public class QMessageBox
The QMessageBox class provides a modal dialog for informing the user or for asking the user a question and receiving an answer. A message box displays a primary text
to alert the user to a situation, an informative text
to further explain the alert or to ask the user a question, and an optional detailed text
to provide even more data if the user requests it. A message box can also display an icon
and 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.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 message text
property.Error parsing snippet. The user must click the OK button to dismiss the message box. The rest of the GUI is blocked until the message box is dismissed.
informative text
property, and set the 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, Save is displayed to the left of Cancel, whereas on Mac OS, the order is reversed. Mark one of your standard buttons to be your default button
.Error parsing snippet. This is the approach recommended in the Mac OS X Guidlines. Similar guidlines apply for the other platforms, but note the different ways the informative text
is handled for different platforms.
detailed text
property. If the detailed text
property is set, the Show Details... button will be shown. detailed text
property is always interpreted as plain text. The main text
and informative text
properties can be either plain text or rich text. These strings are interpreted according to the setting of the text format
property. The default setting is auto-text
. Note that for some plain text strings containing XML meta-characters, the auto-text 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 text format
property explicitly with setTextFormat()
.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 icon
property to one of the predefined Icons
. The following rules are guidelines:
![]() | Question | For asking a question during normal operations. |
![]() | Information | For reporting information about normal operations. |
![]() | Warning | For reporting non-critical errors. |
![]() | Critical | For reporting critical errors. |
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 icon pixmap
property instead of setting the icon
property. In summary, to set an icon, use eithersetIcon()
for one of the standard icons, orsetIconPixmap()
for a custom icon.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 informative text
and detailed text
properties. One work-around for this has been to use the title parameter as the message box main text and the 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 Microsoft Windows User Interface Guidelines recommend using the application name
as the window's title, which means that if you have an informative text in addition to your main text, you must concatenate it to the text parameter.
Note that the static function signatures have changed with respect to their button parameters, which are now used to set the standard buttons
and the default button
.
Static functions are available for creating information()
, question()
, warning()
, and critical()
message boxes.
QMessageBox.StandardButtons buttons = new QMessageBox.StandardButtons(); buttons.set(QMessageBox.StandardButton.Save); buttons.set(QMessageBox.StandardButton.Discard); buttons.set(QMessageBox.StandardButton.Cancel); QMessageBox.StandardButton ret = QMessageBox.warning(this, tr("My Application"), tr("The document has been modified.\n" + "Do you want to save your changes?"), buttons, QMessageBox.StandardButton.Save);The Standard Dialogs example shows how to use QMessageBox and the other built-in Qt dialogs.
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, QMessageBox msgBox = new QMessageBox(); QPushButton connectButton = msgBox.addButton(tr("Connect"), QMessageBox.ButtonRole.ActionRole); QPushButton abortButton = msgBox.addButton(QMessageBox.StandardButton.Abort); msgBox.exec(); if (msgBox.clickedButton() == connectButton) { // connect } else if (msgBox.clickedButton() == abortButton) { // abort }
setDefaultButton()
. If a default button is not specified, QMessageBox tries to find one based on the button roles
of the buttons used in the message box. The escape button (the button activated when Esc is pressed) can be specified using setEscapeButton()
. If an escape button is not specified, QMessageBox tries to find one using these rules:
Cancel
button, it is the button activated when Esc is pressed.the Reject role
or the the No role
, it is the button activated when Esc is pressed.QDialogButtonBox
