Struct gdk4::DevicePad

#[repr(transparent)]
pub struct DevicePad { /* private fields */ }

DevicePad is an interface implemented by devices of type InputSource::TabletPad

It allows querying the features provided by the pad device.

Tablet pads may contain one or more groups, each containing a subset of the buttons/rings/strips available. DevicePadExt::n_groups() can be used to obtain the number of groups, DevicePadExt::n_features() and DevicePadExt::feature_group() can be combined to find out the number of buttons/rings/strips the device has, and how are they grouped.

Each of those groups have different modes, which may be used to map each individual pad feature to multiple actions. Only one mode is effective (current) for each given group, different groups may have different current modes. The number of available modes in a group can be found out through DevicePadExt::group_n_modes(), and the current mode for a given group will be notified through events of type GDK_PAD_GROUP_MODE.

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

Trait Implementations

impl Clone for DevicePad

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 DevicePad

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

Formats the value using the given formatter.

impl Display for DevicePad

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

Formats the value using the given formatter.

impl HasParamSpec for DevicePad

type ParamSpec = ParamSpecObject

type SetValue = DevicePad

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for DevicePad

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 DevicePad

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

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

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 DevicePad

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 DevicePad

fn static_type() -> Type

Returns the type identifier of Self.
