对不起我的英语不好。我是 WPF 的新手,我有一个问题。我想在触发Canvas
时更改包含路径(图像)的视觉样式。isMouseOver
脚步:
- 将画布放到窗口
- 包含路径
结果:
<Canvas x:Name="mycanvas" Width="76" Height="76" Clip="F1 M 0,0L 76,0L 76,76L 0,76L 0,0">
<Path Width="40" Height="30" Canvas.Left="18" Canvas.Top="23" Stretch="Fill" Fill="#FF000000" Data="F1 M 18,23L 58,23L 58,53L 18,53L 18,23 Z M 54,31L 22,31L 22,49L 54,49L 54,31 Z M 45,38L 45,42L 31,42L 31,38L 45,38 Z "/>
</Canvas>
然后我将画布与样式结合起来,如果出现Button
的话,用白色填充“路径” 。isMouseOver
我的风格:
<Style x:Key="ButtonStyle1" TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Canvas x:Name="mycanvas" Clip="F1 M 0,0L 76,0L 76,76L 0,76L 0,0">
<Path x:Name="path" Width="40" Canvas.Top="23" Stretch="Fill" Canvas.Left="18" Height="30" Fill="#FF000000" Data="F1 M 18,23L 58,23L 58,53L 18,53L 18,23 Z M 54,31L 22,31L 22,49L 54,49L 54,31 Z M 45,38L 45,42L 31,42L 31,38L 45,38 Z "/>
</Canvas>
<ControlTemplate.Triggers>
<Trigger Property="IsFocused" Value="True"/>
<Trigger Property="IsDefaulted" Value="True"/>
<Trigger Property="IsMouseOver" Value="True" SourceName="mycanvas">
<Setter Property="Fill" TargetName="path" Value="White"/>
</Trigger>
<Trigger Property="IsPressed" Value="True"/>
<Trigger Property="IsEnabled" Value="False"/>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
但IsMouseOver
仅当鼠标穿过图像(“路径”)表面时才有效。但是图像表面很小并且包含中断。我怎么解决这个问题?
