WPF控件自绘——基础，Control类的定义

用于记录自己的学习WPF控件，大神请飘过。。。

【WPF控件类继承关系图】

所有可以自定义模版的控件都是从Control继承，所以我们来看看Contorl类里面到底有些什么。为以后的控件自定义模版做好准备。废话少说先来看看WPF中Control类的定义

 1 namespace System.Windows.Controls
 2 {
 3   public class Control : FrameworkElement
 4   {
 5     public static readonly DependencyProperty BorderBrushProperty;
 6     public static readonly DependencyProperty BorderThicknessProperty;
 7     public static readonly DependencyProperty BackgroundProperty;
 8     public static readonly DependencyProperty ForegroundProperty;
 9     public static readonly DependencyProperty FontFamilyProperty;
10     public static readonly DependencyProperty FontSizeProperty;
11     public static readonly DependencyProperty FontStretchProperty;
12     public static readonly DependencyProperty FontStyleProperty;
13     public static readonly DependencyProperty FontWeightProperty;
14     public static readonly DependencyProperty HorizontalContentAlignmentProperty;
15     public static readonly DependencyProperty VerticalContentAlignmentProperty;
16     public static readonly DependencyProperty TabIndexProperty;
17     public static readonly DependencyProperty IsTabStopProperty;
18     public static readonly DependencyProperty PaddingProperty;
19     public static readonly DependencyProperty TemplateProperty;//以上为依赖属性的定义，主要看下面的这些属性和方法
20     public static readonly RoutedEvent PreviewMouseDoubleClickEvent;
21     public static readonly RoutedEvent MouseDoubleClickEvent;//以上两个为路由事件
22     public Control();//模版发生改变时调用此事件
23     protected virtual void OnTemplateChanged(ControlTemplate oldTemplate, ControlTemplate newTemplate);
24     public override string ToString();
25     protected virtual void OnPreviewMouseDoubleClick(MouseButtonEventArgs e);
26     protected virtual void OnMouseDoubleClick(MouseButtonEventArgs e);
27     protected override Size MeasureOverride(Size constraint);
28     protected override Size ArrangeOverride(Size arrangeBounds);
29     [Bindable(true)]
30     [Category("Appearance")]
31     public Brush BorderBrush { get; set; } //边框颜色画刷
32     [Bindable(true)]
33     [Category("Appearance")]
34     public Thickness BorderThickness { get; set; } //边框大小
35     [Bindable(true)]
36     [Category("Appearance")]
37     public Brush Background { get; set; }   //背景颜色
38     [Category("Appearance")]
39     [Bindable(true)]
40     public Brush Foreground { get; set; }    //前景颜色
41     [Bindable(true)]
42     [Category("Appearance")]
43     [Localizability(LocalizationCategory.Font)]
44     public FontFamily FontFamily { get; set; }  //字体
45     [Category("Appearance")]
46     [Localizability(LocalizationCategory.None)]
47     [TypeConverter(typeof (FontSizeConverter))]
48     [Bindable(true)]
49     public double FontSize { get; set; }  //字体大小
50     [Bindable(true)]
51     [Category("Appearance")]
52     public FontStretch FontStretch { get; set; } //字体拉伸描述字体形状从其普通纵横比拉伸的程度，普通纵横比是为字体中的标志符号指定的宽度与高度的原始比例。
53     [Bindable(true)]
54     [Category("Appearance")]
55     public FontStyle FontStyle { get; set; }  //字体风格 ，设置字体的倾斜特性
56     [Category("Appearance")]
57     [Bindable(true)]
58     public FontWeight FontWeight { get; set; } //字体加粗效果
59     [Category("Layout")]
60     [Bindable(true)]
61     public HorizontalAlignment HorizontalContentAlignment { get; set; }  //这个属性用来设置该控件相对父控件的横向摆放位置，而不是控件内的内容的摆放位置
62     [Bindable(true)]
63     [Category("Layout")]
64     public VerticalAlignment VerticalContentAlignment { get; set; }
65     [Category("Behavior")]
66     [Bindable(true)]
67     public int TabIndex { get; set; }  //支持Tab键切换焦点，用来设置tab键切换的顺序
68     [Category("Behavior")]
69     [Bindable(true)]
70     public bool IsTabStop { get; set; } //用来控制是否接受tab键的焦点切换
71     [Category("Layout")]
72     [Bindable(true)]
73     public Thickness Padding { get; set; } //控件内的内容与控件的边界的间距//模版属性，后面在自绘控件时再详细介绍。
74     public ControlTemplate Template { [TargetedPatchingOptOut("Performance critical to inline this type of method across NGen image boundaries")] get; set; }
75     protected internal virtual bool HandlesScrolling { get; }  //获取一个值，该值指示组合框是否支持滚动。
76     public event MouseButtonEventHandler PreviewMouseDoubleClick;
77     public event MouseButtonEventHandler MouseDoubleClick;
78   }
79 }

以上属性都比较简单，就只简单介绍下，在我们自绘控件时知道有这些属性就好了。
