Getting Started

Notice that this page is written for the Wizards for Vaadin version 1.0.0-beta1. If you are using some other version, the API might differ and all features might not be available.

Starting from version 1.0.0-beta1 Wizards for Vaadin supports only Vaadin 7. The Vaadin 6 branch is no longer maintained.


Install the add-on to your Vaadin project by simply copying the JAR file from Vaadin Directory or add the add-on to your project using Maven or Ivy (see the Maven/Ivy configuration snippet required from Vaadin Directory).

If you want to build it yourself:

mvn clean install
cd wizards-for-vaadin-demo
mvn jetty:run

Basic Usage

Each step of your wizard must implement the WizardStep interface and provide the actual content as the return value of the getContent() method. You should add these steps to the wizard by calling the addStep(WizardStep) method of an Wizard instance.

// instantiate the Wizard
Wizard wizard = new Wizard();

// add some steps that implement the WizardStep interface
wizard.addStep(new FirstStep());
wizard.addStep(new SecondStep());
wizard.addStep(new ThirdStep());
wizard.addStep(new FourthStep());

// add the wizard to a layout

Lifecycle Events of the Wizard

To listen for the completion, cancellation or progress of the wizard, you should add a listener that implements the WizardProgressListener interface.

// add WizardProgressListener (assuming MyWizardListener implements the interface)
wizard.addListener(new MyWizardListener());

By default every Wizard instance have one WizardProgressListener assigned. This is the default progress bar displayed as the header of the Wizard. If you would like to remove it, you can remove the header by calling setHeader(null). A good practice is also to remove it from listening to the events. You can do it with the following code.

Component defaultHeader = wizard.getHeader();
if (defaultHeader instanceof WizardProgressListener) {
    wizard.removeListener((WizardProgressListener) defaultHeader);

Of course you can also leave the default header as a listener and attach it into your own layout.

Localization of the Button Captions

The wizard doesn't provide any specific support for localizing the button captions ("Next", "Back", "Finish", "Cancel"). Instead you need to assign the captions yourself. See the example below on how to provide Finnish translations.


Navigation with URL Fragments

Each WizardStep gets an identifier that can be used as the URI fragment for the step. This enables you to navigate between the steps with the back/forward buttons in your browser (see the demo application for an example of this). To enable the URI fragment navigation, call setUriFragmentEnabled(true) on the Wizard. To provide your own identifiers instead of using the automatically generated, you should add the WizardSteps with the overloaded addStep(WizardStep, String) method.
