Qt for Python

@Mahdi_2020 said in Error in exe file: IndexError: list index out of range line338: root_object = engine.rootObjects()[0] engine.rootObjects() is not an array or, more likely, is an empty array so [0] is out of range. If it works under Creator but not outside then presumably creating the engine/objects fails outside because something is not set up right in the environment. When I run my program exe file When using Python you do not have an executable file, just a bunch of .py file scripts.

@cjw25 said in QFileDialog not started in needs dir: But the compilers on the other OSs are complaining that passing in zero is deprecated What dos this mean?

I've found a solution using QAbstractNativeEventFilter to grab the keyboard events that never make it to the standard Qt event system.

@JonB said in QStyleOptionViewItem.rect: @MasterQ said in QStyleOptionViewItem.rect: no, there is really no rect, see the documentation of PySide I provided. The IDE is right! No, there is indeed a rect member! Thank you for that information. My last tests confirm your answer, I was wrong about missing rect. Sry for the confusion.

@jsulm said in QSystemTrayIcon doesn't show messages: I think it is the title of your application, try to change that Hi @jsulm, many thanks for your reply. I just tried both: QApplication.setApplicationDisplayName and QApplication.setApplicationName, but do not work. Any other idea? Cheers

Yes, it is PySide 6.8.0.2 on both OS. But on Linux I use Python 3.12 and on Windows 3.13 --Edit: -- the Python version doesn't matter!, Just tested.

@SGaist The problem with doing that is that it will reset the current transform, defeating the purpose of scaling/rotating the item.

Hi, Is that related to this thread ?

Where in that code is the cropping done ?

A QTableWidget doesn't seem to be most solution thing for this, you are not presenting data. A QHboxLayout of QVBoxLayout would be the solution I'd try.

@MasterQ said in Logging: What does the qCWarning, qCDebug, ... do? The first parameter is an object. What object? I could not find a suitable documentation. This is for categorized logging, more info here: https://doc.qt.io/qt-6/qloggingcategory.html. I don't know if it works with Python.

@mlperini My 2 cents. Only my assumptions. The pip install of PySide6 is intended for Python use and deliberately standalone/self-contained/isolated from whatever Qt6 you may or may nor have outside on the system. If you have an incompatible version out there it doesn't matter. Conversely the non-Python world just sees what is out there in the system, nothing to do with the Python. So again if they're incompatible it doesn't matter. This works fine for distinct applications. But I can imagine that if you want to mix Python and system/C++ in one process don't you need them to be the exact same version to avoid grief?

Oh dear, it's Friday. the isue was that I called i11 = ProjectsTreeItem(["11", "12"]) instead of i11 = ProjectsTreeItem(["11", "12"],i1) I've forgotten to give the parent parameter, which is set to None as default.

@GrecKo Thanks! That's very helpful~
