Variables

var BackdropBlur = true

BackdropBlur turns the dialogs' backdrop blur on. Tests turn it off: the CPU renderer the Tester draws with blurs pixel by pixel, which under -race runs every dialog test many times slower.

func DialogShown 

func DialogShown() bool

func Elevate

List is ui.List with the selected rows in the sidebar's selected gray and the foreground, not mygo's accent (the primary, near-black). mygo styles a row from the theme current when it builds it, so the rows' content gets the frame's own theme back. 

func NavSwitch(c *ui.Context, items ...NavItem) ui.Element

NavSwitch is a segmented row of page links on the window material: the page shown raised on the background in the fill icon, the others muted.

func Panel 

func Panel(c *ui.Context, radius float32) ui.Element

func Pressable 

func Pressable(c *ui.Context, o PressableOpts) ui.Element

func Radio 

func Radio[T comparable](c *ui.Context, sel *T, v T, label string) ui.Element

Radio is a radio button choosing v into *sel.

func Resizer 

func Resizer(c *ui.Context, size *float32, gap float32, over bool, label string, onClick func(), first, second func()) (changed, dragging bool)

Resizer is first, *size wide, beside second, with a gap of gap between them that the user drags (or, focused, moves with the arrows) to set *size, as Claude's: hovered, dragged or focused, a GripWidth line of the foreground at 20% shows down the gap's middle, and hovering that names it (label) beside it. It reports whether *size changed, and whether the grip is being dragged; the caller clamps *size. onClick, if any, is what a click on the grip does. With over, the panels touch (they differ enough to need no gap, as a sidebar and the content beside it): the grip, gap wide, rides second's edge (its Hairline border) down the middle, reaching as little into either. Gap is then GripWidth: first's scroll bar keeps further from its edge than the grip reaches, so the grip runs beside it, not over it.

func Select 

func Select[T comparable](c *ui.Context, sel *T, opts []Option[T]) ui.Element

Select is a 32-high select of opts; give it a Label.

func SelectWith

func SidebarItem 

func SidebarItem(c *ui.Context, o SidebarItemOpts) ui.Element

SidebarItem is a row of a page's sidebar, its children left-aligned: 32 high, highlighted while selected or hovered. Give it its Children.

func Skeleton 

func Skeleton(c *ui.Context, w, h float32) ui.Element

Skeleton is a pulsing placeholder w wide (0: the full width) and h high. It stays still under ReduceMotion, which Loop does not honor itself.

func Spinner 

func Spinner(c *ui.Context) ui.Element

Spinner shows that something is under way.

func StatusDot

TextArea is a multi-line text input. 

func TextLink(c *ui.Context, label string, color ui.Color, size float32) ui.Element

TextLink is an underlined text button of size in color (a notice's action).

func ToastHost 

func ToastHost(c *ui.Context, closeLabel string)

ToastHost draws the window's toasts (c.Toast, c.AddToast) centered under the top bar, the oldest first and at most theme.ToastMax; call it once in the view. closeLabel names the close buttons (pass the translated "Close"). A success, warning or error toast is tinted: its color's 50 behind, 200 around, 700 for the text and its leading icon; a plain one is white, without an icon.

func ToggleGroup 

func ToggleGroup(c *ui.Context, label string, fn func()) ui.Element

ToggleGroup groups the buttons fn builds: one Tab stop, the arrow keys move between them.
