我想创建一个可以容纳多个控件的Window。但是,我希望用户能够平移并放大和缩小以查看这些控件的更大版本。
我甚至不知道从哪里开始寻找。
我将开始使用ScaleTransform来响应鼠标上滚动按钮的使用,但我不确定这是不是最好的主意。
只需要朝着正确的方向努力。
谢谢!

这可能是Viewbox
的合适人选。
见这里:http://msdn.microsoft.com/en-us/library/system.windows.controls.viewbox(v=vs.110).aspx
基本上,您可以将窗口的全部内容包装成Viewbox
,如下所示:
<Window>
<Viewbox>
<!-- content here -->
</Viewbox>
</Window>
然后绑定到Viewbox
控件的宽度和高度以模拟缩放。对于快速测试,您可以通过代码隐藏来监听滚轮事件,命名Viewbox控件,并在更改其中的值时直接访问Viewbox。
编辑:这是我刚刚找到的让您入门的方案。他们正在使用图像,但它与我上面描述的完全相同。

Edit2:使用鼠标滚动的快速工作示例
的Xaml:
<Window x:Class="WpfApplication2.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow"
MouseWheel="MainWindow_OnMouseWheel">
<Grid>
<Viewbox x:Name="ZoomViewbox" Stretch="Fill">
<StackPanel>
<Label Content="Label" HorizontalAlignment="Left" VerticalAlignment="Top"/>
<Button Content="Button" HorizontalAlignment="Left" VerticalAlignment="Top" />
</StackPanel>
</Viewbox>
</Grid>
</Window>
C#:
using System.Windows;
using System.Windows.Input;
namespace WpfApplication2
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
ZoomViewbox.Width = 100;
ZoomViewbox.Height = 100;
}
private void MainWindow_OnMouseWheel(object sender, MouseWheelEventArgs e)
{
UpdateViewBox((e.Delta > 0) ? 5 : -5);
}
private void UpdateViewBox(int newValue)
{
if ((ZoomViewbox.Width >= 0) && ZoomViewbox.Height >= 0)
{
ZoomViewbox.Width += newValue;
ZoomViewbox.Height += newValue;
}
}
}
}

您可以从ScrollViewer和ScaleTransform中获取功能。这是一个例子:
<Window x:Class="CSharpWpf.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<!-- This ScrollViewer enabled the "panning" -->
<ScrollViewer HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto">
<!-- This StackPanel is the container for the zoomable/pannable content. Any container control (StackPanel, DockPanel, Grid, etc) may be used here. -->
<StackPanel HorizontalAlignment="Left" VerticalAlignment="Top">
<StackPanel.LayoutTransform>
<!-- This ScaleTransform implements the zooming and is bound the Value of the ZoomSlider -->
<ScaleTransform ScaleX="{Binding ElementName=ZoomSlider, Path=Value}" ScaleY="{Binding ElementName=ZoomSlider, Path=Value}" />
</StackPanel.LayoutTransform>
<Button>Foo</Button>
<Button>Bar</Button>
</StackPanel>
</ScrollViewer>
<!-- This Slider controls the zoom level -->
<Slider x:Name="ZoomSlider" Orientation="Horizontal" Grid.Row="1" Minimum="0.0" Maximum="8.0" LargeChange="0.25" SmallChange="0.01" Value="1.0" />
</Grid>
</Window>

简单的解决方案:
private void Window_PreviewMouseWheel(object sender, MouseWheelEventArgs e)
{
if (Keyboard.Modifiers != ModifierKeys.Control)
return;
if (e.Delta < 0 && _scale > 0.7)
{
_scale -= 0.1;
MainGrid.LayoutTransform = new ScaleTransform(_scale, _scale);
}
else if (e.Delta > 0 && _scale < 1.5)
{
_scale += 0.1;
MainGrid.LayoutTransform = new ScaleTransform(_scale, _scale);
}
}
