我想在ScatterViewItems之间画线,但它不适用于我已经在这里找到的东西。有一条线,但没有连接到椭圆的中心。有人看到我的错误吗?以下是我有:用线连接ScatterViewItems
<Grid>
<s:ScatterView>
<s:ScatterViewItem Height="250" Width="500" Background="Transparent" Orientation="0" HorizontalAlignment="Right" Margin="0,70,-764,-70" d:LayoutOverrides="HorizontalAlignment, Width">
<s:ScatterView Height="250" Width="500" Background="BlueViolet">
<s:ScatterViewItem Background="Transparent" Center="100,145" Orientation="0">
<Label Content="Knoten A" Background="WhiteSmoke" Foreground="Black"/>
</s:ScatterViewItem>
<s:ScatterViewItem x:Name="StartItem" CanMove="False" CanRotate="False" Margin="0" Center="10,125" Background="Transparent">
<Ellipse Width="10" Height="10" Fill="Transparent" Stroke="Black" Margin="0,0,0,0"/>
</s:ScatterViewItem>
<s:ScatterViewItem x:Name="EndItem" CanMove="False" CanRotate="False" Margin="0" Center="490,125" Background="Transparent">
<Ellipse Width="10" Height="10" Fill="Transparent" Stroke="Black" Margin="0,0,0,0"/>
</s:ScatterViewItem>
<s:ScatterViewItem Background="Transparent">
<Canvas Name="LineHost"/>
</s:ScatterViewItem>
</s:ScatterView>
</s:ScatterViewItem>
</s:ScatterView>
</Grid>
和C#
Line line = new Line { Stroke = Brushes.Black, StrokeThickness = 2.0 };
BindLineToScatterViewItems(line, StartItem, EndItem);
LineHost.Children.Add(line);
private void BindLineToScatterViewItems(Line line, ScatterViewItem StartItem, ScatterViewItem EndItem)
{
BindingOperations.SetBinding(line, Line.X1Property,
new Binding {Source = StartItem, Path = new PropertyPath("ActualCenter.X")});
BindingOperations.SetBinding(line, Line.Y1Property,
new Binding { Source = StartItem, Path = new PropertyPath("ActualCenter.Y") });
BindingOperations.SetBinding(line, Line.X2Property,
new Binding { Source = EndItem, Path = new PropertyPath("ActualCenter.X") });
BindingOperations.SetBinding(line, Line.Y2Property,
new Binding { Source = EndItem, Path = new PropertyPath("ActualCenter.Y") });
}
谢谢,我刚刚也看到了它;-)现在这条线在那里,但没有连接到椭圆。任何想法为什么? – Judith
你可以发布它的截图吗? ;) –
