我需要使用 WPF 的 ListBox 控件在容器中绘制线条。使用 Listbox 控件的原因是我有一组对象，这些对象基本上是自定义 Line 对象，暴露 x1,y1 和 x2,y2 点。因此，一旦绘制了将添加到集合中的线，它就可以同时显示。
我用来在列表框中画线的代码是：
<ListBox Grid.Row="0" Grid.Column="0" VerticalContentAlignment="Stretch" HorizontalContentAlignment="Stretch" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Grid.ColumnSpan="4" Grid.RowSpan="4" Name="listBoxLines" Visibility="{Binding ElementName=RadioCaliperOn, Path=IsChecked, Converter={StaticResource booleanToVisibilityConverter}}" Style="{x:Null}" Background="Transparent" BorderThickness="0" ScrollViewer.HorizontalScrollBarVisibility="Disabled" ScrollViewer.VerticalScrollBarVisibility="Disabled" ItemsSource="{Binding Path=Calipers}" >
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<Canvas HorizontalAlignment="Stretch" VerticalAlignment="Stretch"></Canvas>
<!--<Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch"></Grid>-->
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.Resources>
<Style TargetType="ListBoxItem">
<Style.Resources>
<!-- Background of selected item when focussed -->
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" />
<!-- Background of selected item when not focussed -->
<SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent" />
</Style.Resources>
<Style.Setters>
<!--<Setter Property="Background" Value="{StaticResource Brush_CZBscanImagePinkBorder}"/>-->
<Setter Property="Background" Value="Transparent"/>
<Setter Property="Foreground" Value="Transparent"/>
<Setter Property="BorderThickness" Value="0"/>
<Setter Property="Margin" Value="0"/>
<Setter Property="Padding" Value="0" />
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
<Setter Property="VerticalContentAlignment" Value="Stretch"/>
<Setter Property="MinHeight" Value="1"/>
<Setter Property="MinWidth" Value="1"/>
<Setter Property="Height" Value="Auto"/>
<Setter Property="Width" Value="Auto"/>
</Style.Setters>
<Style.Triggers>
<Trigger Property="IsSelected" Value="true">
<Setter Property="Background" Value="{StaticResource BrushTransparent}"/>
<Setter Property="Foreground" Value="{StaticResource BrushTransparent}"/>
</Trigger>
</Style.Triggers>
</Style>
<Style TargetType="ListBox">
<Style.Setters>
<Setter Property="ListBox.BorderThickness" Value="0"></Setter>
</Style.Setters>
</Style>
<Style TargetType="ScrollViewer">
<Style.Setters>
<Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Disabled"></Setter>
<Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Disabled"></Setter>
</Style.Setters>
</Style>
</ListBox.Resources>
<ListBox.ItemTemplate>
<DataTemplate>
<Line Cursor="Hand" X1="{Binding Converter={StaticResource caliperToLineConverter}, ConverterParameter=X1}" Y1="{Binding Converter={StaticResource caliperToLineConverter}, ConverterParameter=Y1}" X2="{Binding Converter={StaticResource caliperToLineConverter}, ConverterParameter=X2}" Y2="{Binding Converter={StaticResource caliperToLineConverter}, ConverterParameter=Y2}" Stroke="{Binding Converter={StaticResource selectedCalliperColorConverter},RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type ListBoxItem}}, Path=IsSelected}" StrokeThickness="2" Height="Auto" Margin="0,0,0,0" Stretch="Fill"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
我面临的问题是，如果集合中有任何现有的行，那么当我只需鼠标单击我的容器来绘制一条线时，列表框的现有项目就会被选中，而我又不能画任何一条线。请让我知道我可以轻松绘制线条的确切方式或方法，每条线都是列表框的一个项目。谢谢。
