在 WPF 中触发继承? [英] Trigger inheritance in WPF?

问题描述

我有 2 个用于 WPF TabItem 控件的触发器，除了这一行之外，两者都是相同的:

I have 2 triggers for a WPF TabItem control, both are identical except for this line:

 <Setter Property="Opacity" Value="0.8" />

有什么办法可以让 IsMouseOver 的触发器从 IsSelected 继承并简单地添加额外的 setter?如果可能的话，请您提供一个示例

Is there any way I can make the trigger for IsMouseOver inherit from IsSelected and simply add the additional setter?Could you please provide an example if something like this is possible

完整的 XAML:

<ControlTemplate.Triggers>
    <Trigger Property="IsSelected" Value="True">
        <Setter Property="Panel.ZIndex" Value="100" />
        <Setter TargetName="Border" Property="BorderThickness" Value="1" />
    </Trigger>
    <Trigger Property="IsMouseOver" Value="True">
        <Setter Property="Panel.ZIndex" Value="100" />
        <Setter TargetName="Border" Property="BorderThickness" Value="1" />
        <Setter Property="Opacity" Value="0.8" />
    </Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>

推荐答案

触发器不会相互继承.您尝试做的事情是不可能的.

Triggers don't inherit from each other. What you're trying to do isn't possible.

样式可以相互继承，但触发器不能.

You can have styles inherit from each other, but not triggers.
