GdkDevicePad is an interface implemented by devices of type GDK_SOURCE_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. Device.padGetNGroups can be used to obtain the number of groups, Device.padGetNFeatures and Device.padGetFeatureGroup 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 Device.padGetGroupNModes, and the current mode for a given group will be notified through the GdkEventPadGroupMode event.



GdkDevicePad* getDevicePadStruct(bool transferOwnership = false)

Get the main Gtk struct

int getFeatureGroup(GdkDevicePadFeature feature, int featureIdx)

Returns the group the given feature and idx belong to, or -1 if feature/index do not exist in pad.

int getGroupNModes(int groupIdx)

Returns the number of modes that group may have.

int getNFeatures(GdkDevicePadFeature feature)

Returns the number of features a tablet pad has.

int getNGroups()

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.
