菜单控件 (WPF) 问题

Question

我想在我的应用程序中创建一个可缩放的菜单控件。我使用 this answer 创建了一个可缩放的 window，然后将 Menu 控件插入其中。我有一些问题，找不到解决方案。

如何设置菜单项的"center"垂直调整？现在它们停靠在顶部。有什么方法可以将第一项（在我的例子中是"File"）向右移动一点吗？

是否可以在 window 调整大小时避免剪切菜单面板？现在，即使我将内部网格的顶部边框向下移动一点，菜单面板也会被减半。

我的代码及其针对全屏和较小比例的结果如下：

<Window x:Class="DigitalSteelCastingWPF.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        HorizontalAlignment="Center" VerticalAlignment="Center"
        WindowStyle="ThreeDBorderWindow">

    <Grid Name="MainGrid" SizeChanged="MainGrid_SizeChanged">

        <Grid.LayoutTransform>
            <ScaleTransform x:Name="ApplicationScaleTransform"
                        CenterX="0"
                        CenterY="0"
                        ScaleX="{Binding ElementName=myMainWindow, Path=ScaleValue}"
                        ScaleY="{Binding ElementName=myMainWindow, Path=ScaleValue}" />
        </Grid.LayoutTransform>

        <Grid VerticalAlignment="Center" HorizontalAlignment="Center" Height="1025" Width="1928">

            <StackPanel VerticalAlignment="Top">
                <Menu Width="Auto" Height="50" VerticalAlignment="Center" FontSize="24">
                    <MenuItem Header="_File">
                        <MenuItem x:Name="New" Header="_New" Height="50" HorizontalAlignment="Left" Width="250"/>
                        <MenuItem x:Name="Open" Header="_Open" Height="50" HorizontalAlignment="Left" Width="250"/>

                    </MenuItem>
                    <MenuItem Header="_Tools">
                        <MenuItem x:Name="Options" Header="O_ptions" Height="50" HorizontalAlignment="Left" Width="250"/>
                    </MenuItem>
                </Menu>
            </StackPanel>

        </Grid>

    </Grid>

</Window>

您可以添加一个 Viewbox

 <Grid>
        ***<Viewbox Stretch="Fill">***
            <Grid VerticalAlignment="Center" HorizontalAlignment="Center"  Height="1025" Width="1928">

                <StackPanel VerticalAlignment="Top">
                    <Menu Width="Auto" Height="50" VerticalAlignment="Center" FontSize="24">
                        <MenuItem Header="_File">
                            <MenuItem x:Name="New" Header="_New" Height="50" HorizontalAlignment="Left" Width="250"/>
                            <MenuItem x:Name="Open" Header="_Open" Height="50" HorizontalAlignment="Left" Width="250"/>
                            <MenuItem x:Name="Exit" Header="_Exit" Height="50" HorizontalAlignment="Left" Width="250"/>
                        </MenuItem>
                        <MenuItem Header="_Tools">
                            <MenuItem x:Name="Options" Header="O_ptions" Height="50" HorizontalAlignment="Left" Width="250"/>
                        </MenuItem>
                    </Menu>
                </StackPanel>

            </Grid>
        ***</Viewbox>***
        <Grid.LayoutTransform>
            <ScaleTransform x:Name="ApplicationScaleTransform"
                        CenterX="0"
                        CenterY="0"
                        ScaleX="{Binding ElementName=myMainWindow, Path=ScaleValue}"
                        ScaleY="{Binding ElementName=myMainWindow, Path=ScaleValue}" />
        </Grid.LayoutTransform>
