Class Wheel

Definition

Namespace:: Tizen.NUI

Assembly:: Tizen.NUI.dll

API Level:: 3

The wheel event structure is used to store a wheel rolling, it facilitates processing of the wheel rolling and passing to other libraries like Toolkit.
There is a key modifier which relates to keys like Alt, Shift, and Ctrl functions are supplied to check if they have been pressed when the wheel is being rolled.
We support a mouse device and there may be another custom device that support the wheel event. The device type is specified as \e type.
The mouse wheel event can be sent to the specific actor but the custom wheel event will be sent to the window.
