public class QWizard
The QWizard
class provides a framework for wizards. A wizard (also called an assistant on Mac OS X) is a special type of input dialog that consists of a sequence of pages. A wizard's purpose is to guide the user through a process step by step. Wizards are useful for complex or infrequent tasks that users may find difficult to learn.
QWizard
inherits QDialog
and represents a wizard. Each page is a QWizardPage
(a QWidget
subclass). To create your own wizards, you can use these classes directly, or you can subclass them for more control.
Topics:
QWizardPage *createIntroPage() { QWizardPage *page = new QWizardPage; page->setTitle("Introduction"); QLabel *label = new QLabel("This wizard will help you register your copy " "of Super Product Two."); label->setWordWrap(true); QVBoxLayout *layout = new QVBoxLayout; layout->addWidget(label); page->setLayout(layout); return page; } QWizardPage *createRegistrationPage() { ... }
QWizardPage *createConclusionPage() { ... }
int main(int argc, char *argv[]) { QApplication app(argc, argv); QString translatorFileName = QLatin1String("qt_"); translatorFileName += QLocale::system().name(); QTranslator *translator = new QTranslator(&app); if (translator->load(translatorFileName, QLibraryInfo::location(QLibraryInfo::TranslationsPath))) app.installTranslator(translator); QWizard wizard; wizard.addPage(createIntroPage()); wizard.addPage(createRegistrationPage()); wizard.addPage(createConclusionPage()); wizard.setWindowTitle("Trivial Wizard"); wizard.show(); return app.exec(); }
QWizard
supports four wizard looks: You can explicitly set the look to use using setWizardStyle()
(e.g., if you want the same look on all platforms). Note: AeroStyle
has effect only on a Windows Vista system with alpha compositing enabled. ModernStyle
is used as a fallback when this condition is not met. In addition to the wizard style, there are several options that control the look and feel of the wizard. These can be set using setOption()
or setOptions()
. For example, HaveHelpButton
makes QWizard
show a Help button along with the other wizard buttons.
You can even change the order of the wizard buttons to any arbitrary order using setButtonLayout()
, and you can add up to three custom buttons (e.g., a Print button) to the button row. This is achieved by calling setButton()
or setButtonText()
with CustomButton1
, CustomButton2
, or CustomButton3
to set up the button, and by enabling the HaveCustomButton1
, HaveCustomButton2
, or HaveCustomButton3
options. Whenever the user clicks a custom button, customButtonClicked()
is emitted. For example:
The following code example is written in c++.
wizard()->setButtonText(QWizard::CustomButton1, tr("&Print")); wizard()->setOption(QWizard::HaveCustomButton1, true); connect(wizard(), SIGNAL(customButtonClicked(int)), this, SLOT(printButtonClicked()));
QWizardPage
s. At any time, only one page is shown. A page has the following attributes: title
.subTitle
.WatermarkPixmap
(used by ClassicStyle
and ModernStyle
)BannerPixmap
(used by ModernStyle
)LogoPixmap
(used by ClassicStyle
and ModernStyle
)BackgroundPixmap
(used by MacStyle
)QWizard
renders these attributes, assuming they are all present and ModernStyle
is used: subTitle
is set, QWizard
displays it in a header, in which case it also uses the BannerPixmap
and the LogoPixmap
to decorate the header. The WatermarkPixmap
is displayed on the left side, below the header. At the bottom, there is a row of buttons allowing the user to navigate through the pages. The page itself (the QWizardPage
widget) occupies the area between the header, the watermark, and the button row. Typically, the page is a QWizardPage
on which a QGridLayout
is installed, with standard child widgets (QLabel
s, QLineEdit
s, etc.).
If the wizard's style is MacStyle
, the page looks radically different:
MacStyle
. If the BackgroundPixmap
is set, it is used as the background for the wizard; otherwise, a default "assistant" image is used. The title and subtitle are set by calling QWizardPage::setTitle()
and QWizardPage::setSubTitle()
on the individual pages. They may be plain text or HTML (see titleFormat
and subTitleFormat
). The pixmaps can be set globally for the entire wizard using setPixmap()
, or on a per-page basis using QWizardPage::setPixmap()
.Registering and Using Fields
In many wizards, the contents of a page may affect the default values of the fields of a later page. To make it easy to communicate between pages, QWizard
supports a "field" mechanism that allows you to register a field (e.g., a QLineEdit
) on a page and to access its value from any page. It is also possible to specify mandatory fields (i.e., fields that must be filled before the user can advance to the next page).
