Trait containing all DeviceMonitor methods.

Implementors

DeviceMonitor

Required methods

`fn get_bus(&self) -> Bus`

Gets the Bus of this DeviceMonitor

Returns

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.

Returns

a glib::List of Device

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

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 get_show_all_devices(&self) -> bool`

Get if self is curretly 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)`

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>`

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.
