A <code>gmaps</code> is a maps component that wraps the famous Google Maps service that you can control it and embedded it in your ZK web application page in pure Java. Inside the <code>gmap</code>, you can manipulate your maps and add contents to the maps to create convenient locality related web application. You can add <code>ginfo</code> to represent an anchored information window for the maps. You can add multiple <code>gmarker</code>s to indicate a special location. You can add <code>gpolyline</code> and <code>gpolygon</code> to indicate a path or an area. You can also overlay <code>gimage</code> and <code>gscreen</code> to indicate very special places.

Since 2016 an [https://developers.google.com/maps/faq#keysystem API Key is mandatory] in order to use the gmaps API.

The APIKey is defined as a global JS variable as in the examples below. Also check out the [[#Trouble Shooting|trouble shooting]] section.
 +
'''NOTE''': You'll have to upgrade to version '''3.0.4''' (older versions don't work anymore)

Gmaps

Gmaps

Check our Maven repository for the latest version.

Employment/Purpose

Components: gmaps, ginfo, gmarker, gpolyline, gpolygon, gimage, and gscreen.

A gmaps is a maps component that wraps the famous Google Maps service that you can control it and embedded it in your ZK web application page in pure Java. Inside the gmap, you can manipulate your maps and add contents to the maps to create convenient locality related web application. You can add ginfo to represent an anchored information window for the maps. You can add multiple gmarkers to indicate a special location. You can add gpolyline and gpolygon to indicate a path or an area. You can also overlay gimage and gscreen to indicate very special places.

Authentication

Configure in Application Scope

Since 4.0.0

In zk.xml 

<library-property>
    <name>org.zkoss.gmaps.apiKey</name>
    <value>your_key</value>
</library-property>
<library-property>
    <name>org.zkoss.gmaps.clientId</name>
    <value>your_client_id</value>
</library-property>

API Key

Important: Since 2016 an API Key is mandatory in order to use the gmaps API. The APIKey is defined as a global JS variable as in the examples below. Also check out the trouble shooting section. NOTE: You'll have to upgrade to version 3.0.4 (older versions don't work anymore)

See Example below.

Client ID

You can specify a client-id at client attribute: 

<gmaps client="YOUR_CLIENT_ID"/>

Example

ZKComRef Gmaps Example.png 


 <window title="Gmaps Demo" border="normal" width="520px">
	<script type="text/javascript" content="zk.googleAPIkey='Your-Google-API-Key';"/>

	<!-- you may wish to specify the version of google map API manually for some reason, 
		use version="[version]" to do it.
		ex: <gmaps version="3.25" id="mymap" ... /> -->
	<gmaps id="mymap" width="500px" height="300px" showSmallCtrl="true">
		<ginfo id="myinfo" open="true">
			<![CDATA[
				Hello, <a href="http://www.zkoss.org">ZK</a>.
			]]>
		</ginfo>
		
		<gmarker id="mymark" lat="37.4410" lng="-122.1490">
			<![CDATA[
				Hello, <a href="http://www.zkoss.org">ZK</a> on top of Gmarker.
			]]>
		</gmarker>
		
		<attribute name="onMapClick">
			Gmarker gmarker = event.getGmarker();
			if (gmarker != null) {
				gmarker.setOpen(true);
			}
		</attribute>
	</gmaps>
 </window>

Properties

Protocol

Since 3.0.0

Specify which protocol to load the Maps API. Currently it supports http for insecure connections and https for secure connections.

Supported Events

Name
Event Type
onSelect
 Event: SelectEvent

Notifies one that the user has selected a new item(can be Ginfo, Gpolyline, or Gpolygon) in the gmaps.

onInfoChange
 Event: InfoChangeEvent

Notifies that the current open information window has changed(opened/closed)

onMapDrop
 Event: MapDropEvent

Notifies that some component is dragged and dropped on the gmaps or gmarker component with latitude and longitude information.

onMapClick

onMapRightClick

onMapDoubleClick

Event: MapMouseEvent

Notifies that some mouse action has been applied on the gmaps or gmarker component with latitude and longitude information.

onMapMove
 Event: MapMoveEvent

Notifies that the view center (latitude, longitude) of the gmaps has been moved.

onMapTypeChange
 Event: MapTypeChangeEvent

Notifies that the map type of the gmaps has been changed.

onMapZoom
 Event: MapZoomEvent

Notifies that the zoom level of the gmaps has been changed.

Work with MVVM

3.0.4 already includes the addon.xml below, you don't need to add it manually.


Since 6.0.0

For work with ZK6 MVVM, it is required to create an addon xml and add the server annotation as follows:


( You can download the sample project [here] )
