#endif 在Debug版程序中,Q_ASSERT会调用qt_assert函数,而在Release版程序中,便会调用qt_noop()函数, 再看看qt_noop()是什么: inlinevoid qt_noop(void) {} qt_noop就是一个内联空函数,在Release版中将被优化掉。 将刚才的程序代码改成: Q_ASSERT(c == 7); 并再次调试运行,程序便不会被断下了,因为表...

3 二者对比 这两个宏都是在我们传入的值为false的时候触发,都会打印信息,只是Q_ASSERT_X支持打印我们自定义的信息。 4 特别注意 不论是Q_ASSERT也好Q_ASSERT_X也罢,都是在Debug才生效的,在Release版本中,将被自动优化掉如下图所所示 4 参考链接 ...
在QT_NO_DEBUG 模式下,也就是调试模式下程序会执行qt_assert(),在 Release 模式下执行qt_noop()函数,而 qt_noop()函数是一个内联空函数,什么都不做,定义如下: inline void qt_noop(void) {} 1. 建议大家在程序中多使用断言来进行判断逻辑,有助于尽早的发现并解决程序中隐藏的错误点。
