1、QString中的两个函数 1.QString QString::simplified() const Returns a string that has whitespace removed from the start and the end, and that has each sequence of internal whitespace replaced with a single space. 返回一个字符串,移除从一开始到结尾的空白,每个序列内部的空格替换为一个空格(头尾的都去掉了) 举个例子: QString str = " lots\t of\nwhitespace\r\n "; str = str.simplified(); // str == "lots of whitespace"; '\t', '\n', '\v', '\f', '\r', ' ' 都属于空白的处理范围。 2.QString QString::trimmed() const Returns a string that has whitespace removed from the start and the end. 返回一个字符串,移除从一开始到结尾的空白。也去掉头尾的空白 举个例子: QString str = " lots\t of\nwhitespace\r\n "; str = str.trimmed(); // str == "lots\t of\nwhitespace"特此记录!
