Detailed Description¶
A message box displays a primary
text
to alert the user to a situation, aninformative text
to further explain the alert or to ask the user a question, and an optionaldetailed text
to provide even more data if the user requests it. A message box can also display anicon
andstandard 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 callexec()
to show the message. The simplest configuration is to set only themessage text
property.QMessageBox msgBox; msgBox.setText("The document has been modified."); msgBox.exec();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.
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
informative text
property, and set thestandard buttons
property to the set of buttons you want as the set of user responses. The buttons are specified by combining values fromStandardButtons
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
.QMessageBox msgBox; msgBox.setText("The document has been modified."); msgBox.setInformativeText("Do you want to save your changes?"); msgBox.setStandardButtons(QMessageBox::Save | QMessageBox::Discard | QMessageBox::Cancel); msgBox.setDefaultButton(QMessageBox::Save); int ret = msgBox.exec();This is the approach recommended in the macOS Guidelines . Similar guidelines apply for the other platforms, but note the different ways the
informative text
is handled for different platforms.The
exec()
slot returns theStandardButtons
value of the button that was clicked.switch (ret) { case QMessageBox::Save: // Save was clicked break; case QMessageBox::Discard: // Don't Save was clicked break; case QMessageBox::Cancel: // Cancel was clicked break; default: // should never be reached break; }To give the user more information to help him answer the question, set the
detailed text
property. If thedetailed text
property is set, the Show Details… button will be shown.Clicking the Show Details… button displays the detailed text.
Rich Text and the Text Format Property¶
The
detailed text
property is always interpreted as plain text. Themain text
andinformative text
properties can be either plain text or rich text. These strings are interpreted according to the setting of thetext format
property. The default setting isauto-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, useconvertFromPlainText()
to convert your plain text string to a visually equivalent rich text string, or set thetext format
property explicitly withsetTextFormat()
.
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 theicon
property to one of thepredefined 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.
Predefined icons
are not defined byQMessageBox
, but provided by the style. The default value isNo 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 theicon pixmap
property instead of setting theicon
property.In summary, to set an icon, use either
setIcon()
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
anddetailed text
properties. One work-around for this has been to use thetitle
parameter as the message box main text and thetext
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 theapplication name
as thewindow's title
, which means that if you have an informative text in addition to your main text, you must concatenate it to thetext
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 thedefault button
.Static functions are available for creating
information()
,question()
,warning()
, andcritical()
message boxes.int ret = QMessageBox::warning(this, tr("My Application"), tr("The document has been modified.\n" "Do you want to save your changes?"), QMessageBox::Save | QMessageBox::Discard | QMessageBox::Cancel, QMessageBox::Save);The Standard Dialogs example shows how to use
QMessageBox
and the other built-in Qt dialogs.
Advanced Usage¶
If the
standard buttons
are not flexible enough for your message box, you can use theaddButton()
overload that takes a text and aButtonRole
to add custom buttons. TheButtonRole
is used byQMessageBox
to determine the ordering of the buttons on screen (which varies according to the platform). You can test the value ofclickedButton()
after callingexec()
. For example,QMessageBox msgBox; QPushButton *connectButton = msgBox.addButton(tr("Connect"), QMessageBox::ActionRole); QPushButton *abortButton = msgBox.addButton(QMessageBox::Abort); msgBox.exec(); if (msgBox.clickedButton() == connectButton) { // connect } else if (msgBox.clickedButton() == abortButton) { // abort }
Default and Escape Keys¶
The default button (i.e., the button activated when Enter is pressed) can be specified using
setDefaultButton()
. If a default button is not specified,QMessageBox
tries to find one based on thebutton 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:
If there is only one button, it is the button activated when Esc is pressed.
If there is a
Cancel
button, it is the button activated when Esc is pressed.If there is exactly one button having either
the Reject role
or thethe No role
, it is the button activated when Esc is pressed.When an escape button can’t be determined using these rules, pressing Esc has no effect.

parent –
PySide2.QtWidgets.QWidget
title – str
text – str
Displays a simple about box with title
title
