The TQWizard 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> TQWizard 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="tqwidget.html">TQWidget</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> TQWizard 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>
Constructs an empty wizard dialog. The <em>parent</em>, <em>name</em>, <em>modal</em> and <em>f</em> arguments are passed to the <a href="ntqdialog.html">TQDialog</a> constructor.
<h3 class=fn><a name="~TQWizard"></a>TQWizard::~TQWizard ()
</h3>
Destroys the object and frees any allocated resources, including
all pages and controllers.
<h3 class=fn>void <a name="addPage"></a>TQWizard::addPage ( <a href="tqwidget.html">TQWidget</a> * page, const <a href="tqstring.html">TQString</a> & title )<tt> [virtual]</tt>

</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 TQWizard 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>void <a name="back"></a>TQWizard::back ()<tt> [virtual protected slot]</tt>

<h3 class=fn><a href="ntqpushbutton.html">TQPushButton</a> * <a name="backButton"></a>TQWizard::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 TQWizard subclass. Use
<a href="#setBackEnabled">setBackEnabled</a>() to enable/disable this button.

slot, which is virtual so you can reimplement it in a TQWizard
subclass.
<h3 class=fn><a href="tqwidget.html">TQWidget</a> * <a name="currentPage"></a>TQWizard::currentPage () const
</h3>
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.
<h3 class=fn><a href="ntqpushbutton.html">TQPushButton</a> * <a name="finishButton"></a>TQWizard::finishButton () const
</h3>
Returns a pointer to the dialog's Finish button
<p> By default, this button is connected to the <a href="ntqdialog.html#accept">TQDialog::accept</a>()
slot, which is virtual so you can reimplement it in a TQWizard
subclass. Use <a href="#setFinishEnabled">setFinishEnabled</a>() to enable/disable this button.
<h3 class=fn>void <a name="help"></a>TQWizard::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 TQWizard subclass. Use
<a href="#setHelpEnabled">setHelpEnabled</a>() to enable/disable this button.
<h3 class=fn>void <a name="helpClicked"></a>TQWizard::helpClicked ()<tt> [signal]</tt>

</h3>
Inserts <em>page</em> at position <em>index</em> into the page sequence, with

the bottom divider.
<p> <em>layout</em> is the horizontal layout of the entire wizard.
<h3 class=fn>void <a name="layOutTitleRow"></a>TQWizard::layOutTitleRow ( <a href="qhboxlayout.html">TQHBoxLayout</a> * layout, const <a href="tqstring.html">TQString</a> & title )<tt> [virtual protected]</tt>

the next relevant page in the sequence.

<p> By default, this button is connected to the <a href="#next">next</a>() slot, which is
virtual so you can reimplement it in a TQWizard subclass. Use

<h3 class=fn>void <a name="setFinish"></a>TQWizard::setFinish ( <a href="tqwidget.html">TQWidget</a> *, bool )<tt> [virtual slot]</tt>
</h3>

</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>TQWizard::setHelpEnabled ( <a href="tqwidget.html">TQWidget</a> * page, bool enable )<tt> [virtual slot]</tt>
</h3>

</h3>
Sets the title for page <em>page</em> to <em>title</em>.
<h3 class=fn>void <a name="setTitleFont"></a>TQWizard::setTitleFont ( const <a href="ntqfont.html">TQFont</a> & )

<h3 class=fn>void <a name="showPage"></a>TQWizard::showPage ( <a href="tqwidget.html">TQWidget</a> * page )<tt> [virtual]</tt>
</h3>
Makes <em>page</em> the current page and emits the <a href="#selected">selected</a>() signal.
<p> This virtual function is called whenever a different page is to
be shown, including the first time the TQWizard is shown.
By reimplementing it (and calling <a href="#showPage">TQWizard::showPage</a>()),
you can prepare each page prior to it being shown.
<p>Examples: <a href="distributor-example.html#x2673">distributor/distributor.ui.h</a> and <a href="wizard-example.html#x15">wizard/wizard.cpp</a>.
