WxCircleBorder class

A border that fits a circle within the available space.

Typically used with ShapeDecoration to draw a circle.

The dimensions assume that the border is being used in a square space. When applied to a rectangular space, the border paints in the center of the rectangle.

The eccentricity parameter describes how much a circle will deform to fit the rectangle it is a border for. A value of zero implies no deformation (a circle touching at least two sides of the rectangle), a value of one implies full deformation (an oval touching all sides of the rectangle).

See also:

  • OvalBorder, which draws a Circle touching all the edges of the box.
  • WxBorderSide, which is used to describe each side of the box.

Constructors

WxCircleBorder({WxBorderSide? side, Color? color, Gradient? gradient, double? offset, WxBorderStyle? style, double? width, double eccentricity = 0.0})
Create a circle border.
const

Properties

color → Color?
The color of the outline, if specified. Can be overridden by gradient.
finalinherited
dimensions → EdgeInsetsGeometry
The widths of the sides of this border represented as an EdgeInsets.
no setterinherited
eccentricity → double
Defines the ratio (0.0-1.0) from which the border will deform to fit a rectangle. When 0.0, it draws a circle touching at least two sides of the rectangle. When 1.0, it draws an oval touching all sides of the rectangle.
final
effectiveSide → WxBorderSide
Returns the effective WxBorderSide considering any provided overrides.
no setterinherited
gradient → Gradient?
A gradient to use for painting the outline, if provided.
finalinherited
hashCode → int
The hash code for this object.
no setteroverride
offset → double?
An offset to apply to the outline, in logical pixels.
finalinherited
preferPaintInterior → bool
Reports whether paintInterior is implemented.
no setteroverride
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
side → WxBorderSide?
The border outline's color and weight.
finalinherited
style → WxBorderStyle?
The style of the outline (e.g., solid, dashed). Can be overridden by subclasses.
finalinherited
width → double?
The desired width of the outline, in logical pixels.

Methods

add(ShapeBorder other, {bool reversed = false}) → ShapeBorder?
Attempts to create a new object that represents the amalgamation of this border and the other border.
inherited
copyWith({WxBorderSide? side, WxBorderStyle? style, Color? color, Gradient? gradient, double? width, double? offset, double? eccentricity}) → WxCircleBorder
Creates a copy of this WxOutlinedBorder with modified properties.
getInnerPath(Rect rect, {TextDirection? textDirection}) → Path
Create a Path that describes the inner edge of the border.
override
getNonSolidPath(Path source, {TextDirection? textDirection}) → Path
Calculates the path for a non-solid outline style (e.g., dashed).
inherited
getOuterPath(Rect rect, {TextDirection? textDirection}) → Path
Create a Path that describes the outer edge of the border.
override
lerpFrom(ShapeBorder? a, double t) → ShapeBorder?
Linearly interpolates from another ShapeBorder (possibly of another class) to this.
lerpTo(ShapeBorder? b, double t) → ShapeBorder?
Linearly interpolates from this to another ShapeBorder (possibly of another class).
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
paint(Canvas canvas, Rect rect, {TextDirection? textDirection}) → void
Paints the border within the given Rect on the given Canvas.
override
paintInterior(Canvas canvas, Rect rect, Paint paint, {TextDirection? textDirection}) → void
Paint a canvas with the appropriate shape.
override
scale(double t) → ShapeBorder
Creates a copy of this border, scaled by the factor t.
toString() → String
A string representation of this object.
override

Operators

operator +(ShapeBorder other) → ShapeBorder
Creates a new border consisting of the two borders on either side of the operator.
inherited
operator ==(Object other) → bool
The equality operator.
