In earlier versions of JViews
jvmf:googleView
only worked with Google™ Maps
JavaScript API V2. (For more information about JavaScript API V2,
see http://code.google.com/intl/fr-FR/apis/maps/documentation/javascript/v2/).
In JViews V8.8 or later
jvmf:googleView
works with both Google Maps JavaScript API V2 and V3. (For more
information about JavaScript API V3, see http://code.google.com/intl/fr-FR/apis/maps/documentation/javascript/).
To choose the version of Google Maps JavaScript API,
jvmf:googleView
has a property called
apiVersion
. The default value of this property is
v2
to maintain compatibility with earlier versions. To use V3 of the
API, you can specify
v3
in the
apiVersion
property as shown in the following example:
<jvmf:googleView apiVersion="v3" .... />
When you choose to use Google Maps
JavaScript API V3, you have the ability to show tooltips when you
hover over JViews static map layers as shown in the following
figure.

With Google Maps JavaScript API V2, you must specify a key in
jvmf:googleView
. With V3 (JViews 8.8 or later) this key is no longer necessary.
Note that the controls property has a
different syntax depending on the Google Maps JavaScript API
version that you have chosen.
