What is the "right way" to signal specific instances of QML objects from C++?

Asked 2022-Jan-21 at 23:02

Right up-front, I'll apologize: This is a monster question, but I wanted to provide what I hope is all of the pertinent details.

I've got a QML-based GUI that I was tasked with taking over and developing from proof-of-concept to release. I believe the GUI is based on an example provided by QT (Automotive, maybe?). The GUI is being compiled for web-assembly (emscripten) and features a "back-end data-client" which communicates with our hardware controller via a socket and communicates with the GUI via signals. The GUI is accessed via web browser and communicates with the Data_Client via QWebSocket.

The GUI proof was initially created with a very "flat" hierarchy where every element is created and managed within a single ApplicationWindow object in a single "main" QML file. A Data_Client object is instantiated there and all the other visual elements are children (at various levels) of the ApplicationWindow:

I would go about this using Qt's model-view-controller (delegate) paradigm. That is, your C++ code should expose some list-like Q_PROPERTY of channel status objects, which in turn expose their own data as properties. This can be done using a QQmlListProperty, as demonstrated here.

However, if the list itself is controlled from C++ code -- that is, the QML code does not need to directly edit the model, but only control which ones are shown in the view and possibly modify existing elements -- then it can be something simpler like a QList of QObject-derived pointers. As long as you do emit a signal when changing the list, this should be fine:

How to connect slot with mutable argument to signal with const argument

Asked 2021-Sep-21 at 12:07

I need to connect binaryMessageReceived signal of QWebSocket to my slot which modifies the QByteData

The QByteData may be large so it might be really costly to copy it again in mutable variable each time. I want to reuse the existing QByteData

I think you could connect to lambda and use const_cast inside the lambda function:

Can't connect to Oat++ with other WebSocket libraries

Asked 2021-Jul-28 at 13:07

Does Oat++ support the RFC 6455 WebSocket protocol?

I tried to connect to an Oat++ WebSocket server from browsers by js, and from QWebSocket (qt), but they didn't connect.

To connect and test oat++ and other WS servers you may try using this online client:

https://www.websocket.org/echo.html - for WSS
http://www.websocket.org/echo.html - for WS

Also, make sure to connect to a correct endpoint

QUESTION

Do I need to use the Q_OBJECT macro if I only use slots?

Asked 2020-May-26 at 07:33

I have a few classes that are using QWebSocket and it seems I am able to call connect to handle callbacks for connect, close, etc. My debugger says that all is working properly.

If I use the Q_OBJECT macro in my class, than I have to run the MOC compiler in my cmake, which is a pain in the ass when trying to create a lib from my classes and use it in another application, that will make a separate post about.

If I delete the Q_OBJECT macro everything seems to build and run fine without it. So, question is, do I really need it if I am just connecting QWebSocket's signals up to slots?

A related post is: Using Qt macro Q_OBJECT for slots However, that is to tackle the error that results from not using the MOC compiler. I know how to do that, but I question whether I need Q_OBJECT in the first place.

From Qt QObject class reference:

Notice that the Q_OBJECT macro is mandatory for any object that implements signals, slots or properties.

The problem is that you are trying to send the text without verifying that the connection is successful. The solution is to use the connected signal, in addition to making m_webSocket a member of the class as advised in the comments:

QWebSocket Hello World Example

I am trying to use QWebSockets in a project. I wrote a small "Hello World" example to test how it will work. The problem: I can start the WebSocket server, but clients will not connect to it. My client goes into QAbstractSocket::ConnectingState but never really connects.

Answered 2020-Jan-24 at 16:56

You have 2 errors:

By not assigning the client object to a variable then it is immediately destroyed.
Qt needs an eventloop for the signals, events, etc. to work, in this case a QCoreApplication is enough.
