Table 6.213. rich : virtualEarth attributes
Attribute Name | Description |
---|---|
binding | The attribute takes a value-binding expression for a component property of a backing bean |
dashboardSize | Initial map type. The possible values are Normal,Small,Tiny. The default value is Normal |
id | Every component may have a unique id that is automatically created if omitted |
lat | Initial latitude coordinate in degrees, as a number between -90 and +90 |
lng | Initial longitude coordinate in degrees, as a number between -180 and +180 |
mapStyle | Navigation control size. The possible values are Road,Aerial,Hybrid,Birdseye. The default value is Road |
onclick | HTML: a script expression; a pointer button is clicked |
ondblclick | HTML: a script expression; a pointer button is double-clicked |
onkeydown | HTML: a script expression; a key is pressed down |
onkeypress | HTML: a script expression; a key is pressed and released |
onkeyup | HTML: a script expression; a key is released |
onLoadMap | JavaScript code invoked just after the Virtual Earth object is initiated. |
onmousedown | HTML: script expression; a pointer button is pressed down |
onmousemove | HTML: a script expression; a pointer is moved within |
onmouseout | HTML: a script expression; a pointer is moved away |
onmouseover | HTML: a script expression; a pointer is moved onto |
onmouseup | HTML: script expression; a pointer button is released |
rendered | If "false", this component is not rendered |
style | CSS style(s) is/are to be applied when this component is rendered |
styleClass | Corresponds to the HTML class attribute |
var | The JavaScript variable that is used to access the Virtual Earth API. If you have more than one Virtual Earth components on the same page, use individual key for each of them. The default variable name is "map" (without quotes) |
version | Virtual earth version, default - "6" |
zoom | Initial zoom level as a number between 1 and 18. The default value is 17 |
Table 6.214. Component identification parameters
Name | Value |
---|---|
component-type | org.richfaces.VirtualEarth |
component-class | org.richfaces.component.html.HtmlVirtualEarth |
component-family | org.richfaces.VirtualEarth |
renderer-type | org.richfaces.VirtualEarthRenderer |
tag-class | org.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:
"zoom" defines an approximation size (boundary values 1-18)
"lat" specifies an initial latitude coordinate in degrees, as a number between -90 and +90
"lng" specifies an initial longitude coordinate in degrees, as a number between -180 and +180
"dashboardSize" specifies a type of a rendered map (Normal, Small, Tiny)
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.
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.
Table 6.215. Classes names that define a component appearance
Class name | Description |
---|---|
rich-virtualEarth | Defines styles for a wrapper <div> element of a component |
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.
