Detailed Description

Pad device interface.

Gdk::DevicePad is an interface implemented by devices of type Gdk::InputSource::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 the Gdk::EventPadGroupMode event.

Since gtkmm 3.96:

Member Function Documentation

static void Gdk::DevicePad::add_interface ( GType  gtype_implementer)
static
int Gdk::DevicePad::get_feature_group ( Feature  feature,
int  feature_idx 
) const

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

Parameters
featureThe feature type to get the group from.
feature_idxThe index of the feature to get the group from.
Returns
The group number of the queried pad feature.
int Gdk::DevicePad::get_group_n_modes ( int  group_idx) const

Returns the number of modes that group may have.

Parameters
group_idxGroup to get the number of available modes from.
Returns
The number of modes available in group.
int Gdk::DevicePad::get_n_features ( Feature  feature) const

Returns the number of features a tablet pad has.

Parameters
featureA pad feature.
Returns
The amount of elements of type feature that this pad has.
int Gdk::DevicePad::get_n_groups ( ) const

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.

Returns
The number of button/ring/strip groups in the pad.
