ミックスインとスタイル

Override the `--hub-signature-*` design tokens in a single include, without coupling the consumer to the component's DOM. Every parameter is OPTIONAL and defaults to `null`: only the parameters you pass are emitted, so the tokens you leave alone keep resolving through their own defaults. An include with no arguments would therefore emit nothing at all, which reads as a broken build rather than as a no-op — so it raises a `@warn` instead of failing silently. Token-based and self-contained (no Bootstrap dependencies).

Sign with the keyboard: arrow keys move the pen, holding Shift moves it further, Space or Enter lowers and lifts it, and Escape discards the stroke in progress.

Signature

Design tokens read by this component. Override them on the host element (or any ancestor) to customize; every default falls back to the ng-hub-ui-ds layer.

Load the forms stylesheet

The chrome around the canvas is not the signature's. Its root element is class="hub-field hub-signature" and the label row, the helper text, the validation feedback and the ? mark that opens it are all defined in ng-hub-ui-forms, so @use 'ng-hub-ui-forms/styles'; belongs in the application's global stylesheet, once. Skip it and the canvas still looks right while the text under it falls back to unstyled body copy and the ? mark, glyph and circle included, is left as an empty button. Add @use 'ng-hub-ui-utils/styles/tooltip'; too when the field uses formTextType="tooltip": the bubble is appended to <body>, out of reach of the sheet above. Neither is replaced by ng-hub-ui-signature/styles, which forwards the theming mixin and emits no chrome.

Match the form theme

The field inherits the forms token family and accepts a local signature token override. Validation is part of that inheritance: the invalid and valid states colour the drawing surface from the shared --hub-form-* contract, so a signature turns red alongside the inputs around it rather than printing a message under a canvas that still looks fine.

フォームのテーマを継承する

フォームを一度整えれば署名フィールドも追随します。描画面は --hub-input-*、ラベルは --hub-label-* を既定値としてたどるため、--hub-signature-* のルールは一つも要りません。非対称な点に注意してください。これらのトークンは var() で継承値から読まれるためラッパーからでも効きますが、--hub-signature-* はフィールド要素自体に宣言されています。
