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 - - \l{QMessageBox::Icon}{Predefined icons} are not defined by QMessageBox, but - provided by the style. 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.
