学会怎样给用户提供事件接口，本例子中通过监视Dock的变化事件，让用户可以在dock变化时候，自定义下一步操作
效果图：
| 版本号 | 状态 | 版本更新说明 |
| 1.0 | √ | 完成基本图文显示混带，DOCK变化自动调整，难点IsCustomed自定义用户控件外观，用户自己定义外观 |
| 1.2 |
√ |
增加IconDockPlacementValueChanged事件:用于IconDockPlacement值变化后的客户定义操作 增加IsCustomed=false纯图标显示、文本、提示、Dock值变化的混搭、暂未添加IsCustomed=true的自动调整 完成 |
| 1.3 | 待 | 增加 AyImageButton容器容器控件，增加 IsPressed,IsMouseEnter,IsMouseOut,IsEnabled状态的自定义效果 |

AyImageButton 1.2开始继续制作
1. 给用户增加路由事件，让用户可以在Dock值变化的时候触发该事件，并简单定义个Raise
#region 提供用户截获Dock变化时候事件 2015-02-04 09:35:29 private static readonly RoutedEvent IconDockPlacementValueChangedEvent = EventManager.RegisterRoutedEvent("IconDockPlacementValueChanged", RoutingStrategy.Bubble, typeof(RoutedPropertyChangedEventHandler<Dock>), typeof(AyImageButton)); public event RoutedPropertyChangedEventHandler<Dock> IconDockPlacementValueChanged { add { AddHandler(IconDockPlacementValueChangedEvent, value); } remove { RemoveHandler(IconDockPlacementValueChangedEvent, value); } } private void IconDChanged(Dock oldDock, Dock newDock) { RoutedPropertyChangedEventArgs<Dock> args = new RoutedPropertyChangedEventArgs<Dock>(oldDock, newDock); args.RoutedEvent = AyImageButton.IconDockPlacementValueChangedEvent; RaiseEvent(args); } #endregion
那么光定义是没用的，我们要在哪里调用IconDChanged方法呢？当然在IconDockPlacementProperty的回调函数IconDockPlacementChanged里面了，因为可以拿到旧值和新值
private static void IconDockPlacementChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) { AyImageButton aybtn = (AyImageButton)d; Dock newDock = (Dock)e.NewValue; //e.Property 是被修改的属性,这里就是IconDockPlacement //调整文字摆放方式 IconDockChanged(aybtn, newDock); if (RenderReadyed) { Dock oldDock = (Dock)e.OldValue; //触发客户端定义的事件 aybtn.IconDChanged(oldDock, newDock); } }
OK，客户端使用
<local:AyImageButton x:Name="btnTest2" IconSource="icons/set_64.png" Background="#55B472" TextContent="AY超大按钮" IconDockPlacement="Top" Canvas.Left="212" Canvas.Top="50" HorizontalContentAlignment="Center" TextColor="#fff" IsCustomed="True" IsTabStop="False" IconWidthHorizontal="32" IconHeightHorizontal="32" IconWidthVertical="64" IconHeightVertical="64" PaddingHorizontal="18,0,0,0" WidthHorizontal="280" HeightHorizontal="80" WidthVertical="280" HeightVertical="160" TextFontSizeHorizontal="32" TextFontSizeVertical="48" MouseDown="btnTest2_MouseDown" IconDockPlacementValueChanged="IconDockPlacementValueChanged" />

后台代码（控件代码，由于dock默认值是Left，为了防止触发改变事件，我使用RenderReadyed控制默认显示时候不触发事件）：
public void IconDockPlacementValueChanged(object sender, RoutedPropertyChangedEventArgs<Dock> e) { AyImageButton aybtn = (AyImageButton)sender; Dock nDock = (Dock)e.NewValue; Dock oDock = (Dock)e.OldValue; //判断 新值 把内容变为现*原* ，颜色变成其他色 aybtn.TextContent = String.Format("现{0}原{1}", nDock.ToString(), oDock.ToString()); if (nDock == Dock.Top) { aybtn.TextColor = new SolidColorBrush(Colors.Blue); aybtn.TextFontSizeVertical = 20; } else if (nDock == Dock.Left) { aybtn.TextColor = new SolidColorBrush(Colors.Yellow); aybtn.TextFontSizeHorizontal = 32; } else if (nDock == Dock.Right) { aybtn.TextColor = new SolidColorBrush(Colors.Gold); aybtn.TextFontSizeVertical = 32; } else if (nDock == Dock.Bottom) { aybtn.TextColor = new SolidColorBrush(Colors.Pink); aybtn.TextFontSizeVertical = 20; } }
效果图：加了RenderChangedEnabled属性，用来控制按钮窗体初始化时候不执行Changed事件

