Component that presents the Google map in the JSF applications.
Presents all the Google map functionality
Highly customizable via attributes
No developers JavaScript writing needed to use on a pages
To use Google Map in your application, generate a key on Google Map official resource . One key could be used for one directory on the server.
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
"mapType"
specifies a type of a rendered map (G_NORMAL_MAP,
G_SATELLITE_MAP (DEFAULT), G_HYBRID_MAP)
For example, the city of Paris is shown after rendering with
the following initial settings:
lat = "48.44"
,
lng = "2.24"
and
zoom = "5"
.
It's also possible to set accessible controls on the map with the help of the attributes:
"showGMapTypeControl" determines whether the controls for a map type definition are switched on
"showGScaleControl" determines whether the controls for scaling are switched on
"showGLargeMapControl" determines whether the control for map scale rendering is rendered
To set the controls as well as to perform other activities (Zoom In/Out etc.) is possible with your JavaScript, i.e. declare a name of a map object in the "gmapVar" attribute and then call the object directly with Google Maps API.
For instance, if you have gmapVar = "map" declared for your component, to zoom in a map you should call map.zoomIn() on an
event. See also an example of
<rich:gmap>
usage on the RichFaces Live Demo.
You do not need to use reRender to perform uptades for the <rich:gmap> component. Use the "gmapVar" attribute and Google Maps native API instead as it's described above.
Moreover, to add e.g. some JavaScript effects, events defined on it are used.
"onmouseover"
"onclick"
"onmouseout"
etc.
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:
...
<f:view contentType="text/html">...</f:view>
...
Table of <rich:gmap> attributes.
