Re: Dictionary on demand
Thank you for this sample, very interesting.
Just for information, where do you instanciate DictionaryOnDemand?
In my case, I create it in the onModuleLoad method, because I need it
in view initialization, but the problem is that : because of deffered
command (but needed...), dictionnary is binded after view init
Any idea?
Thank again,

Re: Dictionary on demand
IMPORTANT, THE PREVIOUS NATIVE METHOD IS NOT CORRECT
The nativ method must be
private static native void getJsFile() /*-{
var fileref = $doc.createElement('script');
fileref.setAttribute("type","text/javascript");
fileref.setAttribute("src","operadores/operadores.js");
$doc.getElementsByTagName("head")[0].appendChild(fileref)
}-*/;
just to load correctly the file...

Re: Dictionary on demand
I really don't assume this, it's the way I'm going to use it.
In my application, the file is generated by a servlet that writes a
POJO into the file, as shown
response.setContentType("text/javascript");
response.setHeader("Expires", "0");
response.setHeader("Cache-Control", "must-revalidate, post-
check=0, pre-check=0");
response.setHeader("Pragma", "public");
StringBuilder sb = new StringBuilder();
sb.append("var mypojovar = {");
for (MyPojo myPojo : database.getMyPojoList())
sb.append("\n\t").append(myPojo.getId()).append(":
\"").append(myPojo.getName()).append("\",");
sb.deleteCharAt(sb.length() - 1);
sb.append("\n};");
response.getWriter().print(sb.toString());
response.getOutputStream().flush();
response.getOutputStream().close();
BTW, the mehod is easyly modificable to accetp different file and
variable/dictionary name
public DictionaryOnDemand(String url, String dname){
getJsFile(url);
dictionary = Dictionary.getDictionary(dname);
}
private native void getJsFile(String url) /*- {
var fileref = $doc.createElement('script');
fileref.setAttribute("type","text/javascript");
fileref.setAttribute("src", url);
} -*/;
The key in this behaviour is the 'text/javascript' content type of the
file

Re: Dictionary on demand
Why do you assume every javascript file would have a ".js" extension? Some files could be dynamically generated depending on querystring parameters so we might request ".php" or ".asp" files --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Dictionary on demand
(uf, a lot of time without posting here...)
I've done a class to load a dictionary on demand, by loading a
javascript file dinamicaly.
Contructor uses a String parameter - sname - which will be the
Dictionary name.
The js file must be named like 'sname.js' and contain a varible like
'var sname'
Aside from this, it works as a normal Dictionary
I post it here, so you can comment it (please if you see any improvent
or correction) - or use it if you like and need the code
Oskar
/*java file [DictionaryOnDemand.java ]
*/
package myutils;
import com.google.gwt.i18n.client.Dictionary;
public class DictionaryOnDemand {
private Dictionary dictionary;
public DictionaryOnDemand(String sname){
getJsFile(sname);
dictionary = Dictionary.getDictionary(sname);
}
private native void getJsFile(String sname) /*- {
var filename = sname + ".js";
var fileref = $doc.createElement('script');
fileref.setAttribute("type","text/javascript");
fileref.setAttribute("src", filename);
} -*/;
public java.lang.String get(java.lang.String s){
return dictionary.get(s);
}
public java.util.Set keySet() {
return dictionary.keySet();
}
public java.lang.String toString() {
return dictionary.toString();
}
public java.util.Collection values() {
return dictionary.values();
}
}
/**example of use
/
DictionaryOnDemand dod = new DictionaryOnDemand("example");
Window.alert( dod.get("myExample") );
/*js file of example [example.js]
/
var example = {
myExample:"Hello GWorldT"
};
