Constructor Detail

WizardDescriptor

public WizardDescriptor(WizardDescriptor.Panel[] wizardPanels,
                        Object settings)
Create a new wizard from a fixed list of panels, passing some settings to the panels.

See Also:
WizardDescriptor(WizardDescriptor.Iterator, Object)

WizardDescriptor

public WizardDescriptor(WizardDescriptor.Panel[] wizardPanels)
Create a new wizard from a fixed list of panels with settings defaulted to this.

Parameters:
wizardPanels - the panels to use
See Also:
WizardDescriptor(WizardDescriptor.Iterator, Object)

WizardDescriptor

public WizardDescriptor(WizardDescriptor.Iterator panels,
                        Object settings)
Create wizard for a sequence of panels, passing some settings to the panels.

Parameters:
panels - iterator over all WizardDescriptor.Panels that can appear in the wizard
settings - the settings to provide to the panels (may be any data understood by them)
See Also:
WizardDescriptor.Panel.readSettings(java.lang.Object), WizardDescriptor.Panel.storeSettings(java.lang.Object)

WizardDescriptor

public WizardDescriptor(WizardDescriptor.Iterator panels)
Create wizard for a sequence of panels, with settings defaulted to this.

Parameters:
panels - iterator over all WizardDescriptor.Panels that can appear in the wizard
Method Detail

initialize

protected void initialize()
Initializes settings.

Overrides:
initialize in class NotifyDescriptor

setPanels

public final void setPanels(WizardDescriptor.Iterator panels)
Set a different list of panels. Correctly updates the buttons.

Parameters:
panels - the new list of WizardDescriptor.Panels

setOptions

public void setOptions(Object[] options)
Set options permitted by the wizard considered as a DialogDescriptor. Substitutes tokens such as NEXT_OPTION with the actual button.

Overrides:
setOptions in class NotifyDescriptor
Parameters:
options - the options to set
See Also:
NotifyDescriptor.getOptions()

setAdditionalOptions

public void setAdditionalOptions(Object[] options)
Description copied from class: NotifyDescriptor
Define an explicit description of the set of additional user-selectable options. Additional options are supposed to be used for help button, etc.

The usual value for the options parameter is an array of Strings. But the parameter type is an array of Objects. Its interpretation depends on its type:

Component
The component is added to the button row directly.
Icon
A JButton is created with this icon as its label.
anything else
The Object is converted to a string and the result is used to label a JButton.

Overrides:
setAdditionalOptions in class NotifyDescriptor
Parameters:
options - the options to set
See Also:
NotifyDescriptor.getOptions()

setClosingOptions

public void setClosingOptions(Object[] options)
Description copied from class: DialogDescriptor
Setter for list of options that close the dialog. Special values are:
  • null - all options will close the dialog
  • empty array - no option will close the dialog

Overrides:
setClosingOptions in class DialogDescriptor
Parameters:
options - the options to set

getValue

public Object getValue()
Overriden to ensure that returned value is one of the XXX_OPTION constants.

Overrides:
getValue in class NotifyDescriptor
Returns:
an Object indicating the option selected by the user
See Also:
NotifyDescriptor.setValue(java.lang.Object)

setTitleFormat

public void setTitleFormat(MessageFormat format)
Sets the message format to create title of the wizard. The format can take two parameters. The name of the current component and the name returned by the iterator that defines the order of panels. The default value is something like
   {0} wizard {1}
 
That can be expanded to something like this
   EJB wizard (1 of 8)
 
This method allows anybody to provide own title format.

Parameters:
format - message format to the title

getTitleFormat

public MessageFormat getTitleFormat()
Getter for current format to be used to format title.

Returns:
the format
See Also:
setTitleFormat(java.text.MessageFormat)

putProperty

public void putProperty(String name,
                        Object value)
Allows Panels that use WizardDescriptor as settings object to store additional settings into it.

Parameters:
name - name of the property
value - value of property

getProperty

public Object getProperty(String name)
Getter for stored property.

Parameters:
name - name of the property
Returns:
the value

setHelpCtx

public void setHelpCtx(HelpCtx helpCtx)
Description copied from class: DialogDescriptor
Set new help context for this dialog descriptor. Fires property change event if successful.

The implementation should automatically display a help button among the secondary options, without your needing to specify it, if the help context on the descriptor is neither null nor HelpCtx.DEFAULT_HELP. If the descriptor is null, this feature will be disabled (you can still add your own help button manually if you wish, of course). If DEFAULT_HELP (the default), normally the button will also be disabled, however if the inner pane is a component and this component has an associated help ID, that will be used automatically. So most users should never need to manually add a help button: call this method with the correct context, or associate an ID with the displayed component. Note that to set it to null you must explicitly call this method; passing null in the constructor actually sets it to DEFAULT_HELP.

Overrides:
setHelpCtx in class DialogDescriptor
Parameters:
helpCtx - new help context, can be null (no help)
See Also:
DialogDescriptor.getHelpCtx()

getInstantiatedObjects

public Set getInstantiatedObjects()
Returns set of newly instantiated objects if the wizard has been correctly finished. Returns the empty set as default. If the wizard uses the InstantiatingIterator then WizardDescriptor returns a set of Object as same as InstantiatingIterator.instantiate().

Returns:
a set of Objects created
Throws:
IllegalStateException - if this method is called on the unfinished wizard
Since:
4.41

updateState

protected void updateState()
Updates buttons to reflect the current state of the panels. Can be overridden by subclasses to change the options to special values. In such a case use:

   super.updateState ();
   setOptions (...);
 


setValue

public void setValue(Object value)
Overrides superclass method. Adds reseting of wizard for CLOSED_OPTION.

Overrides:
setValue in class NotifyDescriptor
Parameters:
value - the chosen value
See Also:
NotifyDescriptor.getValue()
