Struct fermium::events::SDL_MouseWheelEvent

#[repr(C)]
pub struct SDL_MouseWheelEvent {
    pub type_: SDL_EventType,
    pub timestamp: u32,
    pub windowID: u32,
    pub which: u32,
    pub x: i32,

    pub direction: SDL_MouseWheelDirection,
}

Mouse wheel event structure (event.wheel.*)

Fields

type_: SDL_EventType

Should always be SDL_MOUSEWHEEL

timestamp: u32

In milliseconds, populated using SDL_GetTicks.

windowID: u32

The window with mouse focus, if any.

which: u32

The mouse instance id, or SDL_TOUCH_MOUSEID.

x: i32

The amount scrolled horizontally, positive to the right and negative to the left

y: i32

The amount scrolled vertically, positive away from the user and negative toward the user

direction: SDL_MouseWheelDirection

SDL_MOUSEWHEEL_NORMAL or SDL_MOUSEWHEEL_FLIPPED.

When SDL_MOUSEWHEEL_FLIPPED, the values in X and Y will be opposite. Multiply by -1 to change them back.

Trait Implementations

impl Clone for SDL_MouseWheelEvent

fn clone(&self) -> SDL_MouseWheelEvent

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SDL_MouseWheelEvent

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

Formats the value using the given formatter.

impl Default for SDL_MouseWheelEvent

fn default() -> SDL_MouseWheelEvent

Returns the “default value” for a type.

impl Hash for SDL_MouseWheelEvent

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for SDL_MouseWheelEvent

fn cmp(&self, other: &SDL_MouseWheelEvent) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<SDL_MouseWheelEvent> for SDL_MouseWheelEvent

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<SDL_MouseWheelEvent> for SDL_MouseWheelEvent

fn partial_cmp(&self, other: &SDL_MouseWheelEvent) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
