Thread: QFileSystemWatcher send fileChanged() signal to a qml slot Let's continue the discussion about Qt signals and slots We can connect a signal to a slot in

As for connecting a QML slot to a C++ signal, I'll introduce that later in this book In order to demonstrate this, we need to create a C++ class in the first

casina slot SLOT(onButtonClicked)); return (); } As you can see, we get our qml button with findChild as before and we connect the signal to a Button

To invoke the C++ slot, a QML program can then simply call the respective function on the embedded object In order to receive the C++ signal,

qml signal slot qml), this); auto qmlObj = quickWidget->rootObject(); Connect QML signal to C++ slot connect(qmlObj, SIGNAL(qmlSignal), cppObj, SLOT(cppSlot(
