445 | \class QMessageBox
|
---|
446 |
|
---|
447 | \brief The QMessageBox class provides a modal dialog for informing
|
---|
448 | the user or for asking the user a question and receiving an answer.
|
---|
449 |
|
---|
450 | \ingroup standard-dialogs
|
---|
451 |
|
---|
452 |
|
---|
453 | A message box displays a primary \l{QMessageBox::text}{text} to
|
---|
454 | alert the user to a situation, an \l{QMessageBox::informativeText}
|
---|
455 | {informative text} to further explain the alert or to ask the user
|
---|
456 | a question, and an optional \l{QMessageBox::detailedText}
|
---|
457 | {detailed text} to provide even more data if the user requests
|
---|
458 | it. A message box can also display an \l{QMessageBox::icon} {icon}
|
---|
459 | and \l{QMessageBox::standardButtons} {standard buttons} for
|
---|
460 | accepting a user response.
|
---|
461 |
|
---|
462 | Two APIs for using QMessageBox are provided, the property-based
|
---|
463 | API, and the static functions. Calling one of the static functions
|
---|
464 | is the simpler approach, but it is less flexible than using the
|
---|
465 | property-based API, and the result is less informative. Using the
|
---|
466 | property-based API is recommended.
|
---|
467 |
|
---|
468 | \section1 The Property-based API
|
---|
469 |
|
---|
470 | To use the property-based API, construct an instance of
|
---|
471 | QMessageBox, set the desired properties, and call exec() to show
|
---|
472 | the message. The simplest configuration is to set only the
|
---|
473 | \l{QMessageBox::text} {message text} property.
|
---|
474 |
|
---|
475 | \snippet doc/src/snippets/code/src_gui_dialogs_qmessagebox.cpp 5
|
---|
476 |
|
---|
477 | The user must click the \gui{OK} button to dismiss the message
|
---|
478 | box. The rest of the GUI is blocked until the message box is
|
---|
479 | dismissed.
|
---|
480 |
|
---|
481 | \image msgbox1.png
|
---|
482 |
|
---|
483 | A better approach than just alerting the user to an event is to
|
---|
484 | also ask the user what to do about it. Store the question in the
|
---|
485 | \l{QMessageBox::informativeText} {informative text} property, and
|
---|
486 | set the \l{QMessageBox::standardButtons} {standard buttons}
|
---|
487 | property to the set of buttons you want as the set of user
|
---|
488 | responses. The buttons are specified by combining values from
|
---|
489 | StandardButtons using the bitwise OR operator. The display order
|
---|
490 | for the buttons is platform-dependent. For example, on Windows,
|
---|
491 | \gui{Save} is displayed to the left of \gui{Cancel}, whereas on
|
---|
492 | Mac OS, the order is reversed.
|
---|
493 |
|
---|
494 | Mark one of your standard buttons to be your
|
---|
495 | \l{QMessageBox::defaultButton()} {default button}.
|
---|
496 |
|
---|
497 | \snippet doc/src/snippets/code/src_gui_dialogs_qmessagebox.cpp 6
|
---|
498 |
|
---|
499 | This is the approach recommended in the
|
---|
500 | \l{http://developer.apple.com/documentation/UserExperience/Conceptual/AppleHIGuidelines/XHIGWindows/chapter_18_section_7.html}
|
---|
501 | {Mac OS X Guidlines}. Similar guidlines apply for the other
|
---|
502 | platforms, but note the different ways the
|
---|
503 | \l{QMessageBox::informativeText} {informative text} is handled for
|
---|
504 | different platforms.
|
---|
505 |
|
---|
506 | \image msgbox2.png
|
---|
507 |
|
---|
508 | The exec() slot returns the StandardButtons value of the button
|
---|
509 | that was clicked.
