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(0,255);int i2=rdm.Next(0,255);int i3=rdm.Next(0,255);
            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
