  • WPF中Button的四种状态

    在WPF中使用Button有时候需要让button响应鼠标的几种状态，虽然它本身也有响应的处理，但有时希望在它上面贴图片，在几种状态时可以随状态切换图片。此处用的是资源字典

    类似：

     1 <Style x:Key="ButtonStyle34" TargetType="{x:Type Button}">
     2         <Setter Property="Template">
     3             <Setter.Value>
     4                 <ControlTemplate TargetType="{x:Type Button}">
     5                     <StackPanel Orientation="Horizontal" Background="Transparent" Margin="0,0,0,0" >
     6                         <Image Name="ImgBtnBg3" Margin="0,0,0,2" Source="/Resources/Res/Delete_I.png" Stretch="Fill" Width="54"/>
     7                     </StackPanel>
     8                     <ControlTemplate.Triggers>
     9                         <Trigger Property="IsMouseOver" Value="True">
    10                             <Setter Property="Source" Value="/Resources/Res/Geng_II.png" TargetName="ImgBtnBg3"/>
    11                         </Trigger>
    12                         <Trigger Property="IsPressed" Value="True">
    13                             <Setter Property="Source" Value="/Resources/Res/Geng_III.png" TargetName="ImgBtnBg3"/>
    14                         </Trigger>
    15                         <Trigger Property="IsEnabled" Value="False">
    16                             <Setter Property="Source" Value="/Resources/Res/Delete_I.png" TargetName="ImgBtnBg3"/>
    17                         </Trigger>
    18                     </ControlTemplate.Triggers>
    19                 </ControlTemplate>
    20             </Setter.Value>
    21         </Setter>
    22 
    23     </Style>

    在页面：

    <Button Style="{DynamicResource ButtonStyle34}" >

    不光只有Button是这样其实很多控件都可以这样的比如 TabControl 里的 TabItem 也可以做成类似状态，基本上资源字典和button一样

     <Style x:Key="TabItemStyle6" TargetType="{x:Type TabItem}">
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="{x:Type TabItem}">
                            <StackPanel Orientation="Horizontal" Margin="0,0,0,0" >
                                <Image Name="ImgBtnBg3" Source="/Resources/VLCIcon/RssIcon/LocalPlay_I.png" Stretch="Fill" Width="144"/>
                            </StackPanel>
                            <ControlTemplate.Triggers>
                                            <Trigger Property="IsMouseOver" Value="True">
                                                <Setter Property="Source" Value="/Resources/VLCIcon/RssIcon/LocalPlay_II.png" TargetName="ImgBtnBg3"/>
                                            </Trigger>
                                            <Trigger Property="IsSelected" Value="True">
                                                <Setter Property="Source" Value="/Resources/VLCIcon/RssIcon/LocalPlay_III.png" TargetName="ImgBtnBg3"/>
                                            </Trigger>
                                            <Trigger Property="IsEnabled" Value="False">
                                                <Setter Property="Source" Value="/Resources/VLCIcon/RssIcon/LocalPlay_III.png" TargetName="ImgBtnBg3"/>
                                            </Trigger>
                            </ControlTemplate.Triggers>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>

    页面

    <TabItem Header="Tab1" Style="{DynamicResourceTabItemStyle6}" >
