1. 本文背景

本文介绍利用第三方开源库 Dragablz 实现可拖拽的 TabControl,本文代码结果图以下:



2. 代码实现

利用 .Net Framework 4.8 建立名为 “TabMenu2” 的WPF模板项目,增加三个Nuget库:MaterialDesignThemes、MaterialDesignColors 和 Dragablz,此中 TabControl 的拖拽服从是由 Dragablz 库实现的。

以下为三个库详细版本:

<?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>

处理计划首要文件目次构造布局:

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

注:站长测验测验利用 .NET CORE 3.1 建立WPF项目,但 Dragablz 库临时未供应 .NET CORE 的版本。想着本身编译 Dragablz 的 .NET CORE 版本,何如功力不敷,改了一些源码,最后放弃了。文中代码及文末给出的 Demo 运行法度需求在 .NET Framework 4.0 运行时环境下运行,想测验测验编译 Dragablz 库的朋友可在文末给出的链接中下载编译。

2.1 引入款式

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 库的款式文件:

<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 库的定名空间,【dragablz:TabablzControl】为 Dragablz 库封装的 TabControl,利用体例和原生控件近似,单项标签仍然利用 TabItem,利用起来很简朴,源码以下:

<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="欢迎拜候Dotnet9的博客:"/>                            <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>                <TabItem Header="设想">                    <Grid>                        <Grid.RowDefinitions>                            <RowDefinition Height="50"/>                            <RowDefinition Height="*"/>                        </Grid.RowDefinitions>                        <TextBlock Text="为用户体验办事!" FontSize="30" HorizontalAlignment="Center" VerticalAlignment="Center"/>                        <WebBrowser Grid.Row="1" Margin="5" Source="https://dotnet9.com"/>                    </Grid>                </TabItem>                <TabItem Header="帮忙">                    <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>

背景代码【MainWindow.xaml.cs】实现鼠标左键拖动窗体、右上角封闭窗体、超链接翻开网站等服从:

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());}
