Most likely, the Q_OBJECT macro ad signals: declaration in A.

Re: [Interest] Qt basics - QObject::connect: signal not found

Konstantin,

It is supposed to be the same thing. 

I don’t know what happened but I have moved the signals declaration below in 
the header and now is working. 

It’s working now! I hate when I don’t know exactly what has made the 
difference..

Thanks anyway! 

Regards,

Nuno

I'm sorry I was left with the impression we are talking about C++, I have
no experience with the language you use (I imagine that's Objective-C).

Re: [Interest] Qt basics - QObject::connect: signal not found

Konstantin,

There isn’t much more, really! 

DRCController is B
IController is A

This is the function where the connect is called (in a Cocoa file)

- (void)openWithAu:(AudioUnit)inAU andController:(IController*)controller
{
_controller = controller;

_controller->connect(_controller, ::grabFocus, [=]() {

});
}

And the error is:

QObject::connect: signal not found in DRCController

That’s it! Nothing more! :(

Regards,

Nuno

You don't need to cast `B *` to `A *`, B is already A and is casted
implicitly (and safely) by the compiler.

I’m getting "signal not found in B” error

Could you attach the whole error (the one from the failed assertion), it

[Interest] Qt basics - QObject::connect: signal not found

2017-11-06 Thread Nuno Santos 
Hi,

I have a class B that extends A.

I’m passing a pointer of B casted to A to another C, and inside C I call:

connect(BPointerCastedToA, ::signal, [=]() { // do something });

I’m getting "signal not found in B” error

I have similar situations in which this scenario works (B extends A and I 
connect B to signals of A). I can’t understand why is not working. 

What am I missing? 

Thanks!

Regards,

Nuno
