Describes the state of a pointer device

Note: while we support the various different axes that a tablet device might support, presently glutin does not provide this information to us, so these values are currently always set to ‘None’.

Fields

location_in_window: (f64, f64)

The x and y coordinates of the pointer’s location in the window

location_in_canvas: Option<(f64, f64)>

If the view is displaying scaled content, this is the location of the pointer in the coordinate scheme of that content

buttons: Vec<Button>

The buttons that are currently pressed down

pressure: Option<f64>

If the pointer device supports pressure, the pressure the user is applying (from 0.0 to 1.0)

tilt: Option<(f64, f64)>

tilt in degrees relative to the normal to the surface of the screen along the X and Y axes (values from -90 to 90)

rotation: Option<f64>

If the device supports detecting rotation around its own axis, this is amount of rotation in degrees (values from -180 to 180)

flow_rate: Option<f64>

If the device has a ‘flow rate’ adjustment (emulating an airbrush, for example) this is the value of that (from 0.0 to 1.0).

Implementations

impl PointerState

pub fn new() -> PointerState

Creates a pointer state in the default state

Trait Implementations

impl Clone for PointerState

fn clone(&self) -> PointerState

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PointerState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<PointerState> for PointerState

fn eq(&self, other: &PointerState) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &PointerState) -> bool

This method tests for !=.
