DevicePad

class DevicePad(*args, **kwargs)

GdkDevicePad is an interface implemented by devices of type TABLET_PAD

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. get_n_groups can be used to obtain the number of groups, get_n_features and get_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 get_group_n_modes, and the current mode for a given group will be notified through events of type GDK_PAD_GROUP_MODE.

Methods

class DevicePad

get_feature_group(feature: DevicePadFeature, feature_idx: int) → int

Returns the group the given feature and idx belong to.

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

Parameters:

• feature – the feature type to get the group from

• feature_idx – the index of the feature to get the group from

get_group_n_modes(group_idx: int) → int

Returns the number of modes that group may have.

Parameters:

group_idx – group to get the number of available modes from

get_n_features(feature: DevicePadFeature) → int

Returns the number of features a tablet pad has.

Parameters:

feature – a pad feature

get_n_groups() → int

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.
