Wizard Descriptor API

Class WizardDescriptor allows developer to create wizard from supplied WizardDescriptor.Iterator or array of WizardDesriptor.Panel.

WizardDescriptor can create wizard panel (steps, graphics, help on the left; subtitle and user panel on the right). To achieve that, developer have to use WizardDescriptor.putProperty() or JComponent.putClientProperty() in his/her panel to set needed properties (e.g. String[] for steps, URL for help, some Boolean for layout control, ...).

To create simple wizard try this:

WizardDescriptor wd = new WizardDescriptor(
    new WizardDescriptor.Panel[] { 
        myPanel1, 
        myPanel2, 
        myPanel3,
        myPanel4 
});

It will create four steps wizard with no additional graphic. To achieve creation of subtitle, steps pane, help tab, ... one have to set initialization properties.

Wizard panel initialization

Use WizardDescriptor.putProperty() to set following initialization properties.

Name "WizardPanel_autoWizardStyle", type Boolean The key property for layouting of wizard dialog. Recommended to be set Boolean.TRUE to most cases. If switch on WizardPanel_autoWizardStyle then wizard can display wizards steps on the left side, create a subtitle on active panel, display of error messages and others. Wizards infrastructure will check the properties: WizardPanel_contentDisplayed WizardPanel_helpDisplayed WizardPanel_contentNumbered If doesn't set or set to Boolean.FALSE then these properties are ignored. Also set to Boolean.TRUE to turn on subtitle creation from WizardDesriptor.Panel.getComponent().getName() as first and WizardDescriptor.Iterator.name() as second parameter in subtitle format set with WizardDesriptor.setTitleFormat(). Default subtitle format is "{0} wizard ({1})" and name of default WizardDescriptor.ArrayIterator is "{0} of {1}" where {0} is number of current panel and {1} is size of iterator.

Name "WizardPanel_contentDisplayed", type Boolean Set to Boolean.TRUE to turn on displaying of steps pane (content, behind which can be displayed image). Content will be constructed from not initialization property "WizardPanel_contentData".

Name "WizardPanel_helpDisplayed", type Boolean Set to Boolean.TRUE to turn on displaying of help (html browser) in a special tabbed pane of wizard panel. Help will be taken from not initialization property "WizardPanel_helpURL". If also steps are displayed then put help and content panes into tabbed pane. Note: If do you need a help on invoking the Help button then ensure a WizardDescriptor.Panel supply a non-default HelpCtx.

Name "WizardPanel_contentNumbered", type Boolean Set to Boolean.TRUE to turn on numbering of steps (before every step is placed it's sequence number).

Name "WizardPanel_leftDimension", type Dimension Set size of left pane (steps and help pane).

That was initialization part. All Boolean properties are Boolean.FALSE by default. Initialization properties could be set also in the first panel (through JComponent.putClientProperty()) of supplied iterator. Later change of these properties will not cause change of wizard behavior. Properties have to be set before TopManager.getDefault().createDialog(wd) is called.
Follow properties which could be changed at wizard runtime.

Wizard panel properties

These properties could be changed dynamically.

Name "WizardPanel_contentData", type String[] Set step names which will be displayed in the content pane.
Name "WizardPanel_image", type java.awt.Image Set image displayed as background of content.

Set subtitle (!!!) format with WizardDescriptor.setTitleFormat(). Set title of the wizard with WizardDescriptor.setTitle(). Name "WizardPanel_errorMessage", type String Set the localized message which is then shown at the bottom of the wizard panel. This message should be set when panel becomes invalid and Next/Finish buttons are disabled. It helps user to understand what is wrong. The property must be set to null value to clear the message. This property is supported since NetBeans 3.5.

In every panel set these client properties (JComponent.putClientProperty()): Name "WizardPanel_helpURL", type java.net.URL Help url which explains your pane. Name "WizardPanel_contentSelectedIndex", type java.lang.Integer Index of highlighted step in the content, the index is zero-based. Name "WizardPanel_contentBackgroundColor", type java.awt.Color Color used as background of content pane. Set name of panel JComponent.setName("First wizard panel"), used as first part of subtitle, second is WizardDescriptor.Panel.name() when you use "{0}{1}" message format. All properties could be set with both alternatives (WizardDescriptor.putProperty() or JComponent.putClientProperty()) except "WizardPanel_helpURL" which can be set only with JComponent.putClientProperty() and the property "WizardPanel_errorMessage" which can be set only by WizardDescriptor.putProperty(). If both are used at the same time then WizardDescriptor.putProperty() matters. WizardDescriptor listens on property changes of not initialization properties and makes immediate changes.
