Open the download window by clicking MenuItem

I want to open uploadwindow item from Upload by clicking MenuItem. Is it possible? Another idea is to add an upload element to the MenuBar, but I think this is not possible, right?

Thanks for the help!

Maybe a little javascript can help you:

Upload upload = new Upload();
upload.setImmediate(true); // if you want to start upload after selection
upload.addStyleName("my-upload");
MenuBar menuBar = new MenuBar();
menuBar.addItem("Caption", new Command() {
    private static final long serialVersionUID = 1L;

    @Override
    public void menuSelected(MenuItem selectedItem) {
        JavaScript.getCurrent().execute(
            "document.getElementsByClassName('gwt-FileUpload')[0].click()");
    }
});
addComponent(upload);
addComponent(menuBar);


If you want to hide the download:

.v-slot-my-upload {
    display: none;
}

The simplest utility MenuBar, MenuItem, Window and Upload, the layout is left for you:



    MenuBar menuBar = new MenuBar();
    final Window window = new Window();
    window.setContent(new Upload());
    menuBar.addItem("Caption", new Command()
    {
        @Override
        public void menuSelected(MenuItem selectedItem)
        {
            UI.getCurrent().addWindow(window);
        }
    });
