QDialogs may be + modal or modeless. QDialogs can + provide a \link #return return + value\endlink, and they can have \link #default default + buttons\endlink. QDialogs can also have a QSizeGrip in their + lower-right corner, using setSizeGripEnabled(). + + Note that QDialog (an any other widget that has type Qt::Dialog) uses + the parent widget slightly differently from other classes in Qt. A + dialog is always a top-level widget, but if it has a parent, its + default location is centered on top of the parent's top-level widget + (if it is not top-level itself). It will also share the parent's + taskbar entry. + + Use the overload of the QWidget::setParent() function to change + the ownership of a QDialog widget. This function allows you to + explicitly set the window flags of the reparented widget; using + the overloaded function will clear the window flags specifying the + window-system properties for the widget (in particular it will + reset the Qt::Dialog flag). + + \section1 Modal Dialogs + + A \bold{modal} dialog is a dialog that blocks input to other + visible windows in the same application. Dialogs that are used to + request a file name from the user or that are used to set + application preferences are usually modal. Dialogs can be + \l{Qt::ApplicationModal}{application modal} (the default) or + \l{Qt::WindowModal}{window modal}. + + When an application modal dialog is opened, the user must finish + interacting with the dialog and close it before they can access + any other window in the application. Window modal dialogs only + block access to the window associated with the dialog, allowing + the user to continue to use other windows in an application. + + The most common way to display a modal dialog is to call its + exec() function. When the user closes the dialog, exec() will + provide a useful \link #return return value\endlink. Typically, + to get the dialog to close and return the appropriate value, we + connect a default button, e.g. \gui OK, to the accept() slot and a + \gui Cancel button to the reject() slot. + Alternatively you can call the done() slot with \c Accepted or + \c Rejected. + + An alternative is to call setModal(true) or setWindowModality(), + then show(). Unlike exec(), show() returns control to the caller + immediately. Calling setModal(true) is especially useful for + progress dialogs, where the user must have the ability to interact + with the dialog, e.g. to cancel a long running operation. If you + use show() and setModal(true) together to perform a long operation, + you must call QApplication::processEvents() periodically during + processing to enable the user to interact with the dialog. (See + QProgressDialog.) + + \section1 Modeless Dialogs + + A \bold{modeless} dialog is a dialog that operates + independently of other windows in the same application. Find and + replace dialogs in word-processors are often modeless to allow the + user to interact with both the application's main window and with + the dialog. + + Modeless dialogs are displayed using show(), which returns control + to the caller immediately. + + If you invoke the \l{QWidget::show()}{show()} function after hiding + a dialog, the dialog will be displayed in its original position. This is + because the window manager decides the position for windows that + have not been explicitly placed by the programmer. To preserve the + position of a dialog that has been moved by the user, save its position + in your \l{QWidget::closeEvent()}{closeEvent()} handler and then + move the dialog to that position, before showing it again. + + \target default + \section1 Default Button + + A dialog's \e default button is the button that's pressed when the + user presses Enter (Return). This button is used to signify that + the user accepts the dialog's settings and wants to close the + dialog. Use QPushButton::setDefault(), QPushButton::isDefault() + and QPushButton::autoDefault() to set and control the dialog's + default button. + + \target escapekey + \section1 Escape Key + + If the user presses the Esc key in a dialog, QDialog::reject() + will be called. This will cause the window to close: The \link + QCloseEvent close event \endlink cannot be \link + QCloseEvent::ignore() ignored \endlink. + + \section1 Extensibility + + Extensibility is the ability to show the dialog in two ways: a + partial dialog that shows the most commonly used options, and a + full dialog that shows all the options. Typically an extensible + dialog will initially appear as a partial dialog, but with a + \gui More toggle button. If the user presses the \gui More button down, + the dialog is expanded. The \l{Extension Example} shows how to achieve + extensible dialogs using Qt. + + \target return + \section1 Return Value (Modal Dialogs) + + Modal dialogs are often used in situations where a return value is + required, e.g. to indicate whether the user pressed \gui OK or + \gui Cancel. A dialog can be closed by calling the accept() or the + reject() slots, and exec() will return \c Accepted or \c Rejected + as appropriate. The exec() call returns the result of the dialog. + The result is also available from result() if the dialog has not + been destroyed. + + In order to modify your dialog's close behavior, you can reimplement + the functions accept(), reject() or done(). The + \l{QWidget::closeEvent()}{closeEvent()} function should only be + reimplemented to preserve the dialog's position or to override the + standard close or reject behavior. + + \target examples + \section1 Code Examples + + A modal dialog: + + \snippet doc/src/snippets/dialogs/dialogs.cpp 1 + + A modeless dialog: + + \snippet doc/src/snippets/dialogs/dialogs.cpp 0 + + \sa QDialogButtonBox, QTabWidget, QWidget, QProgressDialog, + {fowler}{GUI Design Handbook: Dialogs, Standard}, {Extension Example}, + {Standard Dialogs Example} +*/ + +/*! \enum QDialog::DialogCode + + The value returned by a modal dialog. + + \value Accepted + \value Rejected +*/ + +/*! + \property QDialog::sizeGripEnabled + \brief whether the size grip is enabled + + A QSizeGrip is placed in the bottom-right corner of the dialog when this + property is enabled.

