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。
