Trait containing all Seat methods.

Seat

Required Methods

fn capabilities(&self) -> SeatCapabilities

Returns the capabilities this Seat currently has.

Returns

the seat capabilities

fn devices(&self, capabilities: SeatCapabilities) -> Vec<Device>

Returns the devices that match the given capabilities.

capabilities

capabilities to get devices for

Returns

A list of GdkDevices. The list must be freed with g_list_free(), the elements are owned by GTK and must not be freed.

fn display(&self) -> Display

Returns the Display this seat belongs to.

Returns

a Display. This object is owned by GTK and must not be freed.

fn keyboard(&self) -> Option<Device>

Returns the device that routes keyboard events.

Returns

a Device with keyboard capabilities. This object is owned by GTK and must not be freed.

fn pointer(&self) -> Option<Device>

Returns the device that routes pointer events.

Returns

a Device with pointer capabilities. This object is owned by GTK and must not be freed.

fn tools(&self) -> Vec<DeviceTool>

Returns all GdkDeviceTools that are known to the application.

Returns

A list of tools. Free with g_list_free().

fn connect_device_added<F: Fn(&Self, &Device) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

Emitted when a new input device is related to this seat.

device

the newly added Device.

fn connect_device_removed<F: Fn(&Self, &Device) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

Emitted when an input device is removed (e.g. unplugged).

device

the just removed Device.

fn connect_tool_added<F: Fn(&Self, &DeviceTool) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

Emitted whenever a new tool is made known to the seat.

The tool may later be assigned to a device (i.e. on proximity with a tablet). The device will emit the signal::Device::tool-changed signal accordingly.

A same tool may be used by several devices.

tool

the new DeviceTool known to the seat

fn connect_tool_removed<F: Fn(&Self, &DeviceTool) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

Emitted whenever a tool is no longer known to this @seat.

tool

the just removed DeviceTool
