A Qt QML Beginner’s Project: MotoRing, part 2 – Rewind and Reveal

Finally, here’s the much-demanded second part to this QML beginner-focused series.  Okay, one guy asked, but he sounded really interested.

I said at the end of the first article that I would progress to the next phase in this one.  But the request for a screenshot of the app at this point got me to thinking that it would be worth more to fledgling QML developers if I backed up and broke down the code.  So let’s do it.  There’s a lot to cover, so I’ll spread it across two or three articles.

A Qt QML Beginner’s Project: MotoRing, part 1 – GPS

I unloaded some Qt newbie frustration the other day detailing my first serious efforts to code for the Nokia N9.  Now I’d like to step back a bit and outline the actual project, and in subsequent posts walk other newcomers through my coding journey of pleasure and pain.

First a disclaimer: I’ve been programming for over 25 years.  That has included COBOL, Forth, Logo, DOS/VAX/Unix batch commands, Basic, LISP, Pascal, C, JavaScript and Visual Basic (both COM and .NET).  While I could work minor wonders with scripting and compiled linear languages, I found that I have been most productive in event-driven VB.Net.  Readers should know that I am not targeting an audience that’s totally new to programming, but rather, programmers who like me are experienced with other languages and platforms but new to Qt.

I really wasn’t very apprehensive about Qt, especially the mature 4.7.  Friends kept telling me how easy it was, and the Qt Creator environment did not look difficult at all at first glance.  Continue reading

Why I am Every Qt Expert’s Worst Nightmare

As I’ve noted before, I have been interested in Qt development for some time and finally got to where I could allocate the hours to learning.  I missed out on local Qt training a while back so I’m dependent on documentation along with patient people online.

The latter have been a huge help.  I’ve encountered some weird and frustrating situations from which many friends have rescued me.  The former, however, have been severely lacking.  But let me share the pain with you progressively.

I decided to create an application for the Nokia N9.  The app will make use of GPS and cellular services mainly, and shouldn’t be very complicated.  I chose Qt Quick because I wanted to see how mature QML really is at this point.  Plus I’m allergic to C++.  Continue reading
