Detailed Description¶

The PySide.QtGui.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 PySide.QtGui.QMessageBox.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 PySide.QtGui.QMessageBox.icon() and standard buttons for accepting a user response.

Two APIs for using PySide.QtGui.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 PySide.QtGui.QMessageBox , set the desired properties, and call exec() to show the message. The simplest configuration is to set only the message text property.
msgBox = QMessageBox()
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 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 .
msgBox = QMessageBox()
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)
ret = msgBox.exec_()
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.

The exec() slot returns the StandardButtons value of the button that was clicked.
if ret == QMessageBox.Save:
    # Save was clicked
elif ret == QMessageBox.Discard:
    # Don't save was clicked
elif ret == QMessageBox.Cancel:
    # cancel was clicked
else:
    # should never be reached
To give the user more information to help him answer the question, set the detailed text property. If the detailed 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. 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 PySide.QtGui.QMessageBox.setTextFormat() .

Severity Levels and the Icon and Pixmap Properties¶

PySide.QtGui.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 PySide.QtGui.QMessageBox.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.

Predefined icons are not defined by PySide.QtGui.QMessageBox , but provided by the style. The default value is 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 PySide.QtGui.QMessageBox.icon() property.

In summary, to set an icon, use eitherPySide.QtGui.QMessageBox.setIcon() for one of the standard icons, orPySide.QtGui.QMessageBox.setIconPixmap() 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 PySide.QtGui.QMessageBox.information() , PySide.QtGui.QMessageBox.question() , PySide.QtGui.QMessageBox.warning() , and PySide.QtGui.QMessageBox.critical() message boxes.
ret = QMessageBox.warning(self, self.tr("My Application"),
                               self.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 PySide.QtGui.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 the PySide.QtGui.QMessageBox.addButton() overload that takes a text and a ButtonRoleto to add custom buttons. The QMessageBox.ButtonRole is used by PySide.QtGui.QMessageBox to determine the ordering of the buttons on screen (which varies according to the platform). You can test the value of PySide.QtGui.QMessageBox.clickedButton() after calling exec() . For example,
msgBox = QMessageBox()
connectButton = msgBox.addButton(self.tr("Connect"), QMessageBox.ActionRole)
abortButton = msgBox.addButton(QMessageBox.Abort)

msgBox.exec_()

if msgBox.clickedButton() == connectButton:
    # connect
elif msgBox.clickedButton() == abortButton:
    # abort
}

Default and Escape Keys¶

The default button (i.e., the button activated when Enter is pressed) can be specified using PySide.QtGui.QMessageBox.setDefaultButton() . If a default button is not specified, PySide.QtGui.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 PySide.QtGui.QMessageBox.setEscapeButton() . If an escape button is not specified, PySide.QtGui.QMessageBox tries to find one using these rules:

When an escape button can’t be determined using these rules, pressing Esc has no effect.
