/**
* SECTION:gdkdevicepad
* @Short_description: Pad device interface
* @Title: GtkDevicePad
*
* #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.
