Introduction to Qt

Interested in expanding your C++ code to have an amazing
User Interface that can be run on Linux, Windows and Mac?
Well, Jeff Alstadt will give you an introduction to the Qt
framework which allows you to code less and be more
productive.  Qt is 20-year-old UI framework that is designed
with C++.  The presentation will include an introduction to
the Qt Event System, Qt Signals and Slots concept, and a
demo of building a simple Qt application.

Prior to the main event, the Axiom Group (,formerly known as WWFIRS, will be providing a pizza dinner.

In addition to the technical presentation, we shall be
giving away more than 300 dollars' worth of C++ books,
all published in 2012 or 2013, donated to our group by
publishers hoping to encourage sales by giving away free
samples of their product.

We shall also need to approve formally the proposed by-laws
for our organization (if you haven't yet voted, please do
so now -- click More -> Polls on the home page menu).

About our speaker:

Jeff is a Software Engineer at Litholink/LabCorp.  He is
passionate about everything that is cross-platform from
mobile to desktop to web applications.  He is also active in
the developer community: Jeff co-founded the Software
Development Community Meetup which has around 700 members
from the Chicago area, and also founded Qt Chicago which is
a meetup dedicated to the Qt framework.  Jeff actively blogs
about his coding adventures on his website at and can be reached at jalstadt @

    I think that we (especially Jung) are being too harsh with Jeff, presenting is not an easy task, and, now he has some feedback of how to proceed if/when he wishes to present another topic: * Time is of the essence to people
    * It would be very helpful to go home with code for a minimal
    "hello world" app.

    In the past, I've used Pavel Holoborodko's instructions, to build a Qt App on Windows using the instructions located here:

    I hope some of you find this useful.

    (I'm sure one can also download it onto other platforms, but I haven't done this).

    Jung's latest comments are well thought out. My only disagreement is that in extremely bad weather it's customary to delay the start a few extra minutes. The Chicago Symphony Orchestra does that with 2500 paid seats, so it's reasonable for us.

    We need to be more respectful of people's time.

      I've been to one other meetup and it was better.

      I'll chime in--with a title like "Introduction to Qt" I too expected a certain kind of talk. With the best presentations of this type, a person who comes in clueless walks out with some working code however trivial. This is the great advantage of a compressed talk over any book. With open source, you could even ask people to install something on their laptop before the talk--I would do it.

      I am interested in other kinds of meets/talks as well. But "intro" in my opinion should not veer into marketing, porting to bizarre platforms (I don't mean the very pertinent point about Mesa/OpenGL--you know what I do mean), or even details of IDEs or the best way to lay out a project. A working hello world trumps all of these.

      That said, I sympathize somewhat with the presenter. Derailing questions have their peculiar lure, especially if you are the polite type ...

    The meetup site states that "62 attended"! Attendance was actually only about half that number. But we had no check-in procedure, so there's no way to record who was and who wasn't there.

    Missed the event this evening due to bad weather. Is there any presentation material available for downloading?

    February 26, 2013

    • Jeff A.

      Kevin I will send it out

      Kevin (and anyone else who wants to know): Jeff e-mailed me a .pptx file a few minutes ago, and I have put it on the ccug website from which you can retrieve it at http://ccug.chicago.i...­. Your download speed will be limited by the speed of residential DSL, so if anyone here wants to copy it to a faster server, and tell us where you put it, go right ahead.

    I generally agree with Jung's comments below. I have e-mailed Jay and Jeff with my concerns. Hopefully the next meeting will be better.

    Things I liked:
    The raffle idea was pretty awesome, and pizza is always nice. Having the recruiters was neat, as it could be a good lead for those looking for a job. Things that could use some work:
    >2 hours is <em>a lot</em> for an after-work event. It would help if future events were shorter and had a specified end time. This way, people that have long commutes/want to put their kids to bed/have to take out the trash/etc. know what to expect. Of course, those that wanted to stay longer, could. My personal preference is <1.5hrs (with presentations being <= 1hr), and the option to stick around for socializing. It'd be the responsibility of whoever is organizing that night to ensure things stay timely.

    Saw the forecast for tomorrow, may be pulling out if it does snow as I'm coming in from Mt. Prospect and heading back after the meetup.

    I'm excited to see you all in my office next week! Lauren - I'd think you;d have to ask Jay but I don't think he'd mind. Obviously, I'd love to help as well

    Qt is an amazingly cool platform, especially since going LGPL. Hope to make it.

I started the group because there wasn't any other type of group like this. I've met some great folks in the group who have become close friends and have also met some amazing business owners.