The cache is + automatically kept up to date using the QFileSystemWatcher. + + QFileSystemModel can be accessed using the standard interface provided by + QAbstractItemModel, but it also provides some convenience functions that are + specific to a directory model. + The fileInfo(), isDir(), name(), and path() functions provide information + about the underlying files and directories related to items in the model. + Directories can be created and removed using mkdir(), rmdir(). + + \note QFileSystemModel requires an instance of a GUI application. + + \sa {Model Classes} +*/ + +/*! + \fn bool QFileSystemModel::rmdir(const QModelIndex &index) const + + Removes the directory corresponding to the model item \a index in the + file system model and \bold{deletes the corresponding directory from the + file system}, returning true if successful.

A message box can also display an \l{QMessageBox::icon} {icon} + and \l{QMessageBox::standardButtons} {standard buttons} for + accepting a user response. + + Two APIs for using QMessageBox are provided, the property-based + API, and the static functions. Calling one of the static functions + is the simpler approach, but it is less flexible than using the + property-based API, and the result is less informative. Using the + property-based API is recommended. + + \section1 The Property-based API + + To use the property-based API, construct an instance of + QMessageBox, set the desired properties, and call exec() to show + the message. The simplest configuration is to set only the + \l{QMessageBox::text} {message text} property. + + \snippet doc/src/snippets/code/src_gui_dialogs_qmessagebox.cpp 5 + + The user must click the \gui{OK} button to dismiss the message + box. The rest of the GUI is blocked until the message box is + dismissed. + + \image msgbox1.png + + A better approach than just alerting the user to an event is to + also ask the user what to do about it. Store the question in the + \l{QMessageBox::informativeText} {informative text} property, and + set the \l{QMessageBox::standardButtons} {standard buttons} + property to the set of buttons you want as the set of user + responses. The buttons are specified by combining values from + StandardButtons using the bitwise OR operator. The display order + for the buttons is platform-dependent. For example, on Windows, + \gui{Save} is displayed to the left of \gui{Cancel}, whereas on + Mac OS, the order is reversed. + + Mark one of your standard buttons to be your + \l{QMessageBox::defaultButton()} {default button}. + + \snippet doc/src/snippets/code/src_gui_dialogs_qmessagebox.cpp 6 + + This is the approach recommended in the + \l{http://developer.apple.com/documentation/UserExperience/Conceptual/AppleHIGuidelines/XHIGWindows/chapter_18_section_7.html} + {Mac OS X Guidlines}. Similar guidlines apply for the other + platforms, but note the different ways the + \l{QMessageBox::informativeText} {informative text} is handled for + different platforms. + + \image msgbox2.png + + The exec() slot returns the StandardButtons value of the button + that was clicked. + + \snippet doc/src/snippets/code/src_gui_dialogs_qmessagebox.cpp 7 + + To give the user more information to help him answer the question, + set the \l{QMessageBox::detailedText} {detailed text} property. If + the \l{QMessageBox::detailedText} {detailed text} property is set, + the \gui{Show Details...} button will be shown. + + \image msgbox3.png + + Clicking the \gui{Show Details...} button displays the detailed text. + + \image msgbox4.png + + \section2 Rich Text and the Text Format Property + + The \l{QMessageBox::detailedText} {detailed text} property is + always interpreted as plain text. The \l{QMessageBox::text} {main + text} and \l{QMessageBox::informativeText} {informative text} + properties can be either plain text or rich text. These strings + are interpreted according to the setting of the + \l{QMessageBox::textFormat} {text format} property. The default + setting is \l{Qt::AutoText} {auto-text}. + + Note that for some plain text strings containing XML + meta-characters, the auto-text \l{Qt::mightBeRichText()} {rich + text detection test} may fail causing your plain text string to be + interpreted incorrectly as rich text. In these rare cases, use + Qt::convertFromPlainText() to convert your plain text string to a + visually equivalent rich text string, or set the + \l{QMessageBox::textFormat} {text format} property explicitly with + setTextFormat(). + + \section2 Severity Levels and the Icon and Pixmap Properties + + QMessageBox supports four predefined message severity levels, or + message types, which