更改Windows经典主题中的禁用列表框的背景颜色 [英] Change background color of disabled listbox in windows classic theme

问题描述

我正在开发必须使用Windows Classic主题运行的WPF应用程序。该应用程序将创建一个包含ListBox的对话框。显示对话框时，必须先禁用1秒钟，然后再接受任何输入。我使用样式触发器来完成此操作，并且它可以正常工作。但是，列表框在禁用时会显示白色背景，我似乎无法消除它。使用Aero主题时，以下样式资源可解决此问题：

I am developing a WPF application that must run using Windows Classic theme. The application creates a dialog box containing a ListBox. When the dialog box is shown, it must be disabled for 1s before accepting any input. I am accomplishing this with a style trigger, and it works. However, the ListBox shows a white background when it's disabled, which I can't seem to get rid of. When using the aero theme, the following style resource fixes the issue:

<SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent"/>

但是使用Windows经典主题时，白色背景会重新出现。我该如何纠正经典主题的情况？？

But when using Windows Classic theme, the white background reappears. How can i remedy the situation for Classic theme???

推荐答案

经过进一步研究，我发现Windows经典主题使用WindowBrushKey而不是ControlBrushKey。因此，这可以解决Aero和Classic主题的问题：

After further research, I discovered that the Windows Classic theme uses WindowBrushKey instead of ControlBrushKey. Therefore, this fixes the issue for both Aero and Classic themes:

<Style TargetType="{x:Type ListBox}">
    <Style.Resources>
        <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent"/>
        <SolidColorBrush x:Key="{x:Static SystemColors.WindowBrushKey}" Color="Transparent"/>
    </Style.Resources>
