Table 6.267. Component identification parameters

NameValue
component-typeorg.richfaces.VirtualEarth
component-class org.richfaces.component.html.HtmlVirtualEarth
component-familyorg.richfaces.VirtualEarth
renderer-typeorg.richfaces.VirtualEarthRenderer
tag-classorg.richfaces.taglib.VirtualEarthTag

To create the simplest variant on a page use the following syntax:

Example:


...
    <rich:virtualEarth lat="..." lng="..."/>
...

Example:

import org.richfaces.component.html.HtmlVirtualEarth;

...
HtmlVirtualEarth myMap = new HtmlVirtualEarth();
...

Here are the main settings of initial rendering performed with a component map that are accessible with the following attributes:

For example, the city of Paris is shown after rendering with the following initial settings: lat = "48.833" , lng = "2.40" and zoom = "11" .


Code for this example is placed below:

Example:


...
    <rich:virtualEarth  style="width:800px;" id="vm" lat="48.833" lng="2.40" 
                                     dashboardSize="Normal"  zoom="11" mapStyle="Hybrid" var="map" />
...

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 map in the "var" attribute and then call the object directly with API Microsoft Virtual Earth map .

For example, to approximate a map for var = "map" declared inside the component, call map.ZoomIn() on an event.

Moreover, to add e.g. some JavaScript effects, events defined on it are used.

  • "onmouseover"

  • "onclick"

  • "onmouseout"

  • etc.

Note

Virtual Earth 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:


...
<f:view contentType="text/html">...</f:view>
...

<rich:virtualEarth> component isn't tied to skin parameters, as there is no additional elements on it, except the ones provided with Virtual Earth map .


In order to redefine styles for all <rich:virtualEarth> components on a page using CSS, it's enough to create class with the same name and define necessary properties in it.

To change styles of particular <rich:virtualEarth> components, define your own style class in the corresponding <rich:virtualEarth> attribute.
