This module includes abstractions for handling mouse events.
onMouseMove : (Position -> msg) -> Html.Attribute msg
Custom event listener for mousemove
that returns the mouse Position
.
onMouseDown : (Position -> List String -> msg) -> Html.Attribute msg
Custom event listener for mousedown
that returns the mouse Position
and the classes of the target element that was clicked.
onWheelScroll : (Position -> Basics.Float -> msg) -> Html.Attribute msg
Custom event listener for wheel
that returns the mouse Position
and the scroll amount of the wheel (in pixels).
Mouse position.
asCoordinate : Position -> Coordinate
Mouse position as coordinate record.
{ x : Basics.Float, y : Basics.Float }
Two dimensional vector that can represent a point or direction.
delta : Position -> Position -> Coordinate
Delta/difference vector between two mouse Position
s.
delta (Position { x = 50, y = 10 }) (Position { x = 20, y = -10 }) == { x = -30, y = -20 }
delta (Position { x = 50, y = 10 }) (Position { x = 20, y = -10 }) == { x = -30, y = -20 }
