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。