really only differ in the predefined icon + they each show. Specify one of the four predefined message types + by setting the \l{QMessageBox::icon} {icon} property to one of the + \l{QMessageBox::Icon} {predefined Icons}. The following rules are + guidelines: + + \table + \row + \o \img qmessagebox-quest.png + \o \l Question + \o For asking a question during normal operations. + \row + \o \img qmessagebox-info.png + \o \l Information + \o For reporting information about normal operations. + \row + \o \img qmessagebox-warn.png + \o \l Warning + \o For reporting non-critical errors. + \row + \o \img qmessagebox-crit.png + \o \l Critical + \o For reporting critical errors. + \endtable + + The default value is \l{QMessageBox::NoIcon} {No Icon}. The + message boxes are otherwise the same for all cases. When using a + standard icon, use the one recommended in the table, or use the + one recommended by the style guidelines for your platform. If none + of the standard icons is right for your message box, you can use a + custom icon by setting the \l{QMessageBox::iconPixmap} {icon + pixmap} property instead of setting the \l{QMessageBox::icon} + {icon} property. + + In summary, to set an icon, use \e{either} setIcon() for one of + the standard icons, \e{or} setIconPixmap() for a custom icon. + + \section1 The Static Functions API + + Building message boxes with the static functions API, although + convenient, is less flexible than using the property-based API, + because the static function signatures lack parameters for setting + the \l{QMessageBox::informativeText} {informative text} and + \l{QMessageBox::detailedText} {detailed text} properties. One + work-around for this has been to use the \c{title} parameter as + the message box main text and the \c{text} parameter as the + message box informative text. Because this has the obvious + drawback of making a less readable message box, platform + guidelines do not recommend it. The \e{Microsoft Windows User + Interface Guidelines} recommend using the + \l{QCoreApplication::applicationName} {application name} as the + \l{QMessageBox::setWindowTitle()} {window's title}, which means + that if you have an informative text in addition to your main + text, you must concatenate it to the \c{text} parameter. + + Note that the static function signatures have changed with respect + to their button parameters, which are now used to set the + \l{QMessageBox::standardButtons} {standard buttons} and the + \l{QMessageBox::defaultButton()} {default button}. + + Static functions are available for creating information(), + question(), warning(), and critical() message boxes. + + \snippet doc/src/snippets/code/src_gui_dialogs_qmessagebox.cpp 0 + + The \l{dialogs/standarddialogs}{Standard Dialogs} example shows + how to use QMessageBox and the other built-in Qt dialogs. + + \section1 Advanced Usage + + If the \l{QMessageBox::StandardButtons} {standard buttons} are not + flexible enough for your message box, you can use the addButton() + overload that takes a text and a ButtonRoleto to add custom + buttons. The ButtonRole is used by QMessageBox to determine the + ordering of the buttons on screen (which varies according to the + platform). You can test the value of clickedButton() after calling + exec(). For example, + + \snippet doc/src/snippets/code/src_gui_dialogs_qmessagebox.cpp 2 + + \section1 Default and Escape Keys + + The default button (i.e., the button activated when \key Enter is + pressed) can be specified using setDefaultButton(). If a default + button is not specified, QMessageBox tries to find one based on + the \l{ButtonRole} {button roles} of the buttons used in the + message box. + + The escape button (the button activated when \key Esc is pressed) + can be specified using setEscapeButton(). If an escape button is + not specified, QMessageBox tries to find one using these rules: + + \list 1 + + \o If there is only one button, it is the button activated when + \key Esc is pressed. + + \o If there is a \l Cancel button, it is the button activated when + \key Esc is pressed. + + \o If there is exactly one button having either + \l{QMessageBox::RejectRole} {the Reject role} or the + \l{QMessageBox::NoRole} {the No role}, it is the button + activated when \key Esc is pressed. + + \endlist + + When an escape button can't be determined using these rules, + pressing \key Esc has no effect. + + \sa QDialogButtonBox, {fowler}{GUI Design Handbook: Message Box}, {Standard Dialogs Example}, {Application Example} +*/ + +/*! + \enum QMessageBox::StandardButton + \since 4.2 + + These enums describe flags for standard buttons.

