玩转控件:Fucking ERP之流程图

前言

首先，跟守护在作者公众号和私信作者催更的朋友们道个歉。疫情的原因，公司从年初到现在一直处于996+的高压模式，导致公众号更新频率较低。而且作者每更新一篇原创公众号，既要对自己沉淀知识负责，也要对愿意和作者一起探讨一起学习一起进步的小伙伴儿们负责，防止误人子弟。所以作者的每一篇原创，都是作者在有限时间内仔细推敲后的产物，希望大家可以理解。

Talk is Cheap!

前面分享的几个章节，差不多把实际用到的控件和容器的封装、扩展、重绘都举例到了(后续如果还有其他特例，作者也会更新进来)。今天要分享的依然是“Fucking ERP”系列中比较重要的环节——流程图。

本章的流程图并非工作流，winform在市面上有很多经典的工作流组件比如微软的WWF，还有很多开源自主研发的工作流组件等等，后续作者实际用到的话也会分享出来和大家一起探讨。此处分享的流程图，主要是"标识"的作用，主要用来表示业务数据的流转，具体数据如何流转，都需要各位后台自行处理（说白了，就是从A表查出数据，插入到B表，然后更新A表标识罢了。）

Show me the Code!

首先，界面加载的时候，初始化控件可用性，以及所有模块列表

private void frmWorkFlow_Load(object sender, EventArgs e)
{
    //创建大模块
    CreateModule();
    this.TabPage1.PageVisible = false;
    this.TabPage2.PageVisible = false;
    this.TabPage3.PageVisible = false;

    this.kzxsBtnAddButton.Enabled = false;
    this.kzxsBtnAddLabel.Enabled = false;
    this.kzxsBtnAddLine.Enabled = false;

    this.Btn_SaveButton.Enabled = false;
    this.Btn_SaveLabel.Enabled = false;
    this.Btn_SaveLine.Enabled = false;

为了满足演示效果，本位都用DataTable来模拟数据库操作。初始化模块菜单方法如下：

//创建主目录
public void CreateModule()
{
    //此处拿DataTable来存储数据库的所有菜单节点，此处用销售模块来举例
    DataTable dtSalesOrder = new DataTable();
    dtSalesOrder.Columns.Add("sID", typeof(Guid));
    dtSalesOrder.Columns.Add("sModel", typeof(string));
    dtSalesOrder.Columns.Add("iOrder", typeof(int));
    dtSalesOrder.Rows.Add(new object[] { Guid.NewGuid(), "销售模块", 1 });

    DataRow[] dr = dtSalesOrder.Select("", "iOrder");

    //存在子菜单生产树结构
    if (dr.Length > 0)
    {
        foreach (DataRow row in dr)
        {
            DevExpress.XtraEditors.SimpleButton sb = new DevExpress.XtraEditors.SimpleButton();
            sb.Name = row["sID"].ToString();
            sb.Text = row["sModel"].ToString();
            sb.Tag = row["sModel"].ToString();
            sb.TabIndex = int.Parse(row["iOrder"].ToString());
            sb.Dock = DockStyle.Top;
            sb.Height = 25;
            sb.Click += onBtnClick;
            panelControl1.Controls.Add(sb);

        }
    }
}

模块按钮绑定了点击事件，用于触发当前选择的菜单的流程图（代码逻辑已经添加，时间有限，本文不做处理，如有疑问，可公众号私信作者一起探讨）

private void onBtnClick(object sender, EventArgs e)
  {
      sModel = ((DevExpress.XtraEditors.SimpleButton)sender).Name.ToString().Trim();
      sModelName = ((DevExpress.XtraEditors.SimpleButton)sender).Text.ToString().Trim();
      //根据选择的菜单模块，加载当前菜单的流程图
      CreateFlowMap(((DevExpress.XtraEditors.SimpleButton)sender).Name.ToString().Trim(), ((DevExpress.XtraEditors.SimpleButton)sender).Text.ToString().Trim());
  }

创建流程图部分方法如下（有需要源码可关注作者公众号，私信作者免费获取）：

//创建流程图
public void CreateFlowMap(string sModelID, string sModelName)
{
    //查找是否存在流程图   
    string sFilter = "sModelCode =  '" + sModelID + "'";
    TabControl2.Visible = true;
    Boolean bExists = false;
    //查找模块流程图是否存在
    foreach (DevExpress.XtraTab.XtraTabPage tabPage in TabControl2.TabPages)
    {
        if (tabPage.Name == sModelID)
        {
            tabPage.PageVisible = true;
            TabControl2.SelectedTabPage = tabPage;
            bExists = true;
        }
        else
        {
            tabPage.PageVisible = false;
        }
    }
    //不存在需要增加页面
    if (!bExists)
    {
    .....

