Functions

func Button 

func Button(label string, onClick func()) *primitives.BoxWidget

func ButtonDisabled 

func ButtonDisabled(label string, disabled bool, onClick func()) *primitives.BoxWidget

func ButtonDisabledFn 

func ButtonDisabledFn(label string, disabled func() bool, onClick func()) *primitives.BoxWidget

func Checkbox 

func Checkbox(opts ...checkbox.Option) *checkbox.Widget

func ContextMenuItem added in v0.6.0 

func ContextMenuItem(label string, onClick func()) *primitives.BoxWidget

ContextMenuItem keeps the standard button interaction behavior while using the flat, compact appearance of an action in a context menu.

func DrawIconButton 

func DrawIconButton(canvas widget.Canvas, bounds geometry.Rect, kind IconButtonKind, hovered, disabled bool)

func DrawLabel added in v0.11.0 

func DrawLabel(canvas widget.Canvas, content string, bounds geometry.Rect, align widget.TextAlign)

DrawLabel renders the semantic label style on a canvas.

func DrawRotatedText added in v0.6.0 

func DrawRotatedText(canvas widget.Canvas, text string, bounds geometry.Rect, size float32, textColor widget.Color, bold bool, rotation TextRotation)

DrawRotatedText draws centered text at a right-angle rotation. Horizontal text continues through DrawText so it retains the canvas's native shaping.

func DrawText 

func DrawText(canvas widget.Canvas, text string, bounds geometry.Rect, size float32, color widget.Color, bold bool, align widget.TextAlign)

func DrawVerticalGradient added in v0.6.0 

func DrawVerticalGradient(canvas widget.Canvas, bounds geometry.Rect, top, bottom widget.Color)

DrawVerticalGradient draws a continuous top-to-bottom gradient as one image. The image rasterizes itself at the display's physical scale, avoiding seams between logical rows at fractional scaling factors.

func DrawVerticalGradientWithBottomBorder added in v0.6.0 

func DrawVerticalGradientWithBottomBorder(canvas widget.Canvas, bounds geometry.Rect, top, bottom, border widget.Color, borderHeight float32)

DrawVerticalGradientWithBottomBorder draws the gradient and its bottom border in one image so fractional scaling cannot introduce a seam between them.

func IconButton 

func IconButton(kind IconButtonKind, onClick func()) *primitives.BoxWidget

func IconButtonDisabled 

func IconButtonDisabled(kind IconButtonKind, disabled bool, onClick func()) *primitives.BoxWidget

func Label added in v0.11.0 

func Label(content string) *primitives.TextWidget

func LargeButton 

func LargeButton(label string, onClick func()) *primitives.BoxWidget

func LargeButtonDisabled 

func LargeButtonDisabled(label string, disabled bool, onClick func()) *primitives.BoxWidget

func MeasureText 

func MeasureText(canvas widget.Canvas, text string, size float32, bold bool) float32

func Radio 

func Radio(opts ...radio.GroupOption) *radio.Group

func SelectListRow 

func SelectListRow(label string, enabled bool, height float32) widget.Widget

func Slider 

func Slider(opts ...slider.Option) *slider.Widget

func Table 

func Table(rows []TableRow, opts ...TableOption) widget.Widget

func Text 

func Text(content string) *primitives.TextWidget

func TextField 

func TextField(value string, inputType textfield.InputType, onChange func(string), onSubmit func(string), extra ...textfield.Option) *textfield.Widget

func Title 

func Title(content string) *primitives.TextWidget
