继续学习IReaper(3)

在GlobalInit()这个函数里:

private static void GlobalInit()
       {
           LocalAppFolder = System.IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "iReaper");
           Control.CheckForIllegalCrossThreadCalls = false;
           //init browser
           //check for upgrade
           IReaper.CommonGui.ButtonStatuMonitor.Init();
           if (Properties.Settings.Default.CallUpgrade)
           {
               Settings.Default.Upgrade();
               Settings.Default.CallUpgrade = false;
               Settings.Default.Save();
           }
           //create runningCourseFile
           Core.CoreData[CoreDataType.CurrentViewedFiles] = new FileData.RunningCourseFileDataCollection(true);//得先搞清后面这个类
           //ToolStripManager.Renderer = new iReaperToolStripRender();
           IReaper.Utils.SetCulture(Application.CurrentCulture);


       }

Control.CheckForIllegalCrossThreadCalls,比较有用,往往在我们需要在另一个线程调用Windows控件时,避免对编译安全的错误提示.

剩下的:if语句块暂时先放一放.下面来看:new FileData.RunningCourseFileDataCollection这个类:

 

public class RunningCourseFileDataCollection : CourseFileDataCollection
   {
       #region static region

       #endregion

       bool _isHook;
       /// <summary>
       ///
       /// </summary>
       /// <param name="isHook">是否邦定</param>
       public RunningCourseFileDataCollection(bool isHook)
           : base()
       {
           if (!isHook)
           {
               this.RemoveHook();
           }
           this._isHook = isHook;

       }

       /// <summary>
       /// 根据下载运行体状态的变化，将非创建的，结束的数据都加进来
       /// </summary>
       /// <param name="Data"></param>
       [MethodImpl(MethodImplOptions.Synchronized)]
       protected override void CourseFileData_StatueChange(CourseFileData Data)
       {
           int index = -1;
           if (Data.RunState == RunningStatue.Created ||
               Data.RunState == RunningStatue.Finished)
           {
               lock (this)//删除对象需要上锁
               {
                   if (this.Contains(Data))
                   {
                       this.Remove(Data);
                   }
               }
           }
           else if ((index = this.IndexOf(Data)) >= 0)
           {
               this.ResetItem(index);
           }
           else if (Data.RunState == RunningStatue.RunRequest ||
                   Data.RunState == RunningStatue.Running)
           {
               this.Add(Data);
               this.ResetItem(this.Count - 1);
           }
       }
       /// <summary>
       /// <seealso cref="BindingList"/>
       /// </summary>
       /// <param name="Data"></param>
       public new void Add(CourseFileData Data)
       {
           if (this.Contains(Data))
           {
               return;
           }
           base.Add(Data);
       }
   }

 

CourseFileData为 用来存储某个文件所代表的数据，将支持下载初始化、开始下载、暂停、启动、结束、运行完成任务等功能的数据 .

继续学习之前,我想把事件的使用方法在分析一下.

事件本身是代理的实例化(微软提供的例子)

分析后明白事件的声明其实在调用者本身,事件的处理是在另一个类里.能否在同一个类里呢?我觉得也可以

显然这么做没什么意义.实现代理是为了更方便的编写程序.
