Vaadin create modal Dialog window

java, user-interface, vaadin, window

Solution

This depends which is your main class. From a normal UI-inherited class you can just use addWindow(...) to add a dialog(subwindow) to the UI.

public class MyApplication extends UI
{

    @Override
    protected void init(VaadinRequest request) 
    {
        addWindow(new ModalWindow());
    }
}

Problem

How can I create a modal dialog window in Vaadin 7.x? I've already found out that I have the main window and add to this my new dialog window, but how can I get the main window? I want to reach it from a View. ``` getApplication().getMainWindow() getWindow() ``` none of them works..
