各位高人：
怎么才能在StringGrid的Drawcell事件里合并单元格并且在合并的单元格上显示字符呢？
我已经在网上抄袭了一段合并单元格的例子 合并是成功了但是 往合并的单元格上写字符串的时候
怎么没显示啊 ！！ 偶千思不得其解 望各位江湖老大们帮帮偶这个小弟啊！！ 谢谢 谢谢 偶在线。。。。。

抄袭了一段合并单元格的例子贴出来看看

[xiangtianwen]

procedure TForm1.StringGrid1DrawCell(Sender: TObject; ACol, ARow: Integer;
Rect: TRect; State: TGridDrawState);
var
FrameFlags1, FrameFlags2: DWORD;
TmpR:TRect;
Str:String;
begin
if (ACol=0) and (ARow=3) then //第四行第一列
begin
TmpR:=StringGrid1.CellRect(3,3);//把区域扩大到第四行第四列.
Rect.Right:=TmpR.Right;
(Sender as TstringGrid).Canvas.FillRect(Rect);
(Sender as TstringGrid).Canvas.TextOut(rect.Left,Rect.Top+3,'我我');
end;
if (ACol in [1..3]) and (ARow=3) then //如果是第四行第2,3,4列就不画了,因为在第一列已经画了.
Exit;
FrameFlags1 := 0;
FrameFlags2 := 0;
if goFixedVertLine in StringGrid1.Options then
begin
FrameFlags1 := BF_RIGHT;
FrameFlags2 := BF_LEFT;
end;
if goFixedHorzLine in StringGrid1.Options then
begin
FrameFlags1 := FrameFlags1 or BF_BOTTOM;
FrameFlags2 := FrameFlags2 or BF_TOP;
end;
if gdFixed in State then
begin
Str:='Test';
StringGrid1.Canvas.Brush.Color:=StringGrid1.FixedColor;
StringGrid1.Canvas.FillRect(Rect);
DrawEdge(StringGrid1.Canvas.Handle, Rect, BDR_RAISEDINNER, FrameFlags1);
DrawEdge(StringGrid1.Canvas.Handle, Rect, BDR_RAISEDINNER, FrameFlags2);
DrawText(StringGrid1.Canvas.Handle,PChar(Str),Length(Str),Rect,DT_SINGLELINE or DT_VCENTER or DT_CENTER);
end else
begin
Str:=StringGrid1.Cells[acol,arow];
StringGrid1.Canvas.Brush.Color:=StringGrid1.Color;
StringGrid1.Canvas.FillRect(Rect);
DrawEdge(StringGrid1.Canvas.Handle, Rect, BDR_RAISEDINNER, FrameFlags1);
DrawEdge(StringGrid1.Canvas.Handle, Rect, BDR_RAISEDINNER, FrameFlags2);
DrawText(StringGrid1.Canvas.Handle,PChar(Str),Length(Str),Rect,DT_SINGLELINE or DT_VCENTER or DT_CENTER);
end;

end;

效果一般般 但是没办法啊！！偶水平太菜了 不会重写Grid类

[xiangtianwen]

怎么没人啊！！！没人会么？失望。。。。。。。。。。。。。

可以用一下advstringgrid

谢谢各位江湖大哥 偶已经解决了该问题 偶使用了EasyGrid 在也不用受StringGrid 的折磨啦
