wicket.extensions.wizard .WizardModel

WizardModel

public class WizardModel implements IWizardModel(Code)

Default implementation of IWizardModel .

Steps can be added to this model directly using either the WizardModel.add(IWizardStep) normal add method or WizardModel.add(IWizardStep,wicket.extensions.wizard.WizardModel.ICondition) the conditional add method .

Swing Wizard Framework served as a valuable source of inspiration.

Field Detail

TRUE
final public static ICondition TRUE(Code)
	Condition that always evaluates true.

Constructor Detail

WizardModel
public WizardModel()(Code)
	Construct.

Method Detail

add
public void add(IWizardStep step)(Code)
	Adds the next step to the wizard. If the WizardStep implements ICondition , then this method is equivalent to calling WizardModel.add(IWizardStep,ICondition) add(step, (ICondition)step) . Parameters: step - the step to added.

add
public void add(IWizardStep step, ICondition condition)(Code)
	Adds an optional step to the model. The step will only be displayed if the specified condition is met. Parameters: step - The step to add Parameters: condition - the ICondition under which it should be included inthe wizard.

addListener
final public void addListener(IWizardModelListener listener)(Code)
	Adds a wizard model listener. Parameters: listener - The listener to add

allStepsComplete
final protected boolean allStepsComplete()(Code)
	Returns true if all the steps in the wizard return `true` from IWizardStep.isComplete . This is primarily used to determine if the last button can be enabled. `true` if all the steps in the wizard are complete,`false` otherwise.

cancel
public void cancel()(Code)
	This implementation just fires IWizardModelListener.onCancel a cancel event . Though this isn't a very strong contract, it gives all the power to the user of this model. See Also: wicket.extensions.wizard.IWizardModel.cancel

findLastStep
final protected IWizardStep findLastStep()(Code)
	Finds the last step in this model. The last step

findNextVisibleStep
final protected IWizardStep findNextVisibleStep()(Code)
	Finds the next visible step based on the active step. The next visible step based on the active step

finish
public void finish()(Code)
	This implementation just fires IWizardModelListener.onFinish a finish event . Though this isn't a very strong contract, it gives all the power to the user of this model. See Also: wicket.extensions.wizard.IWizardModel.finish

fireActiveStepChanged
final protected void fireActiveStepChanged(IWizardStep step)(Code)
	Notify listeners that the active step has changed. Parameters: step - The new step

fireWizardCancelled
final protected void fireWizardCancelled()(Code)
	Notify listeners that the wizard is finished.

fireWizardFinished
final protected void fireWizardFinished()(Code)
	Notify listeners that the wizard is finished.

getActiveStep
final public IWizardStep getActiveStep()(Code)
	Gets the current active step the wizard should display. the active step.

isCancelVisible
public boolean isCancelVisible()(Code)
	Gets whether cancel functionality is available. Whether cancel functionality is available

isLastAvailable
final public boolean isLastAvailable()(Code)
	Checks if the last button should be enabled. `true` if the last button should be enabled,`false` otherwise. See Also: WizardModel.isLastVisible

isLastStep
public boolean isLastStep(IWizardStep step)(Code)
	See Also: wicket.extensions.wizard.IWizardModel.isLastStep(wicket.extensions.wizard.IWizardStep)

isLastVisible
public boolean isLastVisible()(Code)
	Checks if the last button should be displayed. This method should only return true if the WizardModel.isLastAvailable will return true at any point. Returning false will prevent the last button from appearing on the wizard at all. `true` if the previou last should be displayed,`false` otherwise.

isNextAvailable
final public boolean isNextAvailable()(Code)
	Checks if the next button should be enabled. `true` if the next button should be enabled,`false` otherwise.

isPreviousAvailable
final public boolean isPreviousAvailable()(Code)
	Checks if the previous button should be enabled. `true` if the previous button should be enabled,`false` otherwise.

lastStep
public void lastStep()(Code)
	See Also: wicket.extensions.wizard.IWizardModel.lastStep

next
public void next()(Code)
	See Also: wicket.extensions.wizard.IWizardModel.next

previous
public void previous()(Code)
	See Also: wicket.extensions.wizard.IWizardModel.previous

removeListener
final public void removeListener(IWizardModelListener listener)(Code)
	Removes a wizard model listener. Parameters: listener - The listener to remove

reset
public void reset()(Code)
	See Also: wicket.extensions.wizard.IWizardModel.reset

setActiveStep
public void setActiveStep(IWizardStep step)(Code)
	Sets the active step. Parameters: step - the new active step step.

setCancelVisible
public void setCancelVisible(boolean cancelVisible)(Code)
	Sets whether cancel functionality is available. Parameters: cancelVisible - Whether cancel functionality is available

setLastVisible
public void setLastVisible(boolean lastVisible)(Code)
	Configures if the last button should be displayed. Parameters: lastVisible - `true` to display the last button, `false`otherwise. See Also: WizardModel.isLastVisible

stepIterator
final public Iterator stepIterator()(Code)
	See Also: wicket.extensions.wizard.IWizardModel.stepIterator
