Struct rute::auto::line::Line

pub struct Line<'a> { /* private fields */ }

Notice these docs are heavy WIP and not very relevent yet

A QLine describes a finite length line (or a line segment) on a two-dimensional surface. The start and end points of the line are specified using integer point accuracy for coordinates. Use the QLineF constructor to retrieve a floating point copy.

• 

• 

The positions of the line’s start and end points can be retrieved using the p1(), x1(), y1(), p2(), x2(), and y2() functions. The dx() and dy() functions return the horizontal and vertical components of the line. Use isNull() to determine whether the QLine represents a valid line or a null line.

Finally, the line can be translated a given offset using the translate() function.

Implementations

impl<'a> Line<'a>

pub fn new() -> Line<'a>

pub fn is_null(&self) -> bool

Returns true if the line is not set up with valid start and end point; otherwise returns false.

pub fn p1(&self) -> Point<'_>

Returns the line’s start point.

See also: [x1()] [y1()] [p2()]

pub fn p2(&self) -> Point<'_>

Returns the line’s end point.

See also: [x2()] [y2()] [p1()]

pub fn x1(&self) -> i32

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

See also: [p1()]

pub fn y1(&self) -> i32

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

See also: [p1()]

pub fn x2(&self) -> i32

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

See also: [p2()]

pub fn y2(&self) -> i32

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

See also: [p2()]

pub fn dx(&self) -> i32

Returns the horizontal component of the line’s vector.

See also: [dy()]

pub fn dy(&self) -> i32

Returns the vertical component of the line’s vector.

See also: [dx()]

pub fn center(&self) -> Point<'_>

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

pub fn set_p1<P: PointTrait<'a>>(&self, p1: &P) -> &Self

Sets the starting point of this line to p1.

See also: [set_p2()] [p1()]

pub fn set_p2<P: PointTrait<'a>>(&self, p2: &P) -> &Self

Sets the end point of this line to p2.

See also: [set_p1()] [p2()]

pub fn set_points<P: PointTrait<'a>>(&self, p1: &P, p2: &P) -> &Self

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

See also: [set_p1()] [set_p2()] [p1()] [p2()]

pub fn set_line(&self, x1: i32, y1: i32, x2: i32, y2: i32) -> &Self

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

Trait Implementations

impl<'a> Clone for Line<'a>

fn clone(&self) -> Line<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.
