type GutterStyle ¶

type GutterStyle struct {
	LeftWidth  unit.Dp
	RightWidth unit.Dp
	layout.Alignment
}

GutterStyle configures a gutter on either side of a horizontal row of content. Both sides can optionally display a widget atop the gutter space.

func Gutter() GutterStyle

func (g GutterStyle) Layout(gtx layout.Context, left, center, right layout.Widget) layout.Dimensions

type Rounded ¶

type Rounded unit.Dp

Rounded lays out a widget with rounded corners.

func (r Rounded) Layout(gtx layout.Context, w layout.Widget) layout.Dimensions

type Row ¶

type Row struct {
	// Margin between rows.
	Margin VerticalMarginStyle
	// InternalMargin between internal rows.
	// Leave unset if you want to control spacing between RowChild individually.
	InternalMargin VerticalMarginStyle
	// Gutter handles the left-right gutters of the row that provides padding and
	// can contain other widgets.
	Gutter GutterStyle
	// Direction of widgets within this row.
	// Typically, non-local widgets are aligned W, and local widgets aligned E.
	Direction layout.Direction
}

Row lays out a central widget with gutters either side. The central widget can be arbitrarily aligned and gutters can have supplimentary widgets stacked atop them.

func (r Row) Layout(gtx C, w ...RowChild) D

type RowChild ¶

type RowChild struct {
	Left    layout.Widget
	Content layout.Widget
	Right   layout.Widget
	Unified bool
}

RowChild specifies a content widget and two gutter widgets either side. RowChild is used to layout composite rows made up of any number of interal rows.

func ContentRow(w layout.Widget) RowChild

func FullRow(l, w, r layout.Widget) RowChild

func UnifiedRow(w layout.Widget) RowChild

type VerticalMarginStyle ¶

type VerticalMarginStyle struct {
	Size unit.Dp
}

VerticalMarginStyle provides a simple API for insetting a widget equally on its top and bottom edges. Consistently wrapping chat elements in a single VerticalMarginStyle as their outermost layout type will ensure that they are spaced evenly and no part of their content crowds that of the message above and below.

func VerticalMargin() VerticalMarginStyle

func (v VerticalMarginStyle) Layout(gtx layout.Context, w layout.Widget) layout.Dimensions
