procedure TForm1.Button1Click(Sender: TObject);
const
iHtoH = 20; //行間距
iWtoW = 10; //列間距
iPerLine = 6;//每行個數
iWidth = 80; //按鈕寬度
var
I : integer;
begin
//算法:動態創建30個按鈕,每行6個共5行,順序排列,顯示在ScrollBox上
for I := 1 to 30 do
with TButton.Create(Self) do begin
Name := 'Btn' + InttoStr(I);
Parent := Self.ScrollBox1;
Caption := Name;
Top := iHtoH + (30+iHtoH) * (I div iPerLine - integer((I mod iPerLine)=0));
Left := iWtoW + (iWidth+iWtoW) * ((I-1) mod iPerLine);
Show;
end;
end;//或許可以繼續精練一下
效果如下:

在CSDN解答問題後整理以下代碼:
const
iHtoH = 20; //行間距
iWtoW = 10; //列間距
iWidth = 80; //按鈕寬度
iCount = 30; //按鈕個數
var
iPerLine : integer;//每行個數
BtnArr : array[1..iCount] of TButton;
procedure TForm1.FormCreate(Sender: TObject);
var
I : integer;
begin
iPerLine := Self.ClientWidth div (iWidth+iWtoW);
for I := 1 to iCount do begin
BtnArr[I] := TButton.Create(Self);
with BtnArr[I] do begin
Name := 'Btn' + InttoStr(I);
Parent := Self;
Caption := Name;
Top := iHtoH + (30+iHtoH) * (I div iPerLine - integer((I mod iPerLine)=0));
Left := iWtoW + (iWidth+iWtoW) * ((I-1) mod iPerLine);
Show;
end;
end;
end;
procedure TForm1.FormResize(Sender: TObject);
var
I : integer;
begin
iPerLine := Self.ClientWidth div (iWidth+iWtoW);
for I := 1 to iCount do
with BtnArr[I] do begin
Top := iHtoH + (30+iHtoH) * (I div iPerLine - integer((I mod iPerLine)=0));
Left := iWtoW + (iWidth+iWtoW) * ((I-1) mod iPerLine);
end;
end;
