Trait containing all DeviceMonitor methods.



Required methods

fn get_bus(&self) -> Bus

Gets the Bus of this DeviceMonitor


a Bus

fn get_devices(&self) -> Vec<Device>

Gets a list of devices from all of the relevant monitors. This may actually probe the hardware if the monitor is not currently started.


a glib::List of Device

fn get_providers(&self) -> Vec<GString>

Get a list of the currently selected device provider factories.



A list of device provider factory names that are currently being monitored by self or None when nothing is being monitored.

fn get_show_all_devices(&self) -> bool

Get if self is currently showing all devices, even those from hidden providers.


true when all devices will be shown.

fn set_show_all_devices(&self, show_all: bool)

Set if all devices should be visible, even those devices from hidden providers. Setting show_all to true might show some devices multiple times.


show all devices

fn start(&self) -> Result<(), BoolError>

Starts monitoring the devices, one this has succeeded, the MessageType::DeviceAdded and MessageType::DeviceRemoved messages will be emitted on the bus when the list of devices changes.


true if the device monitoring could be started

fn stop(&self)

Stops monitoring the devices.

fn get_property_show_all(&self) -> bool

fn set_property_show_all(&self, show_all: bool)

fn connect_property_show_all_notify<F: Fn(&Self) + Send + Sync + 'static>(
    f: F
) -> SignalHandlerId