To register a field, call QWizardPage::registerField()
field. For example:
The following code example is written in c++.
ClassInfoPage::ClassInfoPage(QWidget *parent) : QWizardPage(parent) { ... classNameLabel = new QLabel(tr("&Class name:")); classNameLineEdit = new QLineEdit; classNameLabel->setBuddy(classNameLineEdit); baseClassLabel = new QLabel(tr("B&ase class:")); baseClassLineEdit = new QLineEdit; baseClassLabel->setBuddy(baseClassLineEdit); qobjectMacroCheckBox = new QCheckBox(tr("Generate Q_OBJECT ¯o")); registerField("className*", classNameLineEdit); registerField("baseClass", baseClassLineEdit); registerField("qobjectMacro", qobjectMacroCheckBox); ... }The above code registers three fields, className, baseClass, and qobjectMacro, which are associated with three child widgets. The asterisk (*) next to className denotes a mandatory field. The fields of any page are accessible from any other page. For example:
void OutputFilesPage::initializePage() { QString className = field("className").toString(); headerLineEdit->setText(className.toLower() + ".h"); implementationLineEdit->setText(className.toLower() + ".cpp"); outputDirLineEdit->setText(QDir::convertSeparators(QDir::tempPath())); }Here, we call
QWizardPage::field()
to access the contents of the className field (which was defined in the ClassInfoPage) and use it to initialize the OuputFilePage. The field's contents is returned as a QVariant
. When we create a field using To consider a field "filled", The enabled/disabled state of the Next and/or Finish buttons is one way to perform validation on the user input. Another way is to reimplement QWizardPage::registerField()
, we pass a unique field name and a widget. We can also provide a Qt property name and a "changed" signal (a signal that is emitted when the property changes) as third and fourth arguments; however, this is not necessary for the most common Qt widgets, such as QLineEdit
, QCheckBox
, and QComboBox
, because QWizard
knows which properties to look for. If an asterisk (*) is appended to the name when the property is registered, the field is a mandatory field. When a page has mandatory fields, the Next and/or Finish buttons are enabled only when all mandatory fields are filled. QWizard
simply checks that the field's current value doesn't equal the original value (the value it had when initializePage()
was called). For QLineEdit
and QAbstractSpinBox
subclasses, QWizard
also checks that hasAcceptableInput()
returns true, to honor any validator or mask. QWizard
's mandatory field mechanism is provided for convenience. A more powerful (but also more cumbersome) alternative is to reimplement QWizardPage::isComplete()
and to emit the QWizardPage::completeChanged()
signal whenever the page becomes complete or incomplete. validateCurrentPage()
(or QWizardPage::validatePage()
) to perform some last-minute validation (and show an error message if the user has entered incomplete or invalid information). If the function returns true, the next page is shown (or the wizard finishes); otherwise, the current page stays up.Creating Linear Wizards
Most wizards have a linear structure, with page 1 followed by page 2 and so on until the last page. The Class Wizard example is such a wizard. With QWizard
, linear wizards are created by instantiating the QWizardPage
s and inserting them using addPage()
. By default, the pages are shown in the order in which they were added. For example:
The following code example is written in c++.
ClassWizard::ClassWizard(QWidget *parent)
: QWizard(parent)
{
addPage(new IntroPage);
addPage(new ClassInfoPage);
addPage(new CodeStylePage);
addPage(new OutputFilesPage);
addPage(new ConclusionPage);
...
}
When a page is about to be shown, QWizard
calls initializePage()
(which in turn calls QWizardPage::initializePage()
) to fill the page with default values. By default, this function does nothing, but it can be reimplemented to initialize the page's contents based on other pages' fields (see the example above
).
