|
|---|
| 94 | The QWizard class provides a framework for wizard dialogs.
|
|---|
| 95 | <p>
|
|---|
| 96 |
|
|---|
| 97 |
|
|---|
| 98 |
|
|---|
| 99 | <p> A wizard is a special type of input dialog that consists of a
|
|---|
| 100 | sequence of dialog pages. A wizard's purpose is to walk the user
|
|---|
| 101 | through a process step by step. Wizards are useful for complex or
|
|---|
| 102 | infrequently occurring tasks that people may find difficult to
|
|---|
| 103 | learn or do.
|
|---|
| 104 | <p> QWizard provides page titles and displays Next, Back, Finish,
|
|---|
| 105 | Cancel, and Help push buttons, as appropriate to the current
|
|---|
| 106 | position in the page sequence. These buttons can be
|
|---|
| 107 | enabled/disabled using <a href="#setBackEnabled">setBackEnabled</a>(), <a href="#setNextEnabled">setNextEnabled</a>(),
|
|---|
| 108 | <a href="#setFinishEnabled">setFinishEnabled</a>() and <a href="#setHelpEnabled">setHelpEnabled</a>().
|
|---|
| 109 | <p> Create and populate dialog pages that inherit from <a href="qwidget.html">QWidget</a> and add
|
|---|
| 110 | them to the wizard using <a href="#addPage">addPage</a>(). Use <a href="#insertPage">insertPage</a>() to add a
|
|---|
| 111 | dialog page at a certain position in the page sequence. Use
|
|---|
| 112 | <a href="#removePage">removePage</a>() to remove a page from the page sequence.
|
|---|
| 113 | <p> Use <a href="#currentPage">currentPage</a>() to retrieve a pointer to the currently displayed
|
|---|
| 114 | page. <a href="#page">page</a>() returns a pointer to the page at a certain position
|
|---|
| 115 | in the page sequence.
|
|---|
| 116 | <p> Use <a href="#pageCount">pageCount</a>() to retrieve the total number of pages in the page
|
|---|
| 117 | sequence. <a href="#indexOf">indexOf</a>() will return the index of a page in the page
|
|---|
| 118 | sequence.
|
|---|
| 119 | <p> QWizard provides functionality to mark pages as appropriate (or
|
|---|
| 120 | not) in the current context with <a href="#setAppropriate">setAppropriate</a>(). The idea is
|
|---|
| 121 | that a page may be irrelevant and should be skipped depending on
|
|---|
| 122 | the data entered by the user on a preceding page.
|
|---|
| 123 | <p> It is generally considered good design to provide a greater number
|
|---|
| 124 | of simple pages with fewer choices rather than a smaller number of
|
|---|
| 125 | complex pages.
|
|---|
| 126 | <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>

| 147 | Called when the Next button is clicked; this virtual function
|
|---|
| 148 | returns TRUE if <em>page</em> is relevant for display in the current
|
|---|
| 149 | context; otherwise it is ignored by QWizard and returns FALSE. The
