A simple ArcMap Plug-progress message informs the implementation of the window.
A progress window
① engage in a label, into a gif action figure, so that the form has been transferred Show came out ah ah turn;
② to write out a label prompt text "Please wait" Han; and then engage in a label to display the progress.
Progress Form code is as follows:
A progress window manager
ProgressFormManger
code show as below:
Progress message passing mechanism
A delegate
public delegate void ProgressChangedEventHandler(object o,ProgressChangedEventArgs e);
An interface + event
public interface IProgress
{
event ProgressChangedEventHandler ProgressChangedEvent;
}
A progress message structure
/// <summary>
/// 进度消息结构体。
/// </summary>
public struct ProgressChangedEventArgs
{
/// <summary>
/// 当前处理进度
/// </summary>
public int CurrentIndex { get; set; }
/// <summary>
/// 总的要素个数
/// </summary>
public int FeatureCount { get; set; }
/// <summary>
/// 文字描述的进度消息
/// </summary>
public string Message { get; set; }
}
一个进度消息发送器
消息通知的发起
工作类继承IProgress接口，实现ProgressChangedEvent事件属性
工作类继承ProgressMessagesSender类，实现OnProgressChange方法。
OnProgressChange(checkProgressChangedEventHandler,index, featureCount);
OnProgressChange(this.progressChangeEventHandler, ">>> 创建待处理要素类的副本。");
进度窗口的更新
定义IProgressSetter接口、扩展方法
工具窗口继承IProgressSetter接口
通过GetArcMapRECT方法获取ArcMap窗口四角坐标的结构体，用以实例化进度窗口时确定其位置。
ShowProgressForm方法传入继承IProgress接口的“处理器”，进度消息窗口实例progressForm，进度消息窗口管理器实例manger，展示进度窗体。
