Problem with creating Window

General
1

I got a problem with change Main Window in my application.
I want to by pressing button show/order/search change main window in my application. I managed to change it after log in / log out, but right now i don’t know what put into listener.
I know line: setMainWindow / removeWindow but it didn’t work while I where trying.
Here are my codes:
Main APP

package com.example.Main;

import com.example.GUI.LoginWindow;
import com.example.GUI.OrderGUI;
import com.example.GUI.SearchGUI;
import com.example.GUI.ShowGUI;

import com.example.GUI.TimelineWindow;
import com.vaadin.Application.UserChangeListener;
import com.vaadin.Application;
import com.vaadin.ui.*;

public class Main extends Application implements UserChangeListener{
	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	
	private Window loginWindow;
	private Window timelineWindow;
	private Window orderGUI;
	private Window showGUI;
	private Window searchGUI;

	public void init() {
		loginWindow = new LoginWindow();
		timelineWindow = new TimelineWindow();
		orderGUI = new OrderGUI();
		showGUI = new ShowGUI();
		searchGUI = new SearchGUI();
		setMainWindow(loginWindow);
		addListener(this);
		addListener((UserChangeListener) timelineWindow);
//		addListener((UserChangeListener) showGUI);
//		addListener((UserChangeListener) orderGUI);
//		addListener((UserChangeListener) searchGUI);
		setTheme("zamowtest1theme");
	}
	public void applicationUserChanged(UserChangeEvent event) {
		if (event.getNewUser() == null) {
			setMainWindow(loginWindow);
			removeWindow(timelineWindow);
			loginWindow.showNotification("Wylogowany");
			} else if (event.getNewUser() != null) {
		setMainWindow(timelineWindow);
		removeWindow(loginWindow);
		timelineWindow.showNotification("Rozpoznany ! :D");
		}
		
}
}

Login:


package com.example.GUI;


import com.vaadin.ui.Button;
import com.vaadin.ui.Button.ClickEvent;
import com.vaadin.ui.FormLayout;
import com.vaadin.ui.PasswordField;
import com.vaadin.ui.TextField;
import com.vaadin.ui.Window;
public class LoginWindow extends Window {
	/**
	 * 
	 */
	private static final long serialVersionUID = -5754380487286999619L;
	private TextField loginField;
	private PasswordField passwordField;
	private Button submitButton;
	public LoginWindow() {
	loginField = new TextField("Login", "TwójLogin");
	passwordField = new PasswordField("Password");
	submitButton = new Button("Submit");
	submitButton.addListener(ClickEvent.class, this, "authenticate");
	setCaption("Logowanie");
	FormLayout formLayout = new FormLayout();
	formLayout.setMargin(true);
	formLayout.addComponent(loginField);
	formLayout.addComponent(passwordField);
	formLayout.addComponent(submitButton);
	addComponent(formLayout);
	}
	public void authenticate(ClickEvent event) {
		String login = (String) loginField.getValue();
		if ("lisu".equals(login)) {
		getApplication().setUser(login);
		} else {
		showNotification("Brak autoryzacji!");
		}
	}
}

Main Window mode:

public class TimelineWindow extends Window implements UserChangeListener{
	
/**

	gridLayout_2.addComponent(label_1, 0, 0);
	gridLayout_2.setComponentAlignment(label_1, new Alignment(48));
	
	
	
	
	
	HorizontalLayout horizontalLayout_2 = new HorizontalLayout();

public void logout() {
getApplication().setUser(null);
}
public void search(){
	
	
//	SearchGUI searchGUI = new SearchGUI();

//	OrderGUI orderGUI = new OrderGUI();

//	ShowGUI showGUI = new ShowGUI();


	
}
public void applicationUserChanged(UserChangeEvent event) {
	// TODO Auto-generated method stub
	label_2.setValue(event.getNewUser());
}
}

One of other Window mode:


package com.example.GUI;

import com.vaadin.ui.AbsoluteLayout;
import com.vaadin.ui.Button;
import com.vaadin.ui.HorizontalLayout;
import com.vaadin.ui.Table;
import com.vaadin.ui.Window;

public class ShowGUI extends Window {
	private AbsoluteLayout mainLayout;
	
	private HorizontalLayout horizontalLayout_2;
	
	private Button button_2;
	
	private Table table_1;
	
	public ShowGUI(){
	mainLayout = new AbsoluteLayout();
	mainLayout.setImmediate(false);
	mainLayout.setWidth("500px");
	mainLayout.setHeight("400px");
	mainLayout.setMargin(false);
	
	// top-level component properties
	setWidth("500px");
	setHeight("400px");
	
	// horizontalLayout_2
	horizontalLayout_2 = new HorizontalLayout();
	horizontalLayout_2.setImmediate(false);
	horizontalLayout_2.setWidth("-1px");
	horizontalLayout_2.setHeight("-1px");
	horizontalLayout_2.setMargin(false);
	
	// table_1
	table_1 = new Table();
	table_1.setImmediate(false);
	table_1.setWidth("-1px");
	table_1.setHeight("-1px");
	horizontalLayout_2.addComponent(table_1);
	
	// button_2
	button_2 = new Button();
	button_2.setCaption("Pokaż książki");
	button_2.setImmediate(false);
	button_2.setWidth("-1px");
	button_2.setHeight("-1px");
	horizontalLayout_2.addComponent(button_2);
	mainLayout.addComponent(horizontalLayout_2, "top:0.0px;left:0.0px;");
	setContent(mainLayout);
	}
}

I was trying to put in the listener:
getApplication().setMainWindow(showGUI);
But this didn’t give any results.
I hope you can help me :wink:

setMainWindow does not change existing UIs, only what window is served to the next browser accessing the application. To change the UI for an existing application, you need to use getMainWindow.setContent(newContent) instead, where newContent is any Layout.
