Member Function Documentation

virtual bool NvInputCallbacks::characterInput ( uint8_t  c  )  [pure virtual]

Character input event Called when a keypressed, release or hold is unhandled and maps to a character param[in] c the ASCII character of the event.

Returns:
true if the recipient handled the event, false if the recipient wishes the caller to handle the event

Implemented in NvSampleApp.

virtual bool NvInputCallbacks::gamepadChanged ( uint32_t  changedPadFlags  )  [pure virtual]

Gamepad input event Called when any button or axis value on any active gamepad changes.

Parameters:
[in] changedPadFlags a mask of the changed pad indices. For each gamepad i that has changed, bit (1<<i) will be set.
Returns:
true if the recipient handled the event, false if the recipient wishes the caller to handle the event

Implemented in NvSampleApp.

virtual bool NvInputCallbacks::keyInput ( uint32_t  code,
NvKeyActionType::Enum  action 
) [pure virtual]

Key input event Called when a key is pressed, released or held param[in] code the keycode of the event.

This is an NvKey mask param[in] action the action for the given key

Returns:
true if the recipient handled the event, false if the recipient wishes the caller to handle the event. Returning true from a key event will generally preclude any characterInput events coming from the action

Implemented in NvSampleApp.

virtual bool NvInputCallbacks::pointerInput ( NvInputDeviceType::Enum  device,
NvPointerActionType::Enum  action,
uint32_t  modifiers,
int32_t  count,
NvPointerEvent points 
) [pure virtual]

Pointer input event.

Called when any pointer device has changed

Parameters:
[in] device the device generating the event
[in] action the action represented by the event
[in] modifiers any modifiers to the event (normally only for mice)
[in] count the number of points in the points array parameter
[in] points an array of the points in the event (normally a single point unless the device is a multi-touch screen
Returns:
true if the recipient handled the event, false if the recipient wishes the caller to handle the event

Implemented in NvSampleApp.
