CnWidgetWrapper

Container shell around a dashboard widget. Provides a header with icon and title, a scrollable content area, and an optional footer with action links. Accepts a styleConfig object for runtime style overrides (background, border, padding). Used internally by CnDashboardPage for all non-tile widgets.

Usage

<!-- Basic wrapper -->
<CnWidgetWrapper title="My Cases" icon-url="/apps/myapp/img/icon.svg">
  <MyCasesChart :data="chartData" />
</CnWidgetWrapper>

<!-- Without header (borderless, flush — for self-contained card widgets) -->
<CnWidgetWrapper :show-title="false" :borderless="true">
  <CnStatsBlock :stats="kpis" />
</CnWidgetWrapper>

<!-- With NC widget object (used by CnDashboardPage internally) -->
<CnWidgetWrapper
  :title="widget.title"
  :icon-url="widget.iconUrl"
  :icon-class="widget.iconClass"
  :buttons="widget.buttons">
  <CnWidgetRenderer :widget="widget" />
</CnWidgetWrapper>

<!-- With custom footer and header actions -->
<CnWidgetWrapper title="Tasks">
  <template #actions>
    <NcButton type="tertiary" @click="refresh">Refresh</NcButton>
  </template>
  <TaskList :items="tasks" />
  <template #footer>
    <a href="/apps/tasks">View all</a>
  </template>
</CnWidgetWrapper>

Props

Prop	Type	Default	Description
title	String	'Widget'	Widget title shown in the header
showTitle	Boolean	true	Whether to render the header bar
chrome	String	'default'	Card chrome variant. 'default' uses the library card chrome; 'nc-dashboard' reproduces the native Nextcloud Dashboard panel exactly (translucent blurred background via --color-main-background-blur + --filter-background-blur, --border-radius-container-large corners, no border/shadow, 16px header with a 20px/700 title and 32px leading icon, content inset 16px). styleConfig overrides still layer on top.
showActions	Boolean	true	Whether the header's overflow action menu (Refresh / Documentation / Request-a-feature + #action-items) renders. Set false for compact surfaces (e.g. a KPI tile) to drop the menu and free header width.
borderless	Boolean	false	Remove border and background — makes the wrapper transparent
flush	Boolean	false	Remove content padding — lets content extend edge-to-edge
iconUrl	String	null	Image URL for the header icon
iconClass	String	null	CSS class for the header icon (e.g. Nextcloud icon class)
titleIconPosition	String	'right'	Position of the title-icon slot in the header: 'left' places it before the title group; 'right' places it after the actions
titleIconColor	String	null	CSS color value applied to the title-icon slot container (e.g. '#e74c3c')
buttons	Array	[]	Footer button links: [{ text, link }]
styleConfig	Object	{}	Runtime style overrides: { backgroundColor?, borderStyle?, borderWidth?, borderColor?, borderRadius?, padding?: { top, right, bottom, left }, headerStyle?: { backgroundColor?, textColor? } }. The optional headerStyle colours the header bar per-widget.
refreshing	Boolean	false	When bound (e.g. :refreshing="loading" around the host's refetch), the Refresh item is disabled and shows a loading spinner for exactly as long as this stays true — so the spinner reflects the real refresh time.

Slots

Slot	Description
default	Widget content rendered in the scrollable body area
actions	Buttons or controls placed in the right side of the header
title-icon	Extra icon element rendered in the header at the position controlled by titleIconPosition (left of title or right of actions)
footer	Custom footer content (replaces the buttons prop rendering)

Built-in Actions menu

CnWidgetWrapper ships with a small overflow … menu in the header — the shared CnActionsMenu — containing up to three actions, all functional without any host wiring when the wrapper is mounted under CnAppRoot:

• Refresh — emits @refresh, then (unless the host listener calls event.preventDefault()) emits on the @nextcloud/event-bus channel cn:widget:refresh with payload { widgetId, title }. Widgets that care subscribe and filter by widgetId.
• Documentation — rendered only when a documentationUrl is supplied. Opens the host-provided link in a new tab (target="_blank", rel="noopener noreferrer"); no JS handler. Apps pass the URL from the widget configuration (:documentation-url="widget.documentationUrl"); customise the wording with documentationLabel.
• Request a feature — emits @request-feature, then (unless suppressed) auto-mounts CnSuggestFeatureModal with app + page + surface=widget:<id> context auto-filled from CnAppRoot injects. The host can override the default by binding @request-feature and calling event.preventDefault() to handle it themselves.

