I don't remember adding these non-standard paths in that previous project
Before, your header files and source files were located in the same directory. The preprocessor searches for header files in same directory, then in directories specified using -I parameter (that is what INCLUDEPATH adds) and then in system directories.
@aha_1980 Thanks for the answer . I will try your sugestions and see how it goes. I've done all this text to ASCII in console codeblocks C++ but it seems that i need a gui to it. I am not as good in Class'es and things like that. I will try it anyways. An example could be more than good for one letter . i could do the rest alone :P . Have a good night
Thanks for the quick answer. Now I understand I didn't asked my question correctly.
I know it is possible to do this, but I actually want to combine a qml into my .ui widget.
I finally found a tutorial for this (https://www.ics.com/blog/combining-qt-widgets-and-qml-qwidgetcreatewindowcontainer). It says it is only possible to do this from qt 5.0. For my embedded system I'm working with 4.7. So this isn't possible for me.
