当你遇到“expression cannot be used as a function”这个错误时,通常意味着你在connect函数中错误地将一个表达式或变量当作函数来处理了。 解决方法 检查信号和槽的声明: 确保你连接的信号和槽在相应的类中已经正确声明。 信号和槽的声明应该使用SIGNALS和SLOTS宏(在Qt5及更高版本中,这些宏是可选的,但仍然推荐...

QT 判断 QByteArray某个字节的低8位是否是3 可以使用QByteArray的at()方法获取指定索引位置的字节,然后通过位运算来判断低8位是否为3。以下是示例代码: QByteArraybyteArray;// 假设这里是你的 QByteArray 对象 intindex=0;// 指定要判断的索引位置 if((byteArray.at(index)&0xFF)==3){ // 低8位是3 q...

Regexps are built up from expressions, quantifiers, and assertions. The simplest form of expression is simply a character, e.g.xor5. An expression can also be a set of characters. For example,[ABCD], will match anAor aBor aCor aD. As a shorthand we could write this as[A-D]. If ...