It can also give the user an opportunity + to abort the operation. + + A common problem with progress dialogs is that it is difficult to know + when to use them; operations take different amounts of time on different + hardware. QProgressDialog offers a solution to this problem: + it estimates the time the operation will take (based on time for + steps), and only shows itself if that estimate is beyond minimumDuration() + (4 seconds by default). + + Use setMinimum() and setMaximum() or the constructor to set the number of + "steps" in the operation and call setValue() as the operation + progresses. The number of steps can be chosen arbitrarily. It can be the + number of files copied, the number of bytes received, the number of + iterations through the main loop of your algorithm, or some other + suitable unit. Progress starts at the value set by setMinimum(), + and the progress dialog shows that the operation has finished when + you call setValue() with the value set by setMaximum() as its argument. + + The dialog automatically resets and hides itself at the end of the + operation. Use setAutoReset() and setAutoClose() to change this + behavior. Note that if you set a new maximum (using setMaximum() or + setRange()) that equals your current value(), the dialog will not + close regardless. + + There are two ways of using QProgressDialog: modal and modeless. + + Compared to a modeless QProgressDialog, a modal QProgressDialog is simpler + to use for the programmer. Do the operation in a loop, call \l setValue() at + intervals, and check for cancellation with wasCanceled(). For example: + + \snippet doc/src/snippets/dialogs/dialogs.cpp 3 + + A modeless progress dialog is suitable for operations that take + place in the background, where the user is able to interact with the + application. Such operations are typically based on QTimer (or + QObject::timerEvent()), QSocketNotifier, or QUrlOperator; or performed + in a separate thread. A QProgressBar in the status bar of your main window + is often an alternative to a modeless progress dialog. + + You need to have an event loop to be running, connect the + canceled() signal to a slot that stops the operation, and call \l + setValue() at intervals. For example: + + \snippet doc/src/snippets/dialogs/dialogs.cpp 4 + \codeline + \snippet doc/src/snippets/dialogs/dialogs.cpp 5 + \codeline + \snippet doc/src/snippets/dialogs/dialogs.cpp 6 + + In both modes the progress dialog may be customized by + replacing the child widgets with custom widgets by using setLabel(), + setBar(), and setCancelButton(). + The functions setLabelText() and setCancelButtonText() + set the texts shown. + + \image plastique-progressdialog.png A progress dialog shown in the Plastique widget style. + + \sa QDialog, QProgressBar, {fowler}{GUI Design Handbook: Progress Indicator}, + {Find Files Example}, {Pixelator Example} +*/ + + +/*! + Constructs a progress dialog. + + Default settings: + \list + \i The label text is empty. + \i The cancel button text is (translated) "Cancel". + \i minimum is 0; + \i maximum is 100 + \endlist + + The \a parent argument is dialog's parent widget.