Opt out per-instance with :show-refresh="false" and/or :show-request-feature="false" (the legacy hide-refresh / hide-request-feature aliases also still work for back-compat). When everything is hidden — both built-ins opted out, no documentationUrl, and no #action-items slot content — the overflow menu disappears entirely. To drop the entire actions area in one go — e.g. on a compact KPI tile whose only header affordance is a date chip — set :show-actions="false".

Set :widget-id so the event-bus payload + modal surface tag are stable across renames; otherwise the wrapper falls back to a slugified title.

Opting into Refresh

A widget can opt in to Refresh in one of three ways. Pick whichever fits the widget's existing reactivity model — all three are first-class.

1. Ref-callable refresh() method (canonical)

The cleanest pattern: expose a method, let the host call it through the ref.

<template>
  <CnWidgetWrapper title="Outgoing calls" widget-id="outgoing-calls-daily">
    <CallsChart ref="chart" />
  </CnWidgetWrapper>
</template>

<script>
export default {
  // Inside CallsChart.vue:
  methods: {
    async refresh() {
      this.data = await this.$store.dispatch('callLogs/refetch')
    },
  },
}
</script>

The host listens via the event-bus channel and routes by id (see mode 3 below for the wiring), or the wrapper invokes the method directly when integrated.

2. Reactive refreshTrigger prop

Useful when the widget cannot easily expose a ref (e.g. async-loaded). The host increments a timestamp; the widget watches it.

<template>
  <CnWidgetWrapper title="Outgoing calls" widget-id="outgoing-calls-daily">
    <CallsChart :refresh-trigger="callsRefreshTrigger" />
  </CnWidgetWrapper>
</template>

<script>
import { subscribe } from '@nextcloud/event-bus'
export default {
  data() {
    return { callsRefreshTrigger: 0 }
  },
  mounted() {
    subscribe('cn:widget:refresh', ({ widgetId }) => {
      if (widgetId === 'outgoing-calls-daily') {
        this.callsRefreshTrigger = Date.now()
      }
    })
  },
}
</script>

3. Event-bus subscription (direct)

The widget subscribes itself; no host plumbing needed.

<script>
import { subscribe, unsubscribe } from '@nextcloud/event-bus'
export default {
  props: { widgetId: { type: String, required: true } },
  mounted() {
    this._onRefresh = ({ widgetId }) => {
      if (widgetId === this.widgetId) this.refetch()
    }
    subscribe('cn:widget:refresh', this._onRefresh)
  },
  beforeDestroy() {
    unsubscribe('cn:widget:refresh', this._onRefresh)
  },
  methods: {
    async refetch() { /* ... */ },
  },
}
</script>

Reference (auto-generated)

The tables below are generated from the SFC source via vue-docgen-cli. They reflect what's actually in CnWidgetWrapper.vue and update automatically whenever the component changes.

