Question

我想为我的GridSplitter设置样式，例如在其上添加点（如http://msdn.microsoft.com/en-us/library/aa970265.aspx上所示）。

我还想在mouseOver上更改gridsplitter颜色，或者应用Aero Theme。

<Style x:Key="GridSplitterStyle1" TargetType="{x:Type GridSplitter}">
  <Setter Property="Background"
          Value="{DynamicResource {x:Static SystemColors.ControlBrushKey}}"/>
  <Setter Property="PreviewStyle">
    <Setter.Value>
      <Style>
        <Setter Property="Control.Template">
          <Setter.Value>
            <ControlTemplate>
              <Rectangle Fill="#80000000"/>
            </ControlTemplate>
          </Setter.Value>
        </Setter>
      </Style>
    </Setter.Value>
  </Setter>
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type GridSplitter}">
        <Border Background="{TemplateBinding Background}"
                BorderBrush="{TemplateBinding BorderBrush}"
                BorderThickness="{TemplateBinding BorderThickness}"/>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>

<GridSplitter x:Name="gridSplitterTreeNodes" Width="10"
              BorderThickness="1,0" Cursor="SizeWE"
              RenderTransformOrigin="-1.2,0.507" ShowsPreview="True" 
              Style="{DynamicResource GridSplitterStyle1}">
  <GridSplitter.Background>
    <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
      <GradientStop Color="#FFE3EFFF" Offset="0"/>
      <GradientStop Color="#FFAFD2FF" Offset=".45"/>
    </LinearGradientBrush>
  </GridSplitter.Background>
</GridSplitter>

Answer 1

主要是为了我将来的参考，这里是一个垂直网格分割器，它具有一个按钮的圆形形状（但没有对鼠标悬停做出正确反应）：

<GridSplitter Grid.Column="1" VerticalAlignment="Stretch" HorizontalAlignment="Center" Width="8">
    <GridSplitter.Template>
        <ControlTemplate TargetType="{x:Type GridSplitter}">
            <Grid>
                <Button Content="⁞" />
                <Rectangle Fill="#00FFFFFF" />
            </Grid>
        </ControlTemplate>
    </GridSplitter.Template>
</GridSplitter>

水平分割器只能使用“····”作为按钮的内容。

<GridSplitter x:Name="gridSplitterTreeNodes" Width="5" BorderThickness="1,0" 
     Cursor="SizeWE" RenderTransformOrigin="-1.2,0.507" ShowsPreview="True"
     Style="{DynamicResource GridSplitterStyle1}">
  <GridSplitter.Background>
    <ImageBrush ImageSource="Images\gripDots.png" TileMode="FlipXY" 
                Stretch="UniformToFill"/>
  </GridSplitter.Background>
</GridSplitter>

Answer 3

在不丢失鼠标事件的情况下，向GridSplitter添加“抓手”按钮/图形的另一种方法是在分割器顶部使用简单的标签。

    <GridSplitter Grid.Column="1" Width="5" HorizontalAlignment="Stretch" Background="Gray"/>

    <Label Grid.Column="1" Content="⁞" Foreground="White" VerticalAlignment="Center" FontSize="26" FontWeight="Bold" IsHitTestVisible="False"/>

确保GridSplitter和Label位于同一列中，并且标签中设置了IsHitTestVisible = False。

针对Burton Radons的回答，我个人更喜欢这种样式：

<GridSplitter
  Width="8"
  HorizontalAlignment="Stretch"
  VerticalAlignment="Stretch">

  <GridSplitter.Template>
    <ControlTemplate TargetType="{x:Type GridSplitter}">
      <Grid>
        <TextBlock
          HorizontalAlignment="Center"
          VerticalAlignment="Center"
          Text="⁞" />
        <Rectangle Fill="#00FFFFFF" />
      </Grid>
    </ControlTemplate>
  </GridSplitter.Template>
</GridSplitter>

此实现产生了相同的美学效果，同时还保持了功能。

对于其他类型的样式，您可以执行以下操作。

产生漂亮的重叠样式。 Gridsplitter将左右内容重叠。

<Grid>
     <Grid.ColumnDefinitions>
         <ColumnDefinition Width="*"/>
         <ColumnDefinition Width="1"/>
         <ColumnDefinition Width="*"/>
     </Grid.ColumnDefinitions>

     <Border Grid.Column="0" Background="#777"/>

     <GridSplitter
         Grid.Column="1"
         HorizontalAlignment="Stretch" 
         ResizeDirection="Columns"
         ResizeBehavior="PreviousAndNext"
         Panel.ZIndex="2">
           <GridSplitter.Template>

               <ControlTemplate TargetType="{x:Type GridSplitter}">

                   <Grid>
                        <Rectangle IsHitTestVisible="False" Fill="Black"/>
                        <Border
                           Background="White"
                           Width="25" Height="25" c 
                           CornerRadius="25" Margin="-13 0">
                           <Path Stroke="Black" StrokeThickness="0.5" Width="17" Height="7" Data="m 4.4549201,1048.4664 -4.33056515,1.9095 4.33056515,1.9094 0,-3.8189 z m 3.0901599,0 0,3.8189 4.330565,-1.9094 -4.330565,-1.9095 z m -3.2239449,0.2053 0,3.4083 -3.86518514,-1.7041 3.86518514,-1.7042 z m 3.3577349,0 3.865185,1.7042 -3.865185,1.7041 0,-3.4083 z" Stretch="Fill"/>
                        </Border>
                   </Grid>

                </ControlTemplate>

                </GridSplitter.Template>

     </GridSplitter>

     <Border Grid.Column="2" Background="#777"/>

</Grid>
