上回说道，ANode的外观绘制，今天继续动画部分。
我对ANode的各个状态做了一个小总结
| ANode 的 状态 |
| ANode 的 状态 |
| 1.普通状态（NormalStatus） 2.选中状态（SelectedStatus） 3.编辑状态（EditStatus） 4.拖动状态（DragStatus） |
| 基本动画 |
针对于这几个状态之间的变换，我采用动画的方式，逐一介绍
在介绍我们设定的各种状态前，让我们看看具体都涉及哪些动画。
动画直接写Xaml
1 <!--边框变为1--> 2 <ThicknessAnimationUsingKeyFrames 3 Storyboard.TargetProperty="(Border.BorderThickness)" 4 Storyboard.TargetName="NodeBorder"> 5 <EasingThicknessKeyFrame KeyTime="0" Value="1"/> 6 </ThicknessAnimationUsingKeyFrames>
ANode边框变小
1 <!--边框阴影变为5--> 2 <DoubleAnimationUsingKeyFrames 3 Storyboard.TargetProperty="(UIElement.Effect) 4 .(DropShadowEffect.BlurRadius)" 5 Storyboard.TargetName="NodeBackground"> 6 <EasingDoubleKeyFrame KeyTime="0" Value="5"/> 7 </DoubleAnimationUsingKeyFrames>
阴影缩小为5
1 <!--输入框隐藏--> 2 <DoubleAnimationUsingKeyFrames 3 Storyboard.TargetProperty="(UIElement.Opacity)" 4 Storyboard.TargetName="NodeTextInput"> 5 <EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="0"/> 6 </DoubleAnimationUsingKeyFrames>
输入文本框隐藏
1 <!--创建工具栏隐藏--> 2 <DoubleAnimationUsingKeyFrames 3 Storyboard.TargetProperty="(UIElement.Opacity)" 4 Storyboard.TargetName="NewFriend"> 5 <EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="0"/> 6 </DoubleAnimationUsingKeyFrames> 7 <DoubleAnimationUsingKeyFrames 8 Storyboard.TargetProperty="(UIElement.Opacity)" 9 Storyboard.TargetName="NewSubNode"> 10 <EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="0"/> 11 </DoubleAnimationUsingKeyFrames>
工具栏隐藏
这里所用的隐藏，并不是设置Visible，而是将透明度变为0，只写一个KeyTime，
即可在任何状态下直接变成你想要的状态。
| 动画 的 组合 |
大概，需要的动画，就差不多写完了，在不同的状态下，只要改变参数就可以了。
现在将这些动画，分配给各个状态。在我们想要ANode变成什么状态时，就播放相应的动画。
现在就开始设置各个状态的动画面板（StoryBoard）
1.普通状态
，普通状态下，控件边框缩小为1，阴影也缩小为5，隐藏工具栏等
1 <!--正常状态--> 2 <Storyboard x:Key="NormalStatus"> 3 <!--边框变为1--> 4 <ThicknessAnimationUsingKeyFrames Storyboard.TargetProperty="(Border.BorderThickness)" Storyboard.TargetName="NodeBorder"> 5 <EasingThicknessKeyFrame KeyTime="0" Value="1"/> 6 </ThicknessAnimationUsingKeyFrames> 7 <!--边框阴影变为5--> 8 <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Effect).(DropShadowEffect.BlurRadius)" Storyboard.TargetName="NodeBackground"> 9 <EasingDoubleKeyFrame KeyTime="0" Value="5"/> 10 </DoubleAnimationUsingKeyFrames> 11 <!--输入框隐藏--> 12 <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" 13 Storyboard.TargetName="NodeTextInput"> 14 <EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="0"/> 15 </DoubleAnimationUsingKeyFrames> 16 <!--创建工具栏隐藏--> 17 <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" 18 Storyboard.TargetName="NewFriend"> 19 <EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="0"/> 20 </DoubleAnimationUsingKeyFrames> 21 <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" 22 Storyboard.TargetName="NewSubNode"> 23 <EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="0"/> 24 </DoubleAnimationUsingKeyFrames> 25 </Storyboard>
2.选中状态：边框 4 阴影 10 工具栏出现
1 <!--选中状态--> 2 <Storyboard x:Key="SelectedStatus"> 3 <!--边框变为4--> 4 <ThicknessAnimationUsingKeyFrames Storyboard.TargetProperty="(Border.BorderThickness)" 5 Storyboard.TargetName="NodeBorder"> 6 <EasingThicknessKeyFrame KeyTime="0" Value="4"/> 7 </ThicknessAnimationUsingKeyFrames> 8 <!--边框阴影变为10--> 9 <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Effect).(DropShadowEffect.BlurRadius)" 10 Storyboard.TargetName="NodeBackground"> 11 <EasingDoubleKeyFrame KeyTime="0" Value="10"/> 12 </DoubleAnimationUsingKeyFrames> 13 <!--输入框隐藏--> 14 <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" 15 Storyboard.TargetName="NodeTextInput"> 16 <EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="0"/> 17 </DoubleAnimationUsingKeyFrames> 18 <!--创建工具栏显现--> 19 <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" 20 Storyboard.TargetName="NewFriend"> 21 <EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="1"/> 22 </DoubleAnimationUsingKeyFrames> 23 <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" 24 Storyboard.TargetName="NewSubNode"> 25 <EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="1"/> 26 </DoubleAnimationUsingKeyFrames> 27 </Storyboard>
