       本节开始我们一起来讨论一些简单的系统控件的实现,在这里我列出一些基本的控件 如下图所示,在写文章的同时我会不断的更新控件,和添加新的控件,也都会一一的发上来和大家分享。

   

    Button控件 是一个很常见也是用的比较多的一个控件,其实他的实现正和他的使用一样的简单明了。

在看它的实现 之前我们先来看看CommandButton用户控件的实现吧

    界面

           

  呵呵 主要看代码吧,这上面没有什么东东可看的

我们先来指定一下默认的事件吧

 

[DefaultEvent("Click")]

 

 

其实这个简单只要这么一行就OK了,但记着一定要写在类的上面哦

 

代码

        
private Image _mouseMoveImage = null;
        
private Image _mouseDownImage = null;
        
private Image _normalImage = null;
        
private ToolTip toolTip;
        
private System.ComponentModel.IContainer components;
        
private string _toolTip;
        
private Color imageTransparentColor;

        
private void InitializeComponent()
        {
            
this.components = new System.ComponentModel.Container();
            
this.toolTip = new System.Windows.Forms.ToolTip(this.components);
            
this.SuspendLayout();
            
// 
            
// CommandButton
            
// 
            this.Name = "CommandButton";
            
this.Size = new System.Drawing.Size(15045);
            
this.ResumeLayout(false);

        }

        
public CommandButton()
        {
            
//this.SetStyle(ControlStyles.DoubleBuffer | ControlStyles.AllPaintingInWmPaint, true);
            this.SetStyle(ControlStyles.UserPaint, true);
            
this.SetStyle(ControlStyles.AllPaintingInWmPaint, true);
            
this.SetStyle(ControlStyles.DoubleBuffer, true);
            
this.SetStyle(ControlStyles.ResizeRedraw, true);
            
this.SetStyle(ControlStyles.SupportsTransparentBackColor, true);
            InitializeComponent();
        }

        
public Image MouseMoveImage
        {
            
get 
            { 
               
                
return _mouseMoveImage;
            }
            
set
            {
                _mouseMoveImage 
= value;
            }
        }

        
public Image MouseDownImage
        {
            
get 
            { 
               
                
return _mouseDownImage;
            }
            
set
            {
                _mouseDownImage 
= value;
            }
        }

        
public Image NormalImage
        {
            
get 
            {
              
                
return _normalImage;
            }
            
set
            {
                _normalImage 
= value;
                
this.BackgroundImage = _normalImage;
            }
        }

        
public Color ImageTransparentColor
        {
            
get
            {
                
return this.imageTransparentColor;
            }
            
set
            {
                
this.imageTransparentColor = value;

                Bitmap image 
= this.BackgroundImage as Bitmap;

                
if (((image != null&& (value != Color.Empty)) && !ImageAnimator.CanAnimate(image))
                {
                    
try
                    {
                        image.MakeTransparent(
this.imageTransparentColor);
                    }
                    
catch
                    { }
                }
            }
        }

        
//重写一下创建控件的方法
        protected override void OnCreateControl()
        {
            
base.OnCreateControl();
            
if (this.NormalImage != null)
            {
                
this.BackgroundImage = NormalImage;
            }
        }

        
//重写进入事件
        protected override void OnMouseEnter(EventArgs e)
        {
            
base.OnMouseEnter(e);

            
if (this.MouseMoveImage != null)
            {
                
this.BackgroundImage = MouseMoveImage;
            }
            
this.Invalidate();
        }

        
//重写离开可见部分的事件
        protected override void OnMouseLeave(EventArgs e)
        {
            
base.OnMouseLeave(e);

            
if (this.NormalImage != null)
            {
                
this.BackgroundImage = NormalImage;
            }
            
this.Invalidate();
        }

        
//重写鼠标按下事件
        protected override void OnMouseDown(System.Windows.Forms.MouseEventArgs e)
        {
            
base.OnMouseDown(e);

            
if (this.MouseDownImage != null)
            {
                
this.BackgroundImage = this.MouseDownImage;
            }
        }

        
//重写鼠标离开事件
        protected override void OnMouseUp(System.Windows.Forms.MouseEventArgs e)
        {
            
base.OnMouseUp(e);

            
if (this.NormalImage != null)
            {
                
this.BackgroundImage = NormalImage;
            }
        }

        
//重写背景修改时的事件
        protected override void OnBackgroundImageChanged(EventArgs e)
        {
            
base.OnBackgroundImageChanged(e);

            
this.ImageTransparentColor = Color.FromArgb(2550255);
        }

        
public string ToolTip
        {
            
get { return _toolTip; }
            
set
            {
                _toolTip 
= value;
                
this.toolTip.SetToolTip(this, _toolTip);
            }
        }
    }

 

在这里我就不多说了,因为代码都很简单,所以很容易看明白,大家看看代码吧。

我们主要来看看Button的控件吧

不用说要先继承一下刚说的用户控件哦

 

 public class Button : CommandButton

 

接下来来看一下 InitializeComponent()方法

代码
  private void InitializeComponent()
        {
            
this.lblText = new Label();
            
this.SuspendLayout();
            
// 
            
// lblText
            
// 
            this.lblText.BackColor = System.Drawing.Color.Transparent;
            
this.lblText.Dock = System.Windows.Forms.DockStyle.Fill;
            
this.lblText.Font = new System.Drawing.Font("宋体"10.5F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(134)));
            
this.lblText.Location = new System.Drawing.Point(00);
            
this.lblText.Name = "lblText";
            
this.lblText.Size = new System.Drawing.Size(7830);
            
this.lblText.TabIndex = 0;
            
this.lblText.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;
            
this.lblText.TextChanged += new System.EventHandler(this.lblText_TextChanged);
            
this.lblText.MouseLeave += new System.EventHandler(this.lblText_MouseLeave);
            
this.lblText.Click += new System.EventHandler(this.lblText_Click);
            
this.lblText.MouseUp += new System.Windows.Forms.MouseEventHandler(this.lblText_MouseUp);
            
this.lblText.MouseEnter += new System.EventHandler(this.lblText_MouseEnter);
            
this.lblText.ForeColor = Shared.FontColor;
            
// 
            
// Button
            
// 
            this.BackgroundImageLayout = System.Windows.Forms.ImageLayout.Stretch;
            
this.Controls.Add(this.lblText);
            
this.Name = "Button";
            
this.Size = new System.Drawing.Size(7830);
            
this.ResumeLayout(false);

        }

 

 

我们让字体同比率的话可以加上这个

 


        
//字体大小
        
//protected override void OnResize(EventArgs e)
        
//{
        
//    base.OnResize(e);
        
//    this.Height = this.Width * 30 / 78;
        
//}

 

当然也要处理一下OnSizeChanged(EventArgs e)事件

 

代码
 //固定比率暂时不需要,如果有需要的话可以取消注释
        
//protected override void OnSizeChanged(EventArgs e)
        
//{
        
//    base.OnSizeChanged(e);

        
//    int Rgn = 0, height = 0, width = 0,rgn=0;

        
//    height = Height > 40 ? Height - 1 : Height;
        
//    width = Width > 110 ? Width - 1 : Width;
        
//    rgn = Height > 40 ? 8 : 7;

        
//    Rgn = Win32.CreateRoundRectRgn(1, 1, width, height, rgn, rgn);

        
//    Win32.SetWindowRgn(this.Handle, Rgn, true);
        
//}
