AY 用wpf写个ide雏形的记录[1/15]

以前我写的一篇avalonDock文章没啥意思,现在又有时间折腾了,以下内容自己做个笔记

====================www.ayjs.net       杨洋    wpfui.com        ayui      ay  aaronyang=======请不要转载谢谢了。=========

总结结构:

DockingManager

LayoutRoot

LayoutPanel

后面的LayoutDocumentPaneGroup可以理解为分组

接着开始就是填内容,有两类

LayoutAnchorablePane,这控件是可以再放到全局任意一个地方

LayoutDocumentPane ,这控件主要是文档内容,一般取中间,反正就是需要足够的位置给它。

重要功能 布局的保存,把布局写到文件,然后在恢复布局。

源码代码量庞大,大致知道就好,

这个库,每一次上一个版本的代码都是开源的,目前开源的是3.4,在github的wpftoolkit里 最新的是3.8

我们直接nuget安装3.8的avalondock和它的theme

IDE基本基于命令去做,命令有作用域,有的快捷键只是某个控件的,有的是全局的,一个命令的定义离不开 RoutedUICommand 知识点

接下来知识点就是 绑定 ,不懂的先回去复习下,本文在最后一篇修改外观,前面的外观丑陋皆可以理解

示例命令:

using System.Windows.Input;

namespace Study_DOCK
{
    public class AppCommand
    {
        private static RoutedUICommand newFile;

        static AppCommand()
        {
            InputGestureCollection inputs = new InputGestureCollection();
            AppCommand.newFile = new RoutedUICommand("新建文件", "NewFile", typeof(AppCommand), inputs);
        }


        public static RoutedUICommand NewFile
        {
            get { return AppCommand.newFile; }
        }

    }
}

static构造函数里面实例它,这是最简单的,不包括快捷键和执行,是否执行的。

using System.Windows.Input;

namespace Study_DOCK
{
    public class AppCommand
    {
       
        static AppCommand()
        {
            InputGestureCollection inputs = new InputGestureCollection();
            AppCommand.newFile = new RoutedUICommand("新建文件", "NewFile", typeof(AppCommand), inputs);

            inputs = new InputGestureCollection();
            AppCommand.loadFile = new RoutedUICommand("打开", "LoadFile", typeof(AppCommand), inputs);

            inputs = new InputGestureCollection();
            AppCommand.pinUnpin = new RoutedUICommand("固定\\取消固定", "PinUnpin", typeof(AppCommand), inputs);

            inputs = new InputGestureCollection();
            AppCommand.addMruEntry = new RoutedUICommand("添加到最近列表", "AddEntry", typeof(AppCommand), inputs);

            inputs = new InputGestureCollection();
            AppCommand.removeMruEntry = new RoutedUICommand("从最近列表移除", "RemoveEntry", typeof(AppCommand), inputs);

            inputs = new InputGestureCollection();
            AppCommand.browseURL = new RoutedUICommand("打开URL", "OpenURL", typeof(AppCommand), inputs);

            inputs = new InputGestureCollection();
            AppCommand.showStartPage = new RoutedUICommand("显示起始页", "ShowStartPage", typeof(AppCommand), inputs);
        }


        private static RoutedUICommand newFile;
        public static RoutedUICommand NewFile
        {
            get { return AppCommand.newFile; }
        }


        private static RoutedUICommand loadFile;
        public static RoutedUICommand LoadFile
        {
            get { return AppCommand.loadFile; }
        }




        private static RoutedUICommand pinUnpin;
        public static RoutedUICommand PinUnpin
        {
            get { return AppCommand.pinUnpin; }
        }


        private static RoutedUICommand addMruEntry;
        public static RoutedUICommand AddMruEntry
        {
            get { return AppCommand.addMruEntry; }
        }


        private static RoutedUICommand removeMruEntry;
        public static RoutedUICommand RemoveMruEntry
        {
            get { return AppCommand.removeMruEntry; }
        }

        private static RoutedUICommand browseURL;
        public static RoutedUICommand BrowseURL
        {
            get { return AppCommand.browseURL; }
        }


        private static RoutedUICommand showStartPage;
        public static RoutedUICommand ShowStartPage
        {
            get { return AppCommand.showStartPage; }
        }
    }
}

接下来View是要对应Bind,也就是你们说的ViewModel,我整理了文件夹

AY 用wpf写个ide雏形的记录[1/15]

