Why do many enterprise software companies offer free (or low cost) trials then? Does the company that you work for (or yours if you're a founder) take the same "take it or leave it" attitude towards potential customers?

No, they don't. Not in any meaningful sense. They're offering to let you evaluate a bed, so long as your evaluation doesn't include sleeping on it.

Excuse me, but who here has said a single thing about the customer dictating terms? Not a single person.

The question was rhetorical, thanks.

No one is asking for either a hand-out or freebie. Potential Customers are asking to evaluate a product before paying for licenses THAT THEY MIGHT NOT USE. That is not un-reasonable.

There are still some cases where you need a license, like Qt for Device Creation ( https://www.qt.io/qt-for-device-creation ). Or perhaps you need static linking, or want to include some Qt code in the app proper for one reason or another.

Ok, but if you stick with dynamic linking and don't insert Qt code into your app, then you don't need a commercial license, right? Why would you insert Qt code in your app anyway? That kinda defeats the point of using a library. As for static linking, why would you opt for this over dynamic linking anyway? Dynamic linking is better since other applications can share the libraries. Static linking on a PC platform is b…

Just listing some possibilities, different projects have different needs. Sure, for most of the cases the dynamically linked open source version works just fine.

Qt for Device Creation needs a license, that one is not available as LGPL. Of course you can use the open source Qt yourself for that, but then you'll be facing a lot of platform work to get Qt running on your device before even starting with the stuff that you actually want to build.

You are correct. The only serious frameworks nowadays are Qt or Electron if you're targeting the cross-platform desktop. There's also wxwidgets, although its python 3 bindings are still being built. Personally, I'm keeping my eye open on libui ( https://github.com/andlabs/libui/ ) as it is already possible to do some basic things with it. However, it is pretty much in alpha state and I'm slowly writing the Python bin…

"Regarding Electron, I am writing an application on it, but it is too god damn heavy in terms of memory, disk space and boot time," Try Sciter HTML/CSS engine then ( http://sciter.com ). It is a monolitic DLL (4-8 Mb) without external dependencies. Works on Win/Lin/OSX and even on Raspberry Pi 2 - http://sciter.com/sciter-on-raspberry-pi-2/

Thanks for the suggestion, I didn't knew about this before! So I've tried it, the lib is small (~9MB on OS X), it renders pretty fast and has python bindings which is quite great.

However it lacks in some areas, such as the scrolling which is quite bad, and it does not render the SVG files that I'd need it to render (tiny SVG spec, but lots of defs and rotations). I'm still going to look better into it since I can use Cairo and CairoSVG to convert my SVGs to PNGs, but I still do not know how well it renders some css rules, fonts, etc..

That would be why there's a 30 day free trial, for potential customers to evaluate with: https://www.qt.io/download/#Licence-anchor
