Swipe Action

Overview

VySwipeAction places an action panel behind a foreground row. A leftward drag reveals the panel, a short rightward flick closes it, and a sufficiently long or fast leftward swipe emits commit.

Usage

Both rowWidth and actionWidth are required because the core gesture primitive performs its threshold and translation calculations in pixels.

<script setup lang="ts">
import { ref } from 'vue'
import { VySwipeAction } from '@vyui/kit'

const open = ref(false)
const archived = ref(false)

function archive() {
  archived.value = true
}
</script>

<template>
  <VySwipeAction
    v-if="!archived"
    v-model:open="open"
    :row-width="360"
    :action-width="96"
    @commit="archive"
  >
    <view class="h-16 px-4 justify-center bg-white">
      <text class="font-medium">Quarterly report</text>
      <text class="text-sm text-neutral-500">Swipe left to archive</text>
    </view>

    <template #actions="{ close }">
      <view
        class="w-24 items-center justify-center bg-primary-600"
        accessibility-element="true"
        accessibility-traits="button"
        accessibility-label="Archive quarterly report"
        @tap="archive(); close()"
      >
        <text class="text-white font-medium">Archive</text>
      </view>
    </template>
  </VySwipeAction>
</template>

Handle commit by completing or confirming the action. A committed row animates through the full rowWidth; removing the completed row from its list is the usual pattern.

Delete action

Use the slot's close function after a panel action. This animates the row closed and updates v-model:open.

<script setup lang="ts">
import { ref } from 'vue'
import { VySwipeAction } from '@vyui/kit'

const open = ref(false)
const deleted = ref(false)

function remove() {
  deleted.value = true
}
</script>

<template>
  <VySwipeAction
    v-if="!deleted"
    v-model:open="open"
    :row-width="320"
    :action-width="88"
    @commit="remove"
  >
    <template #default="{ open: isOpen }">
      <view class="h-16 px-4 flex-row items-center justify-between bg-white">
        <text>Draft message</text>
        <text class="text-sm text-neutral-500">{{ isOpen ? 'Actions open' : 'Swipe left' }}</text>
      </view>
    </template>

    <template #actions="{ close }">
      <view
        class="w-[88px] items-center justify-center bg-error-600"
        accessibility-element="true"
        accessibility-traits="button"
        accessibility-label="Delete draft message"
        @tap="remove(); close()"
      >
        <text class="text-white font-medium">Delete</text>
      </view>
    </template>
  </VySwipeAction>
</template>

Multiple actions

The action panel can contain more than one control as long as their combined width matches actionWidth.

<VySwipeAction
  v-model:open="open"
  :row-width="360"
  :action-width="176"
>
  <view class="h-16 px-4 justify-center bg-white">
    <text>Conversation</text>
  </view>

  <template #actions="{ close }">
    <view
      class="w-[88px] items-center justify-center bg-neutral-200"
      accessibility-element="true"
      accessibility-traits="button"
      accessibility-label="Mark conversation unread"
      @tap="markUnread(); close()"
    >
      <text>Unread</text>
    </view>
    <view
      class="w-[88px] items-center justify-center bg-error-600"
      accessibility-element="true"
      accessibility-traits="button"
      accessibility-label="Delete conversation"
      @tap="remove(); close()"
    >
      <text class="text-white">Delete</text>
    </view>
  </template>
</VySwipeAction>

Default open and disabled

Use defaultOpen for uncontrolled initial state. disabled prevents drag interaction.

<VySwipeAction
  :row-width="320"
  :action-width="88"
  default-open
  disabled
>
  <view class="h-16 px-4 justify-center bg-white">
    <text>Locked row</text>
  </view>
  <template #actions>
    <view class="w-[88px] items-center justify-center bg-neutral-200">
      <text>Locked</text>
    </view>
  </template>
</VySwipeAction>

Custom styles

Use class for the root or ui for the foreground and action panel wrappers.

<VySwipeAction
  v-model:open="open"
  :row-width="360"
  :action-width="96"
  class="rounded-xl"
  :ui="{
    content: 'bg-neutral-50',
    actions: 'bg-error-50',
  }"
>
  <view class="h-16 px-4 justify-center">
    <text>Styled row</text>
  </view>
  <template #actions="{ close }">
    <view class="w-24 items-center justify-center" @tap="close">
      <text class="text-error-700">Close</text>
    </view>
  </template>
</VySwipeAction>

Features and behavior

• Bind v-model:open for controlled open state, or use defaultOpen for an uncontrolled initial state.
• The foreground row translates from 0 when closed to -actionWidth when open.
• During a drag, translation is clamped between 0 and -rowWidth, allowing a full-swipe commit beyond the visible action panel.
• The default and actions slots both receive the resolved open state and a close() function.
• External changes to open animate the row to its open or closed position.
• disabled ignores touch start, so the current state remains unchanged.
• Vertical intent is yielded to a surrounding list after the gesture direction is resolved.

Gesture behavior

The gesture stays undecided for the first 8px. It then claims drags within the horizontal 45° cone and yields predominantly vertical drags for the rest of that touch.

Only the open threshold is exposed by VySwipeAction. The core primitive also has commitThreshold, commitVelocity, velocityThreshold, and duration props, but the current kit wrapper does not forward them.

Props

Keep threshold between 0 and 1. Widths must match the rendered layout; stale or approximate values produce incorrect snap and commit points.

Emits

commit describes the gesture; it does not delete, archive, or otherwise mutate application data for you.

Slots

Styling and theming

Override globally through appConfig.ui.swipeAction or locally with ui.

The side variant sets justify-start or justify-end on actions. The default theme is light-mode-oriented: the foreground is white and the action wrapper uses neutral-100.

Accessibility

VySwipeAction does not currently add native button, adjustable, group, expanded-state, or gesture instructions to the row. Swipe gestures also have no direct keyboard or switch-control equivalent. Every action in the actions slot should therefore be an independently labeled native control, and any destructive full-swipe behavior should have a visible, non-gesture alternative.

The examples add Lynx accessibility-element, accessibility-traits, and accessibility-label attributes to tappable action views. Also expose the same operation elsewhere when a row can be committed by swiping, and consider confirmation or undo for destructive actions.

Platform notes

• Touch tracking, axis locking, velocity calculation, clamping, and release animation run on the Lynx main thread.
• The component is designed for rows inside vertical native lists; predominantly vertical gestures are released without moving or snapping the row.
• There is no automatic measurement. Recalculate and pass rowWidth and actionWidth when layout width changes.
• Only a trailing right-edge panel and leftward reveal gesture are implemented today. RTL and leading-edge reveal are not exposed.
• A full-swipe commit should update or remove the affected row promptly so the completed translation does not leave stale content on screen.

Related components

• Swiper for paging between full content panels.
• ActionSheet for presenting a temporary list of actions.
• DropdownMenu for actions opened by an explicit trigger.
