DESCRIPTION
The QWizard 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.

QWizard provides page titles and displays Next, Back, Finish, Cancel, and Help push buttons, as appropriate to the current position in the page sequence. These buttons can be enabled/disabled using setBackEnabled(), setNextEnabled(), setFinishEnabled() and setHelpEnabled().

Create and populate dialog pages that inherit from QWidget and add them to the wizard using addPage(). Use insertPage() to add a dialog page at a certain position in the page sequence. Use removePage() to remove a page from the page sequence.

Use currentPage() to retrieve a pointer to the currently displayed page. page() returns a pointer to the page at a certain position in the page sequence.

Use pageCount() to retrieve the total number of pages in the page sequence. indexOf() will return the index of a page in the page sequence.

QWizard provides functionality to mark pages as appropriate (or not) in the current context with setAppropriate(). The idea is that a page may be irrelevant and should be skipped depending on the data entered by the user on a preceding page.

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.

Example code is available here: wizard/wizard.cpp wizard/wizard.h

MEMBER FUNCTION DOCUMENTATION

QWizard::QWizard ( QWidget * parent = 0, const char * name = 0, bool modal = FALSE, WFlags f = 0 )
Constructs an empty wizard dialog. The parent, name, modal and f arguments are passed to the QDialog constructor.

QWizard::~QWizard ()
Destroys the object and frees any allocated resources, including all pages and controllers.

void QWizard::addPage ( QWidget * page, const QString & title ) [virtual]
Adds page to the end of the page sequence, with the title, title.

bool QWizard::appropriate ( QWidget * page ) const [virtual]
Called when the Next button is clicked; this virtual function returns TRUE if page is relevant for display in the current context; otherwise it is ignored by QWizard and returns FALSE. The default implementation returns the value set using setAppropriate(). The ultimate default is TRUE.

Warning: The last page of the wizard will be displayed if no page is relevant in the current context.

void QWizard::back () [virtual protected slot]
Called when the user clicks the Back button; this function shows the preceding relevant page in the sequence.

See also appropriate().

QPushButton * QWizard::backButton () const
Returns a pointer to the dialog's Back button

By default, this button is connected to the back() slot, which is virtual so you can reimplement it in a QWizard subclass. Use setBackEnabled() to enable/disable this button.

QPushButton * QWizard::cancelButton () const
Returns a pointer to the dialog's Cancel button

By default, this button is connected to the QDialog::reject() slot, which is virtual so you can reimplement it in a QWizard subclass.

QWidget * QWizard::currentPage () const
Returns a pointer to the current page in the sequence. Although the wizard does its best to make sure that this value is never 0, it can be if you try hard enough.

QPushButton * QWizard::finishButton () const
Returns a pointer to the dialog's Finish button

By default, this button is connected to the QDialog::accept() slot, which is virtual so you can reimplement it in a QWizard subclass. Use setFinishEnabled() to enable/disable this button.

void QWizard::help () [virtual protected slot]
Called when the user clicks the Help button, this function emits the helpClicked() signal.

QPushButton * QWizard::helpButton () const
Returns a pointer to the dialog's Help button

By default, this button is connected to the help() slot, which is virtual so you can reimplement it in a QWizard subclass. Use setHelpEnabled() to enable/disable this button.

void QWizard::helpClicked () [signal]
This signal is emitted when the user clicks on the Help button.

int QWizard::indexOf ( QWidget * page ) const
Returns the position of page page. If the page is not part of the wizard -1 is returned.

void QWizard::insertPage ( QWidget * page, const QString & title, int index ) [virtual]
Inserts page at position index into the page sequence, with title title. If index is -1, the page will be appended to the end of the wizard's page sequence.

void QWizard::layOutButtonRow ( QHBoxLayout * layout ) [virtual protected]
This virtual function is responsible for adding the buttons below the bottom divider.

layout is the horizontal layout of the entire wizard.

void QWizard::layOutTitleRow ( QHBoxLayout * layout, const QString & title ) [virtual protected]
This virtual function is responsible for laying out the title row.

layout is the horizontal layout for the wizard, and title is the title for this page. This function is called every time title changes.

void QWizard::next () [virtual protected slot]
Called when the user clicks the Next button, this function shows the next relevant page in the sequence.

See also appropriate().

QPushButton * QWizard::nextButton () const
Returns a pointer to the dialog's Next button

By default, this button is connected to the next() slot, which is virtual so you can reimplement it in a QWizard subclass. Use setNextEnabled() to enable/disable this button.

QWidget * QWizard::page ( int index ) const
Returns a pointer to the page at position index in the sequence, or 0 if index is out of range. The first page has index 0.

int QWizard::pageCount () const
Returns the number of pages in the wizard.

void QWizard::removePage ( QWidget * page ) [virtual]
Removes page from the page sequence but does not delete the page. If page is currently being displayed, QWizard will display the page that precedes it, or the first page if this was the first page.

void QWizard::selected ( const QString & ) [signal]
This signal is emitted when the current page changes. The parameter contains the title of the selected page.

void QWizard::setAppropriate ( QWidget * page, bool appropriate ) [virtual]
If appropriate is TRUE then page page is considered relevant in the current context and should be displayed in the page sequence; otherwise page should not be displayed in the page sequence.

See also appropriate().

void QWizard::setBackEnabled ( QWidget * page, bool enable ) [virtual slot]
If enable is TRUE, page page has a Back button; otherwise page has no Back button. By default all pages have this button.

void QWizard::setFinish ( QWidget *, bool ) [virtual slot]
This function is obsolete. It is provided to keep old source working. We strongly advise against using it in new code.

Use setFinishEnabled instead

void QWizard::setFinishEnabled ( QWidget * page, bool enable ) [virtual slot]
If enable is TRUE, page page has a Finish button; otherwise page has no Finish button. By default no page has this button.

void QWizard::setHelpEnabled ( QWidget * page, bool enable ) [virtual slot]
If enable is TRUE, page page has a Help button; otherwise page has no Help button. By default all pages have this button.

void QWizard::setNextEnabled ( QWidget * page, bool enable ) [virtual slot]
If enable is TRUE, page page has a Next button; otherwise the Next button on page is disabled. By default all pages have this button.

void QWizard::setTitle ( QWidget * page, const QString & title )
Sets the title for page page to title.

void QWizard::setTitleFont ( const QFont & )
Sets the font used for page titles. See the "titleFont" property for details.

void QWizard::showPage ( QWidget * page ) [virtual]
Makes page the current page and emits the selected() signal.

This virtual function is called whenever a different page is to be shown, including the first time the QWizard is shown. By reimplementing it (and calling QWizard::showPage()), you can prepare each page prior to it being shown.

Examples:

QString QWizard::title ( QWidget * page ) const
Returns the title of page page.

QFont QWizard::titleFont () const
Returns the font used for page titles. See the "titleFont" property for details.

  Property Documentation

QFont titleFont
This property holds the font used for page titles.

The default is QApplication::font().

Set this property's value with setTitleFont() and get this property's value with titleFont().
