玩转控件:重写/重绘Dev中MessageBox弹窗控件

时间：2025-03-07 19:35:38

　　很久没有更新博客了，本想着直接发一篇《手撕ERP》系列，从控件重写、重绘，到框架搭建，再到部分模块实现+业务的。但是每次动手的时候，都觉得难以下手。直接从数据库设计开始吧，模块设计还没定下来，从模块设计开始吧，winform自带控件和DevExpress控件用起来布局实在太难看了。算了，从低做起吧。接着6-7年前的玩转控件系列开始，工欲善其事必先利其器！利器备好，框架搭建完毕，模块设计就是拖控件而已！

Talk is Cheap,Show me the Code!

首先，项目中新建一个窗体（用于后面的弹窗载体），按自己意愿做好布局效果，当然关于皮肤方面，大家可以应用界内很成熟的皮肤控件（具体就不列举了，避免打广告的嫌疑），或者后期自己代码实现。本篇主要介绍如何重写/重绘控件，磨自己的利器，至于利器上贴个动漫图片还是其他花里胡哨的图案，请根据自己的喜好来。大概效果如图（有洁癖的请自己细心布局）：

玩转控件:重写/重绘Dev中MessageBox弹窗控件

　　窗体后台代码分析如下：
        首先窗体集成DevExpress：

 public partial class frm_MessageBox : DevExpress.XtraEditors.XtraForm

　　其余初始化动作代码如下，备注很详细就不一一列举了：

/// <summary>

/// 确定按钮

/// </summary>

private SimpleButton btn_OK;

/// <summary>

/// 取消按钮

/// </summary>

private SimpleButton btn_Cancel;

/// <summary>

/// 中止按钮

/// </summary>

private SimpleButton btn_Abort;

/// <summary>

/// 重试按钮

/// </summary>

private SimpleButton btn_Retry;

/// <summary>

/// 忽略按钮

/// </summary>

private SimpleButton btn_Ignore;

/// <summary>

/// 是按钮

/// </summary>

private SimpleButton btn_Yes;

/// <summary>

/// 否按钮

/// </summary>

private SimpleButton btn_No;

/// <summary>

/// 要在消息框中显示的文本

/// </summary>

private string text;

/// <summary>

/// 要在消息框的标题栏中显示的文本

/// </summary>

private string caption;

/// <summary>

///  System.Windows.Forms.MessageBoxButtons 值之一，可指定在消息框中显示哪些按钮

/// </summary>

private MessageBoxButtons buttons;

/// <summary>

/// </summary>

private MessageBoxIcon icon;

/// <summary>

/// </summary>

private MessageBoxDefaultButton defaultButton;

/// <summary>

/// 消息弹出框参数实体

/// </summary>

MessageBoxModel _MessageBoxModel = default(MessageBoxModel);

界面初始化：

/// <summary>

/// 支持修改弹出框的按钮标题描述

/// </summary>

/// <param name="pMessageBoxModel"></param>

public frm_MessageBox(MessageBoxModel pMessageBoxModel)

{

    InitializeComponent();

    if (pMessageBoxModel == null)

        pMessageBoxModel = new MessageBoxModel();

    this.ControlBox = false;

    this.text = pMessageBoxModel.MsgText;

    this.Text = pMessageBoxModel.FormText ?? "Stephen's UserControl";

    this.caption = pMessageBoxModel.FormText;

    this.buttons = pMessageBoxModel.MsgButton;

    this.icon = pMessageBoxModel.MsgIcon;

    this.defaultButton = pMessageBoxModel.MsgxDefaultButton;

    this._MessageBoxModel = pMessageBoxModel;

}

/// <summary>

    if (moreHeight > )

    {

        this.Height += moreHeight;

    }

  }

　　 代码比较简单，就是把初始化按钮事件和把初始化的弹窗中的按钮添加到布局中的Panel容器里面和一些细节调整，关于方法sysClass.ssLoadMsgOrDefault目前可以不用在意，是我的通用类库，主要是用来实现国际化的，后续会断断续续为大家介绍这块代码。
        按钮绑定事件和键盘响应事件代码如下：

private void PaintIcon(Icon icon, int x, int y)

  {

      Graphics g = this.CreateGraphics();

      g.DrawIcon(icon, x, y);

  }

  void btn_No_Click(object sender, EventArgs e)

  {

      this.DialogResult = DialogResult.No;

  }

  void btn_Yes_Click(object sender, EventArgs e)

  {

      this.DialogResult = DialogResult.Yes;

  }

  void btn_Ignore_Click(object sender, EventArgs e)

  {

      this.DialogResult = DialogResult.Ignore;

  }

  void btn_Retry_Click(object sender, EventArgs e)

  {

      this.DialogResult = DialogResult.Retry;

  }

  void btn_Abort_Click(object sender, EventArgs e)

