Struct QLine

#[repr(C)]
pub struct QLine { /* private fields */ }

The QLine class provides a two-dimensional vector using integer precision

Implementations

impl QLine

pub fn p1(&self) -> QPoint

Returns the line’s start point.

impl QLine

pub fn p2(&self) -> QPoint

Returns the line’s end point.

impl QLine

pub fn x1(&self) -> i32

Returns the x-coordinate of the line’s start point.

impl QLine

pub fn x2(&self) -> i32

Returns the x-coordinate of the line’s end point.

impl QLine

pub fn y1(&self) -> i32

Returns the y-coordinate of the line’s start point.

impl QLine

pub fn y2(&self) -> i32

Returns the y-coordinate of the line’s end point.

impl QLine

pub fn center(&self) -> QPoint

Returns the center point of this line. This is equivalent to (p1() + p2()) / 2, except it will never overflow.

impl QLine

pub fn dx(&self) -> i32

Returns the horizontal component of the line’s vector.

impl QLine

pub fn dy(&self) -> i32

Returns the vertical component of the line’s vector.

impl QLine

pub fn is_null(&self) -> bool

Returns true if the line does not have distinct start and end points; otherwise returns false.

impl QLine

pub fn set_p1(&mut self, p1: &QPoint)

Sets the starting point of this line to p1.

impl QLine

pub fn set_p2(&mut self, p1: &QPoint)

Sets the end point of this line to p2.

impl QLine

pub fn set_line(&mut self, x1: i32, y1: i32, x2: i32, y2: i32)

Sets this line to the start in x1, y1 and end in x2, y2.

impl QLine

pub fn set_points(&mut self, p1: &QPoint, p2: &QPoint)

Sets the start point of this line to p1 and the end point of this line to p2.

impl QLine

pub fn to_linef(&self) -> QLineF

Returns this line as a line with floating point accuracy. since Qt 6.4.

impl QLine

pub fn translate(&mut self, offset: &QPoint)

Translates this line by the given offset.

impl QLine

pub fn translated(&self, offset: &QPoint) -> QLine

Returns this line translated by the given offset.

impl QLine

pub fn new(pt1: QPoint, pt2: QPoint) -> Self

Constructs a line object that represents the line between p1 and p2.

Trait Implementations

impl Clone for QLine

fn clone(&self) -> QLine

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QLine

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

Formats the value using the given formatter.

impl Default for QLine

fn default() -> Self

Constructs a null line.

impl Display for QLine

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

Formats the value using the given formatter.

impl ExternType for QLine

type Id = (Q, L, i, n, e)

A type-level representation of the type’s C++ namespace and type name.

type Kind = Trivial

Either cxx::kind::Opaque or cxx::kind::Trivial.

impl From<&QLine> for QLineF

fn from(line: &QLine) -> Self

Construct a QLineF object from the given integer-based line.

impl From<QLineF> for QLine

fn from(value: QLineF) -> Self

Returns an integer-based copy of this line. Note that the returned line’s start and end points are rounded to the nearest integer.

impl PartialEq for QLine

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

Tests for self and other values to be equal, and is used by ==.

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

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