type Composable = api.Composable

func Filled 

func Filled(
	value string,
	onValueChange func(string),
	options ...TextFieldOption,
) Composable

Filled implements the Filled Material Design 3 text field. It uses a custom widget implementation.

func Outlined 

func Outlined(
	value string,
	onValueChange func(string),
	options ...TextFieldOption,
) Composable

Outlined implements the Outlined Material Design 3 text field. It uses a custom widget implementation adapted from gio-x.

func OutlinedSecureTextField

	onValueChange func(string),
	label string,
	options ...TextFieldOption,
) Composable

TextField implements a Material Design 3 text field. It defaults to the Filled variant for backward compatibility, but users should prefer explicit Filled or Outlined calls.

type Composer 

type Composer = api.Composer

type FilledTextFieldWidget 

type FilledTextFieldWidget struct {
	widget.Editor

	Helper string
	Colors TextFieldColors
	Prefix layout.Widget
	Suffix layout.Widget
	// contains filtered or unexported fields
}

FilledTextFieldWidget is the local implementation of the Filled text field.

func (*FilledTextFieldWidget) IsErrored 

func (in *FilledTextFieldWidget) IsErrored() bool

}

type Modifier 

type Modifier = modifier.Modifier

type OnSubmitWrapper 

type OnSubmitWrapper struct {
	Func func()
}

type OutlinedTextFieldWidget 

type OutlinedTextFieldWidget struct {

	Suffix    layout.Widget
	Colors    TextFieldColors
	// contains filtered or unexported fields
}

func (*OutlinedTextFieldWidget) Clear 

func (in *OutlinedTextFieldWidget) Clear()

func (in *OutlinedTextFieldWidget) TextTooLong() bool

TextTooLong returns whether the current editor text exceeds the set character limit.

type Progress 

type Progress struct {
	// contains filtered or unexported fields
}

Progress is an animation primitive that tracks progress of time over a fixed duration as a float between [0, 1].

Progress is reversable.

Widgets map async UI events to state changes: stop, forward, reverse. Widgets then interpolate visual data based on progress value.

Update method must be called every tick to update the progress value.

func (p Progress) Finished() bool

func (Progress) Progress 

func (p Progress) Progress() float32

Progress reports the current progress as a float between [0, 1].

func (*Progress) Start 

func (p *Progress) Start(began time.Time, direction ProgressDirection, duration time.Duration)

Start the progress in the given direction over the given duration.

func (Progress) Started 

func (p Progress) Started() bool

VisibilityAnimation holds the animation state for animations that transition between a "visible" and "invisible" state for a fixed duration of time.

func (VisibilityAnimation) Animating 

func (v VisibilityAnimation) Animating() bool

Animating() returns whether the animation is either in the process of appearsing or disappearing.

func (*VisibilityAnimation) Appear 

func (v *VisibilityAnimation) Appear(now time.Time)

Appear triggers the animation to begin becoming visible at the provided time. It is a no-op if the animation is already visible.

func (*VisibilityAnimation) Disappear 

func (v *VisibilityAnimation) Disappear(now time.Time)

Disappear triggers the animation to begin becoming invisible at the provided time. It is a no-op if the animation is already invisible.

func (*VisibilityAnimation) Revealed 

func (v *VisibilityAnimation) Revealed(gtx layout.Context) float32

Revealed returns the fraction of the animated entity that should be revealed at the current time in the animation. This fraction is computed with linear interpolation.

Revealed should be invoked during every frame that v.Animating() returns true.

If the animation reaches its end this frame, Revealed will transition it to a non-animating state automatically.

If the animation is in the process of animating, calling Revealed will automatically add an InvalidateOp to the provided layout.Context to ensure that the next frame will be generated promptly.

func (*VisibilityAnimation) ToggleVisibility 

func (v *VisibilityAnimation) ToggleVisibility(now time.Time)
