Struct qt_core::FillRule

#[repr(transparent)]pub struct FillRule(_);

Specifies which method should be used to fill the paths and polygons.

C++ enum: Qt::FillRule.

C++ documentation:

Methods

impl FillRule

pub fn to_int(&self) -> c_int

impl FillRule

pub const OddEvenFill: FillRule

Specifies that the region is filled using the odd even fill rule. With this rule, we determine whether a point is inside the shape by using the following method. Draw a horizontal line from the point to a location outside the shape, and count the number of intersections. If the number of intersections is an odd number, the point is inside the shape. This mode is the default. (C++ enum variant: OddEvenFill = 0)

pub const WindingFill: FillRule

Specifies that the region is filled using the non zero winding rule. With this rule, we determine whether a point is inside the shape by using the following method. Draw a horizontal line from the point to a location outside the shape. Determine whether the direction of the line at each intersection point is up or down. The winding number is determined by summing the direction of each intersection. If the number is non zero, the point is inside the shape. This fill mode can also in most cases be considered as the intersection of closed shapes. (C++ enum variant: WindingFill = 1)
