如何 blocked/Inactivate Uwp app title bar due to show ContentDialog?

Question

由于显示 ContentDialog，我需要 blocked/Inactivate 带有标题栏的整个 Uwp 应用程序。我使用了 Microsoft XAML Controls Gallery App 的代码，而 Control-Gallery 应用程序正确阻止了整个应用程序，但我的测试应用程序没有阻止该应用程序。

这是在资源字典中添加 winui:XamlControlsResources ControlsResourcesVersion="Version2" 之后的另一个屏幕截图。这也可以通过覆盖 SystemControlPageBackgroundMediumAltMediumBrush.

来实现

<SolidColorBrush x:Key="SystemControlPageBackgroundMediumAltMediumBrush" Color="#000000" Opacity="0.18"/>

或

<Application
x:Class="App2.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:App2"
xmlns:winui="using:Microsoft.UI.Xaml.Controls">
<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <winui:XamlControlsResources ControlsResourcesVersion="Version2" />
        </ResourceDictionary.MergedDictionaries>            
    </ResourceDictionary>
</Application.Resources>

这里是使用的示例代码：

<Page
x:Class="App2.ContentDialogContent"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

<StackPanel HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
    <!--  Content body  -->
    <TextBlock Text="Lorem ipsum dolor sit amet, adipisicing elit." TextWrapping="Wrap" />
    <CheckBox Content="Upload your content to the cloud." />
</StackPanel>
</Page>

按钮点击：

    private async void button_Click(object sender, RoutedEventArgs e)
    {
        ContentDialog dialog = new ContentDialog();
        dialog.Title = "Save your work?";
        dialog.PrimaryButtonText = "Save";
        dialog.SecondaryButtonText = "Don't Save";
        dialog.CloseButtonText = "Cancel";
        dialog.DefaultButton = ContentDialogButton.Primary;
        dialog.Content = new ContentDialogContent();

        var result = await dialog.ShowAsync();

        if (result == ContentDialogResult.Primary)
        {
            //DialogResult.Text = "User saved their work";
        }
        else if (result == ContentDialogResult.Secondary)
        {
            //DialogResult.Text = "User did not save their work";
        }
        else
        {
            //DialogResult.Text = "User cancelled the dialog";
        }
      }

我已经使用了ExtendViewIntoTitleBar，但问题仍然存在于标题栏的系统按钮区域

Answer 1

正如 Rufo 爵士所说，您的预期视图已设置 ExtendViewIntoTitleBar 为真，可以将您的视图内容扩展到标题栏中。它可以使整个当前视图内容被 ContentDialog.

阻塞

使用 ExtendViewIntoTitleBar, please refer to Title bar customization.

var coreTitleBar = CoreApplication.GetCurrentView().TitleBar;
coreTitleBar.ExtendViewIntoTitleBar = true;

更新

您需要将标题栏按钮的背景颜色设置为透明。

ApplicationViewTitleBar titleBar = ApplicationView.GetForCurrentView().TitleBar;
titleBar.ButtonBackgroundColor = Colors.Transparent;
