控件位置确定(100分)

最近编个系统时遇到个问题,根据数据库中的记录来生成控件时,控件的位置很难放好,
我的要求是比如有12个记录也即我要生成12对控件,每对是label edit,位置是每一行放
4对像下面一样:
label1 edit1,label2 edit2,label3 edit3,label4 edit4
label5 edit5,label6 edit6,label7 edit7,label8 edit8
label9 edit9,label10 edit10,label11 edit11,label12 edit12
请各位delphi高手帮忙,高手相送!!!!!!!!!!!!!!!

高手请进

像这样做就可以了。
var
tmpLeft, tmpTop,i, j: integer;//
begin
tmpLeft:= 20;//第一个控件的左部位置,你可修改
tmpTop:= 20;//第一个控件的顶部位置,你可修改
i:= 0;
while i<12 do
begin
j:= 0;
while j<8 do
begin
if odd(j) then
begin
生成一个Label控件；
Labe.Left:= tmpLeft;
Label.Top:= tmpTop;
tmpLeft:= tmpLeft + Label.Width;
end
else
begin
生成一个Edit控件；
Edit.Left:= tmpLeft;
Edit.Top:= tmpTop;
tmpLeft:= tmpLeft + Edit.Width;
end;
j:= j + 1;
end;
tmpLeft:=20;//准备生成下一行控件
tmpTop:= tmpTop+30;//30为行间距，你可修改
j:= 0;
i:= i + 1;
end;

再次关注:
如果有11个记录

label1 edit1,label2 edit2,label3 edit3,label4 edit4
label5 edit5,label6 edit6,label7 edit7,label8 edit8
label9 edit9,label10 edit10,label11 edit11
这样怎么办

给你参考一段代码,我就是这样做的,产生后的是系统默认位置,在界面上还可
以由用户拖动
CREATE proc DPosDefalt

as
--控件默认位置计算
--用户每增加一个字段,都要调用此方法来确定此控件的位置,并要增加一个相应的标签
--取得最后一个控件的位置,并看是否处在最后一个位置上,
--如是:标签:高=高+24,左=8,宽=20--文本框--高=高+24,左=28,宽=150
--不是:标签:高=高,左=左+2,宽=20--文本框--高=高,左=左+2,宽=150
--取得最后一行
declare @top int
declare @left int
declare @width int
declare @lst bit
declare @lst1 bit
declare @id int
declare @name varchar(20)
declare @oldname varchar(20)
--增加一个标签
select @top=0,@left=0,@width=0,@lst=0
select top 1
@top=isnull(高,0),
@left=isnull(左,0),
@width=isnull(宽,0),
@lst=isnull(lst,0),
@name=isnull(名称,'')
from ditempos order by id desc
if @name is null
begin
select top 1 @name=名称 from ditemdefine order by id
end
if @top=0 set @top=24
if @left=0 set @left=8
set @oldname=@name
if @lst=1--最后一个标签已处在最后一个位置
begin
set @name=@name+'Lb'
if @left+8>=488
set @lst1=1
else
set @lst1=0
select @top=@top+24,
@left=8,
@width=20
insert ditempos(名称,高,左,宽,lst,类型)
values(@name,@top,@left,@width,0,'Label')

end
else begin--最后一个标签已不在最后一个位置
set @name=@name+'Lb'
if @left+@width+2>=488
set @lst1=1
else
set @lst1=0
select @top=@top,
@left=@left+@width+2,
@width=20
insert ditempos(名称,高,左,宽,lst,类型)
values(@name,@top,@left,@width,@lst1,'Label')
end
select @top=0,@left=0,@width=0,@lst=0
--增加一个文本框
select top 1
@top=isnull(高,0),
@left=isnull(左,0),
@width=isnull(宽,0),
@lst=lst
from ditempos order by id desc
if @top=0 set @top=24

else

select @top=@top+24,
@left=8,
@width=150
insert ditempos(名称,高,左,宽,lst,类型)
values(@oldname,@top,@left,@width,0,'DBEdit')
end
else begin--不在最后一个位置
if @left+8>=488
set @lst1=1
else
set @lst1=0
select @top=@top,
@left=@left+2+@width,
@width=150
insert ditempos(名称,高,左,宽,lst,类型)
values(@Oldname,@top,@left,@width,@lst1,'DBEdit')

若你有11个记录，或记录数不确定时，
你只要在程序中的设个变量count,
count:=Table1.RecordCount;
再把程序中的常量12换成这个变量不就解决了。
按照这种思路，再设个变量作为字段数，
这样,你不但可以动态生成每行的控件数，
也可以动态生成总的控件的行数，

我试试再说
