本文實例講述了C#中TreeView節點的自界說繪制辦法。分享給年夜家供年夜家參考。詳細以下:
if ((e.State & TreeNodeStates.Selected) != 0) { //演示為綠底白字 e.Graphics.FillRectangle(Brushes.DeepSkyBlue, e.Node.Bounds); Font nodeFont = e.Node.NodeFont; if (nodeFont == null) nodeFont = ((TreeView)sender).Font; e.Graphics.DrawString(e.Node.Text, nodeFont, Brushes.White, Rectangle.Inflate(e.Bounds, 2, 0)); } else { e.DrawDefault = true; } if ((e.State & TreeNodeStates.Focused) != 0) { using (Pen focusPen = new Pen(Color.Black)) { focusPen.DashStyle = System.Drawing.Drawing2D.DashStyle.Dot; Rectangle focusBounds = e.Node.Bounds; focusBounds.Size = new Size(focusBounds.Width - 1, focusBounds.Height - 1); e.Graphics.DrawRectangle(focusPen, focusBounds); } }
願望本文所述對年夜家的C#法式設計有所贊助。
