@ -218,13 +218,15 @@ Gets the mouse-wheel motion delta, when handling mouse-wheel events EVENT_MOUSEW
:param flags: The mouse callback flags parameter.
For regular mice with a scroll-wheel, delta will be a multiple of 120. The value 120 corresponds to a one notch rotation of the wheel or the threshold for action to be taken and one such action should occur for each delta.
Some high-precision mice with higher-resolution freely-rotating wheels may generate smaller values.
For EVENT_MOUSEWHEEL positive and negative values mean forward and backward scrolling, respectively.
For EVENT_MOUSEHWHEEL, where available, positive and negative values mean right and left scrolling, respectively.
.. note::
Mouse-wheel event are currently available only on Windows. On Windows Units are usually multiples of 120.
Mouse-wheel events are currently supported only on Windows.
