本文介绍使用第三方开源库 Dragablz 实现可拖拽的 TabControl,本文代码效果图如下:

可拖拽的 TabControl

2. 代码实现

使用 .Net Framework 4.8 创建名为 “TabMenu2” 的WPF模板项目,添加三个Nuget库:MaterialDesignThemes、MaterialDesignColors 和 Dragablz,其中 TabControl 的拖拽功能是由 Dragablz 库实现的。

以下为三个库具体版本:

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="Dragablz" version="0.0.3.203" targetFramework="net45" />
  <package id="MaterialDesignColors" version="1.2.3-ci948" targetFramework="net48" />
  <package id="MaterialDesignThemes" version="3.1.0-ci948" targetFramework="net48" />
</packages>

解决方案主要文件目录组织结构:

  • TabMenu2
    • App.xaml
    • MainWindow.xaml
      • MainWIndow.xaml.cs

注:站长尝试使用 .NET CORE 3.1 创建WPF项目,但 Dragablz 库暂时未提供 .NET CORE 的版本。想着自己编译 Dragablz 的 .NET CORE 版本,奈何功力不够,改了一些源码,最后放弃了。文中代码及文末给出的 Demo 运行程序需要在 .NET Framework 4.0 运行时环境下运行,想尝试编译 Dragablz 库的朋友可在文末给出的链接中下载编译。

2.1 引入样式

文件【App.xaml】,在 StartupUri 中设置启动的视图【MainWindow.xaml】,并在【Application.Resources】节点增加 MaterialDesignThemes 和 Dragablz 库的样式文件:

<Application x:Class="TabMenu2.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:dragablz="clr-namespace:Dragablz;assembly=Dragablz"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <!-- primary color -->
                <ResourceDictionary>
                    <!-- include your primary palette -->
                    <ResourceDictionary.MergedDictionaries>
                        <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/MaterialDesignColor.purple.xaml" />
                    </ResourceDictionary.MergedDictionaries>

                    <!--
                            include three hues from the primary palette (and the associated forecolours).
                            Do not rename, keep in sequence; light to dark.
                        -->
                    <SolidColorBrush x:Key="PrimaryHueLightBrush" Color="{StaticResource Primary100}"/>
                    <SolidColorBrush x:Key="PrimaryHueLightForegroundBrush" Color="{StaticResource Primary100Foreground}"/>
                    <SolidColorBrush x:Key="PrimaryHueMidBrush" Color="{StaticResource Primary500}"/>
                    <SolidColorBrush x:Key="PrimaryHueMidForegroundBrush" Color="{StaticResource Primary500Foreground}"/>
                    <SolidColorBrush x:Key="PrimaryHueDarkBrush" Color="{StaticResource Primary700}"/>
                    <SolidColorBrush x:Key="PrimaryHueDarkForegroundBrush" Color="{StaticResource Primary700Foreground}"/>
                </ResourceDictionary>

                <!-- secondary colour -->
                <ResourceDictionary>
                    <!-- include your secondary pallette -->
                    <ResourceDictionary.MergedDictionaries>
                        <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/MaterialDesignColor.purple.xaml" />
                    </ResourceDictionary.MergedDictionaries>

                    <!-- include a single secondary accent color (and the associated forecolour) -->
                    <SolidColorBrush x:Key="SecondaryAccentBrush" Color="{StaticResource Accent200}"/>
                    <SolidColorBrush x:Key="SecondaryAccentForegroundBrush" Color="{StaticResource Accent200Foreground}"/>
                </ResourceDictionary>

                <!-- Include the Dragablz Material Design style -->
                <ResourceDictionary Source="pack://application:,,,/Dragablz;component/Themes/materialdesign.xaml"/>
                <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />
            </ResourceDictionary.MergedDictionaries>

            <!-- tell Dragablz tab control to use the Material Design theme -->
            <Style TargetType="{x:Type dragablz:TabablzControl}" BasedOn="{StaticResource MaterialDesignTabablzControlStyle}" />
        </ResourceDictionary>
    </Application.Resources>
</Application>

2.2 演示窗体布局

文件【MainWindow.xaml】,引入 MaterialDesignThemes 和 Dragablz 库的命名空间,【dragablz:TabablzControl】为 Dragablz 库封装的 TabControl,使用方式和原生控件类似,单项标签依然使用 TabItem,使用起来很简单,源码如下:

