Look at
http://code.google.com/intl/en/webtoolkit/doc/latest/DevGuideCodingBasicsJSNI.html
But, into GWT, you can define a static variable in one class, it'll
work as expected
There are no 'global variables' in Java, but you can do
/*********** Example 1 ***************/
class MyModule{
// Defines a global var in Js accesible by Java code
public static native void setVaar(String value) /*-{
$wnd.vaar = value;
}-*/;
public static native String setVaar() /*-{
return $wnd.vaar;
}-*/;
public void onModuleLoad(){
setVaar("");
}
}
/*********** Example 2 ***************/
class MyModule{
// Defines a static var in Java accesible by Js code
public static native void initJs() /*-{
$wnd.getVaar = function(){
return @com.google.gwt.examples.MyModule::vaar;
};
}-*/;
public static String vaar = "";
public void onModuleLoad(){
initJs()
}
}
