Struct nannou::state::mouse::ButtonMap

pub struct ButtonMap<S = DefaultScalar> { /* fields omitted */ }

Stores the state of all mouse buttons.

If the mouse button is down, it stores the position of the mouse when the button was pressed

Methods

impl<S> ButtonMap<S> where     S: BaseFloat,

pub fn new() -> Self

Returns a new button map with all states set to None

pub fn relative_to(self, xy: Point2<S>) -> Self

Returns a copy of the ButtonMap relative to the given Point

pub fn left(&self) -> &ButtonPosition<S>

The state of the left mouse button.

pub fn middle(&self) -> &ButtonPosition<S>

The state of the middle mouse button.

pub fn right(&self) -> &ButtonPosition<S>

The state of the right mouse button.

pub fn press(&mut self, button: Button, xy: Point2<S>)

Sets the Button in the Down position.

pub fn release(&mut self, button: Button)

Set's the Button in the Up position.
