Get Started


Before start using, you should specify Language and Background and Foreground. See

  • QModernMessageBox.MainLang

  • QModernMessageBox.GlobalBackground

  • QModernMessageBox.GlobalForeground


            QModernMessageBox.MainLang = new QMetroMessageLang() {
                Ok = "确定",
                Cancel = "取消",
                Abort = "中止(A)",
                Ignore = "忽略(I)",
                No = "否(N)",
                Yes = "是(Y)",
                Retry = "重试(R)"
            QModernMessageBox.GlobalBackground = new SolidColorBrush(Colors.White){Opacity = 0.6};
            QModernMessageBox.GlobalForeground = Brushes.Black;

In this example, The button text of the ModernMessageBox set to Chinese and Background set to white with 60% opacity and Foreground set to Black.

Those setting will use as default in ModernMessageBox.

The default Background in MessageBox is Black, 60% Opacity and the Foreground is White

The default lang is in English

In background setting, you can use a color with not fully solid. In this way, the window will have a Gaussian Blur background in Win10 1803+ In win7/8/8.1 or early version of win10, it will still use the solid color as background. If you don't want a gaussian blur, just set the color solid.

In common cases, you can create a MetroMessageBox with the following code

    QModernMessageBox.Show("The quick brown fox jumps over the lazy dog.", "hello world",QModernMessageBox.QModernMessageBoxButtons.YesNoCancel,ModernMessageboxIcons.Warning);

Or using the QT way:

QModernMessageBox.Warning("The quick brown fox jumps over the lazy dog.", "hello world");


    var msg = new ModernMessageBox("The quick brown fox jumps over the lazy dog.\n", "hello world", ModernMessageboxIcons.Info, "CSharp", "Java",
        "Python") {
        Button1Key = Key.D1,
        Button2Key = Key.D2,
        Button3Key = Key.D3,
        CheckboxText = "Don't show this again",
        CheckboxVisibility = Visibility.Visible,
        TextBoxText = "some staff",
        TextBoxVisibility = Visibility.Visible,


Before start using, you should specify Background and Foreground. See:

  • IndeterminateProgressWindow.GlobalBackground

  • IndeterminateProgressWindow.GlobalForeground


    var win = new IndeterminateProgressWindow("Please wait while we are installing the virus into your computer. . .");
	//Do Some Staff
	await Task.Delay(5000);
	//Change the message the 2nd time
	win.Message = "Done!!!";
