typedef QMessageBox:: Button

使用 QMessageBox::StandardButton 代替。

成员函数文档编制

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

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

The icon must be one of the following:

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

使用 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

消息框是应用程序模态对话框。

The parent and f 自变量被传递给 QDialog 构造函数。

另请参阅 setWindowTitle (), setText ()，和 setIcon ().

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.

使用 button () 和 QPushButton::text () 代替。

另请参阅 setButtonText ().

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

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:

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 ，或 QMessageBox::No , etc.) of the button that was clicked.

警告： 不要删除 parent during the execution of the dialog. If you want to do this, you should create the dialog yourself using one of the QMessageBox 构造函数。

另请参阅 information (), question ()，和 warning ().

`[static]` 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)

这是重载函数。

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.

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

打开信息消息框采用给定 title 和 text . The dialog may have up to three buttons. Each of the buttons, button0 , button1 and button2 may be set to one of the following values:

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 ，或 QMessageBox::No , etc.) of the button that was clicked.
