Action button

What you can do

• style is the visible surface: label (required, 1 to 120 characters), a variant preset (primary, secondary, ghost, outline) and a size preset (sm, md, lg); raw siblings background, color, borderColor, fontSize, paddingX, paddingY, radius, and fontWeight win over the preset when set.
• icon names one of six inline SVGs (download, arrow-right, external-link, filter, filter-off, refresh); iconText renders any glyph of up to four characters verbatim and wins over icon; iconPosition is start or end.
• action is discriminated by kind: navigate opens a page id or a literal https:// url (with target _self or _blank); filter applies set values and/or clear params through the same targets scope ladder a filter control uses; exportPage and exportAll request a workbook (format xlsx, or csv for a single page); python runs author-written Python on the panel's Snowflake source on click and delivers its result as a download, a toast, or a page refresh (an omitted result defaults to toast) — it takes the same code, params, and packages as a python block plus an optional confirm prompt, and needs data.sourceId and the python:author capability to author.
• navigate, filter, and python buttons dispatch on click today; exportPage and exportAll buttons validate and render but a click does nothing yet.
• align (start, center, end), offset, and width (auto, full, or a pixel value from 24 to 4096) place the button in its slot; an action-button accepts no onClick, and carries a data block only when its action is python (the Snowflake sourceId the code runs against).

Applies to an action-button panel in view, edit, and Present modes and in static renders; only navigate, filter, and python actions dispatch on click, and an external url shows its host beside the label before it opens. The primary fill normally takes the theme token chart.series.1 (falling back to accent when that token cannot reach 3.0:1 contrast on the panel background), and the label colour is chosen to stay legible on it.
