@mdickinson Is this something that should be fixed by the recent compatibility of TraitsUI with the latest PySide 6?

Can you please try running these with current main branch Pyface and TraitsUI to see if these have been fixed, ie. do:

pip install --force-reinstall git+http://github.com/enthought/pyface.git
pip install --force-reinstall git+http://github.com/enthought/traitsui.git

and then try the failing tests. Several errors like this were fixed in Pyface recently.

Hi Corran:

I installed the latest Pyface and TraitsUI, here is the version that is printed out:
traitsui.version 8.0.0.dev0
pyface.version 7.4.4

However, the same error still occurs in many demos such as:

chaco/examples/demo/domain_limits.py
chaco/examples/demo/depth.py

@homosapien-lcy can you test this again with the latest pyface and traitsui?

@homosapien-lcy can you test this again with the latest pyface and traitsui?

The error remains after I reinstalled these two packages with the following command:

python3.11 pip install --force-reinstall git+http://github.com/enthought/pyface.git
python3.11 -m pip install --force-reinstall git+http://github.com/enthought/traitsui.git

Then I ran

python3.11 examples/demo/financial_plot_dates.py

and if I click one the plot and close it, the same error will happen.

Indeed, the latest commit in traitsui is on 4/17 (https://github.com/enthought/traitsui/commits/main) and pyface on 4/6 (https://github.com/enthought/pyface/commits/main), and I don't they are related to this problem