Props

Name	Type	Required	Default	Description
title	string		() => t('nextcloud-vue', 'Widget')	Widget title
showTitle	boolean		true	Whether to show the header with title
chrome	string		'default'	Chrome variant for the wrapper card. - 'default' — the library's own card chrome (opaque background, 1px border, compact header). - 'nc-dashboard' — matches the native Nextcloud Dashboard panel exactly using the same design tokens: translucent blurred background (--color-main-background-blur + --filter-background-blur), --border-radius-container-large corners, no border/shadow, a 16px header with a 20px/700 title and 32px leading icon, and content inset 16px on the sides + bottom. styleConfig overrides still layer on top so a user can customise any token.
borderless	boolean		false	Remove border and background — makes the wrapper transparent. Useful for widgets that are self-contained cards (e.g. CnStatsBlock).
flush	boolean		false	Remove content padding — allows content to go edge-to-edge. Useful for list-style widgets where items should span the full width.
iconUrl	string		null	Icon URL (image)
iconClass	string		null	Icon CSS class (e.g., Nextcloud icon class)
titleIconPosition	string		'right'	Position of the title-icon slot in the header. 'left' places it before the title; 'right' places it after the actions.
titleIconColor	string		null	CSS color value applied to the title-icon slot container
buttons	array		[]	Footer action buttons: [{ text, link }]
showActions	boolean		true	Whether the header's overflow action menu (Refresh / Documentation / Request-a-feature + any #action-items) renders. Shown by default; set false for compact surfaces — e.g. a KPI tile whose only header affordance is a date chip — to drop the menu and free header width.
styleConfig	{ backgroundColor: string, borderStyle: string, borderWidth: number, borderColor: string, borderRadius: number, padding: { top: number, right: number, bottom: number, left: number } }		\{\}	Style configuration for the wrapper.
hideRefresh	boolean		false	Hide the built-in Refresh item from the overflow action menu. The Refresh item is shown by default — set this when the widget has no refreshable data source (e.g. a static tile). Alias for the inverse :show-refresh="false"; either form opts out.
hideRequestFeature	boolean		false	Hide the built-in Request-a-feature item from the overflow action menu. Shown by default; set when the consuming app has no public issue tracker to link out to. Alias for the inverse :show-request-feature="false"; either form opts out.
showRefresh	boolean		true	Inverse of hideRefresh. Defaults to true so the action renders. Set :show-refresh="false" to hide. Either hideRefresh OR !showRefresh hides the action — the spec scenario in widget-wrapper declares the show-prefixed form as canonical; the hide- flags remain for back-compat.
showRequestFeature	boolean		true	Inverse of hideRequestFeature. Defaults to true so the action renders. Set :show-request-feature="false" to hide it. Either flag hides the action.
documentationUrl	string		''	Documentation link for this widget. When a non-empty URL is set, the overflow menu renders a "Documentation" item that opens the link in a new tab. Host apps supply it from the widget configuration. Empty (the default) hides the item.
documentationLabel	string		() => t('nextcloud-vue', 'Documentation')	Optional pre-translated label for the Documentation action. Defaults to the lib's translation of "Documentation".
widgetId	string		''	Widget id for the built-in default Refresh / Request-a-feature handlers (B2). Forwarded as the surface: "widget:<id>" value on the auto-mounted CnSuggestFeatureModal AND as the widgetId field on the cn:widget:refresh event-bus payload. When unset, the wrapper falls back to a slugified displayTitle, which works but is less stable than an explicit id.
specRef	string		''	Optional specRef forwarded to the auto-mounted CnSuggestFeatureModal so the resulting GitHub issue links to the spec capability this widget belongs to.
refreshing	boolean		false	Whether a refresh is currently in flight. When bound by the host (e.g. :refreshing="loading" around its refetch), the Refresh item is disabled and shows a loading spinner for exactly as long as this stays true — so the spinner reflects the real refresh time.
refreshLabel	string		() => t('nextcloud-vue', 'Refresh')	Optional pre-translated label for the Refresh action. Defaults to the lib's translation of "Refresh" so callers usually don't need to set this.
requestFeatureLabel	string		() => t('nextcloud-vue', 'Request a feature')	Optional pre-translated label for the Request-a-feature action. Defaults to the lib's translation of "Request a feature".
actionsMenuLabel	string		() => t('nextcloud-vue', 'Actions')	Pre-translated aria-label / tooltip for the overflow menu trigger. Defaults to "Actions".
