Qt for Python

The chart example is an interesting starting point.

From the looks of it, it seems like having the animation available for both direction is the easy path.

Changes in enums types has come up several times on the PyQt mailing list. You might find a better answer there, or a fix if the behavior is unintentional.

@jeremy_k Oh I agree, and I am guessing that is what is happening. I am not a regular Python/PySide user, only occasional. At design time in the IDE I thought if you click on Qt.ItemFlag.ItemIsSelectable is takes you straight to an imported file where that is defined as a number in an enum. Which makes you (me) kind of think that can be done as a constant. But I suppose that is wishful thinking. Assuming the slow lookup is indeed required, it makes one reflect at just how many seemingly innocuous expressions, especially Qt ones, may be dotted around the code which could be in this situation and could be optimized if the coder happens to notice ad think about them. Which the OP may wish to look into if speed is such an issue.

@ajitjohn said in Failed to install QT designer using Python 3.12.3 (URGENT HELP): install pyside6 which is supported in python latest versions . Once you installed it search for pyside6-designer.exe in your pc My path is C:\Users\user\AppData\Local\Programs\Python\Python312\Scripts\pyside6-designer.exe Side comment. Please try to use virtual environments, and avoid installing Python Packages system-wide. It's the number 1 problem when people report that 'a module' doesn't work on Python projects. In each project, you could have one by: $ cd my_project my_project $ python -m venv venv my_project $ venv\Scripts\activate.bat # for cmd my_project (venv) $ python my_project (venv) $ pip install pyside6 Now the Python and Pip you have there is tied to that local venv.

Similarly to what was discussed in https://forum.qt.io/topic/159077/moving-away-from-qt3d-is-qtquick3d-ready/2 I'd say you might need to evaluate if you can: Rely on QtRHI for a new rendering ad-hoc system Check if Qt Quick 3D is enough for your project. Because it's not tied anymore to the qt meta repo, we might face issues from the Qt for Python side of things, and we might stop providing it in newer versions. So far, it's present in 6.9, and hopefully we can provide it for 6.10. Like any piece of software, being deprecated since 6.8, Qt3D will not get new features, or might not have active development. I wouldn't expect for it to go completely away in 1-2 years, but it's highly probable that it might be fully replaced in a few years. This is only my 'feeling' and not what it will happen.

Hi, Any news about that? I’m trying to use a Pyside6 app without desktop with KMS. It works with linuxfb but I need to rotate the screen and it’s not possible on that platform.

Hi, I still have this issue with QMediaPlayer for the same purpose, using @jeertmans great manim-slides library. I would like to create a smooth transition "at the end of the next loop", but again the loop runs 2 more times before stopping. Any idea where this could come from? Thanks in advance

See also https://doc.qt.io/qtforpython-6/tutorials/basictutorial/uifiles.html#tutorial-uifiles . If you create a Python project in Qt Creator, it will do this automatically when running the project.

Solved: Missing parenthesis in self.mod_Indication = QtSql.QSqlQueryModel correct: self.mod_Indication = QtSql.QSqlQueryModel()

@SGaist said in Centered text in QGraphicsView: self.setSceneRect(0, 0, self.viewport().width(), self.viewport().height()) Thank you. Yes, that is indeed what was missing. I had this line before, but probably at the wrong place, so I discarded it.

@memyselfandi Important is to not to mix different Qt versions

Hi and welcome to devnet, Which position do you mean ? In widget coordinates ? The number of chars from the start of the text ?

14/5000 So in the end, in what way was it solved?

I know this post is old, but in my case when I got this error, I was missing the tomlkit module in my python installation.

After doing some digging I found this thread. My Python project on Raspberry Pi OS requires PySide6==6.8.3 or later which depends on glibc 2.39 but RPiOS only provides 2.36. I tried building from source and containerising it with chroot but neither produced the proper result. I'm going try switching to Ubuntu Server 24.04 for Raspberry Pi and hope for the best seeing as it will have the proper glibc version. If I don't report back within the week assume that it worked.
