Detailed Description
Input handling callback interfaces.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, | |||
| int64_t | timestamp = 0 | |||
| ) | [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.
