C#WinForm父级窗体内Panel容器中嵌入子窗体、程序主窗体设计例子

在项目开发中经常遇到父级窗体嵌入子窗体所以写了一个例子程序，顺便大概划分了下界面模块和配色，不足之处还望指点

主窗体窗体采用前面一篇博客设计扁平化窗体

主要思路

1 this.IsMdiContainer=true;//设置父窗体是容器2 Son mySon=new Son();//实例化子窗体3 mySon.MdiParent=this;//设置窗体的父子关系4 mySon.Parent=pnl1;//设置子窗体的容器为父窗体中的Panel5 mySon.Show();//显示子窗体，此句很重要，否则子窗体不会显示

窗体设计上中下结构，最顶部是导航栏，其次是Top窗体部分、中间是Center内容部分、最底部是bottom导航面板

可以专门写一个方法做显示窗体

1         ///  2         /// 显示窗体 3         /// 
 4         ///  5         ///  6         public void ShowForm(System.Windows.Forms.Panel panel, System.Windows.Forms.Form frm) 7         { 8             lock (this) 9             {10                 try11                 {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         }

子窗体静态字段

1         /// 2         /// 子窗体界面单例元素3         /// 
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;

构造初始化窗体这里每一个窗体都是一个单例保证窗体的唯一性

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

窗体单例

1         private static MainForm formInstance; 2         public static MainForm GetIntance 3         { 4             get 5             { 6                 if (formInstance != null) 7                 { 8                     return formInstance; 9                 }10                 else11                 {12                     formInstance = new MainForm();13                     return formInstance;14                 }15             }16         }

初始化按钮状态

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         }

导航按钮单击切换事件

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                 else15                 {16                     return;17                 }18             }19             catch (System.Exception ex)20             {21                 //22             }23             finally24             {25                 Monitor.Exit(this.lockObj);26             }27         }
