Qt signal slot template class

Qt for Beginners - Qt Wiki Most of classes in Qt inherit from this class. QObject provides some very powerful capabilities like: object name : you can set a name, as a string, to an object and search for objects by names. parenting system (described in the following section) signals and slots (described in the next chapter) event management

I would like to create something like adapter for slots, which would do something, but the slot can take arbitrary number of arguments (number of arguments depends on the template argument).

C++ Qt Template Class Signals/Slots - Stack Overflow So I'd like to make a template class in C++ Qt. The problem is that I'm using signals/slots in this class. My class header looks like template class Container : public QObject { c++ - Qt signals and slots in different classes - Stack Overflow

SignalsandSlots in C++ SarahThompson∗ March2002 1 Introduction This paper introduces the sigslot library, which implements a type-safe, thread-safe signal/slot mech-anism in C++. The library is implemented entirely in C++, and does not require source code to be pre-processed1 in order for itto be used.

function to relate the signal to the slot. Qt's signals and slots mechanism does not require classes to have knowledge of each other, which makes it much easier to develop highly reusable classes. Since signals and slots are type-safe, type errors are reported as warnings and do not cause crashes to occur. For example, if a Quit button's Qt Tutorials For Beginners – Qt Signal and slots May 30, 2016 · In this tutorial we will learn How to use signal and slots in qt.

In the function FunctionPointer::call, the args[0] is meant to receive the return value of the slot. If the signal returns a value, it ...

Qt не позволяет мне использовать шаблоны в большинстве своих классов, поскольку компилятор MOC (или лучший препроцессор) запускается до того, как произойдет генерация кода c ++. Существует ли разумная альтернатива концепции внутреннего Sing/ Slot Qt?

Qt: How to implement common base-class signal/slot Sometimes when inheritance is problematic, one can replace it, or a part of it, with composition. That's the approach needed in Qt 4: instead of deriving from a QObject, derive from a non-QObject class (MyObjectShared) that carries a helper QObject that is used as a proxy to connect the signal to its slot; the helper forwards that call to the non-QObject class. Template class not supported by Q_OBJECT | Qt Forum Ok, having base class with non template signal-slot functionality and to derive a template class from it, will work fine for me. but, just for knowledge, what if i need to have signal-slot with template type.???