  {

      this.DialogResult = DialogResult.Abort;

  }

  void btn_Cancel_Click(object sender, EventArgs e)

  {

      this.DialogResult = DialogResult.Cancel;

  }

  void btn_OK_Click(object sender, EventArgs e)

  {

      this.DialogResult = DialogResult.OK;

  }

  private void frm_MessageBox_KeyUp(object sender, KeyEventArgs e)

  {

      if (e.Modifiers == Keys.None)

      {

          if (e.KeyCode == Keys.O && btn_OK != null)

          {

              btn_OK_Click(null, null);

          }

          if (e.KeyCode == Keys.C && btn_Cancel != null)

          {

              btn_Cancel_Click(null, null);

          }

          if (e.KeyCode == Keys.A && btn_Abort != null)

          {

              btn_Abort_Click(null, null);

          }

          if (e.KeyCode == Keys.R && btn_Retry != null)

          {

              btn_Retry_Click(null, null);

          }

          if (e.KeyCode == Keys.I && btn_Ignore != null)

          {

              btn_Ignore_Click(null, null);

          }

          if (e.KeyCode == Keys.Y && btn_Yes != null)

          {

              btn_Yes_Click(null, null);

          }

          if (e.KeyCode == Keys.N && btn_No != null)

          {

              btn_No_Click(null, null);

          }

      }

      if (e.Modifiers == Keys.Control && e.KeyCode == Keys.C)

      {

          string mCopyText = "-------------------------------";

          mCopyText += "\n";

          mCopyText += lblMsg.Text + "\n";

          mCopyText += "-------------------------------";

          Clipboard.SetText(mCopyText);

      }

  }

  private void frm_MessageBox_Paint(object sender, PaintEventArgs e)

  {

      Icon msgIcon;

      switch (icon)

      {

          case MessageBoxIcon.Error:

              msgIcon = System.Drawing.SystemIcons.Error;

              break;

          case MessageBoxIcon.Question:

              msgIcon = System.Drawing.SystemIcons.Question;

              break;

          case MessageBoxIcon.Exclamation:

              msgIcon = System.Drawing.SystemIcons.Exclamation;

              break;

          default:

              msgIcon = System.Drawing.SystemIcons.Information;

              break;

      }

      e.Graphics.DrawIcon(msgIcon, , );

  }

}

以及弹窗实体类：

/// <summary>

/// 弹出框实体

/// </summary>

public class MessageBoxModel

{

    /// <summary>

    /// 弹出框标题

    /// </summary>

    public string FormText { get; set; }

    /// <summary>

    /// 弹出框宽度

    /// </summary>

    public int FormWidth { get; set; }

    /// <summary>

    /// 弹出框高度

    /// </summary>

    public int FormHeight { get; set; }

    /// <summary>

    /// 弹出框消息内容

    /// </summary>

    public string MsgText { get; set; }

    /// <summary>

    /// 文字大小

    /// </summary>

    public int FontSize { get; set; }

    /// <summary>

    /// “是”按钮标题

    /// </summary>

    public string YesButtonText { get; set; }

    /// <summary>

    /// “否”按钮标题

    /// </summary>

    public string NoButtonText { get; set; }

    /// <summary>

    /// “取消”按钮标题

    /// </summary>

    public string CancleButtonText { get; set; }

    /// <summary>

    /// 弹出框类型（提示型、选择型等）

    /// </summary>

    public MessageBoxButtons MsgButton = MessageBoxButtons.OK;

    /// <summary>

    /// 弹出框中显示的图标

    /// </summary>

    public MessageBoxIcon MsgIcon = MessageBoxIcon.Information;

    /// <summary>

    /// 弹出框默认选中的按钮

    /// </summary>

    public MessageBoxDefaultButton MsgxDefaultButton = MessageBoxDefaultButton.Button1;

细心的读者会发现，博主在实例弹窗实体的时候，有个语法糖：

 /// <summary>

    /// 消息弹出框参数实体

    /// </summary>

    MessageBoxModel _MessageBoxModel = default(MessageBoxModel);

default(T) 这是C# 7.1的关键字新用法，主要用法是默认值表达式，default对应各种类型生成默认值列表如下：

玩转控件:重写/重绘Dev中MessageBox弹窗控件

　　罗列一下上述列表中常见类型对应的值

default(string) // null

default(int) //

default(int?) // null

default(dynamic) // null

default(DateTime) // 0001/01/01 0:00:00

default(DateTime?) // null

　篇幅有限，具体深入了解请大家自行百度看看微软文档的解释。
     以上是窗体代码解析，窗体创建好了，最后一步，创建一个实体类(暂时命名KzxMessageBox)用来调用弹窗的窗体显示，具体代码如下：

public class KzxMessageBox

{

    /// <summary>

    /// 标题

    /// </summary>

    private static string caption;

