我正在尝试在Expression Studio中为silverlight创建一个按钮模板。 Button是一个基本矩形,里面有另一个矩形,低透明度表示按钮上的“光泽”。按钮工作正常,除非高度改变,我需要“光泽”矩形的高度也自动增加,以保持其正常的宽高比。无论如何这样做?我可以将高度设置为另一个的“50%”吗?
谢谢,
以下是我的模板代码:
<Style x:Key="CloseButtonBlack" TargetType="Button">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Grid x:Name="grid">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualStateGroup.Transitions>
<VisualTransition GeneratedDuration="0:0:0.2"/>
<VisualTransition GeneratedDuration="0" To="Pressed"/>
</VisualStateGroup.Transitions>
<VisualState x:Name="Disabled">
<Storyboard>
<DoubleAnimation Duration="0" To="0.495" Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="grid" d:IsOptimized="True"/>
</Storyboard>
</VisualState>
<VisualState x:Name="Normal"/>
<VisualState x:Name="MouseOver">
<Storyboard>
<ColorAnimation Duration="0" To="#FF333333" Storyboard.TargetProperty="(Shape.Fill).(SolidColorBrush.Color)" Storyboard.TargetName="Button" d:IsOptimized="True"/>
</Storyboard>
</VisualState>
<VisualState x:Name="Pressed">
<Storyboard>
<ColorAnimation Duration="0" To="#FF434343" Storyboard.TargetProperty="(Shape.Fill).(SolidColorBrush.Color)" Storyboard.TargetName="Button" d:IsOptimized="True"/>
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<Rectangle x:Name="Button" Fill="Black" Stroke="#FF2D2D2D"/>
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Content="X"/>
<Rectangle x:Name="Gloss" Fill="White" Height="12" Margin="1, 1, 1, 0" Stroke="#FF2D2D2D" VerticalAlignment="Top" Opacity="0.25"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
答案 0 :(得分:1)
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Rectangle x:Name="Button" Grid.RowSpan="2" .../>
<ContentPresenter Grid.RowSpan="2" .../>
<Rectangle x:Name="Gloss" Grid.Row="1" .../>
<!-- Remove the Height="12" from this element -->
</Grid>
这将形成一个2行网格,其中每行占总高度的50%,并将“Gloss”矩形放在第二行,占据网格的下半部分,同时将“Button”矩形拉伸到整个高度。
