自己建wpf项目，nuget引用安装
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
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：

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
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
<Window x:Class="Study_DOCK.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<TextBox Text="{Binding Hello,UpdateSourceTrigger=PropertyChanged,Mode=TwoWay}"></TextBox>
<Button Command="{Binding GetHello}" Content="获得" Grid.Row="1"></Button>
</Grid>

效果如下
这样一个基本工作就组成了。

知识点：字母前面加_ 下划线，是响应Alt键的，
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：
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)
{
_contentId = value;
RaisePropertyChanged("ContentId");
}
}
}
#endregion
#region IsSelected
private bool _isSelected = false;
public bool IsSelected
{

set
{

{
_isSelected = value;
RaisePropertyChanged("IsSelected");
}
}
}
#endregion
#region IsActive

{
get { return _isActive; }
set
{
if (_isActive != value)
{
_isActive = value;
RaisePropertyChanged("IsActive");
}
}
}
#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
{

此时项目结构
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;
}
}
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，
