Returns
Operators
explicit operator MouseMotionEvent(in Event)
Converts a general Event to an event of type MouseMotionEvent
public static explicit operator MouseMotionEvent(in Event @event)
Parameters
eventEventThe general Event to convert to an event of type MouseMotionEvent
Returns
Remarks
The Type of the given event must be MouseMotion.
Otherwise, it will lead the method to throw an ArgumentException!

eventwas not MouseMotion
implicit operator Event(in MouseMotionEvent)
Converts an event of type MouseMotionEvent to a general Event
public static implicit operator Event(in MouseMotionEvent @event)
Parameters
eventMouseMotionEventThe event of type MouseMotionEvent to convert to a general Event
