Delphi，标签最大字符

Question

TLabel的最大字符数为255（ShortString），但我还需要更多。我该怎么用？

Answer 1

不，没有限制。我只是尝试使用一个包含1223个字符的字符串作为TLabel的标题，这是有效的。 在代码中，字符串文字不能超过255个字符。但这不是问题。只是做

Label1.Caption := 'This is a test. This is a test. This is a test.' + 
  'This is a test. This is a test. This is a test. This is a test.' +
  'This is a test. This is a test. This is a test. This is a test.' +
  'This is a test. This is a test. This is a test. This is a test.' +
  'This is a test. This is a test. This is a test. This is a test.' +
  'This is a test. This is a test. This is a test. This is a test.' +
  'This is a test. This is a test. This is a test. This is a test.';

您可以根据需要制作标题，但是单个字符串文字，源代码中的文字在'和'之间，不能超过255个字符。要构造一个更长的字符串， 使用字符串连接运算符（+）来连接较短的字符串文字。
