Yes, I think that import/export buttons would be a good first project for me although I would want to take it further but one must learn to walk first.

I programmed in C++ from 1989 through 2004 then I switched over to more weakly-typed languages. I am completely unfamiliar with cross-platform development and tools. Is KStars "all C++ all the time"? or does it use a SpiderMonkey-like core where I can use C++ for CPU-intensive operations and JavaScript for user-interface programming?

Thanks.

It's completely C++, though we are using more of QML (similar to Javascript). But for now mostly C++.

Sorry for sending you this reply on the INDI forum. Yesterday, I signed up to join kstars-devel but I have not received the email confirmation yet. (I just finished sending an email to the webmaster to see if he/she could expedite.)

Have you heard of pluralsight.com ? It is an invaluable resource for learning new technologies. I found a 4.3 hour course called "Introduction to Qt: A C++ Cross Platform Application Framework" presented by Tod Gentille. Does that name ring a bell? It was released 29-May-2014; that is almost 3 years ago. Can you think of any major changes since then that I should be aware of?

Thanks.

Well, Qt is a huge world, but most of the principles are the same more or less. Found another one here www.udemy.com/qt-c-gui-tutorial-for-beginners/ for $10

I never received a reply from kstars-devel webmaster -- sad but true.

I've watched 3 online courses on Qt. It is very cool.

I am wondering though -- is it possible to write a Qt app in which C++ calls a JS function but the JS code is undefined at application build time? In other words I would like the user of the Qt app to choose a file from a dropdown list that contains the JS code. Once it is selected then the C++ code in the Qt app can call that JS function.

If that is not possible in Qt/QML, is it possible with D-Bus?

I don't think that's possible, but you can use D-Bus to call existing functions in KStars. kstars-devel is automatic reply, check your spam box.

Before discovering KStars, I was a C2A / OccultWatcher user. Today I returned to C2A and followed their directions to quickly compose my horizon in a single region file. I took what I learned and tried to do the same in KStars but unfortunately it will not properly handle a 360 degree horizon definition in a single region. So I broke it down into four quadrants and finally had success.


I would be interested to know exactly how you've achieved this please, as I would need something similar.
thanks


edit:
I think I got it figured it out, going to draw multiple regions to block off the part of the sky I cannot reach with the telescope.
