Module extend 

The helpers HeroGPUI supports for building custom widgets that match the components: v3’s radius scale read from the active theme, the field metrics, the interactive cursor, the focus-visible modality, and the vanilla-GPUI workarounds the components themselves use.

Everything else the components share stays private to this crate, so its signatures can change without a breaking release.

Constants

FIELD_HEIGHT

The one height every v3 form field has: .date-input-group and .color-input-group are h-9, and .input’s py-2 plus its line box comes to the same 36px. v3 removed size from the field components (Input, Select, ComboBox, DateField, …), keeping it only on the nineteen where a scale is documented, so a field’s metrics are constants rather than a herogpui_core::Size lookup.

FIELD_ICON

Glyph size for an icon inside a form field.

FIELD_TEXT

Type size inside a form field.

Functions

app_focus_root

Records keyboard-versus-pointer input, and moves the focus on Tab.

container_radius

min(32px, --radius-3xl) — cards, the table, and every floating panel (modal, popover, toast, alert, dropdown). Surface is not on the list: upstream .surface declares no radius.

control_radius

rounded-3xl — buttons, toggle buttons and avatars.

cursor_interactive

Applies the theme’s interactive cursor (--cursor-interactive) to el.

field_radius

Corner radius of a form field — --field-radius.

focus_visible

Whether focus rings should currently be shown, i.e. the last interaction was keyboard-driven.

hairline_radius

rounded-sm — separators and skeletons, which are nearly square.

inner_fill_radius

Corner radius for a fill painted inside a rounded overflow_hidden clip parent on vanilla GPUI.

interactive_cursor

The theme’s interactive cursor, for a site that must capture it by value.

key_radius

rounded-lg — the keyboard key and the radio control, which v3 draws as a rounded square rather than a circle.

mark_radius

rounded-md — the checkbox control (.checkbox__control is size-4 rounded-md).

micro_radius

rounded-xs — the small ProgressBar track.

set_focus_visible

Sets whether focus rings should be shown, refreshing windows when the value changes.

shift_wheel_scroll_x

Shift+wheel horizontal scroll for mouse wheels on the web platform.

small_radius

rounded-xl — close buttons, tags, links, tooltips.

soft_radius

rounded-2xl — chips, menu and list rows, the colour area.
