I am using QtCreator. The thing I find odd is that when I type

Sender.

Sender.

To copy to clipboard, switch view to plain text mode 

it shows a list of the members of that class and that list "contains" sendData function.

What point am I missing? Yes, sendData has been defined in the corresponding .cpp file.
