Error to declare signal

[sakya]

Signals don't have code.

This code is wrong:

void bancoDados::conectar()
{
    bool retorno = true;
 
    emit retorno;
}

void bancoDados::conectar()
{
    bool retorno = true;

    emit retorno;
}

To copy to clipboard, switch view to plain text mode 

To emit a signal you just need to declare it (with arguments if needed):

signals:
    void conectar();

signals:
    void conectar();

To copy to clipboard, switch view to plain text mode 

And then emit it when needed:

emit conectar();

emit conectar();

To copy to clipboard, switch view to plain text mode 

If you need to pass that boolean value to the signal you declare it and pass the boolean as argument:

signals:
    void conectar(bool);

signals:
    void conectar(bool);

To copy to clipboard, switch view to plain text mode 

emit conectar(true);

emit conectar(true);

To copy to clipboard, switch view to plain text mode
