531 \class QMessageBox-
532-
533 \brief The QMessageBox class provides a modal dialog for informing-
534 the user or for asking the user a question and receiving an answer.-
535-
536 \ingroup standard-dialogs-
537 \inmodule QtWidgets-
538-
539 A message box displays a primary \l{QMessageBox::text}{text} to-
540 alert the user to a situation, an \l{QMessageBox::informativeText}-
541 {informative text} to further explain the alert or to ask the user-
542 a question, and an optional \l{QMessageBox::detailedText}-
543 {detailed text} to provide even more data if the user requests-
544 it. A message box can also display an \l{QMessageBox::icon} {icon}-
545 and \l{QMessageBox::standardButtons} {standard buttons} for-
546 accepting a user response.-
547-
548 Two APIs for using QMessageBox are provided, the property-based-
549 API, and the static functions. Calling one of the static functions-
550 is the simpler approach, but it is less flexible than using the-
551 property-based API, and the result is less informative. Using the-
552 property-based API is recommended.-
553-
554 \section1 The Property-based API-
555-
556 To use the property-based API, construct an instance of-
557 QMessageBox, set the desired properties, and call exec() to show-
558 the message. The simplest configuration is to set only the-
559 \l{QMessageBox::text} {message text} property.-
560-
561 \snippet code/src_gui_dialogs_qmessagebox.cpp 5-
562-
563 The user must click the \uicontrol{OK} button to dismiss the message-
564 box. The rest of the GUI is blocked until the message box is-
565 dismissed.-
566-
567 \image msgbox1.png-
568-
569 A better approach than just alerting the user to an event is to-
570 also ask the user what to do about it. Store the question in the-
571 \l{QMessageBox::informativeText} {informative text} property, and-
572 set the \l{QMessageBox::standardButtons} {standard buttons}-
573 property to the set of buttons you want as the set of user-
574 responses. The buttons are specified by combining values from-
575 StandardButtons using the bitwise OR operator. The display order-
576 for the buttons is platform-dependent. For example, on Windows,-
577 \uicontrol{Save} is displayed to the left of \uicontrol{Cancel}, whereas on-
578 Mac OS, the order is reversed.-
579-
580 Mark one of your standard buttons to be your-
581 \l{QMessageBox::defaultButton()} {default button}.-
582-
583 \snippet code/src_gui_dialogs_qmessagebox.cpp 6-
584-
585 This is the approach recommended in the-
586 \l{http://developer.apple.com/library/mac/documentation/UserExperience/Conceptual/AppleHIGuidelines/Windows/Windows.html#//apple_ref/doc/uid/20000961-BABCAJID}-
587 {\macos Guidelines}. Similar guidelines apply for the other-
588 platforms, but note the different ways the-
589 \l{QMessageBox::informativeText} {informative text} is handled for-
590 different platforms.-
591-
592 \image msgbox2.png-
593-
594 The exec() slot returns the StandardButtons value of the button-
595 that was clicked.-
596-
597 \snippet code/src_gui_dialogs_qmessagebox.cpp 7-
598-
599 To give the user more information to help him answer the question,-
600 set the \l{QMessageBox::detailedText} {detailed text} property. If-
601 the \l{QMessageBox::detailedText} {detailed text} property is set,-
602 the \uicontrol{Show Details...} button will be shown.-
603-
604 \image msgbox3.png-
605-
606 Clicking the \uicontrol{Show Details...} button displays the detailed text.-
607-
608 \image msgbox4.png-
609-
610 \section2 Rich Text and the Text Format Property-
611-
612 The \l{QMessageBox::detailedText} {detailed text} property is-
613 always interpreted as plain text. The \l{QMessageBox::text} {main-
614 text} and \l{QMessageBox::informativeText} {informative text}-
615 properties can be either plain text or rich text. These strings-
616 are interpreted according to the setting of the-
617 \l{QMessageBox::textFormat} {text format} property. The default-
618 setting is \l{Qt::AutoText} {auto-text}.-
619-
620 Note that for some plain text strings containing XML-
621 meta-characters, the auto-text \l{Qt::mightBeRichText()} {rich-
622 text detection test} may fail causing your plain text string to be-
623 interpreted incorrectly as rich text. In these rare cases, use-
624 Qt::convertFromPlainText() to convert your plain text string to a-
625 visually equivalent rich text string, or set the-
626 \l{QMessageBox::textFormat} {text format} property explicitly with-
627 setTextFormat().-
628-
629 \section2 Severity Levels and the Icon and Pixmap Properties-
630-
631 QMessageBox supports four predefined message severity levels, or message-
632 types, which really only differ in the predefined icon they each show.-
