Instance Method Detail

def delta : Float32 #

Wheel offset (positive is up/left, negative is down/right). High-precision mice may use non-integral offsets.


[View source]
def delta=(delta : Number) #

def dup : MouseWheelScrollEvent #
Description copied from struct Value

Returns a shallow copy of this object.

Because Value is a value type, this method returns self, which already involves a shallow copy of this object because value types are passed by value.
