Hi olivier,
The code i have written as follows :
public void onModuleLoad()
{
try{ exportStaticMethod(this); }catch(Exception re){
MessageBox.alert(re.getMessage());
}
}
public native void exportStaticMethod(PMGWTHtmlUtils pmGWTHtmlUtils)
/*-{
$wnd.invokeGWT = function(bId,cId,mId,mName,cName)
{
[EMAIL
PROTECTED]::invokeGWT(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;)(bId,cId,mId,mName,cName);
};
if($wnd.callGWTUtils){
$wnd.callGWTUtils();
}
}-*/;
public void invokeGWT( String bId,String cId,String mId,String mName,String
cName ) throws RequestException {
System.out.println( " xxxxxxxxxxxxxxxxxxxxxxxxxxxx :"+ bId);
}
in javascript :
function callGWTUtils( bttnId )
{
alert('xxxxxxxxxxx'+ bttnId);
invokeGWT(
bttnId,"vvvvvvvvvvvvvvvv","vvvvvvvvvvvvvvvv","vvvvvvvvvvvvvvvv","vvvvvvvvvvvvvvvv"
);
/*if( currDispId != null ){
invokeGWT( bttnId,currDispId );
}*/
}
