C#WinForm窗體內Panel容器中嵌入子窗體、程序主窗體設計例子

C#WinForm父級窗體內Panel容器中嵌入子窗體、程序主窗體設計例子

在項目開發中經常遇到父級窗體嵌入子窗體所以寫了一個例子程序，順便大概划分了下界面模塊和配色，不足之處還望指點

主窗體窗體采用前面一篇博客設計扁平化窗體 

C#自定義Winform無邊框窗體

主要思路

1 this.IsMdiContainer=true;//設置父窗體是容器
2 Son mySon=new Son();//實例化子窗體
3 mySon.MdiParent=this;//設置窗體的父子關系
4 mySon.Parent=pnl1;//設置子窗體的容器為父窗體中的Panel
5 mySon.Show();//顯示子窗體，此句很重要，否則子窗體不會顯示

窗體設計上中下結構，最頂部是導航欄，其次是Top窗體部分、中間是Center內容部分、最底部是bottom導航面板

可以專門寫一個方法做顯示窗體

 1         /// <summary>
 2         /// 顯示窗體
 3         /// </summary>
 4         /// <param name="panel"></param>
 5         /// <param name="frm"></param>
 6         public void ShowForm(System.Windows.Forms.Panel panel, System.Windows.Forms.Form frm)
 7         {
 8             lock (this)
 9             {
10                 try
11                 {
12                     if (this.currentForm != null && this.currentForm == frm)
13                     {
14                         return;
15                     }
16                     else if (this.currentForm != null)
17                     {
18                         if (this.ActiveMdiChild != null)
19                         {
20                             this.ActiveMdiChild.Hide();
21                         }
22                     }
23                     this.currentForm = frm;
24                     frm.TopLevel = false;
25                     frm.MdiParent = this;
26                     panel.Controls.Clear();
27                     panel.Controls.Add(frm);
28                     frm.Show();
29                     frm.Dock = System.Windows.Forms.DockStyle.Fill;
30                     this.Refresh();
31                     foreach (Control item in frm.Controls)
32                     {
33                         item.Focus();
34                         break;
35                     }
36                 }
37                 catch (System.Exception ex)
38                 {
39                     //
40                 }
41             }
42         }

子窗體靜態字段

1         /// <summary>
2         /// 子窗體界面單例元素
3         /// </summary>
4         public static Form1 form1 = null;
5         public static Form2 form2 = null;
6         public static Form3 form3 = null;
7         public static Form4 form4 = null;
8         public static Form5 form5 = null;

構造初始化窗體 這里每一個窗體都是一個單例保證窗體的唯一性

1             //實例化子窗體界面
2             form1 = Form1.GetIntance;
3             form2 = Form2.GetIntance;
4             form3 = Form3.GetIntance;
5             form4 = Form4.GetIntance;
6             form5 = Form5.GetIntance;

窗體單例

 1         private static MainForm formInstance;
 2         public static MainForm GetIntance
 3         {
 4             get
 5             {
 6                 if (formInstance != null)
 7                 {
 8                     return formInstance;
 9                 }
10                 else
11                 {
12                     formInstance = new MainForm();
13                     return formInstance;
14                 }
15             }
16         }

初始化按鈕狀態

 1         private bool initButton()
 2         {
 3             try
 4             {
 5                 this.button1.BackColor = Color.FromArgb(53, 66, 83);
 6                 this.button2.BackColor = Color.FromArgb(53, 66, 83);
 7                 this.button3.BackColor = Color.FromArgb(53, 66, 83);
 8                 this.button4.BackColor = Color.FromArgb(53, 66, 83);
 9                 this.button5.BackColor = Color.FromArgb(53, 66, 83);
10                 this.button6.BackColor = Color.FromArgb(53, 66, 83);
11                 this.button7.BackColor = Color.FromArgb(53, 66, 83);
12                 this.button8.BackColor = Color.FromArgb(53, 66, 83);
13                 this.button9.BackColor = Color.FromArgb(53, 66, 83);
14                 this.button10.BackColor = Color.FromArgb(53, 66, 83);
15                 this.button11.BackColor = Color.FromArgb(53, 66, 83);
16             }
17             catch (Exception ex)
18             {
19                 return false;
20             }
21             return true;
22         }

導航按鈕單擊切換事件

 1         private void button1_Click(object sender, EventArgs e)
 2         {
 3             try
 4             {
 5                 this.initButton();
 6                 this.button1.BackColor = Color.FromArgb(95, 129, 174);
 7                 Monitor.Enter(this.lockObj);
 8                 if (!formSwitchFlag)
 9                 {
10                     formSwitchFlag = true;
11                     this.ShowForm(pnlCenter,form1);
12                     formSwitchFlag = false;
13                 }
14                 else
15                 {
16                     return;
17                 }
18             }
19             catch (System.Exception ex)
20             {
21                 //
22             }
23             finally
24             {
25                 Monitor.Exit(this.lockObj);
26             }
27         }
