winform自定義標題條窗口

效果如下圖:

 

將窗口設爲無邊,增加一個panel,三個按鈕和一個label,屬性設置見下代碼,重點部分已註釋.

 private void InitializeComponent()
        {
            //標題條
            this.panel1 = new System.Windows.Forms.Panel();
            //窗口控制按鈕
            this.button1 = new System.Windows.Forms.Button();
            this.button2 = new System.Windows.Forms.Button();
            this.button3 = new System.Windows.Forms.Button();
            //窗口名標籤
            this.label1 = new System.Windows.Forms.Label();
            this.panel1.SuspendLayout();
            this.SuspendLayout();
            // 
            // panel1
            // 
            this.panel1.BackColor = System.Drawing.SystemColors.ButtonFace;

            // 
            // 關閉窗口按鈕設置
            // 
            this.button1.Dock = System.Windows.Forms.DockStyle.Right;
            //使按鈕無邊
            this.button1.FlatAppearance.BorderSize = 0;
            //使按鈕爲平式的外觀
            this.button1.FlatStyle = System.Windows.Forms.FlatStyle.Flat;

            this.button2.Location = new System.Drawing.Point(798, 0);
            this.button2.Margin = new System.Windows.Forms.Padding(0);
            this.button2.Name = "button2";
            this.button2.Size = new System.Drawing.Size(29, 29);
            this.button2.TabIndex = 2;

            this.button3.Size = new System.Drawing.Size(29, 29);
            this.button3.TabIndex = 3;
            this.button3.Text = "─";
            this.button3.UseVisualStyleBackColor = true;
            // 
            // label1
            // 
            this.label1.AutoSize = true;
            this.label1.Dock = System.Windows.Forms.DockStyle.Left;
            this.label1.FlatStyle = System.Windows.Forms.FlatStyle.Flat;
            this.label1.Location = new System.Drawing.Point(0, 0);
            this.label1.Margin = new System.Windows.Forms.Padding(0);
            this.label1.Name = "label1";
            this.label1.Padding = new System.Windows.Forms.Padding(0, 6, 0, 0);
            this.label1.Size = new System.Drawing.Size(77, 20);
            this.label1.TabIndex = 4;
            this.label1.Text = "ThinkAbout";
            this.label1.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;
            // 
            // Form1
            // 
            this.AutoScaleDimensions = new System.Drawing.SizeF(7F, 14F);
            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
            this.ClientSize = new System.Drawing.Size(853, 525);
            this.ControlBox = false;
            this.Controls.Add(this.panel1);
            this.Font = new System.Drawing.Font("宋體", 10.5F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(134)));
            //設置窗口無邊,這樣就不會顯示默認的控制按鈕了.
            this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
            this.Name = "Form1";
            this.Text = "Form1";
            this.Load += new System.EventHandler(this.Form1_Load);
            this.MouseDown += new System.Windows.Forms.MouseEventHandler(this.Form1_MouseDown);
            this.MouseMove += new System.Windows.Forms.MouseEventHandler(this.Form1_MouseMove);
            this.panel1.ResumeLayout(false);
            this.panel1.PerformLayout();
            this.ResumeLayout(false);

        }

編寫拖動窗口和關閉窗口的代碼.如下:

  public partial class Form1 : Form
    {
        Point LeftDown;
             
        public Form1()
        {
            InitializeComponent();
            LeftDown = new Point();

        }

        private void panel1_MouseDown(object sender, MouseEventArgs e)
        {
            LeftDown.X = e.X;
            LeftDown.Y = e.Y;
        }

        private void panel1_MouseMove(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left)
            {
                Point p = MousePosition;
                p.Offset(-LeftDown.X, -LeftDown.Y);
                Location = p;
            }
        }
    }
