I have been developing Qt C++ application on Windows/Linux platforms about 3 and a half year so I know a bit about signal-slot and how to connect and disconnect them. QTimer Class Reference - University of Texas at Austin The QTimer class provides repetitive and single-shot timers. The QTimer class provides a high-level programming interface for timers. To use it, create a QTimer, connect its timeout() signal to the appropriate slots, and call start(). From then on it will emit the timeout() signal at constant intervals.

Passing a reference to a Qt signal is not dangerous thanks to the way signal/slot connections work: If the connection is direct, connected slots are directly called directly, e.g. when emit MySignal(my_string) returns all directly connected slots have been executed. If the the connection is queued, Qt creates a copy of the referencees. So when ...

Using C++11 Lambdas As Qt Slots – asmaloney.com 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.

Signals & Slots | Qt Core 5.12.3 Signals and slots are loosely coupled: A class which emits a signal neither knows nor cares which slots receive the signal. 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. c++ - Undefined reference to signal in QT - Stack Overflow 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.
