DevicePadRef

public struct DevicePadRef : DevicePadProtocol, GWeakCapturing

The DevicePadRef type acts as a lightweight Swift reference to an underlying GdkDevicePad instance. It exposes methods that can operate on this data type through DevicePadProtocol conformance. Use DevicePadRef only as an unowned reference to an existing GdkDevicePad instance.

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. gdk_device_pad_get_n_groups() can be used to obtain the number of groups, gdk_device_pad_get_n_features() and gdk_device_pad_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 gdk_device_pad_get_group_n_modes(), and the current mode for a given group will be notified through the GdkEventPadGroupMode event.