You say a JB without pictures ！无图言X，先给大家看看设计图

图片展示解析：

1.左侧栏初始化动作，加载所有系统模块

2.右侧上部分为操作栏，设计按钮处理当前选中的菜单模块，用于加载/新增/删除当前模块的流程图

3.右侧左边部分为绘制工具栏，此处只拿绘制直线(或带箭头的直线),Label（流程注释），按钮来举例子。

4.右侧下部分为绘制工具栏的属性配置，点击保存，呈现绘制结果如图右侧中间部分

5.流程图展示区，用于加载或绘制流程图

（以上因篇幅和时间限制未做详细测试，主要实现功能为主举个例子，作者绘制期间也有遇到不完善的地方，后续有时间在优化）

代码没有太大难度(需要源码研究可关注作者公众号，私信作者免费获取)，主要跟大家分享下绘制流程模块吧。

(带箭头的)直线的绘制

Talk is Cheap,直接上代码：

KzxLine line = new KzxLine();

  bAddLine = true;
  line.Name = "Line";
  line.Tag = "";
  line.lineWidth = int.Parse(this.cmb_LineWidth.Text.ToString());
  string sColor = this.cmb_ColorLine.Text.ToString().Trim();
  switch (sColor)
  {
      case "Black":
          line.LineColor = KzxLine.ColorType.Black;
          break;
      case "Blue":
          line.LineColor = KzxLine.ColorType.Blue;
          break;
      case "Green":
          line.LineColor = KzxLine.ColorType.Green;
          break;
      case "Lime":
          line.LineColor = KzxLine.ColorType.Lime;
          break;
      case "Red":
          line.LineColor = KzxLine.ColorType.Red;
          break;
      case "Yellow":
          line.LineColor = KzxLine.ColorType.Yellow;
          break;
      default:
          line.LineColor = KzxLine.ColorType.Black;
          break;
  }
  line.IsSolid = !this.chk_Solid.Checked;
  switch (this.cmb_ArrowType.Text.ToString().Trim())
  {
      case "Start":
          line.ArrowPosition = KzxLine.ArrowType.Start;
          break;
      case "End":
          line.ArrowPosition = KzxLine.ArrowType.End;
          break;
      case "All":
          line.ArrowPosition = KzxLine.ArrowType.All;
          break;
      case "None":
          line.ArrowPosition = KzxLine.ArrowType.None;
          break;
  }
  if (this.chk_Horizon.Checked)
  {
      line.LineStyle = KzxLine.LineType.Horizontal;
      line.Left = int.Parse(this.edt_LeftLine.Text.ToString());
      line.Top = int.Parse(this.edt_TopLine.Text.ToString());
      line.Width = int.Parse(this.edt_WidthLine.Text.ToString());
      line.Height = int.Parse(this.cmb_LineWidth.Text.ToString()) * 2 + 10;
  }
  else
  {
      line.LineStyle = KzxLine.LineType.Vertical;
      line.Left = int.Parse(this.edt_LeftLine.Text.ToString());
      line.Top = int.Parse(this.edt_TopLine.Text.ToString());
      line.Width = int.Parse(this.cmb_LineWidth.Text.ToString()) * 2 + 10;
      line.Height = int.Parse(this.edt_HeightLine.Text.ToString());
  }
  line.Visible = true;

  line.Click += onClick;
  MoveClass.BarcodeControl(line);
  if (bFirstControl)
  {
      MoveClass.BarcodeCreate();
      bFirstControl = false;
  }
  this.TabControl2.Enabled = true;
  this.TabControl1.SelectedTabPage = TabPage3;
  this.TabPage3.PageVisible = true;

  this.kzxsBtnAddButton.Enabled = true;
  this.kzxsBtnAddLabel.Enabled = true;
  this.kzxsBtnAddLine.Enabled = true;

