Winform自定义控件（button）模拟缩小，放大，关闭窗口

格式介绍：

Webdings是一个TrueType的dingbat字体，于1997年发表，搭载在其后的Microsoft Windows视窗系统内，大多的字形都没有Unicode的相对字。

这里我们用0（最小化）,1（放大）,2（缩放）,r（关闭）模拟对应窗口按键。

废话不多说直接上代码：

  public partial class UiconButton : Button
    {
        public UiconButton()
        {
            InitializeComponent();
            //尺寸 字体 字号 
            this.Size = new Size(30, 30);
            this.Font = new Font("Webdings", 10.8f);
            this.FlatStyle = FlatStyle.Flat;
            this.FlatAppearance.BorderSize = 0;
            this.Text = "0";
            this.ForeColor = Color.Silver;
            this.BackColor = Color.Transparent;
        }

        protected override void OnMouseEnter(EventArgs e)
        {
            base.OnMouseEnter(e);
            this.BackColor = Color.FromArgb(53, 61, 134);
        }

        protected override void OnMouseLeave(EventArgs e)
        {
            base.OnMouseLeave(e);
            this.BackColor = Color.Transparent;
        }

        /// <summary>
        /// 不显示聚焦框 
        /// </summary>
        protected override bool ShowFocusCues
        {
            get { return false; }
        }
    }

注意：创建用户控件后需要把继承类改成 Button 然后删除这行才能使用

使用方法：

修改对应文本即可

主窗口使用代码：

 /// <summary>
        /// 窗口缩小化
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void ButMin_Click(object sender, EventArgs e)
        {
            if (this.WindowState != FormWindowState.Minimized) {
                this.WindowState = FormWindowState.Minimized;
            }
        }
        /// <summary>
        /// 窗口最大化
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void ButMax_Click(object sender, EventArgs e)
        {
            if (this.WindowState == FormWindowState.Maximized)
            {
                this.WindowState = FormWindowState.Normal;
                this.ButMax.Text = "1";
            }
            else {
                this.WindowState = FormWindowState.Maximized;
                this.ButMax.Text = "2";
            }
        }
        /// <summary>
        /// 关闭窗口
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void ButClose_Click(object sender, EventArgs e)
        {
            Application.Exit();
        }
        /// <summary>
        /// 窗口关闭事件
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void FormMain_FormClosing(object sender, FormClosingEventArgs e)
        {
            if (MessageBox.Show("是否退出界面?", "提示",
               MessageBoxButtons.OKCancel, MessageBoxIcon.Question,
               MessageBoxDefaultButton.Button2) == DialogResult.OK)
            {
                Application.ExitThread();
            }
            else e.Cancel = true;
        }