3.编辑状态：边框 4 阴影 10 隐藏工具栏 显示输入框
1 <!--编辑状态--> 2 <Storyboard x:Key="EditStatus"> 3 <!--鼠标变为手--> 4 <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(FrameworkElement.Cursor)" Storyboard.TargetName="ANodeObject"> 5 <DiscreteObjectKeyFrame KeyTime="0"> 6 <DiscreteObjectKeyFrame.Value> 7 <Cursor>Hand</Cursor> 8 </DiscreteObjectKeyFrame.Value> 9 </DiscreteObjectKeyFrame> 10 </ObjectAnimationUsingKeyFrames> 11 <!--边框变为4--> 12 <ThicknessAnimationUsingKeyFrames Storyboard.TargetProperty="(Border.BorderThickness)" 13 Storyboard.TargetName="NodeBorder"> 14 <EasingThicknessKeyFrame KeyTime="0" Value="4"/> 15 </ThicknessAnimationUsingKeyFrames> 16 <!--边框阴影变为10--> 17 <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Effect).(DropShadowEffect.BlurRadius)" 18 Storyboard.TargetName="NodeBackground"> 19 <EasingDoubleKeyFrame KeyTime="0" Value="10"/> 20 </DoubleAnimationUsingKeyFrames> 21 <!--输入框显现--> 22 <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" 23 Storyboard.TargetName="NodeTextInput"> 24 <EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="1"/> 25 </DoubleAnimationUsingKeyFrames> 26 <!--创建工具栏隐藏--> 27 <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" 28 Storyboard.TargetName="NewFriend"> 29 <EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="0"/> 30 </DoubleAnimationUsingKeyFrames> 31 <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" 32 Storyboard.TargetName="NewSubNode"> 33 <EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="0"/> 34 </DoubleAnimationUsingKeyFrames> 35 </Storyboard>
4.拖动状态：比选中状态少一个工具栏而已
1 <!--拖动状态--> 2 <Storyboard x:Key="DragStatus"> 3 <!--鼠标变为移动--> 4 <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(FrameworkElement.Cursor)" Storyboard.TargetName="ANodeObject"> 5 <DiscreteObjectKeyFrame KeyTime="0"> 6 <DiscreteObjectKeyFrame.Value> 7 <Cursor>SizeAll</Cursor> 8 </DiscreteObjectKeyFrame.Value> 9 </DiscreteObjectKeyFrame> 10 </ObjectAnimationUsingKeyFrames> 11 <!--边框变为4--> 12 <ThicknessAnimationUsingKeyFrames Storyboard.TargetProperty="(Border.BorderThickness)" Storyboard.TargetName="NodeBorder"> 13 <EasingThicknessKeyFrame KeyTime="0" Value="4"/> 14 </ThicknessAnimationUsingKeyFrames> 15 <!--边框阴影变为10--> 16 <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Effect).(DropShadowEffect.BlurRadius)" Storyboard.TargetName="NodeBackground"> 17 <EasingDoubleKeyFrame KeyTime="0" Value="10"/> 18 </DoubleAnimationUsingKeyFrames> 19 <!--输入框隐藏--> 20 <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" 21 Storyboard.TargetName="NodeTextInput"> 22 <EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="0"/> 23 </DoubleAnimationUsingKeyFrames> 24 <!--创建工具栏隐藏--> 25 <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" 26 Storyboard.TargetName="NewFriend"> 27 <EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="0"/> 28 </DoubleAnimationUsingKeyFrames> 29 <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" 30 Storyboard.TargetName="NewSubNode"> 31 <EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="0"/> 32 </DoubleAnimationUsingKeyFrames> 33 </Storyboard>
这样，状态动画就做完了，放在<UserControl.Resources>中，作为动画资源，等待调用。
下面，这些状态的触发，可以在Xaml中设置，也可以在代码中启动，将不需要在代码中启动
的动画添加到触发器<UserControl.Triggers>当中。
1 <UserControl.Triggers> 2 <!--启动时设置为正常状态--> 3 <EventTrigger RoutedEvent="FrameworkElement.Loaded"> 4 <BeginStoryboard x:Name="OnLoaded_BeginStoryboard" 5 Storyboard="{StaticResource NormalStatus}"/> 6 </EventTrigger> 7 <!--鼠标在NodeText上抬起时设置为编辑状态--> 8 <EventTrigger RoutedEvent="Mouse.PreviewMouseUp" SourceName="NodeTextInput"> 9 <BeginStoryboard x:Name="EditStatus_BeginStoryboard" 10 Storyboard="{StaticResource EditStatus}"/> 11 </EventTrigger> 12 <!--NodeTextInput失去焦点时，变成普通状态--> 13 <EventTrigger RoutedEvent="Keyboard.LostKeyboardFocus" SourceName="NodeTextInput"> 14 <BeginStoryboard Storyboard="{StaticResource NormalStatus}"/> 15 </EventTrigger> 16 </UserControl.Triggers>
其实最后一个失去焦点的动画，可以不写在Xaml中，因为，ANode失去焦点有几种情况，
主要发生在UI的事件中。
| 完整 的 代码 |
那么，目前的ANode Xaml部分就介绍完了，如果后续有需要，可以继续在这个结构基础上
添加即可。
贴一个完整的代码。
