    <title>Details of Usage</title>
    <para>To use <emphasis>
        <property>Google Map</property>
      </emphasis> in your application, generate a key on <ulink url="http://google.com/apis/maps"
        >Google Map official resource</ulink>. One key could be used for one directory on the
      server.</para>
    <para>Here are the main settings of initial rendering performed with a component
      <property>map</property> that are accessible with the following attributes:</para>
    <itemizedlist>
      <listitem><para>
        <emphasis>
          <property>&quot;zoom&quot;</property>
        </emphasis> defines an approximation size (boundary values 1-18) </para></listitem>
      <listitem><para>
        <emphasis>
          <property>&quot;lat&quot;</property>
        </emphasis> specifies an initial latitude coordinate in degrees, as a number between -90 and
        +90 </para></listitem>
      <listitem><para>
        <emphasis>
          <property>&quot;lng&quot;</property>
        </emphasis> specifies an initial longitude coordinate in degrees, as a number between -180
        and +180 </para></listitem>
      <listitem><para>
        <emphasis>
          <property>&quot;mapType&quot;</property>
        </emphasis> specifies a type of a rendered map (G_NORMAL_MAP, G_SATELLITE_MAP (DEFAULT),
        G_HYBRID_MAP) </para></listitem>
    </itemizedlist>
    <para>For example, the city of Paris is shown after rendering with the following initial
      settings: <emphasis>
        <property>&quot;lat&quot;</property>
      </emphasis>= 48.44, <emphasis>
        <property>&quot;lng&quot;</property>
      </emphasis>= 2.24 and <emphasis>
        <property>&quot;zoom&quot;</property>
      </emphasis>= 5.</para>

      </mediaobject>
    </figure>
    <para> It&apos;s also possible to set accessible controls on the <property>map</property>
      with the help of the attributes:</para>
    <itemizedlist>
      <listitem><para>
        <emphasis>
          <property>&quot;showGMapTypeControl&quot;</property>
        </emphasis> determines whether the controls for a map type definition are switched on </para></listitem>
      <listitem><para>
        <emphasis>
          <property>&quot;showGScaleControl&quot;</property>
        </emphasis> determines whether the controls for scaling are switched on </para></listitem>
      <listitem><para>
        <emphasis>
          <property>&quot;showGLargeMapControl&quot;</property>
        </emphasis> determines whether the control for <property>map</property> scale rendering is
        rendered </para></listitem>
    </itemizedlist>
    <figure>
      <title><emphasis role="bold"><property>&lt;rich:gmap&gt;</property></emphasis> accessible controls</title>
      <mediaobject>
        <imageobject>
          <imagedata fileref="images/gmap3.png"/>
        </imageobject>
      </mediaobject>
    </figure>
    <para>To set all these parameters and perform some activity (Zoom In/Out etc.) is possible with
      your JavaScript, i.e. declare a name of an object on a <property>map</property> in the <emphasis>
        <property>&quot;gmapVar&quot;</property>
      </emphasis> attribute and then call the object directly with API <emphasis><property>Google
          Map</property>.</emphasis></para>
    <para>For example, to approximate a map for <emphasis>
        <property>&quot;gmapVar&quot;</property>
      </emphasis>= <property>&quot;map&quot;</property> declared inside the component, call
      map.zoomIn() on an event.</para>
    <para>Moreover, to add e.g. some JavaScript effects, events defined on it are used.</para>
    <itemizedlist>
      <listitem><para> onmouseover </para></listitem>
      <listitem><para> onclick </para></listitem>
      <listitem><para> onmouseout </para></listitem>
      <listitem><para> etc. </para></listitem>
    </itemizedlist>

      <para>
        Google Map does not support XHTML format of the page. 
        Thus, if you use Facelets and JSF 1.2, do not forget to put the following tags somewhere on the page:
      </para>
        <programlisting role="XML"><![CDATA[...

    <para>In order to redefine styles for all <emphasis role="bold">
      <property>&lt;rich:gmap&gt;</property>
    </emphasis> components on a page using CSS, it&apos;s enough to create classes with the

    <para>Also it’s possible to change styles of particular <emphasis role="bold"
      ><property>&lt;rich:gmap&gt;</property></emphasis> component. In this case you should create own style classes and use them in corresponding <emphasis role="bold"
        ><property>&lt;rich:gmap&gt;</property></emphasis> <property>styleClass</property> attributes. An example is placed below:</para>
