Hybrid script/C++: A script can connect signals and slots to establish connections between pre-defined objects that the application exposes to the scripting environment. In this scenario, the slots themselves are still written in C++, but the definition of the connections is fully dynamic (script-...
You’ll also be taken through advanced concepts such as asynchronous programming, event handling using signals and slots, network programming, and other aspects to optimize your application. By the end of this Qt book, you’ll have the confidence you need to design and customize GUI applications...
The REVISION tag is used to mark therootproperty as added in revision 1 of the class. Methods such asQ_INVOKABLE's, signals and slots can also be tagged for a revision using theQ_REVISION(x)macro: classCppElement :publicBaseObject { Q_OBJECT Q_PROPERTY(introot READ root WRITE setRoot N...
You will also learn advanced concepts about signals and slots. Finally, the book takes you through debugging and testing your app with Qt Creator IDE. By the end of this book, you'll be able to build cross-platform applications with a modern GUI along with the speed and power of native ...

The Felgo SDK and Qt have many QML components available. For a starting point to integrate Qt C++ or make native features available for QML, you can see the guide How to Expose a Qt C++ Class with Signals and Slots to QML.QML MVC: App Architecture Best Practices and Design Patterns...
Connecting Signals and Slots Qt provides the signals and slots mechanism for communicating between widgets. Signals are emitted by widgets when particular events occur. We can connect signals to slots, either pre-defined slots or those we create ourselves. In older toolkits this communication would ...
QFutureWatcher allows monitoring a QFuture using signals-and-slots. QFutureSynchronizer is a convenience class that automatically synchronizes several QFutures.Qt Concurrent supports several STL-compatible container and iterator types, but works best with Qt containers that have random-access iterators, ...
For a full example, see the section “Another Example for Signals and Slots” in Chapter 2. Dials Dials (see Figure 4-8) are very similar to sliders. They are a recent addition to Qt, and most people could probably just get along with using sliders exclusively. There are two differences...