讲解：RenderMode是个多值枚举，在xaml中使用英文的逗号隔开

接下来基础工作最后一步：Render模式与Dock模式混搭，暂时只是先
我们多找几张图片64*64的。增加一个下拉框调整dock，增加一组check调整RenderMode
注意：由于我使用的是Canvas布局，checkbox的按钮事件拿到ayImageButton的控件的第一个样子，如果按钮组的代码不在checkbox组的上面，是拿不到AyImageButton控件的
<StackPanel Background="Yellow" x:Name="RenderAndDock" Canvas.Left="1385" Canvas.Top="69" > <local:AyImageButton x:Name="rd2" IconSource="icons/point_64.png" TextColor="#fff" Background="YellowGreen" TextContent="积分管理" IconDockPlacement="Left" PaddingHorizontal="10,5,5,5" HorizontalContentAlignment="Left" WidthVertical="88" TabIndex="0" HeightOnlyIcon="92" WidthOnlyIcon="92" IconHeightOnlyIcon="48" IconWidthOnlyIcon="48" /> <local:AyImageButton x:Name="rd3" IconSource="icons/wjx_64.png" TextColor="#fff" Background="#86C507" TextContent="评论管理" IconDockPlacement="Left" PaddingHorizontal="10,5,5,5" HorizontalContentAlignment="Left" WidthVertical="88" TabIndex="1" HeightOnlyIcon="92" WidthOnlyIcon="92" IconHeightOnlyIcon="48" IconWidthOnlyIcon="48" /> <local:AyImageButton x:Name="rd4" IconSource="icons/house_64.png" TextColor="#fff" Background="YellowGreen" TextContent="资料库" IconDockPlacement="Left" PaddingHorizontal="10,5,5,5" HorizontalContentAlignment="Left" WidthVertical="88" TabIndex="2" HeightOnlyIcon="92" WidthOnlyIcon="92" IconHeightOnlyIcon="48" IconWidthOnlyIcon="48" /> <local:AyImageButton x:Name="rd" IconSource="icons/set_64.png" Background="#86C507" TextContent="设置" IconDockPlacement="Left" PaddingHorizontal="10,5,5,5" HorizontalContentAlignment="Left" TextColor="#fff" WidthVertical="88" TabIndex="3" HeightOnlyIcon="92" WidthOnlyIcon="92" IconHeightOnlyIcon="48" IconWidthOnlyIcon="48" /> </StackPanel> <StackPanel Canvas.Left="1343" Canvas.Top="18" x:Name="spRenderSelect" Orientation="Horizontal"> <CheckBox Tag="Icon" FontSize="16" IsChecked="True" Checked="CheckBox_Checked" Unchecked="CheckBox_Checked">显示图标</CheckBox> <CheckBox Tag="Text" FontSize="16" IsChecked="True" Checked="CheckBox_Checked" Unchecked="CheckBox_Checked">显示文本</CheckBox> <CheckBox Tag="Tips" FontSize="16" Checked="CheckBox_Checked" Unchecked="CheckBox_Checked">提示</CheckBox> </StackPanel> <ComboBox Canvas.Left="1206" Canvas.Top="17" Width="120" Height="20" x:Name="cboDockSelect" SelectionChanged="cboDockSelect_SelectionChanged"/>
接着，添加后台的事件，代码比较简单，不讲解了
private void cboDockSelect_SelectionChanged(object sender, SelectionChangedEventArgs e) { foreach (var item in RenderAndDock.Children) { AyImageButton ay = item as AyImageButton; if (ay != null) { ay.IconDockPlacement =(Dock)cboDockSelect.SelectedItem; } } }
private void CheckBox_Checked(object sender, RoutedEventArgs e) { CheckBox ck = (CheckBox)sender; //强制转换枚举 AyImageButtonRenderMode mode = (AyImageButtonRenderMode)Enum.Parse(typeof(AyImageButtonRenderMode), ck.Tag.ToString()); AyImageButtonRenderMode currRenderMode = rd.RenderMode; if (ck.IsChecked.Value) { foreach (var item in RenderAndDock.Children) { AyImageButton ay = item as AyImageButton; if (ay != null) { ay.RenderMode = ay.RenderMode | mode; } } } else { foreach (var item in RenderAndDock.Children) { AyImageButton ay = item as AyImageButton; if (ay != null) { ay.RenderMode = ay.RenderMode & (~mode); //去掉复合枚举的值，也可以使用^取异操作 } } } }
public MainWindow() { InitializeComponent(); //DOCK数据绑定 foreach (Dock mode in Enum.GetValues(typeof(Dock))) { cboDockSelect.Items.Add(mode); cboDockSelect.SelectedItem = rd.IconDockPlacement; } }
讲解一下Flags符合枚举的 添加值和减去值的方法，aaronyang总结，xaml中使用英文逗号隔开表示多值
添加值： 使用 | 或运算符，例子： 枚举值1 | 枚举值2
有值就减去，无值就增加：用 ^ 运算符 ，例子： 枚举值1 ^ 枚举值2
判断是否有值，如果有，就减去值，例子：枚举值1& (~枚举值2)
如果混搭的话，就有某些元素是否显示还是隐藏，我们拿到控件后使用FindName查找用户控件，然后设置其属性值
((TextBlock)aybtn.FindName("tbText")).Visibility = Visibility.Collapsed;
关于RenderMode变化，所以我们需要增加变化后的操作，用来控制排版和哪些显示还是隐藏
public AyImageButtonRenderMode RenderMode { get { return (AyImageButtonRenderMode)GetValue(RenderModeProperty); } set { SetValue(RenderModeProperty, value); } } // Using a DependencyProperty as the backing store for RenderMode. This enables animation, styling, binding, etc... public static readonly DependencyProperty RenderModeProperty = DependencyProperty.Register("RenderMode", typeof(AyImageButtonRenderMode), typeof(AyImageButton), new PropertyMetadata(AyImageButtonRenderMode.Icon | AyImageButtonRenderMode.Text, ButtonRenderChanged)); private static void ButtonRenderChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) { AyImageButton aybtn = (AyImageButton)d; aybtn.IconDockChanged(aybtn, aybtn.IconDockPlacement); }
