windows-8 - 如何在 WinRT 中创建可滚动的画布？

Question

我试过这个，但我不能滚动画布。我试图处理其他控件的鼠标滚轮更改事件，但滚动不起作用。有人知道我做错了什么吗？

<Viewbox Stretch="Fill" StretchDirection="Both" Height="300" Width="300">
<ScrollViewer ScrollViewer.HorizontalScrollBarVisibility="Visible" ScrollViewer.HorizontalScrollMode="Enabled"
      ScrollViewer.VerticalScrollBarVisibility="Disabled" Margin="20,0,20,0" Height="300" Width="300">
    <Canvas Background="White" Height="300" Width="500">
        <TextBlock FontSize="20" Text="This Is Far Right" Canvas.Left="350" Foreground="Black" />
    </Canvas>
</ScrollViewer>
</Viewbox>

Answer 1

Try specify width and height of the canvas bigger than the outer element, eg.

<Canvas Background="White" Width="500" Height="500" />

Answer 2

ScrollViewer.VerticalScrollMode="Disabled"解决了我的问题。