|
---|
510 |
|
---|
511 | \snippet doc/src/snippets/code/src_gui_dialogs_qmessagebox.cpp 7
|
---|
512 |
|
---|
513 | To give the user more information to help him answer the question,
|
---|
514 | set the \l{QMessageBox::detailedText} {detailed text} property. If
|
---|
515 | the \l{QMessageBox::detailedText} {detailed text} property is set,
|
---|
516 | the \gui{Show Details...} button will be shown.
|
---|
517 |
|
---|
518 | \image msgbox3.png
|
---|
519 |
|
---|
520 | Clicking the \gui{Show Details...} button displays the detailed text.
|
---|
521 |
|
---|
522 | \image msgbox4.png
|
---|
523 |
|
---|
524 | \section2 Rich Text and the Text Format Property
|
---|
525 |
|
---|
526 | The \l{QMessageBox::detailedText} {detailed text} property is
|
---|
527 | always interpreted as plain text. The \l{QMessageBox::text} {main
|
---|
528 | text} and \l{QMessageBox::informativeText} {informative text}
|
---|
529 | properties can be either plain text or rich text. These strings
|
---|
530 | are interpreted according to the setting of the
|
---|
531 | \l{QMessageBox::textFormat} {text format} property. The default
|
---|
532 | setting is \l{Qt::AutoText} {auto-text}.
|
---|
533 |
|
---|
534 | Note that for some plain text strings containing XML
|
---|
535 | meta-characters, the auto-text \l{Qt::mightBeRichText()} {rich
|
---|
536 | text detection test} may fail causing your plain text string to be
|
---|
537 | interpreted incorrectly as rich text. In these rare cases, use
|
---|
538 | Qt::convertFromPlainText() to convert your plain text string to a
|
---|
539 | visually equivalent rich text string, or set the
|
---|
540 | \l{QMessageBox::textFormat} {text format} property explicitly with
|
---|
541 | setTextFormat().
|
---|
542 |
|
---|
543 | \section2 Severity Levels and the Icon and Pixmap Properties
|
---|
544 |
|
---|
545 | QMessageBox supports four predefined message severity levels, or message
|
---|
546 | types, which really only differ in the predefined icon they each show.
|
---|
547 | Specify one of the four predefined message types by setting the
|
---|
548 | \l{QMessageBox::icon}{icon} property to one of the
|
---|
549 | \l{QMessageBox::Icon}{predefined icons}. The following rules are
|
---|
550 | guidelines:
|
---|
551 |
|
---|
552 | \table
|
---|
553 | \row
|
---|
554 | \o \img qmessagebox-quest.png
|
---|
555 | \o \l Question
|
---|
556 | \o For asking a question during normal operations.
|
---|
557 | \row
|
---|
558 | \o \img qmessagebox-info.png
|
---|
559 | \o \l Information
|
---|
560 | \o For reporting information about normal operations.
|
---|
561 | \row
|
---|
562 | \o \img qmessagebox-warn.png
|
---|
563 | \o \l Warning
|
---|
564 | \o For reporting non-critical errors.
|
---|
565 | \row
|
---|
566 | \o \img qmessagebox-crit.png
|
---|
567 | \o \l Critical
|
---|
568 | \o For reporting critical errors.
|
---|
569 | \endtable
|
---|
570 |
|
---|
571 | \l{QMessageBox::Icon}{Predefined icons} are not defined by QMessageBox, but
|
---|
572 | provided by the style. The default value is \l{QMessageBox::NoIcon}
|
---|
573 | {No Icon}. The message boxes are otherwise the same for all cases. When
|
---|
574 | using a standard icon, use the one recommended in the table, or use the
|
---|
575 | one recommended by the style guidelines for your platform. If none of the
|
---|
576 | standard icons is right for your message box, you can use a custom icon by
|
---|
577 | setting the \l{QMessageBox::iconPixmap}{icon pixmap} property instead of
|
---|
578 | setting the \l{QMessageBox::icon}{icon} property.
|
---|
579 |
|
---|
580 | In summary, to set an icon, use \e{either} setIcon() for one of the
|
---|
581 | standard icons, \e{or} setIconPixmap() for a custom icon.
