The QWizard class provides a framework for wizard dialogs.
<p> 



<p> 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.
<p> 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 <a href="#setBackEnabled">setBackEnabled</a>(), <a href="#setNextEnabled">setNextEnabled</a>(),
<a href="#setFinishEnabled">setFinishEnabled</a>() and <a href="#setHelpEnabled">setHelpEnabled</a>().
<p> Create and populate dialog pages that inherit from <a href="qwidget.html">QWidget</a> and add
them to the wizard using <a href="#addPage">addPage</a>(). Use <a href="#insertPage">insertPage</a>() to add a
dialog page at a certain position in the page sequence. Use
<a href="#removePage">removePage</a>() to remove a page from the page sequence.
<p> Use <a href="#currentPage">currentPage</a>() to retrieve a pointer to the currently displayed
page. <a href="#page">page</a>() returns a pointer to the page at a certain position
in the page sequence.
<p> Use <a href="#pageCount">pageCount</a>() to retrieve the total number of pages in the page
sequence. <a href="#indexOf">indexOf</a>() will return the index of a page in the page
sequence.
<p> QWizard provides functionality to mark pages as appropriate (or
not) in the current context with <a href="#setAppropriate">setAppropriate</a>(). 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.
<p> 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.
<p> Example code is available here: <a href="wizard-wizard-cpp.html">wizard/wizard.cpp</a> <a href="wizard-wizard-h.html">wizard/wizard.h</a>

</h3>
Destroys the object and frees any allocated resources, including
all pages and controllers.

</h3>
Called when the Next button is clicked; this virtual function
returns TRUE if <em>page</em> 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
<a href="#setAppropriate">setAppropriate</a>(). The ultimate default is TRUE.
<p> <b>Warning:</b> The last page of the wizard will be displayed if no page
is relevant in the current context.

<h3 class=fn><a href="qpushbutton.html">QPushButton</a>&nbsp;* <a name="backButton"></a>QWizard::backButton () const
</h3>
Returns a pointer to the dialog's Back button
<p> By default, this button is connected to the <a href="#back">back</a>() slot, which is
virtual so you can reimplement it in a QWizard subclass. Use

subclass.

<h3 class=fn><a href="qwidget.html">QWidget</a>&nbsp;* <a name="currentPage"></a>QWizard::currentPage () const

it can be if you try hard enough.

</h3>
Returns a pointer to the dialog's Finish button
<p> By default, this button is connected to the <a href="qdialog.html#accept">QDialog::accept</a>()
slot, which is virtual so you can reimplement it in a QWizard
subclass. Use <a href="#setFinishEnabled">setFinishEnabled</a>() to enable/disable this button.

<h3 class=fn>void <a name="help"></a>QWizard::help ()<tt> [virtual protected slot]</tt>

</h3>
Returns a pointer to the dialog's Help button
<p> By default, this button is connected to the <a href="#help">help</a>() slot, which is
virtual so you can reimplement it in a QWizard subclass. Use
<a href="#setHelpEnabled">setHelpEnabled</a>() to enable/disable this button.

<h3 class=fn>void <a name="helpClicked"></a>QWizard::helpClicked ()<tt> [signal]</tt>
</h3>

</h3>
Returns the position of page <em>page</em>. If the page is not part of
the wizard -1 is returned.

<h3 class=fn>void <a name="insertPage"></a>QWizard::insertPage ( <a href="qwidget.html">QWidget</a>&nbsp;*&nbsp;page, const&nbsp;<a href="qstring.html">QString</a>&nbsp;&amp;&nbsp;title, int&nbsp;index )<tt> [virtual]</tt>
</h3>
Inserts <em>page</em> at position <em>index</em> into the page sequence, with
title <em>title</em>. If <em>index</em> is -1, the page will be appended to

<h3 class=fn>void <a name="layOutButtonRow"></a>QWizard::layOutButtonRow ( <a href="qhboxlayout.html">QHBoxLayout</a>&nbsp;*&nbsp;layout )<tt> [virtual protected]</tt>
</h3>
This virtual function is responsible for adding the buttons below
the bottom divider.
<p> <em>layout</em> is the horizontal layout of the entire wizard.

<h3 class=fn>void <a name="layOutTitleRow"></a>QWizard::layOutTitleRow ( <a href="qhboxlayout.html">QHBoxLayout</a>&nbsp;*&nbsp;layout, const&nbsp;<a href="qstring.html">QString</a>&nbsp;&amp;&nbsp;title )<tt> [virtual protected]</tt>
</h3>
This virtual function is responsible for laying out the title row.

time <em>title</em> changes.

<h3 class=fn>void <a name="next"></a>QWizard::next ()<tt> [virtual protected slot]</tt>
</h3>
Called when the user clicks the Next button, this function shows
the next relevant page in the sequence.
<p> <p>See also <a href="#appropriate">appropriate</a>().

</h3>
If <em>appropriate</em> is TRUE then page <em>page</em> is considered relevant

</h3>
If <em>enable</em> is TRUE, page <em>page</em> has a Finish button; otherwise
<em>page</em> has no Finish button. By default <em>no</em> page has this
button.

<h3 class=fn>void <a name="setHelpEnabled"></a>QWizard::setHelpEnabled ( <a href="qwidget.html">QWidget</a>&nbsp;*&nbsp;page, bool&nbsp;enable )<tt> [virtual slot]</tt>

<p> 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 <a href="#showPage">QWizard::showPage</a>()),
you can prepare each page prior to it being shown.
