DevicePad

Provided Methods§

Source

fn feature_group(&self, feature: DevicePadFeature, feature_idx: i32) -> i32

Returns the group the given @feature and @idx belong to.

f the feature or index do not exist in @self, -1 is returned.

§feature

the feature type to get the group from

§feature_idx

the index of the feature to get the group from

§Returns

The group number of the queried pad feature.

Source

fn group_n_modes(&self, group_idx: i32) -> i32

Returns the number of modes that @group may have.

§group_idx

group to get the number of available modes from

§Returns

The number of modes available in @group.

Source

fn n_features(&self, feature: DevicePadFeature) -> i32

Returns the number of features a tablet pad has.

§feature

a pad feature

§Returns

The amount of elements of type @feature that this pad has.

Source

fn n_groups(&self) -> i32

Returns the number of groups this pad device has.

Pads have at least one group. A pad group is a subcollection of buttons/strip/rings that is affected collectively by a same current mode.

§Returns

The number of button/ring/strip groups in the pad.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
