Class Details¶

class FPrint.Context(**kwargs)¶

Bases:: GObject.Object
Abstract:: No
Structure:: FPrint.ContextClass

classmethod new()¶

Returns:: a newly created FPrint.Context
Return type:: FPrint.Context

Create a new FPrint.Context.

enumerate()¶: Enumerate all devices. You should call this function exactly once at startup. Please note that it iterates the mainloop until all devices are enumerated.

get_devices()¶

Returns:: a new GLib.PtrArray of FPrint.Device's.
Return type:: [FPrint.Device]

Get all devices. FPrint.Context.enumerate() will be called as needed.

do_device_added(device) virtual¶

Parameters:: device (FPrint.Device) –

Called when a new device is added

do_device_removed(device) virtual¶

Parameters:: device (FPrint.Device) –

Called when a device is removed

Signal Details¶

FPrint.Context.signals.device_added(context, device)¶

Signal Name:

device-added

Flags:

RUN_LAST

Parameters:

context (FPrint.Context) – The object which received the signal
device (FPrint.Device) – A FPrint.Device

This signal is emitted when a fingerprint reader is added.

FPrint.Context.signals.device_removed(context, device)¶

Signal Name:

device-removed

Flags:

RUN_LAST

Parameters:

context (FPrint.Context) – The object which received the signal
device (FPrint.Device) – A FPrint.Device

This signal is emitted when a fingerprint reader is removed.

It is guaranteed that the device has been closed before this signal is emitted. See the FPrint.Device removed signal documentation for more information.