一个Bind需要基础的通知父类,如果界面存在command,就需要一个RelayCommand

我找的RelayCommand代码如下:

    public RelayCommand(Action<T> execute, Predicate<T> canExecute)
    {
      if (execute == null)

AY 用wpf写个ide雏形的记录[1/15]

主窗口是唯一的,所以Model静态即可,wpf的静态实例不允许绑定的,你可以这样写

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Study_DOCK
{
    public class MainWindowBind: ViewDataConext
    {
        static MainWindowBind _DataConext = new MainWindowBind();

        public static MainWindowBind DataConext
        {
            get { return _DataConext; }
        }

        public MainWindowBind()
        {

        }
    }
}

一种xaml前台,我们这里偷懒后台,MainWindow.xaml.cs写到

AY 用wpf写个ide雏形的记录[1/15]

ViewBind中写:

        private string _Hello;

        public string Hello
        {
            get { return _Hello; }
            set
            {
                              Set("Hello", ref _Hello, value);
            }
        }

        RelayCommand _GetHello = null;
        public ICommand GetHello
        {
            get
            {
                if (_GetHello == null)
                {
                    _GetHello = new RelayCommand(() =>
                    {
                        MessageBox.Show(Hello);
                    }, 
                    () => { return true; });
                }

                return _GetHello;
            }
        }

关于通知,你可以3种写法

还有种

              if (_Hello == value) return;
                _Hello = value;
                RaisePropertyChanging("Hello");

xaml

知识点:字母前面加_ 下划线,是响应Alt键的,

AY 用wpf写个ide雏形的记录[1/15]

直接使用绑定方式,即时ViewBind中没有该属性不报错。

菜单,可以直接Command,也可以Click,当然动态菜单需求来了,这里我们来写个最近文件列表

我们需要写个转换器,0个文件列表,就不显示该MenuItem

加一个Share文件夹,放入转换器的文件

知识点2:

AY 用wpf写个ide雏形的记录[1/15]

这种写法是单例转换器,不需要前台声明就可以用了。

打开Bind文件,写入一个列表集合,给MenuItem的ItemResource使用

一个文件列表,在menuitem存在,在起始页也存在,有图标,路径,选中,激活等属性,

每个文件都可以打开变成1个单独的documenttab

定义第一期IDE中的一些Model

定义一个Pane,格子Model

一个格子,标题,图标Uri,唯一ContentId,是否选中,是否激活,暂时先定义这么多

namespace Study_DOCK
{
    using System;

    public class PaneDataContext : ViewDataConext
    {
        public PaneDataContext()
        { }


        #region Title

        private string _title = null;
        public string Title
        {
            get { return _title; }
            set
            {
                if (_title != value)
                {
                    _title = value;
                    RaisePropertyChanged("Title");
                }
            }
        }

        #endregion

        public virtual Uri IconSource
        {
            get;

            protected set;
        }

        #region ContentId

        private string _contentId = null;
        public string ContentId
        {
            get { return _contentId; }
            set
            {
                if (_contentId != value)
                {

                    RaisePropertyChanged("ContentId");
                }
            }

        {
            get { return _isSelected; }

                    RaisePropertyChanged("IsSelected");
                }
            }
        }

        #endregion

        #region IsActive

        private bool _isActive = false;
        public bool IsActive
        {
            get { return _isActive; }
            set
            {

                }
            }
        }

        #endregion


    }
}

加入Tool,只是额外的2个属性

namespace Study_DOCK
{
    public class ToolDataContext : PaneDataContext
    {
        public ToolDataContext(string name)
        {
            Name = name;
            Title = name;
        }

        public string Name
        {
            get;
            private set;
        }


        #region IsVisible

        private bool _isVisible = true;
        public bool IsVisible
        {
            get { return _isVisible; }
            set
            {
                if (_isVisible != value)
                {
                    _isVisible = value;
                    RaisePropertyChanged("IsVisible");
                }
            }
        }

        #endregion


    }
}

“最近打开文件”业务:

using System.Windows.Input;

namespace Study_DOCK

    public abstract class FileBaseDataContext : PaneDataContext
    {
   
        private bool mIsFilePathReal = false;

        /// <summary>

            }

            set
            {
                this.mIsFilePathReal = value;
            }
        }

        abstract public string FilePath { get; protected set; }

        abstract public bool IsDirty { get; set; }

        #region CloseCommand

        }

        {
            get;
        }
        #endregion
  
    }
}

IsDirty标记文件是否保存了,未保存,文件名后面,加上*号

然后定义avalondock的tabitem的DataContext

当前文件结构如下:

