Trait containing all DeviceMonitor methods.

Implementors

crate::DeviceMonitor

Required methods

fn bus(&self) -> Bus[src]

Gets the crate::Bus of this crate::DeviceMonitor

Returns

a crate::Bus

fn devices(&self) -> Vec<Device>[src]

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

Returns

a [crate::glib::List] of crate::Device

fn providers(&self) -> Vec<GString>[src]

Get a list of the currently selected device provider factories.

This

Returns

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

fn shows_all_devices(&self) -> bool[src]

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

Returns

true when all devices will be shown.

fn set_show_all_devices(&self, show_all: bool)[src]

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

show all devices

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

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

Returns

true if the device monitoring could be started

fn stop(&self)[src]

Stops monitoring the devices.

fn shows_all(&self) -> bool[src]

fn set_show_all(&self, show_all: bool)[src]

fn connect_show_all_notify<F: Fn(&Self) + Send + Sync + 'static>(
    &self,
    f: F
) -> SignalHandlerId[src]