其中KzxLine是作者封装的用户控件,（如有需要，请关注公众号私信作者，源码免费赠送）部分代码如下：

protected override void OnPaint(PaintEventArgs e)
{
    base.OnPaint(e);
    //e.Graphics.DrawLine(new Pen(lineColor, lineHeight), 1, 1, this.Width, lineHeight);

    AdjustableArrowCap lineCap = new AdjustableArrowCap(5, 5, true);
    Pen p = new Pen(lineColor, 1);

    string sColor = "";
    if ((int)color == 0) 
    {
        sColor = "Black";
    }
    if ((int)color == 1)
    {
        sColor = "Red";
    }
    if ((int)color == 2)
    {
        sColor = "Yellow";
    }
    if ((int)color == 3)
    {
        sColor = "Blue";
    }
    if ((int)color == 4)
    {
        sColor = "Green";
    }
    if ((int)color == 5)
    {
        sColor = "Lime";
    }
   
    p.Color = Color.FromName(sColor);
    p.Width = LWidth;

    if ((int)ArrowP == 1)
    {
        p.CustomStartCap = lineCap;
    }
    else
        if ((int)ArrowP == 2)
        {
            p.CustomEndCap = lineCap;
        }
        else
            if ((int)ArrowP == 3)
            {
                p.CustomStartCap = lineCap;
                p.CustomEndCap = lineCap;
            }

    if (!Solid)
    {
        float[] dashValues = { 5, 2, 5, 2 };
        p.DashPattern = dashValues;
    }

    int iLeft = 1;
    int iTop = 1;
    int iWidth = 1;
    int iHeight = 1;

    if ((int)sTyle == 0)
    {
        iLeft = 1;
        iTop = LWidth * 2 + 5;
        iWidth = this.Width;
        iHeight = LWidth * 2 + 5;
    }
    else
    {
        iLeft = LWidth * 2 + 5;
        iTop = 1;
        iWidth = LWidth * 2 + 5;
        iHeight = this.Height;
    }
    e.Graphics.DrawLine(p, iLeft, iTop, iWidth, iHeight);
    p.Dispose();
}

点击如图"箭头/直线"按钮后，下面会显示控件的属性配置区域，设置好后点击保存，就会把绘制好的控件添加到流程图展示区。保存事件如下：

private void Btn_SaveLine_Click(object sender, EventArgs e)

        string sColor = this.cmb_ColorLine.Text.ToString().Trim();
        switch (sColor)
        {
            case "Black":

            case "Blue":

        }
    }
}

因所有绘制控件都绑定了拖拽事件，所以可以在流程图展示区随意拖拽部署显示控件（效果见下图）。

Label(注释)控件封装

/// <summary>
    /// 标签验证
    /// </summary>
    public partial class KzxLabel : KzxBaseControl

Label无需重绘只需封装，初始化绑定多语言即可。

public void LayoutControl()
  {
      BindingEvent(this, PluginInfoTable);
      if (this.DesignMode == true)
      {
          this.DesigeCaption = GetLanguage(this.MessageCode, this.DesigeCaption);
      }
  }

  /// <summary>
  /// 绑定事件
  /// </summary>
  /// <param name="eventInfoTable">事件信息表</param>
  public override void BindingEvent(DataTable eventInfoTable)
  {
      BindingEvent(this, eventInfoTable);
  }

  private void KzxLabel_Load(object sender, EventArgs e)
  {
      LayoutControl();
      //UpdateDelegate d = LayoutControl;
      //this.BeginInvoke(d);
  }

按钮控件封装

按钮的封装同上Label一样，具体请移步《玩转控件:扩展Dev中SimpleButton》.或者直接用Dev原生的SimpleButton亦可，此处不做过多废话。只需在属性配置区域的保存事件中，添加到流程图展示区即可，配置区的按钮保存代码如下：