If the user presses Back, cleanupPage()
is called (which in turn calls QWizardPage::cleanupPage()
). The default implementation resets the page's fields to their original values (the values they had before initializePage()
was called). If you want the Back button to be non-destructive and keep the values entered by the user, simply enable the IndependentPages
option.Creating Non-Linear Wizards
Some wizards are more complex in that they allow different traversal paths based on the information provided by the user. The License Wizard example illustrates this. It provides five wizard pages; depending on which options are selected, the user can reach different pages.
class LicenseWizard : public QWizard { ... enum { Page_Intro, Page_Evaluate, Page_Register, Page_Details, Page_Conclusion }; ... };The pages are inserted using
setPage()
, which takes an ID and an instance of QWizardPage
(or of a subclass):LicenseWizard::LicenseWizard(QWidget *parent) : QWizard(parent) { setPage(Page_Intro, new IntroPage); setPage(Page_Evaluate, new EvaluatePage); setPage(Page_Register, new RegisterPage); setPage(Page_Details, new DetailsPage); setPage(Page_Conclusion, new ConclusionPage); ... }By default, the pages are shown in increasing ID order. To provide a dynamic order that depends on the options chosen by the user, we must reimplement
QWizardPage::nextId()
. For example:int IntroPage::nextId() const { if (evaluateRadioButton->isChecked()) { return LicenseWizard::Page_Evaluate; } else { return LicenseWizard::Page_Register; } }It would also be possible to put all the logic in one place, in a
int EvaluatePage::nextId() const { return LicenseWizard::Page_Conclusion; }
int RegisterPage::nextId() const { if (upgradeKeyLineEdit->text().isEmpty()) { return LicenseWizard::Page_Details; } else { return LicenseWizard::Page_Conclusion; } }
int DetailsPage::nextId() const { return LicenseWizard::Page_Conclusion; }
int ConclusionPage::nextId() const { return -1; }
QWizard::nextId()
reimplementation. For example: public int nextId() { switch (currentId()) { case Page_Intro: if (QVariant.toBoolean(field("intro.evaluate"))) { return Page_Evaluate; } else { return Page_Register; } case Page_Evaluate: return Page_Conclusion; case Page_Register: if (QVariant.toString(field("register.upgradeKey")).length() == 0) { return Page_Details; } else { return Page_Conclusion; } case Page_Details: return Page_Conclusion; case Page_Conclusion: default: return -1; } }To start at another page than the page with the lowest ID, call
setStartId()
. To test whether a page has been visited or not, call hasVisitedPage()
. For example:
The following code example is written in c++.
void ConclusionPage::initializePage() { QString licenseText; if (wizard()->hasVisitedPage(LicenseWizard::Page_Evaluate)) { licenseText = tr("<u>Evaluation License Agreement:</u> " "You can use this software for 30 days and make one " "backup, but you are not allowed to distribute it."); } else if (wizard()->hasVisitedPage(LicenseWizard::Page_Details)) { licenseText = tr("<u>First-Time License Agreement:</u> " "You can use this software subject to the license " "you will receive by email."); } else { licenseText = tr("<u>Upgrade License Agreement:</u> " "This software is licensed under the terms of your " "current license."); } bottomLabel->setText(licenseText); }

protected void cleanupPage(int id)
QWizard
to clean up page id just before the user leaves it by clicking Back (unless the QWizard::IndependentPages
option is set). The default implementation calls QWizardPage::cleanupPage()
on page(id).
QWizardPage::cleanupPage()
, and initializePage()
.
protected void initializePage(int id)
QWizard
to prepare page id just before it is shown as a result of the user clicking Next. (However, if the QWizard::IndependentPages
option is set, this function is only called the first time the page is shown.) By reimplementing this function, you can ensure that the page's fields are properly initialized based on fields from previous pages.
The default implementation calls QWizardPage::initializePage()
on page(id).
QWizardPage::initializePage()
, and cleanupPage()
.
public int nextId()
QWizard
to find out which page to show when the user clicks the Next button. The default implementation calls QWizardPage::nextId()
on the currentPage()
.
QWizardPage::nextId()
, and currentPage()
.
public boolean validateCurrentPage()
QWizard
when the user clicks Next or Finish to perform some last-minute validation. If it returns true, the next page is shown (or the wizard finishes); otherwise, the current page stays up. The default implementation calls QWizardPage::validatePage()
on the currentPage()
.
When possible, it is usually better style to disable the Next or Finish button (by specifying mandatory fields
or by reimplementing QWizardPage::isComplete()
) than to reimplement validateCurrentPage()
