I actually do use the "F1" -key very often inside Qt Creator and really try to find the answers first from docs before asking here

Problem (for me) is that most of the docs are written in the way that the writer assumes that reader already knows how things are working and therefore they are lacking the basic guides like:
1. create QFile "object" or what ever it's called
2. you must open the file with separate command so type file.open
3. do something with the file you just opened
etc etc....

But I'm slowly learning and thanks to you guys for answering my questions over and over gain.
