C#WinForm窗体内Panel容器中嵌入子窗体、程序主窗体设计例子

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

C#自定义Winform无边框窗体

主要思路

 this.IsMdiContainer=true;//设置父窗体是容器
 Son mySon=new Son();//实例化子窗体
 mySon.MdiParent=this;//设置窗体的父子关系
 mySon.Parent=pnl1;//设置子窗体的容器为父窗体中的Panel
 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

         /// <summary>
         /// 显示窗体
         /// </summary>
         /// <param name="panel"></param>
         /// <param name="frm"></param>
         public void ShowForm(System.Windows.Forms.Panel panel, System.Windows.Forms.Form frm)
         {
             lock (this)
             {
                 try
                 {
                     if (this.currentForm != null && this.currentForm == frm)
                     {
                         return;
                     }
                     else if (this.currentForm != null)
                     {
                         if (this.ActiveMdiChild != null)
                         {
                             this.ActiveMdiChild.Hide();
                         }
                     }
                     this.currentForm = frm;
                     frm.TopLevel = false;
                     frm.MdiParent = this;
                     panel.Controls.Clear();
                     panel.Controls.Add(frm);
                     frm.Show();
                     frm.Dock = System.Windows.Forms.DockStyle.Fill;
                     this.Refresh();
                     foreach (Control item in frm.Controls)
                     {
                         item.Focus();
                         break;
                     }
                 }
                 catch (System.Exception ex)
                 {
                     //
                 }
             }
         }

子窗体静态字段

         /// <summary>
         /// 子窗体界面单例元素
         /// </summary>
         public static Form1 form1 = null;
         public static Form2 form2 = null;
         public static Form3 form3 = null;
         public static Form4 form4 = null;
         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

             //实例化子窗体界面
             form1 = Form1.GetIntance;
             form2 = Form2.GetIntance;
             form3 = Form3.GetIntance;
             form4 = Form4.GetIntance;
             form5 = Form5.GetIntance;

窗体单例

         private static MainForm formInstance;
         public static MainForm GetIntance
         {
             get
             {
                 if (formInstance != null)
                 {
                     return formInstance;
                 }
                 else
                 {
                     formInstance = new MainForm();
                     return formInstance;
                 }
             }
         }

初始化按钮状态

         private bool initButton()
         {
             try
             {
                 this.button1.BackColor = Color.FromArgb(, , );
                 this.button2.BackColor = Color.FromArgb(, , );
                 this.button3.BackColor = Color.FromArgb(, , );
                 this.button4.BackColor = Color.FromArgb(, , );
                 this.button5.BackColor = Color.FromArgb(, , );
                 this.button6.BackColor = Color.FromArgb(, , );
                 this.button7.BackColor = Color.FromArgb(, , );
                 this.button8.BackColor = Color.FromArgb(, , );
                 this.button9.BackColor = Color.FromArgb(, , );
                 this.button10.BackColor = Color.FromArgb(, , );
                 this.button11.BackColor = Color.FromArgb(, , );
             }
             catch (Exception ex)
             {
                 return false;
             }
             return true;
         }

导航按钮单击切换事件

         private void button1_Click(object sender, EventArgs e)
         {
             try
             {
                 this.initButton();
                 this.button1.BackColor = Color.FromArgb(, , );
                 Monitor.Enter(this.lockObj);
                 if (!formSwitchFlag)
                 {
                     formSwitchFlag = true;
                     this.ShowForm(pnlCenter,form1);
                     formSwitchFlag = false;
                 }
                 else
                 {
                     return;
                 }
             }
             catch (System.Exception ex)
             {
                 //
             }
             finally
             {
                 Monitor.Exit(this.lockObj);
             }
         }
