示例代码:



uses GdiPlus;procedure TForm1.StringGrid1DrawCell(Sender: TObject; ACol, ARow: Integer; Rect: TRect; State: TGridDrawState);var Graphics: IGPGraphics; Pen: IGPPen;begin //获取绘图表面 Graphics := TGPGraphics.Create(TWinControl(Sender).Handle); //设置绘图质量以消除锯齿 Graphics.SmoothingMode := SmoothingModeHighQuality; //画笔 Pen := TGPPen.Create(TGPColor.Red, 1); //随便画了两条线 Graphics.DrawLine(Pen, Rect.Left, Rect.Top, Rect.Right, Rect.Bottom); Graphics.DrawLine(Pen, Rect.Right, Rect.Top, Rect.Left, Rect.Bottom);end;
