'ismouseover'属性停留在'enteractions/exitactions'模式，如何更改按钮的焦点？请注意显示其工作原理的图像（GIF）

匿名

大家好。首先，我为我的语言语法感到抱歉，因为我的第一语言是波斯语（伊朗）。我创建了一个具有一系列效果的按钮，当 WPF 窗口打开时，这些效果可以正常工作。但是，当 PreviewMouseLeftButtonUp 事件完成并打开 Openfiledialog 窗口时，该按钮将保持焦点模式（IsMouseOver 属性保持 EnterActions 模式）。当我将按钮的焦点转移到另一个控件时，IsMouseOver 功能将保持 ExitActions 模式。

我希望按钮的工作方式与窗口第一次打开时完全相同，并且没有焦点控制。

Answer 1

在第 29 行和第 30 行之间插入以下代码：

var scope = FocusManager.GetFocusScope(sender as Button);   
FocusManager.SetFocusedElement(scope, null);   
Keyboard.ClearFocus();

并在问题的第一代码部分的第 224 行和第 225 行之间添加。<Setter Property="FocusManager.FocusedElement" Value="{Binding RelativeSource={RelativeSource Self}}"></Setter>
