在我当前的项目中,我有这个 XAML 文件,我在其中定义了必须应用于不同类型的自定义小部件的视觉样式。
例如,'DirectLineButton'(继承自 WPF 的 Button 的自定义类)的样式如下:
<Style x:Key="DirectLineButtonTemplate" TargetType="{x:Type View:DirectLineButton}">
<Setter Property="SnapsToDevicePixels" Value="true"/>
<Setter Property="OverridesDefaultStyle" Value="true"/>
<Setter Property="MinHeight" Value="23"/>
<Setter Property="MinWidth" Value="75"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="MyBorder"
CornerRadius="2"
BorderThickness="2"
Background="Gold"
BorderBrush="Gray">
<ContentPresenter Margin="2"
HorizontalAlignment="Center"
VerticalAlignment="Center"
RecognizesAccessKey="True"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="View:DirectLineButton.State" Value="DirectLineAvailable">
<Setter TargetName="MyBorder" Property="Background" Value="Gold"/>
</Trigger>
<Trigger Property="View:DirectLineButton.State" Value="DirectLineIdle">
<Setter TargetName="MyBorder" Property="Background" Value="Silver"/>
</Trigger>
<Trigger Property="View:DirectLineButton.State" Value="DirectLineBusy">
<Setter TargetName="MyBorder" Property="Background" Value="Green"/>
</Trigger>
<Trigger Property="View:DirectLineButton.State" Value="DirectLineCalled">
<Setter TargetName="MyBorder" Property="Background" Value="LightBlue"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
现在,我需要通过定义 Rectangle 的样式来复制这个想法。不幸的是,当我尝试为矩形定义 ControlTemplate 时,WPF 会标记一条错误消息,您能建议解决此问题的方法吗?请参阅下面我尝试尝试的代码:
<Style x:Key="MyRectangleTemplate" TargetType="{x:Type Rectangle}">
<Setter Property="SnapsToDevicePixels" Value="true"/>
<Setter Property="OverridesDefaultStyle" Value="true"/>
<Setter Property="MinHeight" Value="23"/>
<Setter Property="MinWidth" Value="75"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Rectangle}">
<Border x:Name="MyBorder"
CornerRadius="2"
BorderThickness="2"
Background="Gold"
BorderBrush="Gray">
<ContentPresenter Margin="2"
HorizontalAlignment="Center"
VerticalAlignment="Center"
RecognizesAccessKey="True"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="View:DirectLineButton.State" Value="DirectLineAvailable">
<Setter TargetName="MyBorder" Property="Background" Value="Gold"/>
</Trigger>
<Trigger Property="View:DirectLineButton.State" Value="DirectLineIdle">
<Setter TargetName="MyBorder" Property="Background" Value="Silver"/>
</Trigger>
<Trigger Property="View:DirectLineButton.State" Value="DirectLineBusy">
<Setter TargetName="MyBorder" Property="Background" Value="Green"/>
</Trigger>
<Trigger Property="View:DirectLineButton.State" Value="DirectLineCalled">
<Setter TargetName="MyBorder" Property="Background" Value="LightBlue"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
提前致谢!
