我想创建一个继承自Border的控件,并且只允许我特定一个StrokeDashArray来破坏边界线.
我不想使用’谷歌’建议的黑客,即矩形等,因为我想要边境控制给予的灵活性.
但是,我没有创建自定义控件的经验,也不知道从哪里开始？
你能指出我正确的方向吗？
谢谢！
解决方法
仍然不是最佳的,但如何使用Matt Hamilton作为VisualBrush的链接解决方案
使用VisualBrush与虚线矩形和SolidColorBrush进行比较
<Border BorderThickness="3,2,1,0" CornerRadius="10">
<Border.BorderBrush>
<VisualBrush>
<VisualBrush.Visual>
<Rectangle StrokeDashArray="1.0 1.0"
Stroke="Red"
StrokeThickness="{Binding RelativeSource={RelativeSource AncestorType={x:Type Border}},Path=BorderThickness,Converter={StaticResource ThicknessMaxConverter}}"
RadiusX="{Binding RelativeSource={RelativeSource AncestorType={x:Type Border}},Path=CornerRadius.TopRight}"
RadiusY="{Binding RelativeSource={RelativeSource AncestorType={x:Type Border}},Path=CornerRadius.BottomLeft}"
Width="{Binding RelativeSource={RelativeSource AncestorType={x:Type Border}},Path=ActualWidth}"
Height="{Binding RelativeSource={RelativeSource AncestorType={x:Type Border}},Path=ActualHeight}"/>
</VisualBrush.Visual>
</VisualBrush>
</Border.BorderBrush>
</Border>
ThicknessMaxConverter
public class ThicknessMaxConverter : IValueConverter
{
public object Convert(object value,Type targetType,object parameter,System.Globalization.CultureInfo culture)
{
Thickness thickness = (Thickness)value;
double horizontalMax = Math.Max(thickness.Left,thickness.Right);
double verticalMax = Math.Max(thickness.Top,thickness.Bottom);
return Math.Max(horizontalMax,verticalMax);
}
public object ConvertBack(object value,System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
}
