Welcome to A New Tutorial Blog!
First... some whining and rants :PComing from Borland Delphi (& Lazarus) and XCode experiences, learning Qt is something relatively new and uncomfortable. Tthe documentation is not newbie friendly. At all. And, there aren't many sites or blog that writes guide and code samples for complete newbies. They use simplified steps and missing out the crucial steps. Most tutorial sites speak non-newbie language. Even answers in forums are non-newbie-friendly.
Their answers are normally "find a book and read documentation yourself". This is totally opposite of what the XCode community is - who are mostly very generous in teaching others even down to the very basic of Objective C or Swift.