<Window x:Class="TabMenu2.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:dragablz="clr-namespace:Dragablz;assembly=Dragablz"
        mc:Ignorable="d"
        Height="600" Width="1080" ResizeMode="NoResize" WindowStartupLocation="CenterScreen" 
        MouseLeftButtonDown="Window_MouseLeftButtonDown" WindowStyle="None">
    <Grid>
        <Grid Height="60" VerticalAlignment="Top" Background="#FF9C27B0">
            <TextBlock Text="Dotnet9.com:可拖拽TabControl" Foreground="White" HorizontalAlignment="Center" VerticalAlignment="Center" FontSize="22" FontFamily="Champagne & Limousines" />
            <Button HorizontalAlignment="Right" VerticalAlignment="Center" Background="{x:Null}" BorderBrush="{x:Null}" Click="Close_Click">
                <materialDesign:PackIcon Kind="Close"/>
            </Button>
        </Grid>
        <Grid Margin="0 60 0 0">
            <dragablz:TabablzControl>
                <dragablz:TabablzControl.InterTabController>
                    <dragablz:InterTabController/>
                </dragablz:TabablzControl.InterTabController>
                <TabItem Header="首页">
                    <Grid>
                        <Grid.RowDefinitions>
                            <RowDefinition Height="50"/>
                            <RowDefinition Height="*"/>
                        </Grid.RowDefinitions>
                        <TextBlock FontSize="30" HorizontalAlignment="Center" VerticalAlignment="Center">
                            <Run Text="欢迎访问Dotnet9的博客:"/>
                            <Hyperlink Click="ShowWeb_Click" Tag="https://dotnet9.com">https://dotnet9.com</Hyperlink>
                        </TextBlock>

                    </Grid>
                </TabItem>
                <TabItem Header="设计">
                    <Grid>

                            <RowDefinition Height="50"/>
                            <RowDefinition Height="*"/>
                        </Grid.RowDefinitions>
                        <TextBlock Text="为用户体验服务!" FontSize="30" HorizontalAlignment="Center" VerticalAlignment="Center"/>
                        <WebBrowser Grid.Row="1" Margin="5" Source="https://dotnet9.com"/>
                    </Grid>
                </TabItem>
                <TabItem Header="帮助">
                    <Grid>
                        <Grid.RowDefinitions>
                            <RowDefinition Height="50"/>
                            <RowDefinition Height="*"/>
                        </Grid.RowDefinitions>
                        <TextBlock FontSize="30" HorizontalAlignment="Center" VerticalAlignment="Center">
                            <Run Text="问答社区:"/>
                            <Hyperlink Click="ShowWeb_Click" Tag="https://dotnet9.com/questions-and-answers">https://dotnet9.com/questions-and-answers</Hyperlink>
                        </TextBlock>
                        <WebBrowser Grid.Row="1" Margin="5" Source="https://dotnet9.com/questions-and-answers"/>
                    </Grid>
                </TabItem>
                <TabItem>
                    <TabItem.Header>
                        <Image Source="https://img.dotnet9.com/logo.png"/>
                    </TabItem.Header>
                    <Grid>
                        <Grid.RowDefinitions>
                            <RowDefinition Height="50"/>
                            <RowDefinition Height="*"/>
                        </Grid.RowDefinitions>
                        <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" FontSize="30">
                            <Hyperlink Click="ShowWeb_Click" Tag="https://dotnet9.com">https://dotnet9.com</Hyperlink>
                        </TextBlock>
                        <WebBrowser Grid.Row="1" Margin="5" Source="https://dotnet9.com"/>
                    </Grid>
                </TabItem>
            </dragablz:TabablzControl>
        </Grid>
    </Grid>
</Window>

后台代码【MainWindow.xaml.cs】实现鼠标左键拖动窗体、右上角关闭窗体、超链接打开网站等功能:

private void Window_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
    DragMove();
}

private void Close_Click(object sender, RoutedEventArgs e)
{
    this.Close();
}

private void ShowWeb_Click(object sender, RoutedEventArgs e)
{
    Process.Start((sender as Hyperlink).Tag.ToString());
}
