Delphi，标签最大字符数

Question

TLabel 的最大字符数为 255(ShortString)，但我需要更多。我应该使用什么？

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，这很有效。 在代码中，字符串文字不能超过 255 个字符。但这不是问题。就这么做

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，但单个字符串文字(源代码中 ' 和 ' 之间的文本)不能超过 255 个字符。要构造更长的字符串， 使用字符串连接运算符 (+) 连接较短的字符串文字。
