527 \class QMessageBox -

528 -

529 \brief The QMessageBox class provides a modal dialog for informing -

530 the user or for asking the user a question and receiving an answer. -

531 -

532 \ingroup standard-dialogs -

533 \inmodule QtWidgets -

534 -

535 A message box displays a primary \l{QMessageBox::text}{text} to -

536 alert the user to a situation, an \l{QMessageBox::informativeText} -

537 {informative text} to further explain the alert or to ask the user -

538 a question, and an optional \l{QMessageBox::detailedText} -

539 {detailed text} to provide even more data if the user requests -

540 it. A message box can also display an \l{QMessageBox::icon} {icon} -

541 and \l{QMessageBox::standardButtons} {standard buttons} for -

542 accepting a user response. -

543 -

544 Two APIs for using QMessageBox are provided, the property-based -

545 API, and the static functions. Calling one of the static functions -

546 is the simpler approach, but it is less flexible than using the -

547 property-based API, and the result is less informative. Using the -

548 property-based API is recommended. -

549 -

550 \section1 The Property-based API -

551 -

552 To use the property-based API, construct an instance of -

553 QMessageBox, set the desired properties, and call exec() to show -

554 the message. The simplest configuration is to set only the -

555 \l{QMessageBox::text} {message text} property. -

556 -

557 \snippet code/src_gui_dialogs_qmessagebox.cpp 5 -

558 -

559 The user must click the \uicontrol{OK} button to dismiss the message -

560 box. The rest of the GUI is blocked until the message box is -

561 dismissed. -

562 -

563 \image msgbox1.png -

564 -

565 A better approach than just alerting the user to an event is to -

566 also ask the user what to do about it. Store the question in the -

567 \l{QMessageBox::informativeText} {informative text} property, and -

568 set the \l{QMessageBox::standardButtons} {standard buttons} -

569 property to the set of buttons you want as the set of user -

570 responses. The buttons are specified by combining values from -

571 StandardButtons using the bitwise OR operator. The display order -

572 for the buttons is platform-dependent. For example, on Windows, -

573 \uicontrol{Save} is displayed to the left of \uicontrol{Cancel}, whereas on -

574 Mac OS, the order is reversed. -

575 -

576 Mark one of your standard buttons to be your -

577 \l{QMessageBox::defaultButton()} {default button}. -

578 -

579 \snippet code/src_gui_dialogs_qmessagebox.cpp 6 -

580 -

581 This is the approach recommended in the -

582 \l{http://developer.apple.com/library/mac/documentation/UserExperience/Conceptual/AppleHIGuidelines/Windows/Windows.html#//apple_ref/doc/uid/20000961-BABCAJID} -

