class: DevicePad

[25:7] extends: object

An interface for tablet pad devices. 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. [method@Gdk.DevicePad.get_n_groups] can be used to obtain the number of groups, [method@Gdk.DevicePad.get_n_features] and [method@Gdk.DevicePad.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 [method@Gdk.DevicePad.get_group_n_modes], and the current mode for a given group will be notified through events of type GDK_PAD_GROUP_MODE.

Methods

• DevicePad (Handle = null)

  Creates a new DevicePad by wrapping a native handle or another wrapper.

  • @p Handle is the native handle or another wrapper whose handle to adopt.

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.

  • @r A string.

• get_feature_group (string feature, int feature_idx)

  Returns the group the given @feature and @idx belong to. f the feature or index do not exist in @pad, -1 is returned.

  • @p feature is the feature type to get the group from.
  • @p feature_idx is the index of the feature to get the group from.

• get_group_n_modes (int group_idx)

  Returns the number of modes that @group may have.

  • @p group_idx is group to get the number of available modes from.

• get_n_features (string feature)

  Returns the number of features a tablet pad has.

  • @p feature is a pad feature.

• get_n_groups ()

  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.