    /// <summary>

    /// 按钮(默认“OK”)

    /// </summary>

    private static MessageBoxButtons buttons;

    /// <summary>

    /// 图标(默认“information”)

    /// </summary>

    private static MessageBoxIcon icon;

    /// <summary>

    /// 默认按钮（默认“button1”）

    /// </summary>

    private static MessageBoxDefaultButton defaultButton;

    /// <summary>

    /// 静态构造函数，初始化数据

    /// </summary>

    static KzxMessageBox()

    {

        if (SysVar.loginType == )

        {

            caption = "Stephen's UserControl";

        }

        else

        {

            caption = sysClass.ssLoadMsgOrDefault("SYS000008", "Stephen's UserControl");

        }

        buttons = MessageBoxButtons.OK;

        icon = MessageBoxIcon.Information;

        defaultButton = MessageBoxDefaultButton.Button1;

    }

    /// <summary>

    /// 显示具有指定文本、标题、按钮、图标和默认按钮的消息框

    /// </summary>

    /// <param name="text">文本</param>

    /// <returns></returns>

    public static DialogResult Show(string text)

    {

        return Show(text, buttons, icon, defaultButton, null);

    }

    /// <summary>

    /// </summary>

    /// <param name="text">文本</param>

    /// <returns></returns>

    public static DialogResult Show(string text, int pFormWidth = , int pFormHeight = )

    {

        return Show(text, buttons, icon, defaultButton, null, pFormWidth, pFormHeight);

    }

    /// <summary>

    public static DialogResult Show(string text, Form parent)

    {

        return Show(text, buttons, icon, defaultButton, parent);

    }

    /// <summary>

    /// </summary>

    /// <param name="text">文本</param>

    /// <param name="buttons">按钮</param>

    /// <returns></returns>

    public static DialogResult Show(string text, MessageBoxButtons buttons)

    {

        return Show(text, buttons, icon, defaultButton, null);

    }

    /// <summary>

    public static DialogResult Show(string text, MessageBoxButtons buttons, Form parent)

    {

    public static DialogResult Show(string text, MessageBoxButtons buttons, MessageBoxIcon icon)

    {

        return Show(text, buttons, icon, defaultButton, null);

    }

    /// <summary>

    public static DialogResult Show(string text, MessageBoxButtons buttons, MessageBoxIcon icon, Form parent)

    {

    }

    /// <summary>

    public static DialogResult Show(string text, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton)

    {

        return Show(text, buttons, icon, defaultButton, null);

    }

    /// <summary>

    /// 显示具有指定文本、标题、按钮、图标和默认按钮的消息框

    /// </summary>

    /// <returns>System.Windows.Forms.DialogResult 值之一</returns>

    public static DialogResult Show(string text, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton, Form parent, int pFormWidth = , int pFormHeight = )

    {

        using (frm_MessageBox frm = new frm_MessageBox(text, caption, buttons, icon, defaultButton))

        {

            if (parent == null || parent.IsDisposed)

            {

                frm.StartPosition = FormStartPosition.CenterScreen;

                if (pFormWidth != ) frm.Width = pFormWidth;

                if (pFormHeight != ) frm.Height = pFormHeight;

                return frm.ShowDialog();

            }

            else

            {

                frm.StartPosition = FormStartPosition.CenterParent;

                if (pFormWidth != ) frm.Width = pFormWidth;

                if (pFormHeight != ) frm.Height = pFormHeight;

                return frm.ShowDialog(parent);

            }

        }

    }

    public static DialogResult Show(Form parent, MessageBoxModel pMessageBoxModel)

    {

        using (frm_MessageBox frm = new frm_MessageBox(pMessageBoxModel))

        {

            if (parent == null || parent.IsDisposed)

            {

                frm.StartPosition = FormStartPosition.CenterScreen;

                if (pMessageBoxModel.FormWidth != ) frm.Width = pMessageBoxModel.FormWidth;

                if (pMessageBoxModel.FormHeight != ) frm.Height = pMessageBoxModel.FormHeight;

                return frm.ShowDialog();

            }

            else

            {

                frm.StartPosition = FormStartPosition.CenterParent;

                if (pMessageBoxModel.FormWidth != ) frm.Width = pMessageBoxModel.FormWidth;

                if (pMessageBoxModel.FormHeight != ) frm.Height = pMessageBoxModel.FormHeight;

                return frm.ShowDialog(parent);

            }

        }

    }

}

　　代码比较简单，创建一个公共类，以及类型Messagebox的方法重载而已！
        最后一步，调用：

private void button1_Click(object sender, EventArgs e)

  {

      KzxMessageBox.Show("this is a test!");

      KzxMessageBox.Show("This is a test!", MessageBoxButtons.OKCancel, MessageBoxIcon.Question, MessageBoxDefaultButton.Button1);

  }

　　一起看下效果：
