创建工作流设计器 [英] Creating a Workflow Designer

问题描述

我在.Net中开发了一个小型工作流引擎，它以xml

配置的形式存储。现在我们没有任何图形设计器，所以我们通过简单的基于网格的配置来实现它。但是现在我想创建一个带有拖动和

drop facilty的工作流设计器，以使最终用户更容易配置它。

但我不知道从哪里开始以及我可以使用的所有东西。如果有人有这方面的知识

请与我分享并解释我如何实现这一点。



在预先感谢

Hi,
I have developed a small Workflow Engine in .Net which gets stored in the form of xml
configuration. Right now we don't have any graphical designer for it so we do it through a
simple grid based configuring. But now I want to create a Workflow Designer with drag and
drop facilty to make it easier and more interative for end user to configure it.
But I have no clue from where to start and what all things I can use. If anyone has knowledge
about this please share it with me and explain me how can I implement this.

Thanks in Advance

推荐答案

几年前我曾经开发过Workflow Designer（加上一些功能关闭的组件，比如2D CAD，绘图等） - 它是Borland Delphi。根据我的经验，我会使用WPF，但是你需要.NET Framework 3.5或4.0。

请看我之前的回答 - 这个问题：如何使用C＃绘制2D线图？ [ ^ ]。在那个答案中，我概述了所涉及的内容。使用v.2.0，您将被绑定到 System.Windows.Forms ，我也会考虑这个。



你也可以尝试找一些可以帮助你的组件库。在这一刻，我不知道我真正喜欢什么，但也许这是因为我记住使用好的模式，所以我会从头开始。与传统的渲染/绘图方法相比，WPF非常强大，更加面向图表。

I used to develop Workflow Designer few years ago (plus some components close in functionality, such as 2D CAD, plotting, etc.) -- it was Borland Delphi. Based on my experience, I would use WPF, but then you need .NET Framework 3.5 or 4.0.
Please see my previous answer -- to this question: How to draw a 2D line plot using C#?[^]. In that answer I overview what's involved. With v.2.0 you're bound to System.Windows.Forms, which I also consider.

You could also try and find some component library which could help you. At this moment I don't know anything I really like, but maybe this is because I keep in mind nice patterns to use, so I would do it from scratch. WPF is really powerful and much more oriented to diagramming compared to traditional rendering/drawing approach.

除了SAKryukov提出的综合解决方案，你可以考虑

重新托管工作流程设计器

[ ^ ]，它可能更容易:)

In addition to the comprehensive solution proposed by SAKryukov, you could consider

[^], it might be easier :)
