    Default QT5 connect server.cpp and window.cpp

    Hello i am new to C++ and QT5.

    I have build a application for displaying data, which are received via a server.

    I would like to update the displayed data when the server reads a new file. I have successfully build a refresh via a button click and the connection to the client and the transmitting of the data is fully functional, but how can i connect the server (done()) with the window resetGrid()?
    I tried something like

    QObject::connect(server,SIGNAL(done()),window,SLOT (resetGrid()));

    but it does not work

    edit:
    silly me.... just had to use references
    -> QObject::connect(&server,SIGNAL(done()),&window,SL OT(resetGrid()));

    Problem solved, just had to waste 4 hours for this :/

    No, you had to use pointers, not references.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.
