WinForm——Button总结

1. 常用属性
2. 实例总结

• 如何动态创建Button控件。

想要动态创建控件，首先要创建控件类的对象，然后使用系统Controls对象的Add方法将控件注册到窗体中。例：

private void Form1_MouseDown(object sender,MouseEventArgs e)

{

       Button btn=new Button();

btn.Left=e.X;

btn.Top=e.Y;

btn.Name=”Button”+intCount.ToString();

btn.Text=”Button:+intCount.ToString();

this.Controls.Add(btn);

intCount++;

}

• 实现对Button按钮的重绘

新建用户控件，命名为ControlButton。然后将继承改为Button

  public partial class ControlButton : Button

    {

        public ControlButton()

        {

            this.SetStyle(

                ControlStyles.UserPaint |

                ControlStyles.AllPaintingInWmPaint |

                ControlStyles.OptimizedDoubleBuffer |

                ControlStyles.ResizeRedraw |

                ControlStyles.SupportsTransparentBackColor, true);

            FlatStyle = FlatStyle.Flat;

            FlatAppearance.BorderSize = 1;

            FlatAppearance.BorderColor = Color.FromArgb(102, 102, 102);

            FlatAppearance.MouseOverBackColor = Color.FromArgb(102, 102, 102);

            FlatAppearance.MouseDownBackColor = Color.FromArgb(150, 150, 150);

        }

        private bool _isClicked = false;

        public bool IsClicked

        {

            get { return _isClicked; }

            set { _isClicked = value; }

        }

        private bool _inClient = false;

        private bool _mouseDown = false;

        private bool _enableClicked = false;

        [Category("自定义属性"), Description("启用按下状态")]

        public bool EnableClicked

        {

            get { return _enableClicked; }

            set { _enableClicked = value; }

        }

        private Color _fontColor = Color.Gainsboro;

        [Category("自定义属性"), Description("按下状态字体颜色")]

        public Color ClickedForeColor

        {

            get { return _fontColor; }

            set { _fontColor = value; }

        }

        private Size _imgSize;

        [Category("自定义属性"), Description("图片尺寸")]

        public Size ImageSize

        {

            get { return _imgSize; }

            set

            {

                _imgSize = value;

                Invalidate();

            }

        }

        private Image _enterImage = null;

        [Category("自定义属性"), Description("鼠标悬浮时图片")]

        public Image EnterImage

        {

            get { return _enterImage; }

            set

            {

                _enterImage = value;

            }

        }

        private Image _downImage = null;

        [Category("自定义属性"), Description("鼠标按下时图片")]

        public Image DownImage

        {

            get { return _downImage; }

            set { _downImage = value; }

        }

        protected override void OnMouseDown(MouseEventArgs mevent)

        {

            IsClicked = !IsClicked;

            _mouseDown = true;

            base.OnMouseDown(mevent);

        }

        protected override void OnMouseUp(MouseEventArgs mevent)

        {

            _mouseDown = false;

            base.OnMouseUp(mevent);

        }

        protected override void OnMouseEnter(EventArgs e)

        {

            _inClient = true;

            base.OnMouseEnter(e);

        }

        protected override void OnMouseLeave(EventArgs e)

        {

            _inClient = false;

            base.OnMouseLeave(e);

        }

}

生成成功后，在工具箱里面就可以看到。
