winform 控件开发1——复合控件

哈哈是不是丑死了？

做了一个不停变色的按钮，可以通过勾选checkbox停下来，代码如下：

复合控件果然简单呀，我都能学会~

 using System;
 using System.Collections.Generic;
 using System.ComponentModel;
 using System.Diagnostics;
 using System.Drawing;
 using System.Linq;
 using System.Text;
 using System.Threading.Tasks;
 using System.Windows.Forms;
 namespace ComponentComposite
 {
     [ToolboxBitmap(typeof(Timer))]
     public partial class Component1:UserControl
     {
         private Color _colFColor;
         private Color _colBColor;
         public Color colFColor { get { return _colFColor; } set { _colFColor = value; checkBox1.ForeColor = _colFColor; } }
         public Color colBColor { get { return _colBColor; } set { _colBColor = value; checkBox1.BackColor = _colBColor; } }
         public Component1()
         {
             InitializeComponent();
         }

         public Component1(IContainer container)
         {
             container.Add(this);

             InitializeComponent();
         }

         private void timer1_Tick(object sender, EventArgs e)
         {   Random rdm=new Random();
             int i1=rdm.Next(,);int i2=rdm.Next(,);int i3=rdm.Next(,);
             button1.BackColor = System.Drawing.Color.FromArgb(i1, i2, i3);
         }

         private void checkBox1_CheckedChanged(object sender, EventArgs e)
         {
             timer1.Enabled = (timer1.Enabled)?false:true;
         }
     }
 }

上午跟人家学了一个渐变按钮，

如图，现在试试可不可以组合。嗯可以组合，但是好像不是自动变化颜色的呀
