winfrom 重绘checkbox 使前面的选着框变大

[大_爱]

请问这个怎么做啊。

我在网上下了一份示例性的代码

public class SkinCheckBox:CheckBox
	{
		private State state=State.Normal;

		public SkinCheckBox()
		{
			this.SetStyle(ControlStyles.SupportsTransparentBackColor, true);
			this.BackColor = System.Drawing.Color.Transparent;
		}

		protected override void OnMouseEnter(EventArgs e)
		{
			state = State.MouseOver;
			this.Invalidate();
			base.OnMouseEnter(e);
		}

		protected override void OnMouseLeave(EventArgs e)
		{
			state = State.Normal;
			this.Invalidate();
			base.OnMouseLeave(e);
		}

		protected override void OnMouseDown(System.Windows.Forms.MouseEventArgs e)
		{
			if ((e.Button & MouseButtons.Left) != MouseButtons.Left) return;

			state = State.MouseDown;
			this.Invalidate();
			base.OnMouseDown(e);
		}

		protected override void OnMouseUp(System.Windows.Forms.MouseEventArgs e)
		{
			if ((e.Button & MouseButtons.Left) == MouseButtons.Left)
				state = State.Normal;
			this.Invalidate();
			base.OnMouseUp(e);
		}
		
		protected override void OnPaint(System.Windows.Forms.PaintEventArgs e)
		{	
			if (SkinImage.checkbox.img==null) 
			{
				base.OnPaint(e);
				return;
			}

			int i = (int)state;
			if (!this.Enabled) i = 16;
			if (this.CheckState == CheckState.Checked) i+=16;
			if (this.CheckState == CheckState.Indeterminate) i+=16;

			Rectangle rc = this.ClientRectangle;
			Rectangle r1 = rc;;
			Graphics g = e.Graphics;
			base.OnPaint(e);
			
			int cw = SystemInformation.MenuCheckSize.Width ;

			if (this.CheckAlign == ContentAlignment.MiddleLeft)
			{
				r1=Rectangle.FromLTRB(0,(r1.Height-cw)/2,0+cw,(r1.Height+cw)/2);
			} 
			else
			{
				r1=Rectangle.FromLTRB(r1.Right-cw-1,(r1.Height-cw)/2,r1.Right,(r1.Height+cw)/2);
			}
			SkinDraw.DrawRect1(g,SkinImage.checkbox,r1,i);
		}
	}

还重写了里面的事件，我可以不重写吗？

OnPaint()方法不是太懂。

看来这个比较难一点。

能把源码发给我一份吗？兄弟
