Signal from QML to C++ and threads
I have a login screen in QML. When the user clicks "Login" a signal is emitted, which is processed in a C++ object. The C++ objects does the login, which is a time consuming operation.
Now my question: Should the C++ object start a separate thread for this? If the signal-processing function (the slot) takes time, will it block the UI (or other stuff) and is it already in a separate thread?
If UI is first thread and signal-processing function is second thread, then second thread should not block the first thread.
But everything depends on the implementation of
That makes sense.
But is the implementation consistent across platforms and Qt versions?
