WPF ControlTemplate 仿QQ概念版CheckBox

QQ概念版是腾讯用WPF精心打造的创新型IM产品，界面做的自然是比较不错，只不过实现的功能太少，并且对运行的平台限制太多（只能是Windows7），现在已经没什么消息了。

先贴图：



控件选中后弹出的勾用图片来代替，并有动画效果。

下面为CheckBox的Style代码：

<Style TargetType="{x:Type CheckBox}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="CheckBox">
<StackPanel Orientation="Horizontal">
<Border BorderBrush="#0C202C" Background="Transparent"
CornerRadius="3" BorderThickness="2"
Width="22" Height="22" ClipToBounds="False">
<Image x:Name="checkImg" Source="images/check.png" Width="24" HorizontalAlignment="Center"
VerticalAlignment="Center" RenderTransformOrigin="0.5,0.5">
<Image.RenderTransform>
<TransformGroup>
<ScaleTransform ScaleX="0" ScaleY="0"/>
<RotateTransform Angle="0"/>
</TransformGroup>
</Image.RenderTransform>
</Image>
</Border>
<Border Padding="5,0,0,0">
<ContentPresenter VerticalAlignment="Center" Content="{TemplateBinding Property=ContentControl.Content}"/>
</Border>
</StackPanel>
