C#自定義Winform無邊框窗體

C#自定義Winform無邊框窗體

　　在實際項目中，WinForm窗體或者控件不能知足要求，因此就須要本身設計窗體等，固然設計界面能夠用的東西不少，例如WPF、或者一些第三方的庫等。本例中將採用WinForm設計一個扁平美觀的窗體。

上一篇中咱們製做了一個button按鈕控件，恰好本例可採用    

須要的能夠參考：C#自定義Button按鈕控件

窗體效果：

接下來就是窗體的設計

1.添加一個窗體繼承原來的窗體Form

1 public partial class FormEX : Form

2.添加窗體屬性

 1      /// <summary>
 2         /// 是否容許最大化  3         /// </summary>
 4         private bool maxVisible = true;  5         [Description("是否容許最大化")]  6         public bool MaxVisible  7  {  8             get { return maxVisible; }  9             set
10  { 11                 maxVisible = value; 12                 if (!maxVisible) 13  { 14                     this.btnEXMin.Location = new System.Drawing.Point(this.btnEXMax.Location.X, 12); 15                     this.btnEXMax.Visible = false; 16  } 17                 else
18  { 19                     this.btnEXMin.Location = new System.Drawing.Point(this.btnEXMax.Location.X - 20, 12); 20                     this.btnEXMax.Visible = true; 21  } 22  } 23  } 24 
25 
26         /// <summary>
27         /// 窗體標題 28         /// </summary>
29         private string titleText; 30         [Description("窗體標題")] 31         public string TitleText 32  { 33             get { return titleText; } 34             set
35  { 36                 titleText = value; 37                 title.Text = titleText; 38 
39  } 40  } 41         /// <summary>
42         /// 窗體標題是否顯示 43         /// </summary>
44         private bool titleVisible = true; 45         [Description("窗體標題是否顯示")] 46         public bool TitleVisible 47  { 48             get { return titleVisible; } 49             set
50  { 51                 titleVisible = value; 52                 title.Visible = titleVisible; 53  } 54  } 55 
56         /// <summary>
57         /// 窗口默認大小 58         /// FormSize.NORMAL OR FormSize.MAX 59         /// </summary>
60         private FormSize defaultFormSize = FormSize.NORMAL; 61         [Description("窗口默認大小")] 62         public FormSize DefaultFormSize 63  { 64             get { return defaultFormSize; } 65             set
66  { 67                 defaultFormSize = value; 68                 if (defaultFormSize == FormSize.MAX) 69  { 70                     //防止遮擋任務欄
71                     this.MaximumSize = new Size(Screen.PrimaryScreen.WorkingArea.Width, Screen.PrimaryScreen.WorkingArea.Height); 72                     this.WindowState = FormWindowState.Maximized; 73                     //最大化圖標切換
74                     this.btnEXMax.ImageDefault = global::BenNHControl.Properties.Resources.MaxNormal; 75  } 76  } 77         }

3.窗體大小自由更改

1         const int WM_NCHITTEST = 0x0084; 2         const int HTLEFT = 10;      //左邊界
3         const int HTRIGHT = 11;     //右邊界
4         const int HTTOP = 12;       //上邊界
5         const int HTTOPLEFT = 13;   //左上角
6         const int HTTOPRIGHT = 14;  //右上角
7         const int HTBOTTOM = 15;    //下邊界
8         const int HTBOTTOMLEFT = 0x10;    //左下角
9         const int HTBOTTOMRIGHT = 17;     //右下角

protected override void WndProc(ref Message m) { switch (m.Msg) { case WM_NCHITTEST: base.WndProc(ref m); Point vPoint = new Point((int)m.LParam & 0xFFFF, (int)m.LParam >> 16 & 0xFFFF); vPoint = PointToClient(vPoint); if (vPoint.X <= 5) if (vPoint.Y <= 5) m.Result = (IntPtr)HTTOPLEFT; else if (vPoint.Y >= ClientSize.Height - 5) m.Result = (IntPtr)HTBOTTOMLEFT; else m.Result = (IntPtr)HTLEFT; else if (vPoint.X >= ClientSize.Width - 5) if (vPoint.Y <= 5) m.Result = (IntPtr)HTTOPRIGHT; else if (vPoint.Y >= ClientSize.Height - 5) m.Result = (IntPtr)HTBOTTOMRIGHT; else m.Result = (IntPtr)HTRIGHT; else if (vPoint.Y <= 5) m.Result = (IntPtr)HTTOP; else if (vPoint.Y >= ClientSize.Height - 5) m.Result = (IntPtr)HTBOTTOM; break; default: base.WndProc(ref m); break; } }

4.窗體按鈕等事件添加

 1  /// <summary>
 2         /// 最小化按鈕事件  3         /// </summary>
 4         /// <param name="sender"></param>
 5         /// <param name="e"></param>
 6         private void btnEXMin_ButtonClick(object sender, EventArgs e)  7  {  8             this.WindowState = FormWindowState.Minimized;  9  } 10 
11         /// <summary>
12         /// 最大化按鈕事件 13         /// </summary>
14         /// <param name="sender"></param>
15         /// <param name="e"></param>
16         private void btnEXMax_ButtonClick(object sender, EventArgs e) 17  { 18             this.MaxNormalSwitch(); 19  } 20 
21         /// <summary>
22         /// 關閉按鈕事件 23         /// </summary>
24         /// <param name="sender"></param>
25         /// <param name="e"></param>
26         private void btnEXClose_ButtonClick(object sender, EventArgs e) 27  { 28             this.Close(); 29  } 30 
31         /// <summary>
32         /// 鼠標按下標題欄 33         /// </summary>
34         /// <param name="sender"></param>
35         /// <param name="e"></param>
36         private void titleBar_MouseDown(object sender, MouseEventArgs e) 37  { 38             mPoint = new Point(e.X, e.Y); 39  } 40 
41         /// <summary>
42         /// 鼠標在移動 43         /// </summary>
44         /// <param name="sender"></param>
45         /// <param name="e"></param>
46         private void titleBar_MouseMove(object sender, MouseEventArgs e) 47  { 48             if (e.Button == MouseButtons.Left) 49  { 50                 this.Location = new Point(this.Location.X + e.X - mPoint.X, this.Location.Y + e.Y - mPoint.Y); 51  } 52  } 53 
54         private void titleBar_DoubleClick(object sender, EventArgs e) 55  { 56             this.MaxNormalSwitch(); 57  } 58 
59 
60         /// <summary>
61         /// 最大化和正常狀態切換 62         /// </summary>
63         private void MaxNormalSwitch() 64  { 65             if (this.WindowState == FormWindowState.Maximized)//若是當前狀態是最大化狀態 則窗體須要恢復默認大小
66  { 67                 this.WindowState = FormWindowState.Normal; 68                 // 69                 this.btnEXMax.ImageDefault = global::BenNHControl.Properties.Resources.Max; 70  } 71             else
72  { 73                 //防止遮擋任務欄
74                 this.MaximumSize = new Size(Screen.PrimaryScreen.WorkingArea.Width, Screen.PrimaryScreen.WorkingArea.Height); 75                 this.WindowState = FormWindowState.Maximized; 76                 //最大化圖標切換
77                 this.btnEXMax.ImageDefault = global::BenNHControl.Properties.Resources.MaxNormal; 78  } 79             this.Invalidate();//使重繪
80  } 81 
82         private void FormEX_Resize(object sender, EventArgs e) 83  { 84             this.Invalidate();//使重繪
85         }
