Struct gdk4::Device

pub struct Device { /* private fields */ }

The Device object represents an input device, such as a keyboard, a mouse, or a touchpad.

See the Seat documentation for more information about the various kinds of devices, and their relationships.

This is an Abstract Base Class, you cannot instantiate it.

Properties

caps-lock-state

Whether Caps Lock is on.

This is only relevant for keyboard devices.

Readable

direction

The direction of the current layout.

This is only relevant for keyboard devices.

Readable

display

The Display the Device pertains to.

Readable | Writeable | Construct Only

has-bidi-layouts

Whether the device has both right-to-left and left-to-right layouts.

This is only relevant for keyboard devices.

Readable

has-cursor

Whether the device is represented by a cursor on the screen.

Readable | Writeable | Construct Only

modifier-state

The current modifier state of the device.

This is only relevant for keyboard devices.

Readable

n-axes

Number of axes in the device.

Readable

name

The device name.

Readable | Writeable | Construct Only

num-lock-state

Whether Num Lock is on.

This is only relevant for keyboard devices.

Readable

num-touches

The maximal number of concurrent touches on a touch device.

Will be 0 if the device is not a touch device or if the number of touches is unknown.

Readable | Writeable | Construct Only

product-id

Product ID of this device.

See DeviceExt::product_id().

Readable | Writeable | Construct Only

scroll-lock-state

Whether Scroll Lock is on.

This is only relevant for keyboard devices.

Readable

seat

Seat of this device.

Readable | Writeable

source

Source type for the device.

Readable | Writeable | Construct Only

tool

The DeviceTool that is currently used with this device.

Readable

vendor-id

Vendor ID of this device.

See DeviceExt::vendor_id().

Readable | Writeable | Construct Only

Signals

changed

Emitted either when the number of either axes or keys changes.

On X11 this will normally happen when the physical device routing events through the logical device changes (for example, user switches from the USB mouse to a tablet); in that case the logical device will change to reflect the axes and keys on the new physical device.

tool-changed

Emitted on pen/eraser devices whenever tools enter or leave proximity.

Implementations

impl Device

pub const NONE: Option<&'static Device> = None

Trait Implementations

impl Clone for Device

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Device

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Device

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl HasParamSpec for Device

type ParamSpec = ParamSpecObject

type SetValue = Device

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, Device>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for Device

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Device

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl ParentClassIs for Device

type Parent = Object

impl<OT: ObjectType> PartialEq<OT> for Device

fn eq(&self, other: &OT) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<OT: ObjectType> PartialOrd<OT> for Device

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for Device

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for Device

impl IsA<Device> for DevicePad
