我在ItemsControl中使用Canvas,可以绘制矩形,圆形等形状。我想调整大小并移动绘制的形状。我尝试过使用装饰器,但没有找到在ItemsControl中使用装饰器的方法,这可能吗?
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<zc:ZoomableCanvas Loaded="Canvas_Loaded"
RealizationLimit="1000"
RealizationRate="10"
RealizationPriority="Background"
ApplyTransform="False"
Scale="{Binding ZoomableCanvas.Scale}"
Offset="{Binding ZoomableCanvas.Offset}" ClipToBounds="True"
Width="{Binding ZoomableCanvas.ActualWidth}"
Height="{Binding ZoomableCanvas.ActualHeight}"
>
</zc:ZoomableCanvas>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>

答案可能有点迟了,但我写这篇文章以供将来参考。
您使用的Canvas
只能在AdornerDecorator
内显示装饰者。试试这个:
<AdornerDecorator>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<zc:ZoomableCanvas Loaded="Canvas_Loaded"
RealizationLimit="1000"
RealizationRate="10"
RealizationPriority="Background"
ApplyTransform="False"
Scale="{Binding ZoomableCanvas.Scale}"
Offset="{Binding ZoomableCanvas.Offset}"
ClipToBounds="True"
Width="{Binding ZoomableCanvas.ActualWidth}"
Height="{Binding ZoomableCanvas.ActualHeight}"
>
</zc:ZoomableCanvas>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</AdornerDecorator>
我希望这有帮助!
