Directional Pad Configuration Information Structure

The directional pad configuration information structure provides information used during configuration and in interpreting directional pad element data. For each element of kind kISpElementKind_DPad, the device driver fills out a directional pad configuration information structure, which is stored by InputSprocket. A directional pad configuration information structure is defined by the ISpDPadConfigurationInfo data type.

typedef struct {
   UInt32         id;
   Boolean        fourWayPad;
} ISpDPadConfigurationInfo;

Field Description

id

Use this ID to indicate which directional pad to assign first during configuration if the device has more than one directional pad element. A lower value indicates priority. A value of 0 means use the directional pads in any order.

fourWayPad

This value is true if the pad can produce only four directions plus idle.