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: + + \tableofcontents + + \section1 A Trivial Example + + The following example illustrates how to create wizard pages and + add them to a wizard. For more advanced examples, see + \l{dialogs/classwizard}{Class Wizard} and \l{dialogs/licensewizard}{License + Wizard}. + + \snippet examples/dialogs/trivialwizard/trivialwizard.cpp 1 + \snippet examples/dialogs/trivialwizard/trivialwizard.cpp 3 + \dots + \snippet examples/dialogs/trivialwizard/trivialwizard.cpp 4 + \codeline + \snippet examples/dialogs/trivialwizard/trivialwizard.cpp 5 + \snippet examples/dialogs/trivialwizard/trivialwizard.cpp 7 + \dots + \snippet examples/dialogs/trivialwizard/trivialwizard.cpp 8 + \codeline + \snippet examples/dialogs/trivialwizard/trivialwizard.cpp 10 + + \section1 Wizard Look and Feel + + QWizard supports four wizard looks: + + \list + \o ClassicStyle + \o ModernStyle + \o MacStyle + \o AeroStyle + \endlist + + You can explicitly set the look to use using setWizardStyle() + (e.g., if you want the same look on all platforms). + + \table + \header \o ClassicStyle + \o ModernStyle + \o MacStyle + \o AeroStyle + \row \o \inlineimage qtwizard-classic1.png + \o \inlineimage qtwizard-modern1.png + \o \inlineimage qtwizard-mac1.png + \o \inlineimage qtwizard-aero1.png + \row \o \inlineimage qtwizard-classic2.png + \o \inlineimage qtwizard-modern2.png + \o \inlineimage qtwizard-mac2.png + \o \inlineimage qtwizard-aero2.png + \endtable + + 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 \gui 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 \gui 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: + + \snippet examples/dialogs/licensewizard/licensewizard.cpp 29 + + \section1 Elements of a Wizard Page + + Wizards consist of a sequence of \l{QWizardPage}s. At any time, + only one page is shown. A page has the following attributes: + + \list + \o A \l{QWizardPage::}{title}. + \o A \l{QWizardPage::}{subTitle}. + \o A set of pixmaps, which may or may not be honored, depending + on the wizard's style: + \list + \o WatermarkPixmap (used by ClassicStyle and ModernStyle) + \o BannerPixmap (used by ModernStyle) + \o LogoPixmap (used by ClassicStyle and ModernStyle) + \o BackgroundPixmap (used by MacStyle) + \endlist + \endlist + + The diagram belows shows how QWizard renders these attributes, + assuming they are all present and ModernStyle is used: + + \image qtwizard-nonmacpage.png + + When a \l{QWizardPage::}{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 \l{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 (\l{QLabel}s, \l{QLineEdit}s, etc.). + + If the wizard's style is MacStyle, the page looks radically + different: + + \image qtwizard-macpage.png + + The watermark, banner, and logo pixmaps are ignored by the + 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(). + + \target field mechanism + \section1 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: + + \snippet examples/dialogs/classwizard/classwizard.cpp 8 + \dots + \snippet examples/dialogs/classwizard/classwizard.cpp 10 + \snippet examples/dialogs/classwizard/classwizard.cpp 11 + \dots + \snippet examples/dialogs/classwizard/classwizard.cpp 13 + + The above code registers three fields, \c className, \c + baseClass, and \c qobjectMacro, which are associated with three + child widgets. The asterisk (\c *) next to \c className denotes a + mandatory field. + + \target initialize page + The fields of any page are accessible from any other page. For + example: + + \snippet examples/dialogs/classwizard/classwizard.cpp 17 + + Here, we call QWizardPage::field() to access the contents of the + \c className field (which was defined in the \c ClassInfoPage) + and use it to initialize the \c OuputFilePage. The field's + contents is returned as a QVariant. + + When we create a field using 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. + + \target mandatory fields + + If an asterisk (\c *) is appended to the name when the property + is registered, the field is a \e{mandatory field}. When a page has + mandatory fields, the \gui Next and/or \gui Finish buttons are + enabled only when all mandatory fields are filled. + + To consider a field "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 + \l{QLineEdit::hasAcceptableInput()}{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. + + The enabled/disabled state of the \gui Next and/or \gui Finish + buttons is one way to perform validation on the user input. + Another way is to reimplement 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. + + \section1 Creating Linear Wizards + + Most wizards have a linear structure, with page 1 followed by + page 2 and so on until the last page. The \l{dialogs/classwizard}{Class + Wizard} example is such a wizard. With QWizard, linear wizards + are created by instantiating the \l{QWizardPage}s and inserting + them using addPage(). By default, the pages are shown in the + order in which they were added. For