A View Manager in Vaadin
One of the problems I faced early on in developing a Vaadin Application was how to move from one screen to the next. I managed to find a example pattern which is based on a "View Manager". This object is responsible for maintaining the various screens within the application. At any point you can ask the "Manager" for a previous screen and you can display its contents. The example I found that uses this pattern is called the " Gas Diary ". The View Manager class itself contains a HaspMap and a Stack. The HashMap contains a string for the name of the view and a Layout. The Stack contains a Layout. In the Gas Diary Main Application the Login Screen is "switched" to via this process. setMainWindow(mainWindow); viewManager = new ViewManager(mainWindow); // Create the login screen viewManager.switchScreen(LoginScreen.class.getName(), new LoginScreen()); This method has worked for me...
