Defines input events and associated data types.
Identifies possible input subsystem types. The types of events that each device type produces correspond to SbInputEventType
values.
kSbInputDeviceTypeGesture
Input from a gesture-detection mechanism. Examples include Kinect, Wiimotes, etc...
Produces Move
, Press
and Unpress
events.
kSbInputDeviceTypeGamepad
Input from a gamepad, following the layout provided in the W3C Web Gamepad API. [ https://www.w3.org/TR/gamepad/ ]
Produces Move
, Press
and Unpress
events.
kSbInputDeviceTypeKeyboard
Keyboard input from a traditional keyboard or game controller chatpad.
Produces Press
and Unpress
events.
kSbInputDeviceTypeMouse
Input from a traditional mouse.
Produces Move
, Press
, and Unpress
events.
kSbInputDeviceTypeRemote
Input from a TV remote-control-style device.
Produces Press
and Unpress
events.
kSbInputDeviceTypeTouchScreen
Input from a single- or multi-touchscreen.
Produces Move
, Press
, and Unpress
events.
kSbInputDeviceTypeTouchPad
Input from a touchpad that is not masquerading as a mouse.
Produces Move
, Press
, and Unpress
events.
kSbInputDeviceTypeOnScreenKeyboard
Keyboard input from an on screen keyboard.
Produces Input
events.
The action that an input event represents.
kSbInputEventTypeMove
Device Movement. In the case of Mouse
, and perhaps Gesture
, the movement tracks an absolute cursor position. In the case of TouchPad
, only relative movements are provided.
kSbInputEventTypePress
Key or button press activation. This could be a key on a keyboard, a button on a mouse or game controller, a push from a touch screen, or a gesture. An Unpress
event is subsequently delivered when the Press
event terminates, such as when the key/button/finger is raised. Injecting repeat presses is up to the client.
kSbInputEventTypeUnpress
Key or button deactivation. The counterpart to the Press
event, this event is sent when the key or button being pressed is released.
kSbInputEventTypeWheel
Wheel movement. Provides relative movements of the Mouse
wheel.
kSbInputEventTypeInput
Event data for kSbEventTypeInput
events.
SbWindow window
The window in which the input was generated.
SbInputEventType type
The type of input event that this represents.
SbInputDeviceType device_type
The type of device that generated this input event.
int device_id
An identifier that is unique among all connected devices.
SbKey key
An identifier that indicates which keyboard key or mouse button was involved in this event, if any. All known keys for all devices are mapped to a single ID space, defined by the SbKey
enum in key.h
.
wchar_t character
The character that corresponds to the key. For an external keyboard, this character also depends on the keyboard language. The value is 0
if there is no corresponding character.
SbKeyLocation key_location
The location of the specified key, in cases where there are multiple instances of the button on the keyboard. For example, some keyboards have more than one “shift” key.
unsigned int key_modifiers
Key modifiers (e.g. Ctrl
, Shift
) held down during this input event.
SbInputVector position
The (x, y) coordinates of the persistent cursor controlled by this device. The value is 0
if this data is not applicable. For events with type kSbInputEventTypeMove and device_type kSbInputDeviceTypeGamepad, this field is interpreted as a stick position with the range [-1, 1], with positive values for the down and right direction.
SbInputVector delta
The relative motion vector of this input. The value is 0
if this data is not applicable.
float pressure
The normalized pressure of the pointer input in the range of [0,1], where 0 and 1 represent the minimum and maximum pressure the hardware is capable of detecting, respectively. Use NaN for devices that do not report pressure. This value is used for input events with device type mouse or touch screen.
SbInputVector size
The (width, height) of the contact geometry of the pointer. This defines the size of the area under the pointer position. If (NaN, NaN) is specified, the value (0,0) will be used. This value is used for input events with device type mouse or touch screen.
SbInputVector tilt
The (x, y) angle in degrees, in the range of [-90, 90] of the pointer, relative to the z axis. Positive values are for tilt to the right (x), and towards the user (y). Use (NaN, NaN) for devices that do not report tilt. This value is used for input events with device type mouse or touch screen.
const char * input_text
The text to input for events of type Input
.
bool is_composing
Set to true if the input event is part of a composition event.
A 2-dimensional vector used to represent points and motion vectors.
float x
float y
