Types

type Axis

type Axis uint8

Axis defines the direction of a widget with multiple elements

const (
	Horizontal Axis = iota
	Vertical
)

func (Axis) Constraints

func (a Axis) Constraints(mainMin, mainMax, crossMin, crossMax int) constraints.Constraints

Constraints return the Constraints for axis a

func (Axis) Convert

func (a Axis) Convert(pt image.Point) image.Point

Convert a point in (x, y) coordinates to (main, cross) coordinates, or vice versa. Specifically, Convert((x, y)) returns (x, y) unchanged for the horizontal axis, or (y, x) for the vertical axis.

func (Axis) CrossConstraint

func (a Axis) CrossConstraint(cs constraints.Constraints) (int, int)

CrossConstraint returns the min and max cross Constraints for axis a

func (Axis) MainConstraint

func (a Axis) MainConstraint(cs constraints.Constraints) (int, int)

MainConstraint returns the min and max main Constraints for axis a

func (Axis) String

func (a Axis) String() string
