How to access ComputedProperties from <script>?

[wsw70]

The documentation for QInput (v 2.13.3) mentions in the tab ComputedProps the existence of hasError. How can access this property from within my <script setup lang="ts"> section?

I guess this is a computed property (per its name) that I could watch() to trigger actions as soon as it changes to true.

Found it!

This is the Vue3 reference. You need to add a reactive ref="referenceOfThatComponent" and the content is available as referenceOfThatComponent.value.hasError

Also in our docs: https://quasar.dev/start/how-to-use-vue#handling-vue-methods

Vue 3.5+ added useTemplateRef()

Docs could be slightly updated to mention it and point people to the right direction of the new method.
