Chip

Chip can be an action when bound with OnClick, or a controlled selectable token when constructed with selected and bound with OnChanged.

Chip("Add filter").OnClick(OpenFilterPicker)

Chip(app::images::tag, "Featured", featured)
    .OnChanged([featured](bool selected) {
      featured = selected;
    })

Labels accept strings or StringResource through StringVariant. Icon overloads accept ImageResource, ImageAsset, or VectorAsset.

Controlled selection

Passing bool or State<bool> selects the visual and semantic state for this composition. OnChanged emits the requested next value; the component never mutates the supplied state automatically.

Use Enabled(false) for an unavailable action or selection.

Theme and accessibility

ChipStyle independently controls normal, selected, and disabled fills, labels, borders, icon geometry, padding, minimum height, radius, and indications. Action chips expose button behavior; selectable chips expose their selected state through semantics.

API

• Label constructors: Chip(label) and Chip(label, bool selected).
• Icon constructors: Chip(icon, label) and Chip(icon, label, bool selected).
• Events: .OnClick(function) or .OnChanged(function).
• Theme style: ChipStyle.

Use SegmentedButton for a fixed mutually exclusive set and Checkbox for a conventional binary setting.

Action versus selection

All four constructors are in huxerui, <huxerui/view.h>, and use StringVariant for labels and ImageVariant for icons. The two selection forms take a bool; a State<bool> supplies that bool through conversion. There is no independent multi-selection model: a row of filter chips normally stores a bool per independent filter or a set of selected IDs.

Bind OnClick(void()) for an action and OnChanged(void(bool)) for the selection form. An ignored selection proposal leaves the displayed selection unchanged. Disabling a selected chip keeps its selected value while preventing changes. This is useful when a filter is active but temporarily locked.

ChipStyle fields

Fields	What they control
background, selected_background	Unselected and selected surfaces.
label_style, selected_label	Label typography and selected foreground.
disabled_background, disabled_selected_background, disabled_label, disabled_selected_label	Each disabled state independently.
border, selected_border, disabled_border, disabled_selected_border	Surface outlines; optional selected overrides permit inheritance.
padding, icon_size, icon_spacing, minimum_height	Content and touch layout.
corner_radii, indication, selected_indication	Shape and feedback for each selection state.

Material uses a 32-DIP minimum-height chip treatment; Flat uses a more compact 28-DIP baseline. Theme overrides change presentation only. There is no built-in trailing delete action in these constructors; use a separate action if removing a token is different from selecting it.
