[Solved] Problem with signal/slot carrying pointer - qt -… QT. I`m facing an error while connecting a signal to a slot in my project, it is:

A slot is a function that is called in response to a particular signal. Qt's widgets have many pre-defined slots, but it is common practice to subclass widgets and add your own slots so that you can handle the signals that you are interested in.

Qt libraries work using the mechanism called signal-slot. Basically this is a optimal way to make an asynchronous communication between objects in any kind of conditions and transmitting any kind of data. However, sometimes, may happen the need to wait for a very short time event (for example wait for the end of a short animation).  CSCI 104 Qt Intro - USC Viterbi • Knee defines a slot function –A slot function must match the prototype of the signal function that it will be connected to –You can do whatever you want in this function • You must connect signals to slots via connect() –See reflex.cpp • You can have multiple slot functions connected to 1 signal  Embedded Developers World: Qt/QML interview Questions Qt/QML interview Questions Q)what is Qt ? Qt is a cross-platform application framework that is widely used for developing application software that can be run on various software and hardware platforms with little or no change in the code.  Frequently asked questions in Qt interviews - C Linux Code ... In most circumstances, when a "signal" is emitted, any slot function connected to it is called directly. The exception is when signals and slots cross thread boundaries. In this case, the signal will essentially be converted into an event.
