我正在尝试创建一个GridSplitter
主要是不透明的,然后在鼠标悬停时,动画变得完全可见。这是我尝试过的:
风格:
<Style x:Key="SplitterStyle" TargetType="{x:Type GridSplitter}">
<Setter Property="Opacity" Value="0.2" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type GridSplitter}">
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="Opacity" To="1" Duration="0:0:0.2" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="Opacity" Duration="0:0:0.3" />
</Storyboard>
</BeginStoryboard>
</Trigger.ExitActions>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
GridSplitter
:
<GridSplitter
ResizeDirection="Columns"
Grid.Column="0"
Background="Red"
VerticalAlignment="Stretch"
Width="4"
Style="{StaticResource SplitterStyle}" />
我检查了 MSDN,GridSplitter 具有我正在使用的所有属性,所以看起来应该没问题,但也许我忽略了一些明显的东西?
编辑:
是否可以将 GridSplitter 放入另一个元素中?我改变了我的风格:
<Style x:Key="SplitterStyle" TargetType="{x:Type Border}">
<Setter Property="Opacity" Value="0.2" />
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="Opacity" To="1" Duration="0:0:0.2" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="Opacity" Duration="0:0:0.3" />
</Storyboard>
</BeginStoryboard>
</Trigger.ExitActions>
</Trigger>
</Style.Triggers>
</Style>
然后,我将 GridSplitter 放入 Border 并将样式应用于边框,而不是:
<Border
Style="{StaticResource SplitterStyle}"
Background="{StaticResource WindowBorderBrush}"
VerticalAlignment="Stretch"
Width="4"
Grid.Column="0"
HorizontalAlignment="Right">
<GridSplitter ResizeDirection="Columns" Background="Red" ResizeBehavior="CurrentAndNext"/>
</Border>
边框效果很好!但是现在,找不到 GridSplitter(没有显示红色背景,当我将鼠标悬停在边框上时光标不会改变,并且没有任何东西可以拖动来调整大小)。为什么是这样?
编辑:
好的,我发现我必须为GridSplitter
. 另外,我将背景更改为GridSplitter
透明,因为我从未打算使用红色。现在,它显示并且看起来很棒,但它实际上仍然没有调整任何东西:P 我如何让它真正有用?
