地铁MahApps MessageBox主题

Question

也许有人可以告诉我如何将异步消息正确地实现到Metro窗口，使其具有应用程序当前的主题和重音？

从演示示例中提取的代码可以工作，但是主题和重音仍然是默认的：

private async void ClosingApp(object sender, System.ComponentModel.CancelEventArgs e)
    {
        e.Cancel = !_shutdown;
        if (_shutdown) return;
        var mySettings = new MetroDialogSettings()
        {
            AffirmativeButtonText = "Quit",
            NegativeButtonText = "Cancel",
            AnimateShow = true,
            AnimateHide = false
        };
        var result = await this.ShowMessageAsync("Quit application?",
            "Sure you want to quit application?",
            MessageDialogStyle.AffirmativeAndNegative, mySettings);

        _shutdown = result == MessageDialogResult.Affirmative;
        if (_shutdown)
            Application.Current.Shutdown();
    }

当我简单地改变主题：

 private void MenuItem_Click(object sender, RoutedEventArgs e)
    {
        // set the Red accent and dark theme only to the current window
        var theme = ThemeManager.GetAppTheme("BaseDark");
        var accent = ThemeManager.GetAccent("Red");
        ThemeManager.ChangeAppStyle(Application.Current, accent, theme);
    }

我得到默认的白色和蓝色MessageBox。我做错了什么？

Answer 1

我试过你的代码了，它正在工作。我只在一个MenuItem_Click中转换了Button_Click，但这是不相关的。

我得到了黑色的背景和红色退出，如下图所示，在单击“设置”按钮后，iff I关闭了应用程序。

而不是最初的

我有一个标准的Window1.xaml，从

<Controls:MetroWindow x:Class="TestFrontend.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
        Closing="App_Closing"
    Title="Test" Height="600" Width="600"
    >

和App.xaml中的资源

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    StartupUri="Window1.xaml">
  <Application.Resources>
    <ResourceDictionary>
      <ResourceDictionary.MergedDictionaries>
        <!-- MahApps.Metro resource dictionaries. Make sure that all file names are Case Sensitive! -->
        <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
        <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
        <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colors.xaml" />
        <!-- Accent and AppTheme setting -->
        <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" />
        <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
      </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
  </Application.Resources>

Answer 2

我只需要添加默认的资源字典

<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" /> <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />中的App.xaml
