RzGroupBar 的RzGroup尺寸大小调不了，怎么办？急

var FHFRzGroup: array of TRzGroup;
       FHFRzGroup[i] := TRzGroup.Create( Self );
       FHFRzGroup[i].Parent := RzGroupBar1;
       FHFRzGroup[i].Caption := Flink.ADOQueryHFJL.FieldByName('标题').asstring;
       FHFRzGroup[i].opened:=true;
       FHFRzGroup[i].openedHeight := 150;
       FHFRzGroup[i].Height := 150;
       RzGroupBar1.AddGroup(FHFRzGroup[i]);设置了Height := 150;可显示还是默认大小，找不到原因，烦死了
