public class FileUploader{
private ControlPanel cp;
private FormPanel form = new FormPanel();
private FileUpload fu = new FileUpload();
public FileUploader(ControlPanel cp) {
this.cp = cp;
this.cp.setPrimaryArea(getFileUploaderWidget());
}
@SuppressWarnings("deprecation")
public Widget getFileUploaderWidget() {
form.setEncoding(FormPanel.ENCODING_MULTIPART);
form.setMethod(FormPanel.METHOD_POST);
// form.setAction
(/* WHAT SHOULD I PUT
HERE */);
VerticalPanel holder = new VerticalPanel();
fu.setName("upload");
holder.add(fu);
holder.add(new Button("Submit", new ClickHandler() {
public void onClick(ClickEvent event) {
GWT.log("You selected: " + fu.getFilename(),
null);
form.submit();
}
}));
form.addSubmitHandler(new FormPanel.SubmitHandler() {
public void onSubmit(SubmitEvent event) {
if (!"".equalsIgnoreCase(fu.getFilename())) {
GWT.log("UPLOADING FILE????", null);
