DevicePad

open class DevicePad : Device, DevicePadProtocol

The DevicePad type acts as a reference-counted owner of an underlying GdkDevicePad instance. It provides the methods that can operate on this data type through DevicePadProtocol conformance. Use DevicePad as a strong reference or owner of a 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. [methodGdk.DevicePad.get_n_groups] can be used to obtain the number of groups, [methodGdk.DevicePad.get_n_features] and [methodGdk.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 [methodGdk.DevicePad.get_group_n_modes], and the current mode for a given group will be notified through events of type GDK_PAD_GROUP_MODE.

  • Designated initialiser from the underlying `C` data type.

    This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the DevicePad instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafeMutablePointer<GdkDevicePad>)

    Parameters

    op

    pointer to the underlying object

  • Designated initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the DevicePad instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafePointer<GdkDevicePad>)

    Parameters

    op

    pointer to the underlying object

  • Optional initialiser from a non-mutating gpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the DevicePad instance.

    Declaration

    Swift

    @inlinable
override public init!(gpointer op: gpointer?)

    Parameters

    op

    gpointer to the underlying object

override public init!(gconstpointer op: gconstpointer?)

    Parameters
