Why I dislike Qt signals/slots - elfery Why I dislike Qt signals/slots (Originally posted on Sunday, February 19th, 2012.) I've created over a dozen small projects using Qt by now. Most of the time I think I might as well make use of Qt's signals/slots system -- I mean it's already there. Using the Meta-Object Compiler (moc) | Qt 5.12 The Meta-Object Compiler, moc, is the program that handles Qt's C++ extensions. The moc tool reads a C++ header file. If it finds one or more class declarations that contain the Q_OBJECT macro, it produces a C++ source file containing the meta-object code for those classes. Among other things, meta-object code is required for the signals and slots mechanism, the run-time type information, and ... Multiple Inheritance Example | Qt UI Tools 5.12.3

signals, slots, Q_OBJECT, emit, SIGNAL, SLOT. Those are known as the Qt extension to C++. They are in fact simple macros, defined in qobjectdefs.h. #define signals public #define slots /* nothing */ That is right, signals and slots are simple functions: the compiler will handle them them like any other functions.
Qt's signals and slots mechanism ensures that if you connect a signal to a slot, the slot will be called with the signal's parameters at the right time. Signals and slots can take any number of arguments of any type. They are completely type safe. New Signal Slot Syntax - Qt Wiki Connecting in Qt 5. There are several ways to connect a signal in Qt 5. Old syntax. Qt 5 continues to support the old string-based syntax for connecting signals and slots defined in a QObject or any class that inherits from QObject (including QWidget) Q_SIGNALS / Q_SLOTS · Issue #644 · uncrustify/uncrustify ... If we use uncrustify 0.62 or 0.63 the following code will be changed. We expect the same indention of Q_SLOTS and Q_SIGNALS here. Looks like Q_SIGNALS and Q_SLOTS are not recognized as "slots:" and "signals:".
Qtのprivate slotsを隠蔽する - Qiita
Mar 13, 2016 · If I’m about to modify a slot function I might take an extra minute to look around since most IDEs can’t tell syntactically where it’s used in a SLOT() macro. In this case you have to search for it textually.) Thanks to C++11 lambdas and Qt’s ongoing evolution, these short slots can be replaced by a more succinct syntax. Qt in Education The Qt object model and the signal slot The QObject QObject is the base class to most Qt classes. Examples of exceptions are: Classes that need to be lightweight such as graphical primitives Data containers (QString, QList, QChar, etc)Classes that needs to be copyable, as QObject s cannot be copied New Signal Slot Syntax - Qt Wiki Connecting in Qt 5. There are several ways to connect a signal in Qt 5. Old syntax. Qt 5 continues to support the old string-based syntax for connecting signals and slots defined in a QObject or any class that inherits from QObject (including QWidget) . connect( sender, SIGNAL( valueChanged( QString, QString ) ), receiver, SLOT( updateValue( QString ) ) );

By making slot private you force users of the object to use connect function to call the slot, rather than member access operators(. or ->). c++ - Qt signals and slots: permissions - Stack Overflow
