Usage
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 rectangle object to a new position, relative to its parent / canvas
func (*LinearGradient) Position
func (r *LinearGradient) Position() fyne.Position
CurrentPosition gets the current position of this rectangle object, relative to its parent / canvas
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 rectangle 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 rectangle object
func (*LinearGradient) Visible
func (r *LinearGradient) Visible() bool
IsVisible returns true if this object is visible, false otherwise