example: + + \snippet examples/dialogs/classwizard/classwizard.cpp 0 + \dots + \snippet examples/dialogs/classwizard/classwizard.cpp 2 + + 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 \l{initialize page}{example + above}). + + If the user presses \gui 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 \gui Back button to be non-destructive and keep the + values entered by the user, simply enable the IndependentPages + option. + + \section1 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 \l{dialogs/licensewizard}{License Wizard} example illustrates this. + It provides five wizard pages; depending on which options are + selected, the user can reach different pages. + + \image licensewizard-flow.png + + In complex wizards, pages are identified by IDs. These IDs are + typically defined using an enum. For example: + + \snippet examples/dialogs/licensewizard/licensewizard.h 0 + \dots + \snippet examples/dialogs/licensewizard/licensewizard.h 2 + \dots + \snippet examples/dialogs/licensewizard/licensewizard.h 3 + + The pages are inserted using setPage(), which takes an ID and an + instance of QWizardPage (or of a subclass): + + \snippet examples/dialogs/licensewizard/licensewizard.cpp 1 + \dots + \snippet examples/dialogs/licensewizard/licensewizard.cpp 8 + + 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: + + \snippet examples/dialogs/licensewizard/licensewizard.cpp 18 + \codeline + \snippet examples/dialogs/licensewizard/licensewizard.cpp 23 + \codeline + \snippet examples/dialogs/licensewizard/licensewizard.cpp 24 + \codeline + \snippet examples/dialogs/licensewizard/licensewizard.cpp 25 + \codeline + \snippet examples/dialogs/licensewizard/licensewizard.cpp 26 + + It would also be possible to put all the logic in one place, in a + QWizard::nextId() reimplementation. For example: + + \snippet doc/src/snippets/code/src_gui_dialogs_qwizard.cpp 0 + + 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().

Once a + page is added to the wizard (using QWizard::addPage() or + QWizard::setPage()), wizard() returns a pointer to the + associated QWizard object. + + Page provides five virtual functions that can be reimplemented to + provide custom behavior: + + \list + \o initializePage() is called to initialize the page's contents + when the user clicks the wizard's \gui Next button. If you + want to derive the page's default from what the user entered + on previous pages, this is the function to reimplement. + \o cleanupPage() is called to reset the page's contents when the + user clicks the wizard's \gui Back button. + \o validatePage() validates the page when the user clicks \gui + Next or \gui Finish. It is often used to show an error message + if the user has entered incomplete or invalid information. + \o nextId() returns the ID of the next page. It is useful when + \l{creating non-linear wizards}, which allow different + traversal paths based on the information provided by the user. + \o isComplete() is called to determine whether the \gui Next + and/or \gui Finish button should be enabled or disabled. If + you reimplement isComplete(), also make sure that + completeChanged() is emitted whenever the complete state + changes. + \endlist + + Normally, the \gui Next button and the \gui Finish button of a + wizard are mutually exclusive. If isFinalPage() returns true, \gui + Finish is available; otherwise, \gui Next is available. By + default, isFinalPage() is true only when nextId() returns -1. If + you want to show \gui Next and \gui Final simultaneously for a + page (letting the user perform an "early finish"), call + setFinalPage(true) on that page. For wizards that support early + finishes, you might also want to set the + \l{QWizard::}{HaveNextButtonOnLastPage} and + \l{QWizard::}{HaveFinishButtonOnEarlyPages} options on the + wizard. + + 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 \l{Registering and + Using Fields}{"field" mechanism} that allows you to register a + field (e.g., a QLineEdit) on a page and to access its value from + any page. Fields are global to the entire wizard and make it easy + for any single page to access information stored by another page, + without having to put all the logic in QWizard or having the + pages know explicitly about each other. Fields are registered + using registerField() and can be accessed at any time using + field() and setField(). + + \sa QWizard, {Class Wizard Example}, {License Wizard Example} +*/ + +/*! + Constructs a wizard page with the given \a parent. + + When the page is inserted into a wizard using QWizard::addPage() + or QWizard::setPage(), the parent is automatically set to be the + wizard. + + \sa wizard() +*/ +QWizardPage::QWizardPage(QWidget *parent) + : QWidget(*new QWizardPagePrivate, parent, 0) +{ + connect(this, SIGNAL(completeChanged()), this, SLOT(_q_updateCachedCompleteState())); +} + +/*! + \property QWizardPage::title + \brief the title of the page + + The title is shown by the QWizard, above the actual page.
