qt signature is not normalized. 1. 解释什么是QT签名未归一化 在Qt框架中,信号(Signals)和槽(Slots)的连接是通过元对象系统(Meta-Object System)实现的。这个系统使用了一种基于字符串的签名来识别信号和槽。然而,这些字符串签名在连接时需要被归一化,以确保它们能够以一致的方式被识别和匹配。如果信号或槽的签...
connect(g_pSplitterMain.get(), SIGNAL(splitterMoved(int, int)), this, SLOT(slotSplitterMoved(int, int))); 上面代码编译时警告:mainwindow.cpp:218:36: Signature is not normalized. Use splitterMoved(int,int) instead of splitterMoved(int, int) [clazy-connect-not-normalized] 在你的代码中,提示...
tmp_signal_name = QMetaObject::normalizedSignature(signal - 1); signal = tmp_signal_name.constData() + 1; //重新进行签名转换,并得到参数类型列表 signalTypes.clear(); signalName = QMetaObjectPrivate::decodeMethodSignature(signal, signalTypes); smeta = sender->metaObject(); signal_index = QMet...

if (signal_index < 0) { //相对序号为负数,则表示没找到,则规范信号名(去除空格) // check for normalized signatures tmp_signal_name = QMetaObject::normalizedSignature(signal - 1); signal = tmp_signal_name.constData() + 1; signalTypes.clear(); ...
() == 48 return 0; } SIGNAL和SLOT宏将括号中的内容封装成一个字符串,同时还附加一个ID号,如下所示: #define SLOT(a) 1#a #define SIGNAL(a) 2#a 所以,也可以直接这么写connect函数: QObject::connect(a, 2valueChanged(int), b, 1setValue(int)); signals和slots是Qt关键词,可以在头文件中...
SIGNAL()和SLOT()宏; connect 方法; 触发信号; 3.1、Qt的元数据系统 没看过Qt源码的同学可能会对QMetaObject有些陌生,我们打开Qt手册,查看此类的说明,介绍如下: The QMetaObject class contains meta-information about Qt objects.The Qt Meta-Object System in Qt is responsible for the signals and slots int...
