请问：如何动态创建报表？

[WWWWA]

在一个报表中只有一个DETAILBAND，数人QRLABEL、QRTEXT，
请问如何在程序中动态设置？
谢谢！

设置什么

[mengli1]

简单,你自己创建QRLABEL,自己来控制写.我以前做的是一个鞋业领料单,中间有许多SIZE是
空的,要将这些空的去掉,后面的往前靠,而且分三排.用DataSet来做根本不可能,就自己写
着来控制就行了.部分代码如下:你看了应该就知道怎么做了.用QuickRep完全能够做到.

procedure TFrmQrt.CreateQRTxt;//动态建立各QR控件,只建立一次,在准备预览或打印之前.
var i,j:integer;
begin
SetLength(QRtxt,5,txtTotal);
for i:=0 to 4 do
for j:=0 to txtTotal-1 do
begin
QRtxt[i,j]:=TQRLabel.Create(Self);
QRtxt[i,j].Parent:=DetailBand1;
QRtxt[i,j].Caption:='';
QRtxt[i,j].AutoSize:=False;
QRtxt[i,j].Width:=txtWidth;
QRtxt[i,j].Height:=txtHeight;
QRtxt[i,j].Font.Name:='新細明體';
QRtxt[i,j].Font.Size:=11;
end;

QRtxt[0,i].Alignment:=taCenter;

QRtxt[1,i].Alignment:=taCenter;
DrawLine;
