最后一列边框没显示出来.(⊙o⊙)…

试了几种办法都不行, 暂时先这样用了,对我来说不影响,后续有其他方案在修改更新.

                    var nSubItem = lvcd.iSubItem;
                    
                    var rc = owner.getItemRect(nItem,nSubItem);
                    cvs.pen.color = 0xebebeb; // 定义画笔的颜色
                    cvs.drawEdge(rc);
                    lvcd.update()
                        
                    cvs.destroy();
                    return 0/*_CDRF_DODEFAULT*/
                }
        }



winform.show() 
win.loopMessage();

用下面的代码替换画edge可以实现画任意颜色

cvs.pen.color = 0xff0000//0xebebeb; // 定义画笔的颜色
                    //cvs.drawEdge(rc);
                    //左上到右上
                    cvs.moveTo(rc.left, rc.top); // 落笔
                cvs.lineTo(rc.right, rc.top); // 提笔
                    //右上到右下
                    cvs.moveTo(rc.right, rc.top); // 落笔
                cvs.lineTo(rc.right, rc.bottom); // 提笔
                    //右下到左下
                    cvs.moveTo(rc.right, rc.bottom); // 落笔
                cvs.lineTo(rc.left, rc.bottom); // 提笔
                //左下到左上
                    cvs.moveTo(rc.left, rc.bottom); // 落笔
                cvs.lineTo(rc.left, rc.top); // 提笔
