How to Access a C++ Object from QML. Before we go into any details, let us start by creating a simple Felgo Apps project with Qt Creator. If you are new to Felgo and don’t know how, please consider having a look at the Getting Started Tutorial or the Felgo Designer Tutorial Video.

qt and slots - private/public qt signals - CODE Q&A Solved Slots are simple methods which can be public, protected, or private. As Andrei pointed it out, signal are only a redefinition of protected, meaning they can only be emitted by the class in which they are defined. QThreads general usage - Qt Wiki We add at least one public slot which will be used to trigger the instance and make it start processing data once the thread has started.

You can use parameters and return values to pass data to and from C++. 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.
I always use private slots when setting up internal connection within the same class and public otherwise.... but I never actually thought to check (or to notice) that Qt does not inhibit visibility of the private slot! - still, this won't change the way I define them because even if Qt is lenient (or just wrong here) I don't like to be