|
---|
582 |
|
---|
583 | \section1 The Static Functions API
|
---|
584 |
|
---|
585 | Building message boxes with the static functions API, although
|
---|
586 | convenient, is less flexible than using the property-based API,
|
---|
587 | because the static function signatures lack parameters for setting
|
---|
588 | the \l{QMessageBox::informativeText} {informative text} and
|
---|
589 | \l{QMessageBox::detailedText} {detailed text} properties. One
|
---|
590 | work-around for this has been to use the \c{title} parameter as
|
---|
591 | the message box main text and the \c{text} parameter as the
|
---|
592 | message box informative text. Because this has the obvious
|
---|
593 | drawback of making a less readable message box, platform
|
---|
594 | guidelines do not recommend it. The \e{Microsoft Windows User
|
---|
595 | Interface Guidelines} recommend using the
|
---|
596 | \l{QCoreApplication::applicationName} {application name} as the
|
---|
597 | \l{QMessageBox::setWindowTitle()} {window's title}, which means
|
---|
598 | that if you have an informative text in addition to your main
|
---|
599 | text, you must concatenate it to the \c{text} parameter.
|
---|
600 |
|
---|
601 | Note that the static function signatures have changed with respect
|
---|
602 | to their button parameters, which are now used to set the
|
---|
603 | \l{QMessageBox::standardButtons} {standard buttons} and the
|
---|
604 | \l{QMessageBox::defaultButton()} {default button}.
|
---|
605 |
|
---|
606 | Static functions are available for creating information(),
|
---|
607 | question(), warning(), and critical() message boxes.

|
---|
611 | The \l{dialogs/standarddialogs}{Standard Dialogs} example shows
|
---|
612 | how to use QMessageBox and the other built-in Qt dialogs.
|
---|
613 |
|
---|
614 | \section1 Advanced Usage
|
---|
615 |
|
---|
616 | If the \l{QMessageBox::StandardButtons} {standard buttons} are not
|
---|
617 | flexible enough for your message box, you can use the addButton()
|
---|
618 | overload that takes a text and a ButtonRoleto to add custom
|
---|
619 | buttons. The ButtonRole is used by QMessageBox to determine the
|
---|
620 | ordering of the buttons on screen (which varies according to the
|
---|
621 | platform). You can test the value of clickedButton() after calling
|
---|
622 | exec(). For example,
|
---|
623 |
|
---|
624 | \snippet doc/src/snippets/code/src_gui_dialogs_qmessagebox.cpp 2
|
---|
625 |
|
---|
626 | \section1 Default and Escape Keys
|
---|
627 |
|
---|
628 | The default button (i.e., the button activated when \key Enter is
|
---|
629 | pressed) can be specified using setDefaultButton(). If a default
|
---|
630 | button is not specified, QMessageBox tries to find one based on
|
---|
631 | the \l{ButtonRole} {button roles} of the buttons used in the
|
---|
632 | message box.
|
---|
633 |
|
---|
634 | The escape button (the button activated when \key Esc is pressed)
|
---|
635 | can be specified using setEscapeButton(). If an escape button is
|
---|
636 | not specified, QMessageBox tries to find one using these rules:
|
---|
637 |
|
---|
638 | \list 1
|
---|
639 |
|
---|
640 | \o If there is only one button, it is the button activated when
|
---|
641 | \key Esc is pressed.
|
---|
642 |
|
---|
643 | \o If there is a \l Cancel button, it is the button activated when
|
---|
644 | \key Esc is pressed.
|
---|
645 |
|
---|
646 | \o If there is exactly one button having either
|
---|
647 | \l{QMessageBox::RejectRole} {the Reject role} or the
|
---|
648 | \l{QMessageBox::NoRole} {the No role}, it is the button
|
---|
649 | activated when \key Esc is pressed.
|
---|
650 |
|
---|
651 | \endlist
|
---|
652 |
|
---|
653 | When an escape button can't be determined using these rules,
|
---|
654 | pressing \key Esc has no effect.
