WPF如何在列表框失去焦点时更改列表框所选项目的文本颜色

问题描述

我一直在寻找如何更改失去焦点的列表框中所选项目的文本颜色.

I've been searching for how to change the text color of a selected item in a list box that has lost focus.

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

这三个标记可完成大部分工作，但是我的列表框具有黑色背景，并且当控件失去焦点时，字体将变为黑色.

These three tags take care of most of the work, but my list box has a black background and when the control loses focus, the font turns to black.

我从另一篇帖子 SystemColor中找到了此列表.键(该键提供了该列表中的很多可能选项)，所有看起来遥不可及的操作均无效.有人知道我需要更改的密钥吗?

I found this list from another post SystemColor. Keys that gives a ton of possible options from this list and anything that seems remotely intuitive has not worked. Does anybody know the key that I need to change?

推荐答案

我将其放在资源字典中，用于包含列表框的元素:

I put this in a resource dictionary for an element containing the listbox:

               <Style TargetType="ListBoxItem">
                <Style.Resources>
                    <!--SelectedItem with focus-->
                    <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Blue"/>
                    <SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="White"/>
                    <!--SelectedItem without focus-->
                    <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Blue"/>
                    <SolidColorBrush x:Key="{x:Static SystemColors.ControlTextBrushKey}" Color="White"/>
                </Style.Resources>
            </Style>

还请注意，在.Net 4.5中，您必须通过设置来要求旧的"行为

Notice also that in .Net 4.5 you have to ask for "old" behavior by setting

      FrameworkCompatibilityPreferences.
            AreInactiveSelectionHighlightBrushKeysSupported = false;

在程序中早于创建任何窗口.

early in your program before any windows are created.
