为什么TObject中的"T"前缀？

Question

在声明类等时,"T" TObject代表什么？模板？

例:

procedure TfrmMain.CaptureInfo1Click(Sender: TObject);
begin
  frmCapture.Show;
end;

Answer 1

德尔福有许多官方批准的前缀.
这些都是Borland惯例,并不是由编译器强制执行的.

Prefix | Used for | Notes
-------+----------+---------------------------------------------
   T   | types    | Denotes a structured type, class or record
   I   |interfaces| For interfaces, e.g. IInterface
   F   | Field    | Private Field in a class or record
  xx   | enum     | Enumeration members have a 2 char prefix
       |          | e.g.  fsBold, fsItalic for the TFontStyle enum  
   A   | params   | deprecated ! All method params at one point started with an `A`.
                    this convention is no longer encouraged. 

Note that the capitalization is as shown. 

Delphi使用前缀的原因是该语言不区分大小写,因此使用ALLCAPS作为常量和类型的前导上限的C/Java技巧不起作用.

Object Pascal样式指南中概述了所有这些以及更多内容,更具体地说,是命名约定部分.
