|
|
* @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.
