布局WPF Viewport3d标度
布局WPF Viewport3d标度
提问于 2014-07-01 09:58:42
我有一个WPF窗口的简单布局，它的结构类似于一个StackPanel。一个菜单在顶部和一个大面积的viewport3d下面，我显示三维图形对象。如何将viewport3d元素设置为在菜单下面占用全部空闲空间？
我试过这样的基本设置..。
<StackPanel>
<Menu>
<MenuItem Header="File"></MenuItem>
</Menu>
<Viewport3D>
... some 3d content here
</Viewport3D>
</StackPanel>..。但是，这使得视口高度为零(宽度似乎已经适应了窗口的全宽度)。输入特定的高度是没有意义的，而Height="Auto"也没有使视口获得剩余的高度。也许StackPanel不是这里的正确选择？
我希望这个窗口可以调整大小。

您可以使用有2行的网格。第一行的高度设置为“自动”。第二行的高度设置为*。
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Menu Grid.Row="0">
<MenuItem Header="File"></MenuItem>
</Menu>
<Viewport3D Grid.Row="1">
... some 3d content here
</Viewport3D>
</Grid>下面是一个完整的示例(场景来自MS示例)：
<Window x:Class="WpfApplication1.MainWindow"

Title="MainWindow" Height="350" Width="525">

<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Menu Grid.Row="0">
<MenuItem Header="File"></MenuItem>
</Menu>
<Viewport3D Grid.Row="1">
