Language Bindings

Hi,

I am unearthing quite an old topic, but I recently re-discovered pyqtdeploy and it seems to be fairly relevant these days: cross-compilation with Python is a hot topic.

Although there is documentation online about pyqtdeploy, it is hard to figure out specific steps to set up the tool.

I have decided to update the documentation and upgrade a bit the tool on my side first.

If you wish to convert your PyQt5 apps into Android apps, follow the in-depth tutorial on https://github.com/achille-martin/pyqt-crom.

There is no official support for PyQt6 in my repo yet though. So please start with PyQt5 to build prototypes and I am expected to add support for PyQt6 later.

@JonB thanks for your reply.
I found a similar topic on stackoverflow.
That helped to solve my problem.

@Sachin-Bhatt
The intention is that Qt SQL interfaces handle most if not all of SQL data types, and deal with SQLite correctly, so that you don't have to do what you say. I think you should give a couple of examples of data types where you have "data type compatibility concerns" and how it goes "wrong".

@tristam I know this is 10 years later, but have you figured out this issue?

@jhayar Could you please describe your solution to the "Can't toast on a thread that has not called Looper.prepare()"?

@RayKn said in Translating between NL and EN:

What do I do at initialization? Do I install the dutch translator even though the program is already set at dutch (also in QT Creator Designer the language is set to dutch).
I really feel like I am missing something.

The Qt translation system at runtime doesn't know anything about specific langauges. It just checks the installed QTranslators one by one whether they provide a translation for the source string / context combo, falling back to the original source string if nothing is found.

If you don't need a nl translation because all the source strings are already in correct language , then you can as well remove the .nl file. Then all you have to do to switch from English to Dutch is to remove the translation file by calling QCoreApplication::removeTranslator() with the QTranslator object as argument.

Sometimes it's useful though to keep a (partial) translation, for instance to be able to fix typos, or to handle plural forms correctly. In this case, you might want to have a partial .ts file for NL (-pluralsonly argument).

That said, if it's true that the nl file is contains a correct translation, then your setup should actually work (even if slightly inorthodox). I suggest at least checking the return value of your installTranslator calls...

Hi, and welcome!

@joeren said in Integration of QML and C++:

The application that will publish the interface onto the module is called G2Link and will only push QML files.

This sounds like a non-standard setup. I had a quick look at their website, but I can't see how to program their device using C++ at all.

Your best bet is to contact tech support at Reach Tech.

At the beginning of times, creating a GUI, be it on Windows or Linux, was something that wasn't easy to learn nor do and was not reusable at all. Qt was created to make the life of developers way easier as well as provide a framework that allows you to write your code once and then build it on a per platform basis. If you want another example, try to show an OpenGL window using native APIs vs doing with Qt.

Qt is:

I figured it out.

Something new for this topic:

QML/HTML Browser based on QT and Chrome.
Support most of QML features like 2D, 3D, Charts, Multimedia and other stuff.
