[Qt-creator] How to put individual classes to sub dir

Tue Aug 24 15:01:36 CEST 2010

Hi Jakov,

I think Adam already told you all you need. Thank you, Adam!
Have Animal.pro, which includes Dog.pri and Cat.pri. There, list the
respective headers and sources.

For further reference have a look at:
http://doc.qt.nokia.com/4.6/qmake-manual.html

Regards,
Robert

The second way, Animal has 3 nodes: Forms, Headers, and Sources. Corresponding type of each class (form of Dog, form of Cat; header of Dog, header of Cat, etc) would be included in those nodes. This way seems intricate, complicated,... and not what the user expected.
