Specific Version

3.10.1.1

Steps to Reproduce the Problem

Running an embedded python block to a virtual sink

Relevant log output

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/gnuradio/qtgui/toggleswitch.py", line 143, in paintEvent
    painter.drawEllipse(
TypeError: arguments did not match any overloaded call:
  drawEllipse(self, r: QRectF): argument 1 has unexpected type 'float'
  drawEllipse(self, r: QRect): argument 1 has unexpected type 'float'
  drawEllipse(self, x: int, y: int, w: int, h: int): argument 1 has unexpected type 'float'

  drawEllipse(self, center: QPoint, rx: int, ry: int): argument 1 has unexpected type 'float'

I was able to resolve this, locally, by type casting parameters to the drawEllipse calls inside of the paintEvent method

huh, interestingly, it works when I run it from the command line from which I'm also starting GRC-qt, but not from GRC-Qt through execute (the switch is just dead).

ah no wonder I can't reproduce – this was fixed by Volker Schroer in 3.10.2.0, in #5541 .

I don't know PopOS, but seeing it uses apt and it happens to have the old-ish variant still in Ubuntu 22.04LTS: probably, an operating system update will allow you to install a nwer version of GNU Radio, where this is already fixed :)
