ToggleButton

JSON-safe ToggleButton props forwarded to Astryx.

Supported Astryx props include:

• label (string; required): Accessible label for the button. Used as visible text, or as aria-label for icon-only buttons.
• isPressed (boolean): Whether the button is currently pressed. Ignored when inside a group.
• onPressedChange ((isPressed: boolean, event: MouseEvent) => void): Called when pressed state should change. Receives the next state and the click event; call event.preventDefault() to skip pressedChangeAction. Ignored when inside a group.
• pressedChangeAction ((isPressed: boolean) => void or Promise<void>): Action handler for API- or navigation-backed toggles, run in a transition. Shows an optimistic pressed state immediately and a spinner while pending; the button stays interruptible by re-clicks.
• size ('sm' or 'md' or 'lg'): Button size. Defaults to group size when inside a group.
• isDisabled (boolean): Whether the button is disabled.
• isLoading (boolean): Whether the button shows a loading spinner.
• icon (ReactNode): Icon element. When provided without children, button becomes icon-only with tooltip from label.
• isIconOnly (boolean): When true, renders as a square icon-only button with 'label' as the aria-label and an automatic tooltip from the label.
• pressedIcon (ReactNode): Icon shown when pressed. Falls back to icon if not provided.
• children (ReactNode): Visible content. If omitted with icon, button becomes icon-only.
• tooltip (string): Tooltip text shown on hover.
• value (string): Value identifier when used inside ToggleButtonGroup. Required in groups.
• data-testid (string): Test selector for automated testing frameworks.

Props typed as React nodes, render functions, event handlers, refs, or StyleX styles are documented for Astryx parity but cannot be serialized directly from Python unless the wrapper adapts them.