AY 用wpf写个ide雏形的记录[1/15]

这个时候,可以定义一个文件列表的Item了,给每条MenuItem的绑定环境

特性:列表,顺序,还可以单击操作,文件名太长,前面要省略

这里参考微软的MRU的实现

此时项目结构

AY 用wpf写个ide雏形的记录[1/15]

先模拟一个菜单列表MRUListVM,我们用RecentFilesBind包装下

namespace Study_DOCK
{
    using ay.Control.MRU.Data;
    using System;
    using System.IO;

    public class RecentFilesBind : ToolDataContext
    {
        private MRUListVM mMruList;

        public const string ToolContentId = "RecentFilesTool";

        public RecentFilesBind()
          : base("最近文件列表")
        {
            ContentId = ToolContentId;
            this.mMruList = new MRUListVM();
        }

        public override Uri IconSource
        {
            get
            {
                return new Uri("pack://application:,,,/Study_DOCK;component/Contents/Image/NoPin16.png", UriKind.RelativeOrAbsolute);
            }
        }

        public MRUListVM MruList
        {
            get
            {
                return this.mMruList;
            }

            private set
            {
                if (this.mMruList != value)
                {
                    this.mMruList = value;
                    this.RaisePropertyChanged(() => this.MruList);
                }
            }
        }

        public void AddNewEntryIntoMRU(string filePath)
        {
            if (this.MruList.FindMRUEntry(filePath) == null)
            {
                MRUEntryVM e = new MRUEntryVM() { IsPinned = false, PathFileName = filePath };

                this.MruList.AddMRUEntry(e);

                this.RaisePropertyChanged(() => this.MruList);
            }
        }
    }
}

打开MainWindowBind.cs

 public MainWindowBind()
        {
            this.RecentFiles.MruList.AddMRUEntry(@"E:\AYUI7\AYUI7\WpfApplication1\App,xaml");
            this.RecentFiles.MruList.AddMRUEntry(@"E:\AYUI7\AYUI7\WpfApplication1\App,xaml.cs");
            this.RecentFiles.MruList.AddMRUEntry(@"E:\AYUI7\AYUI7\WpfApplication1\MainWindow.xaml");
            this.RecentFiles.MruList.AddMRUEntry(@"E:\AYUI7\AYUI7\WpfApplication1\MainWindow.xaml.cs");
            this.RecentFiles.MruList.AddMRUEntry(@"E:\AYUI7\AYUI7\WpfApplication1\WpfApplication1.csproj");
        }


        private RecentFilesBind _recentFiles = null;
        public RecentFilesBind RecentFiles
        {
            get
            {
                if (_recentFiles == null)
                    _recentFiles = new RecentFilesBind();

                return _recentFiles;
            }
        }

AY 用wpf写个ide雏形的记录[1/15]

AY 用wpf写个ide雏形的记录[1/15]

也就是说,可以通过 this.RecentFiles.MruList.AddMRUEntry增加新的打开文件了

      <MenuItem ItemsSource="{Binding RecentFiles.MruList.ListOfMRUEntries}" Header="最近打开文件"
                          Visibility="{Binding Path=RecentFiles.MruList.ListOfMRUEntries, Mode=OneWay, Converter={local:ZeroToVisibilityConverter}}">
                        <MenuItem.ItemContainerStyle>
                            <Style TargetType="MenuItem">
                                <Setter Property="Header" Value="{Binding DisplayPathFileName, Mode=OneWay}" />
                                <Setter Property="Command" Value="local:AppCommand.LoadFile" />
                                <Setter Property="CommandParameter" Value="{Binding PathFileName, Mode=OneWay}" />
                            </Style>
                        </MenuItem.ItemContainerStyle>
                    </MenuItem>

灰色不可用,因为命令,CanExecute的问题,实现就好了

路径处理显示逻辑如下:

   int n = 32;
                return (mMRUEntry.PathFileName.Length > n ? mMRUEntry.PathFileName.Substring(0, 3) +
                                                        "... " + mMRUEntry.PathFileName.Substring(mMRUEntry.PathFileName.Length - n)
                                                      : mMRUEntry.PathFileName);

这样动态菜单也完成了,后面执行打开命令,新建保存后命令就可以加入这个几何,保存xml到本地,下次打开恢复

点写到这里,后面我们新建tab,打开tab,
