type LinearGradient

type LinearGradient struct {
	StartColor color.Color // The beginning color of the gradient
	EndColor   color.Color // The end color of the gradient
	Angle      float64     // The angle of the gradient (0/180 for vertical; 90/270 for horizontal)

LinearGradient defines a Gradient travelling straight at a given angle. The only supported values for the angle are 0.0 (vertical) and 90.0 (horizontal), currently.

func NewHorizontalGradient

func NewHorizontalGradient(start, end color.Color) *LinearGradient

NewHorizontalGradient creates a new horizontally travelling linear gradient. The start color will be at the left of the gradient and the end color will be at the right.

func NewLinearGradient

func NewLinearGradient(start, end color.Color, angle float64) *LinearGradient

NewLinearGradient creates a linear gradient at a the specified angle. The angle parameter is the degree angle along which the gradient is calculated. A NewHorizontalGradient uses 270 degrees and NewVerticalGradient is 0 degrees.

func NewVerticalGradient

func NewVerticalGradient(start color.Color, end color.Color) *LinearGradient

NewVerticalGradient creates a new vertically travelling linear gradient. The start color will be at the top of the gradient and the end color will be at the bottom.

func (*LinearGradient) Generate

func (g *LinearGradient) Generate(iw, ih int) image.Image

Generate calculates an image of the gradient with the specified width and height.

func (*LinearGradient) Hide

func (r *LinearGradient) Hide()

Hide will set this object to not be visible.

func (*LinearGradient) MinSize

func (r *LinearGradient) MinSize() fyne.Size

MinSize returns the specified minimum size, if set, or {1, 1} otherwise.

func (*LinearGradient) Move

func (r *LinearGradient) Move(pos fyne.Position)

Move the object to a new position, relative to its parent.

func (*LinearGradient) Position

func (r *LinearGradient) Position() fyne.Position

CurrentPosition gets the current position of this canvas object, relative to its parent.

func (*LinearGradient) Refresh

func (g *LinearGradient) Refresh()

Refresh causes this object to be redrawn in it’s current state

func (*LinearGradient) Resize

func (r *LinearGradient) Resize(size fyne.Size)

Resize sets a new size for the canvas object.

func (*LinearGradient) SetMinSize

func (r *LinearGradient) SetMinSize(size fyne.Size)

SetMinSize specifies the smallest size this object should be.

func (*LinearGradient) Show

func (r *LinearGradient) Show()

Show will set this object to be visible.

func (*LinearGradient) Size

func (r *LinearGradient) Size() fyne.Size

CurrentSize returns the current size of this canvas object.

func (*LinearGradient) Visible

func (r *LinearGradient) Visible() bool

IsVisible returns true if this object is visible, false otherwise.
