C#中用Form实现浮动工具栏(转)_

今天才发觉微软XX的在.net 2003里边没给提供浮动工具栏控件，没办法google了一下只找到几个第三方的控件，要付费不过功能倒是挺强悍。考虑一下偶只是需要一个简单的浮动条，不至于用到那些太多的牛x功能，自己动手丰衣足食吧！

    基本思路，用一个无text，ControlBox=false的窗体，设置其top属性为true作为该工具条的载体

    在窗体MouseDown,MouseMove,MouseUp事件中处理工具条的移动

 

代码：

 

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;

namespace SmartBoard
{
 /// <summary>
 /// Form1 

 /// </summary>
 public class NPButton : System.Windows.Forms.Form
 {
  protected SmartBoard ParentFrom = null;
  private int mouseX,mouseY,currX,currY;
  public System.Windows.Forms.Button button3;
  public System.Windows.Forms.Button button2;
  /// <summary>
  ///

  /// </summary>
  private System.ComponentModel.Container components = null;

  public NPButton(SmartBoard parent)
  {
   //
   // Windows

   //
   InitializeComponent();
   this.ParentFrom = parent;
   //
   // TODO: InitializeComponent 

   //
  }

  /// <summary>
  /// 

  /// </summary>
  protected override void Dispose( bool disposing )
  {
   if( disposing )
   {
    if(components != null)
    {
     components.Dispose();
    }
   }
   base.Dispose( disposing );
  }
