Plugin usage ​

This component is part of the MapControls plugin. If not installed globally, you need to import and use the plugin in your main.ts or use the explicit component import (see section below).

Import and use the MapControls plugin
ts
import { createApp } from "vue";
import App from "./App.vue";

import {

  Map,
  Layers,
  Sources,
  MapControls,
} from "vue3-openlayers";

const app = createApp(App);
// ...
app.use(MapControls); 
// ...

Explicit import ​

If you don't want to install a plugin, you can import the component explicitly. It's available as a child of the named export MapControls.

NOTE

The following documentation refers to the plugin usage. Please make sure to adopt the component names, when you decided to use explicit component imports (e. g. <ol-map> becomes <Map.OlMap> etc.).

You have access to all Methods from the underlying source. Check out the official OpenLayers docs to see the available methods.

To access the source, you can use a ref() as shown below:

vue
<template>
  <!-- ... -->
  <ol-overviewmap-control :ref="controlRef">
    <!-- ... -->
  </ol-overviewmap-control>
  <!-- ... -->
</template>

<script setup lang="ts">
import { ref, onMounted } from "vue";
import type OverviewMap from "ol/control/OverviewMap";

const controlRef = ref<{ control: OverviewMap }>(null);

onMounted(() => {
  const controlRef: OverviewMap = sourceRef.value?.control;
  // call your method on `control`
});
</script>
