public class UICWizard

extends JPanel

The UICWizard class provides a framework for wizard dialogs. A wizard is a special type of input dialog that consists of a sequence of dialog pages. A wizard's purpose is to walk the user through a process step by step. Wizards are useful for complex or infrequently occurring tasks that people may find difficult to learn or do. UICWizard provides page titles and displays Next, Back, Finish, Cancel buttons, depending on the current position in the page sequence.

Extend or simply populate the wizard by adding pages using addPage and insertPage.

You can adjust the page sequence by setting unwanted pages to not appropriate using the setAppropriate method.

Disallowing the next button to be pressed on certain pages can be done by setting the page to be not verified, which can be done by calling the setVerified method.

The actual starting, or showing, of the Wizard is done via the showWizard method.

It is generally considered good design to provide a greater number of simple pages with fewer choices rather than a smaller number of complex pages

Parameters:

successfull - true if the wizard is left on finish, false otherwise

addPage

public void addPage(JComponent page)

Parameters:

page - the component that represents a page; notice that the page title is fetched from the name of the page.

See Also:

Component.setName(String)

insertPage

public void insertPage(JComponent page,
                       int index)
                throws IndexOutOfBoundsException

Insert a page somewhere in the list.

Parameters:

Parameters:

page - the old page

getCurrentPage

public JComponent getCurrentPage()

Return the currently showing page.

Returns:

the currently showing page, or null when no page is being shown.

isAppropriate

public boolean isAppropriate(JComponent page)

A page will only be shown when it is appropriate. Find out if a certain page will be shown or skipped when the next or prev button is pressed that would make the argument page the current page.

Parameters:

page - a page previously added or inserted.

Returns:

wheater the page will be shown

setAppropriate

public void setAppropriate(JComponent page,
                           boolean appropriate)

A page will only be shown when it is appropriate. Set a certain page to be shown or skipped when the next or prev button is pressed that would make the argument page the current page.

Parameters:

page - a page previously added or inserted.

appropriate - true means that page will be shown

getPage

public JComponent getPage(int index)

Returns:

the page at index, or null when no page could be found.

setVerified

public void setVerified(JComponent page,
                        boolean verified)

Alter the next button being enabled at the argument page. While a panel is not verified the next button is not enabled. The panels are all verified when added by default.

Parameters:

page - the page to set to verified

verified - value for panel verification.

isVerified

public boolean isVerified(JComponent page)

buttonPrevPressedSlot

protected void buttonPrevPressedSlot()

a slot which is called by the button

buttonNextPressedSlot

protected void buttonNextPressedSlot()

a slot which is called by the button

showWizard

public boolean showWizard(Window parent,
                          String title,
                          boolean modal)

Open a new dialog with the first appropriate page being shown.

Call this method to launch the wizard in its own window and return only after the wizard has finished (i.e. the dialog has been closed).

Notice that since this method will not immidiately return it is unwise to start it in the EventDispatch Thread. The EventDispatch thread is used when you call this method from code that is initiated from user-inter action. Button presses are a good example. In the case of a modal dialog the problem will be solved by AWT internals, in other cases you must create a new thread which will show this wizard.

An example call for a non-modal dialog (a non-modal dialog should be used in all but the most extreme cases)

          if(myWizard.showWizard(null, "myWizard", false)) {
              // get data from wizard and do something with it.
              newAssignment(myWizard.getAssignment());
          }
  

In the case you call the showWizard from a buttonPress or other GUI action you have to do a little extra; here is some example code:

      final UICWizard daWizard = myWizard;
      Thread handling = new Thread("WizardHandler") {
          public void run() {
              if(! daWizard.showWizard(null, "myWizard", false))
                  return; // was cancelled
              // after we return we get all the info from the wizard, for example
              // by calling a custom method on myWizard that extends from UICWizard
              newAssignment(myWizard.getAssignment());
          }
      };
      handling.start();
  

Parameters:

parent - the parent Window that the new dialog will beloing to.

title - the string that will be used as the title of the new dialog.

modal - true means the parent window will be locked as long as the wizard is open.

Returns:

success of the Wizard. Will return true when the finished button has been pressed.

Throws:

IllegalStateException - since this method will not return until the wizard has been closed we can not be non-modal (modal = false) and be called from the EventDispatch Thread.

showWizard

public boolean showWizard(Window parent,
                          String title,
                          boolean modal,
                          Dimension sizeHint)

Open a new dialog with the first appropriate page being shown.

Parameters:

parent - the parent Window that the new dialog will beloing to.

title - the string that will be used as the title of the new dialog.

modal - true means the parent window will be locked as long as the wizard is open.

sizeHint - A size hint for the Wizard. This will be used as a preferred size.

Returns:

success of the Wizard. Will return true when the finished button has been pressed.

Throws:

IllegalStateException - since this method will not return until the wizard has been closed we can not be non-modal (modal = false) and be called from the EventDispatch Thread.