583 {\macos Guidelines}. Similar guidelines apply for the other -

584 platforms, but note the different ways the -

585 \l{QMessageBox::informativeText} {informative text} is handled for -

586 different platforms. -

587 -

588 \image msgbox2.png -

589 -

590 The exec() slot returns the StandardButtons value of the button -

591 that was clicked. -

592 -

593 \snippet code/src_gui_dialogs_qmessagebox.cpp 7 -

594 -

595 To give the user more information to help him answer the question, -

596 set the \l{QMessageBox::detailedText} {detailed text} property. If -

597 the \l{QMessageBox::detailedText} {detailed text} property is set, -

598 the \uicontrol{Show Details...} button will be shown. -

599 -

600 \image msgbox3.png -

601 -

602 Clicking the \uicontrol{Show Details...} button displays the detailed text. -

603 -

604 \image msgbox4.png -

605 -

606 \section2 Rich Text and the Text Format Property -

607 -

608 The \l{QMessageBox::detailedText} {detailed text} property is -

609 always interpreted as plain text. The \l{QMessageBox::text} {main -

610 text} and \l{QMessageBox::informativeText} {informative text} -

611 properties can be either plain text or rich text. These strings -

612 are interpreted according to the setting of the -

613 \l{QMessageBox::textFormat} {text format} property. The default -

614 setting is \l{Qt::AutoText} {auto-text}. -

615 -

616 Note that for some plain text strings containing XML -

617 meta-characters, the auto-text \l{Qt::mightBeRichText()} {rich -

618 text detection test} may fail causing your plain text string to be -

619 interpreted incorrectly as rich text. In these rare cases, use -

620 Qt::convertFromPlainText() to convert your plain text string to a -

621 visually equivalent rich text string, or set the -

622 \l{QMessageBox::textFormat} {text format} property explicitly with -

623 setTextFormat(). -

624 -

625 \section2 Severity Levels and the Icon and Pixmap Properties -

626 -

627 QMessageBox supports four predefined message severity levels, or message -

628 types, which really only differ in the predefined icon they each show. -

629 Specify one of the four predefined message types by setting the -

630 \l{QMessageBox::icon}{icon} property to one of the -

631 \l{QMessageBox::Icon}{predefined icons}. The following rules are -

632 guidelines: -

633 -

634 \table -

635 \row -

636 \li \image qmessagebox-quest.png -

637 \li \l Question -

638 \li For asking a question during normal operations. -

639 \row -

640 \li \image qmessagebox-info.png -

641 \li \l Information -

642 \li For reporting information about normal operations. -

643 \row -

644 \li \image qmessagebox-warn.png -

645 \li \l Warning -

646 \li For reporting non-critical errors. -

647 \row -

648 \li \image qmessagebox-crit.png -

649 \li \l Critical -

650 \li For reporting critical errors. -

651 \endtable -

652 -

653 \l{QMessageBox::Icon}{Predefined icons} are not defined by QMessageBox, but -

654 provided by the style. The default value is \l{QMessageBox::NoIcon} -

655 {No Icon}. The message boxes are otherwise the same for all cases. When -

656 using a standard icon, use the one recommended in the table, or use the -

657 one recommended by the style guidelines for your platform. If none of the -

658 standard icons is right for your message box, you can use a custom icon by -

659 setting the \l{QMessageBox::iconPixmap}{icon pixmap} property instead of -

660 setting the \l{QMessageBox::icon}{icon} property. -

661 -

662 In summary, to set an icon, use \e{either} setIcon() for one of the -

663 standard icons, \e{or} setIconPixmap() for a custom icon. -

664 -

665 \section1 The Static Functions API -

666 -

667 Building message boxes with the static functions API, although -

668 convenient, is less flexible than using the property-based API, -

669 because the static function signatures lack parameters for setting -

670 the \l{QMessageBox::informativeText} {informative text} and -

671 \l{QMessageBox::detailedText} {detailed text} properties. One -

672 work-around for this has been to use the \c{title} parameter as -

673 the message box main text and the \c{text} parameter as the -

674 message box informative text. Because this has the obvious -

675 drawback of making a less readable message box, platform -

676 guidelines do not recommend it. The \e{Microsoft Windows User -

677 Interface Guidelines} recommend using the -

678 \l{QCoreApplication::applicationName} {application name} as the -

679 \l{QMessageBox::setWindowTitle()} {window's title}, which means -

680 that if you have an informative text in addition to your main -

681 text, you must concatenate it to the \c{text} parameter. -

682 -

683 Note that the static function signatures have changed with respect -

684 to their button parameters, which are now used to set the -

685 \l{QMessageBox::standardButtons} {standard buttons} and the -

686 \l{QMessageBox::defaultButton()} {default button}. -

687 -

688 Static functions are available for creating information(), -

689 question(), warning(), and critical() message boxes. -

690 -

691 \snippet code/src_gui_dialogs_qmessagebox.cpp 0 -

692 -

693 The \l{dialogs/standarddialogs}{Standard Dialogs} example shows -

694 how to use QMessageBox and the other built-in Qt dialogs. -

695 -

696 \section1 Advanced Usage -

697 -

698 If the \l{QMessageBox::StandardButtons} {standard buttons} are not -

699 flexible enough for your message box, you can use the addButton() -

700 overload that takes a text and a ButtonRole to add custom -

701 buttons. The ButtonRole is used by QMessageBox to determine the -

702 ordering of the buttons on screen (which varies according to the -

703 platform). You can test the value of clickedButton() after calling -

704 exec(). For example, -

705 -

706 \snippet code/src_gui_dialogs_qmessagebox.cpp 2 -

707 -

708 \section1 Default and Escape Keys -

709 -

710 The default button (i.e., the button activated when \uicontrol Enter is -

711 pressed) can be specified using setDefaultButton(). If a default -

712 button is not specified, QMessageBox tries to find one based on -

713 the \l{ButtonRole} {button roles} of the buttons used in the -

714 message box. -

715 -

716 The escape button (the button activated when \uicontrol Esc is pressed) -

717 can be specified using setEscapeButton(). If an escape button is -

718 not specified, QMessageBox tries to find one using these rules: -

719 -

720 \list 1 -

721 -

722 \li If there is only one button, it is the button activated when -

723 \uicontrol Esc is pressed. -

724 -

725 \li If there is a \l Cancel button, it is the button activated when -

726 \uicontrol Esc is pressed. -

727 -

728 \li If there is exactly one button having either -

729 \l{QMessageBox::RejectRole} {the Reject role} or the -

730 \l{QMessageBox::NoRole} {the No role}, it is the button -

731 activated when \uicontrol Esc is pressed. -

732 -

733 \endlist -

734 -

735 When an escape button can't be determined using these rules, -

736 pressing \uicontrol Esc has no effect. -

737 -
