slot no work in another class

[Aronax]

I haven't errors but when i build programm, debug write QObject::connect no such slots Myclass ::MyVoid().
what is it?
Thank's for answers!

[Zlatomir]

Show us some code

My guess is that you either made some mistake when called connect.
or is void MyVoid() declared as public slots: in the definition of Myclass?

[wysota]

Also make sure your class has the Q_OBJECT macro and qmake is called after adding it.

thanks for answers but I declared MyVoid as public slots and my class has the Q_Object macro and sorry that i don't show code because it on other computer and If you need I show code, please wait a moment..

QObject::connect no such slots CatalogViewImpl::createMenu();

[wysota]

So what is the exact message you get? With proper class names and all...

[Aronax]

when i do it in CatalogViewImpl class without created new class all works fine!
Exact message: QObject::connect: No such slot CatalogViewImpl::createMenu(const QPoint &);
QObject::connect: (receiver name: 'CatalogViewImpl')

[wysota]

What new class? You mean "Menu"? It has nothing to do with your original class so your original class doesn't contain slots defined in the Menu class.

[Archimedes]

createMenu(const QPoint &) belongs to class Menu and not to class CatalogViewImpl.
And you do this in CatalogViewImpl constructor:

connect (listEvHandler, SIGNAL(send_rightButtonClicked(const QPoint&)), this, SLOT(createMenu(const QPoint &)));

[Aronax]

As new class I keep in mind Menu class

Yes, but send_right ButtonClicked is separate class too but it's work..

Thanks for answers!! I understood my mistake!
