wpf-toolbar

项目中新建文件夹 Images，资源管理器中把图片拷贝进去，项目中图片属性设置 build action 为 Resource do not copy 就可以引用了。

<ToolBarTray DockPanel.Dock="Top">
    <ToolBar>
        <Button ToolTip="打开测量界面" Name="tb_measurement" Click="tb_measurement_Click">
            <StackPanel Orientation="Vertical">
                <Image Source="/MRLGauger;component/Images/measure_40.png" />
                <TextBlock Margin="0,2,0,0" HorizontalAlignment="Center">测量</TextBlock>
            </StackPanel>
        </Button>
        <Button ToolTip="打开编程界面" Name="tb_program" Click="tb_program_Click">
            <StackPanel Orientation="Vertical">
                <Image Source="/MRLGauger;component/Images/measure_40.png" />
                <TextBlock Margin="0,2,0,0" HorizontalAlignment="Center">编程</TextBlock>
            </StackPanel>
        </Button>
        <Button Command="Save" Content="Save" />
    </ToolBar>
</ToolBarTray>

动态切换图标和文字

<Window x:Class="MRLGauger.MainWindow"

        mc:Ignorable="d" Loaded="Window_Loaded"
        Title="MRLGauger" Height="768" Width="1024" WindowStartupLocation="CenterScreen" Closed="Window_Closed">
<Window.Resources>
    <StackPanel x:Key="IMG_Auto" Orientation="Vertical">
        <Image Source="/MRLGauger;component/Images/auto_40.png" />
        <TextBlock Margin="0,2,0,0" HorizontalAlignment="Center">自动</TextBlock>
    </StackPanel>
    <StackPanel x:Key="IMG_Manual" Orientation="Vertical">

        <TextBlock Margin="0,2,0,0" x:Name="tb_textBlock_manual" HorizontalAlignment="Center">手动</TextBlock>
    </StackPanel>
</Window.Resources>
...


private void tb_auto_Click(object sender, RoutedEventArgs e)
{
    // 1 自动(默认)， 2 手动
    if (measureDisplay.operate_type == 1)
    {
        measureDisplay.operate_type = 2;
        ((Button)sender).Content = FindResource("IMG_Manual");
    }
    else if (measureDisplay.operate_type == 2)
    {
        measureDisplay.operate_type = 1;
        ((Button)sender).Content = FindResource("IMG_Auto");
    }

    tb_textBlock_manual.Text = "文字";

}

设置无效

<Button ToolTip="开始自动测量" Name="tb_start" Click="tb_start_Click">
    <StackPanel Orientation="Vertical">
        <Image x:Name="img_start" Source="{DynamicResource src_img_start}" />
        <TextBlock Margin="0,2,0,0" HorizontalAlignment="Center">工步开始</TextBlock>
    </StackPanel>
</Button>

// 设置灰度图
{
    ImageSource isource = img_start.Source;
    FormatConvertedBitmap fcb = new FormatConvertedBitmap((BitmapSource)isource, PixelFormats.Gray32Float, null, 0);
    img_start.Source = fcb;
    img_start.OpacityMask = new ImageBrush(isource);
}

// 回复原图
img_start.Source = FindResource("src_img_start") as BitmapImage;
