我正在尝试在 WPF 中创建类似于下图的内容。这个控件被设计为我的应用程序中所有内容的基本视图，并将位于带有背景（可能是某种渐变）的 Window 控件中。
要求如下：
我已经为此奋斗了好几个小时，但是作为 WPF 的新手，我开始发现自己在兜圈子。我认为 WPF 的灵活性有很大的好处，但对于刚入门的人来说，这几乎是太令人生畏了。
任何帮助将不胜感激！谢谢！

我不知道如何“填充”剪辑，所以我用代码制作了剪辑。如果您需要更多帮助来添加更多属性以控制颜色等，请告诉我。 如下：
代码：
public class Tabby : HeaderedContentControl
{
static Tabby()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(Tabby), new FrameworkPropertyMetadata(typeof(Tabby)));
}
public double DogEar
{
get { return (double)GetValue(DogEarProperty); }
set { SetValue(DogEarProperty, value); }
}
public static readonly DependencyProperty DogEarProperty =
DependencyProperty.Register("DogEar",
typeof(double),
typeof(Tabby),
new UIPropertyMetadata(8.0, DogEarPropertyChanged));
private static void DogEarPropertyChanged(
DependencyObject obj,
DependencyPropertyChangedEventArgs e)
{
((Tabby)obj).InvalidateVisual();
}
public Tabby()
{
this.SizeChanged += new SizeChangedEventHandler(Tabby_SizeChanged);
}
void Tabby_SizeChanged(object sender, SizeChangedEventArgs e)
{
var clip = new PathGeometry();
clip.Figures = new PathFigureCollection();
clip.Figures.Add(
new PathFigure(
new Point(0, 0),
new[] {
new LineSegment(new Point(this.ActualWidth - DogEar, 0), true),
new LineSegment(new Point(this.ActualWidth, DogEar), true),
new LineSegment(new Point(this.ActualWidth, this.ActualHeight), true),
new LineSegment(new Point(0, this.ActualHeight), true) },
true)
);
this.Clip = clip;
}
}
Generic.xaml
<Style TargetType="{x:Type local:Tabby}">
<Setter Property="Padding"
Value="5" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:Tabby}">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="auto" />
<RowDefinition Height="auto" />
</Grid.RowDefinitions>
<Border CornerRadius="3,0,0,0"
BorderBrush="Black"
BorderThickness="1"
Background="Black">
<ContentPresenter Content="{TemplateBinding Header}"
Margin="{TemplateBinding Padding}" />
</Border>
<Border CornerRadius="0,0,3,3"
BorderBrush="Black"
BorderThickness="1"
Background="White"
Grid.Row="1">
<ContentPresenter Content="{TemplateBinding Content}"
Margin="{TemplateBinding Padding}" />
</Border>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
使用它：
<my:Tabby DogEar="12"
x:Name="tabby1">
<my:Tabby.Header>
<TextBlock Foreground="White">Header</TextBlock>
</my:Tabby.Header>
<my:Tabby.Content>
<TextBlock Text="Content can be anything" />
</my:Tabby.Content>
</my:Tabby>

试试这个开始：
<Grid Width="100" Height="100">
<Border Background="Green" CornerRadius="8,0,8,8">
<Border.Clip>
<PathGeometry>
<PathGeometry.Figures>
<PathFigure StartPoint="0,0">
<PathFigure.Segments>
<LineSegment Point="90,0"/>
<LineSegment Point="100,10"/>
<LineSegment Point="100,100"/>
<LineSegment Point="0,100"/>
</PathFigure.Segments>
</PathFigure>
</PathGeometry.Figures>
</PathGeometry>
</Border.Clip>
</Border>
</Grid>

