Is the support for static linking good in JUCE, such that you can release non trivial programs in a single binary with reliance only on system libraries that are pretty much guaranteed to be there.

Yes. I only use JUCE on OS X and Windows, but it's all statically linked and looks like it should be on other platforms. On windows you can change the linker settings from /MD to /MT so you aren't even depending on the MSVC redistributables that a completely bare system might not have.

Great! It's nice to be able to easily build and distribute a single executable. Many users are barred from installing software; but can grab single file and run it.

I really like Qt and think its an incredible framework overall. Even if you don't use the Qt libraries, QtCreator is one of the best C++ IDEs out there imo (though qmake really sucks and they've been dragging their feet on a proper replacement for years)

The real show stopper for me with Qt is its licensing though. LGPL is a no-go on closed mobile platforms and its commercial license at $350/month is completely unreasonable for smaller developers. Really, the LGPL is a horrible license because of its clause that you must be able to change out the LGPL portion of the software.

Also almost every time there's a thread about Qt I see a bunch of (presumably) web developers start talking about React. In fact, in pretty much every thread talking about any similar framework someone has to mention React. I'm not a web developer and I've only looked at React briefly but I guess I just don't get it. Could someone explain succinctly what the big deal is? I've used Qt a lot -- what do all these people mentioning React want Qt to offer? Why is it brought up so often? Is it really that revolutionary? Almost seems like a cult.

Qt is easily the best cross-platform UI kit that I have used, especially in combination with Python, which turns it into THE rapid prototyping tool. For my research I used PyQt/PySide to build lots of UI components for controlling my lab equipment, visualizing my data and running code in an interactive way. While doing this kind of thing using a native toolkit (MFC, GTK) would have been possible, it would probably ha…

" While doing this kind of thing using a native toolkit (MFC, GTK) would have been possible, it would probably have been much difficult and time-consuming."

With Lazarus and FreePascal you could do that in minutes.

Will it be worth it/extremely hard to learn C++ just to use Qt? (I always read here and reddit about how hard/inefficient/easy to fail is everything is in C++) (Eng. background and software dev full time)

If you just want to use Qt, I recommend PyQt / Python. But there are worse ways to learn C++ than via Qt, if learning C++ is your goal.

Can I use the new fancy compiler stuff like Lambdas with QT? Does it still require a meta compiler?

Lambdas can be used e.g. with the new signal-slot syntax [1]. And yes, Qt uses the meta compiler, and it's hopefully going to stay that way as moc has a clear positive impact both on features and speed [2]. [1] https://wiki.qt.io/New_Signal_Slot_Syntax [2] https://woboq.com/blog/moc-myths.html

Wow I had no idea you could put lambdas in place of slots!! Thanks!!

My problem with Qt is that it seems like only Python has language bindings that are good long term bet for a project. I'd like to see bindings for Go, Rust, Node.js, and C#/.NET Core with dependable long term commitment to quality. I think there's more a business case to do these than there ever were for Qt Jambi(Swing and SWT existed) or PySide(basically, duplicating PyQt because it's GPL not LGPL).

Here are non-qml bindings for Go. IT actual qorks quite well. https://github.com/visualfc/goqt

Is Qt still a good platform for new desktop apps? I often have to choose a framework for new line of business apps on Windows. The choice usually is WPF but I'd prefer Qt. Last time I looked into it it looked a really well thought out framework. And I am one of the weird people who prefer C++ over C#. My only concern is availability of 3rd part components like data grids, reporting and other widgets. There are many o…

You can use Qt Charts or Qt 3d. Here is a link to the charts docs

As someone who have spent the last six months learning C++ (making the transition from web developer) all I can say is that it'll be hard for me to leave Qt framework. It's very pleasant to work with it (although some corner cases can give you headaches). I'm mostly working with Qt Quick/QML in general (previously I used the widgets but I needed "easy access" to more eye candy effects without spending too much time i…

> As someone who have spent the last six months learning C++ (making the transition from web developer) Any particular reason why? I know a lot of people doing the opposite (because there are so many more web dev gigs out there).

I want to expand my knowledge. I'm almost done with college and I'm both thrilled and terrified on what will I encounter from here on, there is still a lot to learn.

I'm not as good as many people here I just lurk most of the time, although, I've been doing web development for years, mostly self-taught. I had the opportunity to freelance as well.

Most of my drive to learn C++ is curiosity and the need to be able to write/understand C++ code because I wanted to work with it, I've been meaning to get an Arduino kit too. I'd love to enter the field in C++ as junior dev if possible, at the same time I won't neglect web development if the opportunity is there.

As I said before, I want to expand. I won't just "throw away" web development either. Lastly, I'm not in the US, the job market here is pretty terrible, and have found it hard to look for a place to work. I can work in the U.S, but sadly being both college student + no cash to do much it's pretty hard to pull off.
