WPF 实现图标按钮
假设需要实现一个图标和文本结合的按钮 ，普通做法是 直接重写该按钮的模板；如果想作为通用的呢？
两种做法：
[*]附加属性
[*]自定义控件
推荐使用附加属性的形式
第一种：附加属性
创建Button的附加属性 ButtonExtensions
1 public static class ButtonExtensions
2 {
3 // Using a DependencyProperty as the backing store for IconWidth.This enables animation, styling, binding, etc...
4 public static readonly DependencyProperty IconWidthProperty =
5 DependencyProperty.RegisterAttached("IconWidth", typeof(int), typeof(ButtonExtensions), new PropertyMetadata(0));
6
7 public static int GetIconWidth(DependencyObject obj)
8 {
9 return (int)obj.GetValue(IconWidthProperty);
10 }
11
12 public static void SetIconWidth(DependencyObject obj, int value)
13 {
14 obj.SetValue(IconWidthProperty, value);
15 }
16
17 // Using a DependencyProperty as the backing store for IconHeight.This enables animation, styling, binding, etc...
18 public static readonly DependencyProperty IconHeightProperty =
19 DependencyProperty.RegisterAttached("IconHeight", typeof(int), typeof(ButtonExtensions), new PropertyMetadata(0));
20
21 public static int GetIconHeight(DependencyObject obj)
22 {
23 return (int)obj.GetValue(IconHeightProperty);
24 }
25
26 public static void SetIconHeight(DependencyObject obj, int value)
27 {
28 obj.SetValue(IconHeightProperty, value);
29 }
30
31 // Using a DependencyProperty as the backing store for IconGeometry.This enables animation, styling, binding, etc...
32 public static readonly DependencyProperty IconGeometryProperty =
33 DependencyProperty.RegisterAttached("IconGeometry", typeof(Geometry), typeof(ButtonExtensions), new PropertyMetadata((object)null));
34
35 public static Geometry GetIconGeometry(DependencyObject obj)
36 {
37 return (Geometry)obj.GetValue(IconGeometryProperty);
38 }
39
40 public static void SetIconGeometry(DependencyObject obj, Geometry value)
41 {
42 obj.SetValue(IconGeometryProperty, value);
43 }
44
45 }样式
1 <ResourceDictionary
2 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
3 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
4 xmlns:coreHelper="clr-namespace:NeonGenesis.Core.AttachedProperties;assembly=NeonGenesis.Core">
5
59 </ResourceDictionary>使用示例
1 <Button
2 Width="80"
3 Height="80"
4 coreHelper:ButtonExtensions.IconGeometry="{StaticResource RunningGeometry}"
5 coreHelper:ButtonExtensions.IconHeight="40"
6 coreHelper:ButtonExtensions.IconWidth="40"
7 Background="#1e90ff"
8 Content="运行"
9 Foreground="White"
10 Style="{StaticResource ButtonVerBase}" />RunningGeometry为

第二种：自定义控件
