創建一個主窗體（Formmain）、兩個副窗體（Form1,Form2）;在主窗體中分別添加一個menuStrip控件、tabControl控件,並在menu控件上添加一個主菜單和兩個子菜單,如下圖: 繼而,選中tabControl控件屬性修改 DrawMode = OwnerDrawFixed,再根據如下代碼添加即可: public void Add_TabPage(string str, Form myForm) { if (tabControlCheckHave(this.MainTabControl, str)) { return; } else { MainTabControl.TabPages.Add(str); MainTabControl.SelectTab(MainTabControl.TabPages.Count - 1); myForm.FormBorderStyle = FormBorderStyle.None; myForm.Dock = DockStyle.Fill; myForm.TopLevel = false; myForm.Show(); myForm.Parent = MainTabControl.SelectedTab; } } public bool tabControlCheckHave(System.Windows.Forms.TabControl tab, String tabName) { for (int i = 0; i < tab.TabCount; i++) { if (tab.TabPages[i].Text == tabName) { tab.SelectedIndex = i; return true; } } return false; } private void form1ToolStripMenuItem_Click(object sender, EventArgs e) { Form1 f1= new Form1(); Add_TabPage("f1中華人民共和國窗體 ", f1); } private void form2ToolStripMenuItem_Click(object sender, EventArgs e) { Form2 f2 = new Form2(); Add_TabPage("f2朝鮮窗體 ", f2); } private void MainTabControl_DrawItem(object sender, DrawItemEventArgs e) { /*如果將 DrawMode 屬性設置為 OwnerDrawFixed， 則每當 TabControl 需要繪制它的一個選項卡時，它就會引發 DrawItem 事件*/ try { this.MainTabControl.TabPages[e.Index].BackColor = Color.LightBlue; Rectangle tabRect = this.MainTabControl.GetTabRect(e.Index); e.Graphics.DrawString(this.MainTabControl.TabPages[e.Index].Text, this.Font, SystemBrushes.ControlText, (float)(tabRect.X + 2), (float)(tabRect.Y + 2)); using (Pen pen = new Pen(Color.White)) { tabRect.Offset(tabRect.Width - 15, 2); tabRect.Width = 15; tabRect.Height = 15; e.Graphics.DrawRectangle(pen, tabRect); } Color color = (e.State == DrawItemState.Selected) ? Color.LightBlue : Color.White; using (Brush brush = new SolidBrush(color)) { e.Graphics.FillRectangle(brush, tabRect); } using (Pen pen2 = new Pen(Color.Red)) { Point point = new Point(tabRect.X + 3, tabRect.Y + 3); Point point2 = new Point((tabRect.X + tabRect.Width) - 3, (tabRect.Y + tabRect.Height) - 3); e.Graphics.DrawLine(pen2, point, point2); Point point3 = new Point(tabRect.X + 3, (tabRect.Y + tabRect.Height) - 3); Point point4 = new Point((tabRect.X + tabRect.Width) - 3, tabRect.Y + 3); e.Graphics.DrawLine(pen2, point3, point4); } e.Graphics.Dispose(); } catch (Exception ex) { MessageBox.Show(ex.Message); } } private void MainTabControl_MouseDown(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { www.2cto.com int x = e.X; int y = e.Y; Rectangle tabRect = this.MainTabControl.GetTabRect(this.MainTabControl.SelectedIndex); tabRect.Offset(tabRect.Width - 0x12, 2); tabRect.Width = 15; tabRect.Height = 15; if ((((x > tabRect.X) && (x < tabRect.Right)) && (y > tabRect.Y)) && (y < tabRect.Bottom)) { this.MainTabControl.TabPages.Remove(this.MainTabControl.SelectedTab); } } }
