2.32

MountOperation

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.
