Unsolved How to use QWebSocket, QTcpSocket globally across the application?
-
I need to send packets from other classes, should I register a slot in my QTcpSocket class like "send" connect it and emit from other classes? Or is there a better way? Can I just use singleton like:
QTcpSocket g_tcpSocket;
-
Usually you'd create a custom class like
MyNetworkHandler
that then can be a singleton if you wish. That class with have the corresponding methods to send the data you need to send from the different parts of the application.Of course there are other solutions as well - it really depends on your needs and the design of the existing parts of the application. The above is just a good, common approach (in my opinion).

@Joel-Bodenmann
MyNetworkHandler
containingQTcpSocket
member? Does it mean I can directly call it without using signals? -
It really depends on your needs. Theoretically you can make
MyNetworkHandler
become a subclass ofQTcpSocket
and just make it a singleton. If you need more flexibility thenMyNetworkHandler
can just have aQTcpSocket
instance as a private handler. In that case you can still add your own signals and slots and/or forward those fromQTcpSocket
where applicable.