633 Specify one of the four predefined message types by setting the-
634 \l{QMessageBox::icon}{icon} property to one of the-
635 \l{QMessageBox::Icon}{predefined icons}. The following rules are-
636 guidelines:-
637-
638 \table-
639 \row-
640 \li \image qmessagebox-quest.png-
641 \li \l Question-
642 \li For asking a question during normal operations.-
643 \row-
644 \li \image qmessagebox-info.png-
645 \li \l Information-
646 \li For reporting information about normal operations.-
647 \row-
648 \li \image qmessagebox-warn.png-
649 \li \l Warning-
650 \li For reporting non-critical errors.-
651 \row-
652 \li \image qmessagebox-crit.png-
653 \li \l Critical-
654 \li For reporting critical errors.-
655 \endtable-
656-
657 \l{QMessageBox::Icon}{Predefined icons} are not defined by QMessageBox, but-
658 provided by the style. The default value is \l{QMessageBox::NoIcon}-
659 {No Icon}. The message boxes are otherwise the same for all cases. When-
660 using a standard icon, use the one recommended in the table, or use the-
661 one recommended by the style guidelines for your platform. If none of the-
662 standard icons is right for your message box, you can use a custom icon by-
663 setting the \l{QMessageBox::iconPixmap}{icon pixmap} property instead of-
664 setting the \l{QMessageBox::icon}{icon} property.-
665-
666 In summary, to set an icon, use \e{either} setIcon() for one of the-
667 standard icons, \e{or} setIconPixmap() for a custom icon.-
668-
669 \section1 The Static Functions API-
670-
671 Building message boxes with the static functions API, although-
672 convenient, is less flexible than using the property-based API,-
673 because the static function signatures lack parameters for setting-
674 the \l{QMessageBox::informativeText} {informative text} and-
675 \l{QMessageBox::detailedText} {detailed text} properties. One-
676 work-around for this has been to use the \c{title} parameter as-
677 the message box main text and the \c{text} parameter as the-
678 message box informative text. Because this has the obvious-
679 drawback of making a less readable message box, platform-
680 guidelines do not recommend it. The \e{Microsoft Windows User-
681 Interface Guidelines} recommend using the-
682 \l{QCoreApplication::applicationName} {application name} as the-
683 \l{QMessageBox::setWindowTitle()} {window's title}, which means-
684 that if you have an informative text in addition to your main-
685 text, you must concatenate it to the \c{text} parameter.-
686-
687 Note that the static function signatures have changed with respect-
688 to their button parameters, which are now used to set the-
689 \l{QMessageBox::standardButtons} {standard buttons} and the-
690 \l{QMessageBox::defaultButton()} {default button}.-
691-
692 Static functions are available for creating information(),-
693 question(), warning(), and critical() message boxes.-
694-
695 \snippet code/src_gui_dialogs_qmessagebox.cpp 0-
696-
697 The \l{dialogs/standarddialogs}{Standard Dialogs} example shows-
698 how to use QMessageBox and the other built-in Qt dialogs.-
699-
700 \section1 Advanced Usage-
701-
702 If the \l{QMessageBox::StandardButtons} {standard buttons} are not-
703 flexible enough for your message box, you can use the addButton()-
704 overload that takes a text and a ButtonRole to add custom-
705 buttons. The ButtonRole is used by QMessageBox to determine the-
706 ordering of the buttons on screen (which varies according to the-
707 platform). You can test the value of clickedButton() after calling-
708 exec(). For example,-
709-
710 \snippet code/src_gui_dialogs_qmessagebox.cpp 2-
711-
712 \section1 Default and Escape Keys-
713-
714 The default button (i.e., the button activated when \uicontrol Enter is-
715 pressed) can be specified using setDefaultButton(). If a default-
716 button is not specified, QMessageBox tries to find one based on-
717 the \l{ButtonRole} {button roles} of the buttons used in the-
718 message box.-
719-
720 The escape button (the button activated when \uicontrol Esc is pressed)-
721 can be specified using setEscapeButton(). If an escape button is-
722 not specified, QMessageBox tries to find one using these rules:-
723-
724 \list 1-
725-
726 \li If there is only one button, it is the button activated when-
727 \uicontrol Esc is pressed.-
728-
729 \li If there is a \l Cancel button, it is the button activated when-
730 \uicontrol Esc is pressed.-
731-
732 \li If there is exactly one button having either-
733 \l{QMessageBox::RejectRole} {the Reject role} or the-
734 \l{QMessageBox::NoRole} {the No role}, it is the button-
735 activated when \uicontrol Esc is pressed.-
736-
737 \endlist-
738-
739 When an escape button can't be determined using these rules,-
740 pressing \uicontrol Esc has no effect.-