这是我使用自定义控件编写的一些代码。
控制代码：
using System;
using System.Windows;
using System.Windows.Controls;
namespace Test
{
public class ContentCard : HeaderedContentControl
{
static ContentCard()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(ContentCard), new FrameworkPropertyMetadata(typeof(ContentCard)));
}
}
}
控制 xaml（在 Themes/Generic.xaml 文件夹中）
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:test="clr-namespace:Test">
<Style TargetType="{x:Type test:ContentCard}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type test:ContentCard}">
<Grid Background="Transparent">
<Grid.RowDefinitions>
<RowDefinition Height="30" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="20" />
</Grid.ColumnDefinitions>
<Border Grid.Row="0" Grid.Column="0" Background="{TemplateBinding Background}" CornerRadius="10,0,0,0" Height="30">
<ContentControl Content="{TemplateBinding Header}" VerticalAlignment="Center" Margin="10,0,0,0" />
</Border>
<Path Grid.Row="0" Grid.Column="1" Fill="{TemplateBinding Background}" Data="M0,0 L20,15 L20,30 L0,30 L0,0Z"/>
<Border Grid.Row="1" Grid.ColumnSpan="2" BorderBrush="{TemplateBinding Background}" BorderThickness="1,0,1,1" CornerRadius="0,0,10,10" Padding="5" Background="White">
<ContentControl Content="{TemplateBinding Content}" />
</Border>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ResourceDictionary>
这是你使用它的方式：
<test:ContentCard Grid.RowSpan="4" Grid.ColumnSpan="2" Margin="200" Background="Black">
<test:ContentCard.Header>
<TextBlock Text="Title" Foreground="White" />
</test:ContentCard.Header>
<test:ContentCard.Content>
<TextBlock Text="This is some content" Foreground="Black" />
</test:ContentCard.Content>
</test:ContentCard>

感谢您的帖子，这真是太棒了！ 我已经修改以制作我自己的切角边框类和下面的相同用法
public class CornerCutBorder : Border
{
public CornerRadius CornerCutSize
{
get { return (CornerRadius)GetValue(CornerCutSizeProperty); }
set { SetValue(CornerCutSizeProperty, value); }
}
public static readonly DependencyProperty CornerCutSizeProperty = DependencyProperty.Register("CornerCutSize", typeof(CornerRadius),typeof(CornerCutBorder),new UIPropertyMetadata(new CornerRadius(), DogEarPropertyChanged));
private static void DogEarPropertyChanged(DependencyObject obj,DependencyPropertyChangedEventArgs e)
{
((CornerCutBorder)obj).Resized();
}
public CornerCutBorder()
{
this.SizeChanged += new SizeChangedEventHandler(Border_SizeChanged);
}
void Border_SizeChanged(object sender, SizeChangedEventArgs e)
{
Resized();
}
void Resized()
{
var clip = new PathGeometry();
clip.Figures = new PathFigureCollection();
RectangleGeometry rectangleGeometry = new RectangleGeometry(new Rect()
{
Width = this.ActualWidth,
Height = this.ActualHeight
});
clip.AddGeometry(rectangleGeometry);
if (CornerCutSize.TopLeft > 0)
{
clip.Figures.Add(
new PathFigure(
new Point(0, 0),
new[] {
new LineSegment(new Point(CornerCutSize.TopLeft, 0), true),
new LineSegment(new Point(0, CornerCutSize.TopLeft), true) },
true)
);
}
if (CornerCutSize.TopRight > 0)
{
clip.Figures.Add(
new PathFigure(
new Point(this.ActualWidth - CornerCutSize.TopRight, 0),
new[] {
new LineSegment(new Point(this.ActualWidth, 0), true),
new LineSegment(new Point(this.ActualWidth, CornerCutSize.TopRight), true) },
true)
);
}
if (CornerCutSize.BottomLeft > 0)
{
clip.Figures.Add(
new PathFigure(
new Point(0, this.ActualHeight - CornerCutSize.BottomLeft),
new[] {
new LineSegment(new Point(0, this.ActualHeight), true),
new LineSegment(new Point(CornerCutSize.BottomLeft, this.ActualHeight), true) },
true)
);
}
if (CornerCutSize.BottomRight > 0)
{
clip.Figures.Add(
new PathFigure(
new Point(this.ActualWidth - CornerCutSize.BottomRight, this.ActualHeight),
new[] {
new LineSegment(new Point(this.ActualWidth, this.ActualHeight), true),
new LineSegment(new Point(this.ActualWidth, this.ActualHeight-CornerCutSize.BottomRight), true) },
true)
);
}
this.Clip = clip;
}
}
<local:CornerCutBorder CornerCutSize="30,100,100,50" Width="600" Height="400" BorderThickness="2" Background="Red" ></local:CornerCutBorder>
