Python function errors in Qtdragon with Linuxcnc 2.9

I have a fresh install from a compiled linuxcnc 2.9 downloaded a couple of days ago. When I try to use the QTDragon sim examples or with any of my INI files, the interface launches but I get a lot of python3 errors related to drawing functions pop up.  Like the below:



Traceback (most recent call last):File "/usr/lib/python3/dist-packages/qtvcp/widgets/round_gauge.py", line 53, in paintEventself.draw_background(painter, event, w)File "/usr/lib/python3/dist-packages/qtvcp/widgets/round_gauge.py", line 69, in draw_backgroundfp = QPoint(center.x() - w/4, center.y() - w/4)TypeError: arguments did not match any overloaded call:QPoint(): too many argumentsQPoint(int, int): argument 1 has unexpected type 'float'QPoint(QPoint): argument 1 has unexpected type 'float'


OR

Any ideas?



 

Can you tell me more about your linux system?
Ot seems the drawing routines changed at some point in the pyqt libraries.

Running bulleye where I downloaded and compiled my own 2.9 package. All dependencies were downloaded based on the dpk tools as part building the linuxcnc deb packages. I modified all the python widgets by adding explicit type casting to int (using the int() function). This seems to have resolved the issue however I keep getting segmentation errors when I exit:


qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 31034, resource id: 9583230, major code: 40 (TranslateCoords), minor code: 0
/usr/bin/linuxcnc: line 963: 17340 Segmentation fault $EMCDISPLAY -ini "$INIFILE" $EMCDISPLAYARGS $EXTRA_ARGS

yes seg error when closing sees to be a common complaint. I have npt found the answer yet, but seems harmless other then annoying.

Just wanted to leave this update here: there is no need to modify any of the widget drawing function calls if using python 3.9, the issue seems to be specific to the version of the libraries of python 3.10

if you could, check out my problem....

forum.linuxcnc.org/qtvcp/46757-qtdragon-...n-12-bookworm#250629

did you revert from python 3.10 to python 3.9 ???
if so, how ???

No, the culprit was the way I had my apt repos setup. Basically had it pointing to testing or unstable and during the process of install the Linuxcnc build dependencies. Python3.10 was the candidate to resolve some of the package. There was no way to revert easily, so I ended up reinstalling my build environment and stuck with the main repos from bullseye. As mentioned on the other thread, you can edit the files that have the invalid function calls with a data type override(int()) but it’s not a sustainable solution if you want to close to the master branch so I’d recommend sticking to Debian 11 and python 3.9

Eyecon.
thanks for the reply.
a bit too late to revert to 11.....
sounds like Cmorley is going to look into more...
