Usage

<template>
  <div id="app">
    <Map>
      <BaseMapControl position="top-right" />
    </Map>

import { Map, BaseMapControl } from "@skymapglobal/map-3d";

export default {
  name: "App",

  components: {
    Map,
    BaseMapControl,
  },
};
</script>

<style>

Create a simple Module example

<template>
  <ModuleContainer>
    <!-- Children modules -->
    <slot />
  </ModuleContainer>
</template>

<script>
import { ModuleMixin } from "@skymapglobal/map-3d";

export default {
  mixins: [ModuleMixin],

  methods: {
    // Init
    onInit() {
      // Use this.map to access Cesium.Viewer instance

      // Use this.onMapEvent(event, callback) or this.onMapEvent(event, entityIdOrEntity, callback) for listening on event
      // Current event support: 'zoomend', 'click', 'dblclick'

      // Use this.onceMapEvent(event, callback), this.onceMapEvent(event, entityIdOrEntity, callback) for listening once

      // Use this.offMapEvent(event, callback) for removing event listener
    },

    // Destroy
    onDestroy() {

    }
  }
};
</script>

Create Draggable Popup Module example

<template>
  <ModuleContainer>
    <DraggablePopup
      v-bind="$attrs"
      :top="top"
      :right="right"
      :title="title"
      :width="width"
      :height="height"
      :visible.sync="popup.visible"
    >
      My Module
    </DraggablePopup>

    <!-- Children modules -->
    <slot />
  </ModuleContainer>
</template>

<script>
import { ModuleMixin, ButtonGroupControl, DraggablePopup } from "@skymapglobal/map-3d";

export default {
  mixins: [ModuleMixin],

  components: {
    DraggablePopup
  },

  props: {
    top: {
      type: Number,
      default: 10
    },

    right: {
      type: Number,
      default: 50
    },

    height: {
      type: String,
      default: "10vh"
    },

    width: {
      type: String,
      default: "30vw"
    },

    title: {
      type: String,
      default: "My Module"
    },

    controlIcon: {
      type: String,
      default: "mdi mdi-information"
    }
  },

  data() {
    return {
      popup: {
        visible: false
      }
    };
  },

  methods: {
    // Init
    onInit() {
      // Use this.map to access Cesium.Viewer instance
      this.addControl(
        ButtonGroupControl.create([
          {
            title: this.title,
            icon: this.controlIcon,
            onClick: () => {
              this.popup.visible = !this.popup.visible;
            }
          }
        ])
      );

API

Map

Props

• accessToken: String - Cesium Ion Token

Events

• map-loaded: (map) => {} - Used for getting map instance in parent component

ModuleMixin

Data

• loaded: Boolean - whether map is loaded

• map: mapboxgl.Map - Mapbox GL instance

• control: mapboxgl.Control - Mapbox GL control instance

• bus: EventBus - internal event bus

Methods

• addControl(control) - add control to map

• removeControl() - remove added control

• getControl() - get added control

• onMapEvent(event: string, callback: ({ lngLat: { lng: number, lat: number } }) => void)

• onMapEvent(event: string, target: String|Object, callback: ({ lngLat: { lng: number, lat: number } }) => void) - target is entity id or entity

• onMapEvent(event: string, callback: ({ lngLat: { lng: number, lat: number } }) => void)

• onMapEvent(event: string, target: String|Object, callback: ({ lngLat: { lng: number, lat: number } }) => void) - target is entity id or entity

• offMapevent(event: string, callback?)

Hooks

• onInit() - fired when map is ready to use

• onDestroy() - fired when module has been destroyed
