@DiBosco I do not know whether to count as "C++" it depends on (a) flags you pass to compiler or (b) content is C++ or maybe even file extension. What I believe I do know is if it is C++, by whatever reckoning, you cannot mix MinGW C++ code/modules/objects/libs with MSVC. So if you continue this way one side or the other of your MSVC/MinGW will have to be limited to C in order to link them. Which might suffice for some purpose of yours, but not if they are each proper C++ projects. And you won't be able to mix them if they both want to call any Qt stuff. A lot of basic libraries supplied with Windows are C only. Although not sure, I think this may apply to the whole of Windows, certainly the "Windows SDK" stuff. That can be used. As can, importantly, the runtime libraries named something like MSVCRT.DLL/LIB which give basic start up, memory management and that sort of thing. MinGW does use these from MS/MSVC, I believe. Because they are all C only. As for whether things provide only one compiled version, as you suggested, or multiple compiled versions. Well, like I say I cannot check, but I assume that Qt itself, if you fetch pre-compiled for Windows (as I believe you can), will supply a completely separate set of its Qt/C++ DLLs in a download for MinGW versus for MSVC? So they are supplied differently, if I am correct. I would have thought you should pick one of MinGW or MSVC, and one of Creator or VS, and stick to that for all your work.

I am QML side, I do not remember the last time I used QWidgets. I would say I can do whatever I want/think with QML. It is a shame people still do not understand how one can produce cross-platform reusable GUI components with the mix of CMake, C++, and QML. The latter components can be plug and play in your application. Also, QML is a declarative language that makes it cleaner than C++ for UI interfaces. Now with tools like qmllint, it is quite easy to find errors before they happen at runtime. QWidgets is C, and QML is C++ in the sense that if you want a fast thing done, you use QWidgets; if you want to design a reusable, nice-to-use interface, you use QML.

In QDS, SVGs usually look blurry when the path is being scaled instead of rendered at its native size. Make sure the SvgPathItem matches the original SVG viewBox and avoid scaling it down inside the component. If possible, import the SVG as a file and use an SVG Image element rather than pasted path data, and keep width/height proportional to the source. This prevents QDS from rasterizing it at a low resolution.

Found it. I overlooked the following traceback in the logs. Traceback (most recent call last): File "/mnt/ssd2/develop/experiments/python-squish/mysquishtest.py", line 16, in <module> squishtest.waitForApplicationLaunch() RuntimeError: Waiting for application timed out When I remove the call squishtest.waitForApplicationLaunch() it works and I can use squishtest.test.compare() to test conditions.

Hi everyone, We work on developing enterprise learning and training platforms, and recently we’ve been exploring Qt for building desktop or device-based applications that support safety training use cases. In industries like oil & gas—especially in regions such as the UAE—safety training systems often need to support offline access, structured learning modules, controlled user roles, and reliable performance across different environments. We’re interested in understanding from the community: Has anyone used Qt for building training, compliance, or safety-related applications? How well does Qt scale for enterprise-focused learning or content-driven platforms? Any best practices or architectural considerations when using Qt for regulated industry use cases? This is mainly an experience-sharing and learning discussion. Looking forward to hearing your insights. Thanks!

Sometimes, like when you are marooned on a desert island [in an announcer voice] Coming soon, to a desert island near you... :) Yeah, I guess cases where all you have is text search on a big code base are not that uncommon, like when browsing github repo or something like that, but specifically overrides... I don't think I ever had to look for overrides this way. Oh well, different people different use cases.
