當默認按鈕或鼠標懸停在按鈕上時，如何將某種類型的高亮設置設置爲按鈕？

Question

這裏是我設計的一個按鈕，但是我意識到，當按鈕被鼠標懸停/選擇或者類似的東西時，使用應用程序的人沒有辦法注意到？ 我只是想要某種類型的通知，當選擇按鈕或任何？ 任何類型的解決方案對我來說都是可以接受的，所以如果按鈕是鼠標懸停的話，或者如果選擇了按鈕來注意用戶 那個按鈕！

這裏是我當前按鈕：

<Button x:Name="btnOk" 
        SnapsToDevicePixels="True" 
        UseLayoutRounding="True" 
        IsDefault="True" 
        Grid.Row="2" 
        Grid.Column="1" 
        FontSize="15" 
        Width="140" 
        BorderThickness="1" 
        HorizontalContentAlignment="Center" 
        VerticalContentAlignment="Center" 
        Foreground="#0091EA" 
        Background="White" 
        Content="Ok!" 
        BorderBrush="#0091EA" Margin="5,10,0,10" HorizontalAlignment="Left" Click="btnPotvrdi_Click"> 
      <Button.Style> 
       <Style TargetType="{x:Type Button}"> 
        <Style.Triggers> 
         <Trigger Property="IsMouseOver" Value="True"> 
          <Setter Property="Background" Value="BlueViolet"/> 
         </Trigger> 
        </Style.Triggers> 
       </Style> 
      </Button.Style> 
      <Button.Template> 
       <ControlTemplate TargetType="{x:Type Button}"> 
        <Border BorderThickness="{TemplateBinding BorderThickness}" 
           BorderBrush="{TemplateBinding BorderBrush}" 
           Background="{TemplateBinding Background}"> 
         <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" 
            VerticalAlignment="{TemplateBinding VerticalContentAlignment}" /> 
        </Border> 
       </ControlTemplate> 

      </Button.Template> 

     </Button>

指定在Style默認的背景（White），你的觸發器將如預期：

<Button x:Name="btnOk" 
        SnapsToDevicePixels="True" 
        UseLayoutRounding="True" 
        IsDefault="True" 
        Grid.Row="2" 
        Grid.Column="1" 
        FontSize="15" 
        Width="140" 
        BorderThickness="1" 
        HorizontalContentAlignment="Center" 
        VerticalContentAlignment="Center" 
        Foreground="#0091EA" 
        Content="Ok!" 
        BorderBrush="#0091EA" Margin="5,10,0,10" HorizontalAlignment="Left" Click="btnPotvrdi_Click"> 
    <Button.Style> 
     <Style TargetType="{x:Type Button}"> 
      <Setter Property="Background" Value="White" /> 
      <Style.Triggers> 
       <Trigger Property="IsFocused" Value="True"> 
        <Setter Property="Background" Value="Green"/> 
       </Trigger> 
       <Trigger Property="IsMouseOver" Value="True"> 
        <Setter Property="Background" Value="BlueViolet"/> 
       </Trigger> 
      </Style.Triggers> 
     </Style> 
    </Button.Style> 
    <Button.Template> 
     <ControlTemplate TargetType="{x:Type Button}"> 
      <Border BorderThickness="{TemplateBinding BorderThickness}" 
           BorderBrush="{TemplateBinding BorderBrush}" 
           Background="{TemplateBinding Background}"> 
       <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" 
            VerticalAlignment="{TemplateBinding VerticalContentAlignment}" /> 
      </Border> 
     </ControlTemplate> 
    </Button.Template> 
</Button>
