Usage

type RadialGradient

type RadialGradient struct {
	StartColor color.Color // The beginning color of the gradient
	EndColor   color.Color // The end color of the gradient
	// The offset of the center for generation of the gradient.
	// This is not a DP measure but relates to the width/height.
	// A value of 0.5 would move the center by the half width/height.
	CenterOffsetX, CenterOffsetY float64
}

RadialGradient defines a Gradient travelling radially from a center point outward.

func NewRadialGradient

func NewRadialGradient(start, end color.Color) *RadialGradient

NewRadialGradient creates a new radial gradient.

func (*RadialGradient) Generate

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

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

func (*RadialGradient) Hide

func (r *RadialGradient) Hide()

Hide will set this object to not be visible

func (*RadialGradient) MinSize

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

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

func (*RadialGradient) Move

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

func (*RadialGradient) Position

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

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

func (*RadialGradient) Refresh

func (g *RadialGradient) Refresh()

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

func (*RadialGradient) Resize

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

Resize sets a new size for the rectangle object

func (*RadialGradient) SetMinSize

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

SetMinSize specifies the smallest size this object should be

func (*RadialGradient) Show

func (r *RadialGradient) Show()

Show will set this object to be visible

func (*RadialGradient) Size

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

CurrentSize returns the current size of this rectangle object

func (*RadialGradient) Visible

func (r *RadialGradient) Visible() bool

IsVisible returns true if this object is visible, false otherwise
