本篇章节讲解C#更改tabControl选项卡颜色的方法。分享给大家供大家参考,具体如下: private void Form1_Load(object sender,EventArgs e) { this.tabControl1.DrawMode = System.Windows.Forms.TabDrawMode.OwnerDrawFixed; this.tabControl1.DrawItem += new DrawItemEventHandler(this.tabControl1_DrawItem); } private void tabControl1_DrawItem(object sender,System.Windows.Forms.DrawItemEventArgs e) { StringFormat sf = new StringFormat(); sf.LineAlignment = StringAlignment.Center; sf.Alignment = StringAlignment.Center; if (e.Index == tabControl1.SelectedIndex) e.Graphics.FillRectangle(Brushes.Red,e.Bounds.X,e.Bounds.Y,e.Bounds.Width,e.Bounds.Height); else e.Graphics.FillRectangle(Brushes.White,e.Bounds.Height); e.Graphics.DrawString(((TabControl)sender).TabPages[e.Index].Text,System.Windows.Forms.SystemInformation.MenuFont,new SolidBrush(Color.Black),e.Bounds,sf); } 1.在Form类的构造函数中添加下列语句: this.tabControl1.DrawMode = System.Windows.Forms.TabDrawMode.OwnerDrawFixed; this.tabControl1.DrawItem += new DrawItemEventHandler(this.tabControl1_DrawItem); 2.实现下列函数: private void tabControl1_DrawItem(object sender,System.Windows.Forms.DrawItemEventArgs e) { Font fntTab; Brush bshBack; Brush bshFore; if ( e.Index == this.tabControl1.SelectedIndex) { fntTab = new Font(e.Font,FontStyle.Bold); bshBack = new System.Drawing.Drawing2D.LinearGradientBrush(e.Bounds,SystemColors.Control,System.Drawing.Drawing2D.LinearGradientMode.BackwardDiagonal); bshFore = Brushes.Black; } else { fntTab = e.Font; bshBack = new SolidBrush(Color.Blue ); bshFore = new SolidBrush(Color.Black); } string tabName = this.tabControl1.TabPages[e.Index].Text; StringFormat sftTab = new StringFormat(); e.Graphics.FillRectangle(bshBack,e.Bounds); Rectangle recTab = e.Bounds; recTab = new Rectangle( recTab.X,recTab.Y + 4,recTab.Width,recTab.Height - 4); e.Graphics.DrawString(tabName,fntTab,bshFore,recTab,sftTab); } 更多关于C#相关内容感兴趣的读者可查看本站专题:《C#数据结构与算法教程》、《C#常见控件用法教程》、《C#面向对象程序设计入门教程》及《C#程序设计之线程使用技巧总结》 希望本文所述对大家C#程序设计有所帮助。 (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