BillInfo info = new BillInfo();
//info.sID = Edt_FrmBtn.EditValue.ToString();
info.sFrmName = Edt_FrmBtn.Text.ToString();
info.sFrmCaption = Edt_CaptionBtn.Text.Trim();
info.sMsgID = Edt_MsgBtn.Text.ToString().Trim();

if (bAddBtn)
{
    DevExpress.XtraEditors.SimpleButton sb = new DevExpress.XtraEditors.SimpleButton();
    sb.Left = int.Parse(Edt_LeftBtn.Text.Trim());
    sb.Top = int.Parse(Edt_TopBtn.Text.Trim());
    sb.Width = int.Parse(Edt_WidthBtn.Text.Trim());
    sb.Height = int.Parse(Edt_HightBtn.Text.Trim());
    sb.Name = Edt_FrmBtn.Text.Trim();
    sb.Text = Edt_CaptionBtn.Text.Trim();

    sb.Tag = info;

    sb.Image = picture1.Image;
    sb.ImageLocation = DevExpress.XtraEditors.ImageLocation.TopCenter;
    sb.Cursor = Cursors.Hand;
    sb.Visible = true;
    TabControl2.SelectedTabPage.Controls.Add(sb);

    sb.Click += onClick;
    MoveClass.BarcodeControl(sb);
    if (bFirstControl)
    {
        MoveClass.BarcodeCreate();
        bFirstControl = false;
    }
    this.TabControl2.Enabled = true;
    bAddBtn = false;

    this.kzxsBtnAddButton.Enabled = true;
    this.kzxsBtnAddLabel.Enabled = true;
    this.kzxsBtnAddLine.Enabled = true;
}
else if ((selectControl is DevExpress.XtraEditors.SimpleButton) && (DevExpress.XtraEditors.SimpleButton)selectControl != null)
{
    ((DevExpress.XtraEditors.SimpleButton)selectControl).Left = int.Parse(Edt_LeftBtn.Text.Trim());
    ((DevExpress.XtraEditors.SimpleButton)selectControl).Top = int.Parse(Edt_TopBtn.Text.Trim());
    ((DevExpress.XtraEditors.SimpleButton)selectControl).Width = int.Parse(Edt_WidthBtn.Text.Trim());
    ((DevExpress.XtraEditors.SimpleButton)selectControl).Height = int.Parse(Edt_HightBtn.Text.Trim());
    ((DevExpress.XtraEditors.SimpleButton)selectControl).Name = Edt_FrmBtn.Text.Trim();
    ((DevExpress.XtraEditors.SimpleButton)selectControl).Text = Edt_CaptionBtn.Text.Trim();

    ((DevExpress.XtraEditors.SimpleButton)selectControl).Tag = info;
    ((DevExpress.XtraEditors.SimpleButton)selectControl).Image = picture1.Image;
    ((DevExpress.XtraEditors.SimpleButton)selectControl).ImageLocation = DevExpress.XtraEditors.ImageLocation.TopCenter;
    ((DevExpress.XtraEditors.SimpleButton)selectControl).Cursor = Cursors.Hand;
}

以上便是"箭头/直线","Label注释","按钮"等功能的准备工作，具体效果如图：

再次强调，因时间和篇幅问题，作者没有对代码做严格的校验，主要以实现功能为主。所以当您拿到源码时需要根据实际情况自行完善，或者后续作者有时间也会继续完善（工作996+的我太难了！）

各个模块功能实现后，就是保存当前绘制的流程图环节了，为了演示效果，作者没有处理数据库相关的工作，主要以DataTable来存储相关绘制数据的。至于图片，作者是用流的方式来存储的，展示时解析即可。

#region 图片处理
  /// <summary>
  /// 点击上传图片
  /// </summary>
  /// <param name="sender"></param>
  /// <param name="e"></param>
  private void picture1_Click(object sender, EventArgs e)
  {
      if (this.openDialog1.ShowDialog() == DialogResult.OK)
      {
          picture1.Image = Image.FromFile(this.openDialog1.FileName);
      }
  }
  /// <summary>
  /// 用流的方式来存储图片
  /// </summary>
  /// <param name="img"></param>
  /// <returns></returns>
  private byte[] convertByte(Image img)
  {
      MemoryStream ms = new MemoryStream();
      img.Save(ms, img.RawFormat);
      byte[] bytes = ms.ToArray();
      ms.Close();
      return bytes;
  }
  private Image convertImg(byte[] datas)
  {
      MemoryStream ms = new MemoryStream(datas);
      Image img = Image.FromStream(ms, true);
      ms.Close();
      return img;
  }

DataTable数据存储如下图：

大家可以根据自己实际情况，存储到数据库或者配置文件中，具体保存代码如下：
