Waiting for qt signal in c++ function

[NewbieQTUser]

Hi,
im search way to recive signal from qt object in c++

fnx(){
QSharedPointer client; //pointer to qt object
client->doSomeWork(); //its emit done when finished.
...
next operations.
}

@NewbieQTUser You can also connect a function:

void fnx()
{
    client->doSomeWork();
    QObject::connect(client, &ClientClass::done, &doStuff);
}

void doStuff()
{
    // following operations
}

Hi,

Why not connect that signal to a function that will continue the processing ?

[Chris Kawa]

void MyClass::fnx()
{
    client->doSomeWork();
    connect(client, &ClientClass::done, this, &MyClass::doStuff);
}

void MyClass::doStuff()
{
    // following operations
}

Im calling it from generic c++ app, i cant use connect syntax

[Chris Kawa]

@NewbieQTUser What do you mean you can't? If client emits a signal it means it's a QObject. If you're accessing QObjects you can access connect. Qt is generic C++, so could you explain what's your problem exactly?

connect is a static method so you still can.

Otherwise, you can pass that method to your doSomeWork function so that it can be connected to by your class.

Its function only, but i will try pass it to doSomeWork, thanks for help :)

@NewbieQTUser You can also connect a function:

void fnx()
{
    client->doSomeWork();
    QObject::connect(client, &ClientClass::done, &doStuff);
}

void doStuff()
{
    // following operations
}

Also thx, looks like a good solution
