Delphi is a great RAD tool, but it's also slowly dying and has lower and lower market share, 100% of my income come from Delphi contracting at the moment, and I love Delphi, but its not a great choice if you're just starting your programming career and have to choose the language to go with. I've been sticking to Delphi for whole my programming career (3 years professionaly, 10+ years hobby programming, i'm 24 now), but its more and more occuring to me that I have to learn some new tech ASAP if I want to progress further. Delphi has no proper crossplatform support and it's a big minus. Also it has ridiculous price.
Was once in a similar situation myself. One path is to identify a future customer pain point that will occur if they continue to use Delphi. You can direct the solution to a language/platform you wish to learn, and work like a dog to develop the new skills and build a great piece of software in this new language.
Thats exactly my plan, to learn some basics then further improve skills on minor contracting jobs I get and I feel comfortable to do them in new language. It would probably be C++.
If you're looking at C++ already then I'd recommend Qt. I think it's pretty close to the RAD feeling I remember from C++ Builder and by extension I assume Delphi.
Compared to them it's not strong on data components that allow you to connect a DB to a UI, you will have to write SQL and code for that. But it is a joy to use, cross-platform and at least on the desktop it is free to use if you don't mind LGPL and shipping DLLs/so with your app.
I will certainly take a look at Qt, and other alternatives, but isn't Visual Studio the ultimate tool of all tools? I'd rather start with it from the start, since I'm already familiar with most of the programming paradigms and stuff that isnt tied to language itself, so it's just a matter of learning cpp + IDE, and I figured out I can easily enough start out with VS? Maybe it will have a bit slower learning curve than if i start with Qt, but at the end it will pay off.
Well, in all the C++ universe Visual Studio is a nice tool, but no one will hire anyone for knowing how to use it. It's the libraries and programming language skills that matter.
Qt is like VCL and it can be used within VS or without it. The Microsoft equivalent to VCL is MFC, but I don't think that's a very current skill to have. It's also the opposite of RAD, having to write lots of boilerplate to get something on the screen. I mean that's why MS invented .NET, MFC was unproductive.
The grandparent is a consultant, how many of this niche is hiring consultants? What are his chances of having steady (consulting) work using Qt? Let's be reasonable, he has a better chance learning MFC (not that that's a good idea either).
True, but since if one has a job working for an enterprise like that makes me want to kill myself in a hurry I consider that a feature, not a bug.
QT will get you into C/C++ programming, which will get you into backends, which will get you into much more pleasurable programming jobs. Yes, likely there'll be limited QT usage once you're there, but ...
