我的TabItem
风格存在一些问题。这是风格:
<Style TargetType="{x:Type TabItem}">
<Setter Property="Width" Value="160"/>
<Setter Property="Background" Value="Transparent" />
<Setter Property="Height" Value="70"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="TabItem">
<Border Name="Border" Background="Transparent">
<ContentPresenter x:Name="ContentSite"
VerticalAlignment="Center"
HorizontalAlignment="Left"
ContentSource="Header"
Margin="10,2"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter TargetName="Border" Property="Background" Value="Red" />
</Trigger>
<Trigger Property="IsSelected" Value="False">
<Setter TargetName="Border" Property="Background" Value="Green" />
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="Border" Property="Background" Value="Blue" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
问题是IsMouseOver
事件也是通过在其任何子项上移动而触发的。
我已将SourceName="ContentSite"
添加到触发器:
<Trigger SourceName="ContentSite" Property="IsMouseOver" Value="True">
使用此代码,不再通过移动子元素触发IsMouseOver,但它引入了另一个问题。仅当光标位于tabitem的标题上时才会触发IsMouseOver事件。另一个用户对here描述了同样的问题。建议的答案是将Background =“Transparent”值添加到Border,但它对我没用。

如果我理解您的问题,您只需将SourceName
上的Trigger
更改为ContentSite
的边框。
请尝试以下风格:
<Style TargetType="{x:Type TabItem}">
<Setter Property="Width" Value="160"/>
<Setter Property="Background" Value="Transparent" />
<Setter Property="Height" Value="70"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="TabItem">
<Border Name="Border" Background="Transparent">
<ContentPresenter x:Name="ContentSite"
VerticalAlignment="Center"
HorizontalAlignment="Left"
ContentSource="Header"
Margin="10,2"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter TargetName="Border" Property="Background" Value="Red" />
</Trigger>
<Trigger Property="IsSelected" Value="False">
<Setter TargetName="Border" Property="Background" Value="Green" />
</Trigger>
<Trigger Property="IsMouseOver" Value="True" SourceName="Border">
<Setter TargetName="Border" Property="Background" Value="Blue" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
并且,如果您希望仅针对未选择的标签发生这种情况,您可以尝试以下MultiTrigger
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="IsMouseOver" SourceName="Border" Value="True" />
<Condition Property="IsSelected" Value="False" />
</MultiTrigger.Conditions>
<Setter TargetName="Border" Property="BorderBrush" Value="Blue" />
</MultiTrigger>
