最大化窗口时如何增加边框厚度的示例。否则,由于 WindowChrome 的怪异,边框会消失。

<Window ResizeMode="CanResizeWithGrip"
WindowStyle="SingleBorderWindow">
<!-- Remove window header and border. Use with ResizeMode="CanResizeWithGrip" and WindowStyle="SingleBorderWindow". -->
<WindowChrome.WindowChrome>

CornerRadius ="0"
ResizeBorderThickness="4"
GlassFrameThickness="0">
</WindowChrome>
</WindowChrome.WindowChrome>
<Border BorderThickness="1">

<Style TargetType="{x:Type Border}">
<Style.Triggers>
<!-- Add to avoid border disappearing when window is maximised -->
<DataTrigger Binding="{Binding WindowState, RelativeSource={RelativeSource AncestorType=Window}}"
Value="Maximized">
<Setter Property="Margin" Value="10"/>
