C#中TreeView节点的自定义绘制方法

本文实例讲述了c#中treeview节点的自定义绘制方法。分享给大家供大家参考。具体如下：

if ((e.state & treenodestates.selected) != 0)
{
 //演示为绿底白字
 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);
 }
}

希望本文所述对大家的c#程序设计有所帮助。
