[править]

QMessageBox::QMessageBox ( const QString & title, const QString & text, Icon icon, int button0, int button1, int button2, QWidget * parent = 0, Qt::WindowFlags f = Qt::Dialog | Qt::MSWindowsFixedSizeDialogHint )

Constructs a message box with a title, a text, an icon, and up to three buttons.

The icon must be one of the following:

• QMessageBox::NoIcon
• QMessageBox::Question
• QMessageBox::Information
• QMessageBox::Warning
• QMessageBox::Critical

Each button, button0, button1 and button2, can have one of the following values:

• QMessageBox::NoButton
• QMessageBox::Ok
• QMessageBox::Cancel
• QMessageBox::Yes
• QMessageBox::No
• QMessageBox::Abort
• QMessageBox::Retry
• QMessageBox::Ignore
• QMessageBox::YesAll
• QMessageBox::NoAll

Use QMessageBox::NoButton for the later parameters to have fewer than three buttons in your message box. If you don't specify any buttons at all, QMessageBox will provide an Ok button.

One of the buttons can be OR-ed with the QMessageBox::Default flag to make it the default button (clicked when Enter is pressed).

One of the buttons can be OR-ed with the QMessageBox::Escape flag to make it the cancel or close button (clicked when Esc is pressed).

         QMessageBox mb("Application Name",
                        "Hardware failure.\n\nDisk error detected\nDo you want to stop?",
                        QMessageBox::Question,
                        QMessageBox::Yes | QMessageBox::Default,
                        QMessageBox::No | QMessageBox::Escape,
                        QMessageBox::NoButton);
         if (mb.exec() == QMessageBox::No) {
             // try again

If parent is 0, the message box becomes an application-global modal dialog box. If parent is a widget, the message box becomes modal relative to parent.

The parent and f arguments are passed to the QDialog constructor.

See also setWindowTitle(), setText(), and setIcon().

[править]

QString QMessageBox::buttonText ( int button ) const

Returns the text of the message box button button, or an empty string if the message box does not contain the button.

Use button() and QPushButton::text() instead.

See also setButtonText().

[править]

int QMessageBox::critical ( QWidget * parent, const QString & title, const QString & text, int button0, int button1, int button2 = 0 ) [static]

Эта перегруженная функция предоставлена для удобства.

Opens a critical message box with the given title and text. The dialog may have up to three buttons. Each of the button parameters, button0, button1 and button2 may be set to one of the following values:

• QMessageBox::NoButton
• QMessageBox::Ok
• QMessageBox::Cancel
• QMessageBox::Yes
• QMessageBox::No
• QMessageBox::Abort
• QMessageBox::Retry
• QMessageBox::Ignore
• QMessageBox::YesAll
• QMessageBox::NoAll

If you don't want all three buttons, set the last button, or last two buttons to QMessageBox::NoButton.

One button can be OR-ed with QMessageBox::Default, and one button can be OR-ed with QMessageBox::Escape.

Returns the identity ( QMessageBox::Ok, or QMessageBox::No, etc.) of the button that was clicked.

If parent is 0, the message box becomes an application-global modal dialog box. If parent is a widget, the message box becomes modal relative to parent.

See also information(), question(), and warning().

[править]

int QMessageBox::critical ( QWidget * parent, const QString & title, const QString & text, const QString & button0Text, const QString & button1Text = QString(), const QString & button2Text = QString(), int defaultButtonNumber = 0, int escapeButtonNumber = -1 ) [static]

Эта перегруженная функция предоставлена для удобства.

Displays a critical error message box with the given title and text, as well as one, two, or three buttons. Returns the number of the button that was clicked (0, 1 or 2).

button0Text is the text of the first button, and is optional. If button0Text is not supplied, "OK" (translated) will be used. button1Text is the text of the second button, and is optional, and button2Text is the text of the third button, and is optional. defaultButtonNumber (0, 1 or 2) is the index of the default button; pressing Return or Enter is the same as clicking the default button. It defaults to 0 (the first button). escapeButtonNumber is the index of the Escape button; pressing Escape is the same as clicking this button. It defaults to -1; supply 0, 1, or 2 to make pressing Escape equivalent to clicking the relevant button.

If parent is 0, the message box becomes an application-global modal dialog box. If parent is a widget, the message box becomes modal relative to parent.
