This composable is to be used on the custom components which a Dialog plugin is invoked with. It will bootstrap all the necessary communication of the component with the plugin.

Syntax

import { useDialogPluginComponent } from 'quasar'

setup () {
  const { dialogRef, onDialogHide, onDialogOK, onDialogCancel } = useDialogPluginComponent()

  // dialogRef      - Vue ref to be applied to QDialog
  // onDialogHide   - Function to be used as handler for @hide on QDialog
  // onDialogOK     - Function to call to settle dialog with "ok" outcome
  //                    example: onDialogOK() - no payload
  //                    example: onDialogOK({ /*.../* }) - with payload
  // onDialogCancel - Function to call to settle dialog with "cancel" outcome

  return {
    dialogRef,
    onDialogHide
  }
}

Full example

<template>
  <!-- notice dialogRef here -->
  <q-dialog ref="dialogRef" @hide="onDialogHide">
    <q-card class="q-dialog-plugin">
      <!--
        ...content
        ... use q-card-section for it?
      -->

      <!-- buttons example -->
      <q-card-actions align="right">
        <q-btn color="primary" label="OK" @click="onOKClick" />
        <q-btn color="primary" label="Cancel" @click="onCancelClick" />
      </q-card-actions>
    </q-card>
  </q-dialog>
</template>
