TList的用法
TList是一个很好的东东，有了它我们不再去费尽心思地写什么列表类，直接用它就行了，下面的例子示范了怎样建立一个TList并插入两条记录，这些记录将输出在PaintBox上。
C++ Builder
请参照Delphi的例子
Delphi
procedure TForm1.FormButton1Click(Sender: TObject);
type
PMyList = ^AList;
AList = record
I: Integer;
C: Char;
end;
var
MyList: TList;
ARecord: PMyList;
B: Byte;
Y: Word;
begin
MyList := TList.Create;
New(ARecord);
ARecord^.I := 100;
ARecord^.C := Z;
MyList.Add(ARecord); //加入一个100的整数和Z字符
New(ARecord);
ARecord^.I := 200;
ARecord^.C := X;
MyList.Add(ARecord); //加入一个200的整数和X字符
Y := 10;
for B := 0 to (MyList.Count - 1) do
begin
ARecord := MyList.Items[B];
Canvas.TextOut(10, Y, IntToStr(ARecord^.I));
Y := Y + 30;
Canvas.TextOut(10, Y, ARecord^.C);
Y := Y + 30;
end;
for B := 0 to (MyList.Count - 1) do
begin
ARecord := MyList.Items[B];
Dispose(ARecord);
end;
MyList.Free;
end;
