func (*Backend) EmitBitBoxBaseDetected

func (backend *Backend) EmitBitBoxBaseDetected()

EmitBitBoxBaseDetected saves the IP and Hostname of detected BitBox Bases at this backend

func (*Backend) Events

func (backend *Backend) Events() <-chan interface{}

Events returns the push notifications channel.

func (*Backend) Keystores

func (backend *Backend) Keystores() *keystore.Keystores

Keystores returns the keystores registered at this backend.

func (*Backend) NotifyUser

func (backend *Backend) NotifyUser(text string)

NotifyUser creates a desktop notification.

func (*Backend) OnAccountInit

func (backend *Backend) OnAccountInit(f func(accounts.Interface))

OnAccountInit installs a callback to be called when an account is initialized.

OnBitBoxBaseInit installs a callback to be called when a bitboxbase is initialized.

func (*Backend) OnBitBoxBaseUninit

func (backend *Backend) OnBitBoxBaseUninit(f func(string))

OnBitBoxBaseUninit installs a callback to be called when a bitboxbase is uninitialized.

func (*Backend) OnDeviceInit
