Sorry for spamming. I got it working, except for one error when I click on the item in the list:

As for the above code, the solution was to insert but NOT delete:
# highlights the current analysis in the list
def highlight_current_analysis(analysis_listbox, analysis_index, filtered_data):
# check that the analysis is reduced and that the symbol is ☐ before changing to ☑
if filtered_data[analysis_index].reduced and analysis_listbox.get(analysis_index)[0] == '☐':
analysis_listbox.insert(analysis_index, f'☑ {filtered_data[analysis_index].analysis_label}')
analysis_listbox.activate(analysis_index)
# moves to the selected analysis when clicked in the list
def on_analysis_select(analysis_listbox, filtered_data, fit_type, figure, canvas, stats_frame):
global analysis_index
analysis_index = analysis_listbox.curselection()
interactive_update(filtered_data[analysis_index], fit_type, figure, canvas, stats_frame)
update_buttons(filtered_data)
analysis_listbox.unbind("<<ListboxSelect>>")
highlight_current_analysis(analysis_listbox, analysis_index, filtered_data)
analysis_listbox.bind("<<ListboxSelect>>",
lambda event: on_analysis_select(analysis_listbox, filtered_data, fit_type, figure, canvas, stats_frame)
)
from ctklistbox.

I've made some progress here:
analysis_list_var = tk.StringVar()
analysis_list = []
for analysis in filtered_data:
if analysis.reduced:
analysis_list.append(f'☑ {analysis.analysis_label}')
else:
analysis_list.append(f'☐ {analysis.analysis_label}')
analysis_list_var.set(analysis_list)
analysis_listbox = CTkListbox(right_frame, width=220)
analysis_listbox.listvariable = analysis_list_var
analysis_listbox.pack(side=tk.BOTTOM, fill=tk.BOTH, expand=True)
analysis_listbox.bind("<<ListboxSelect>>",
lambda event: on_analysis_select(analysis_listbox, analysis_list_var, filtered_data, fit_type, figure, canvas, stats_frame)
)
and
# highlights the current analysis in the list
def highlight_current_analysis(analysis_listbox, analysis_list_var, filtered_data):
global analysis_index
# check that the analysis is reduced and that the symbol is ☐
if filtered_data[analysis_index].reduced and analysis_list_var.get()[analysis_index][0] == '☐':
print('checking box')
analysis_list_var.set(analysis_list_var.get()[:analysis_index] + f'☑ {analysis_list_var.get()[analysis_index+3:]}')
analysis_listbox.update_listvar()
analysis_listbox.activate(analysis_index)
# moves to the selected analysis when clicked in the list
def on_analysis_select(analysis_listbox, analysis_list_var, filtered_data, fit_type, figure, canvas, stats_frame):
global analysis_index
selected_item = analysis_listbox.curselection()
analysis_index = int(analysis_listbox.get(selected_item))
interactive_update(filtered_data[analysis_index], fit_type, figure, canvas, stats_frame)
update_buttons(filtered_data)
highlight_current_analysis(analysis_listbox, analysis_list_var, filtered_data)
This should work, however, I'm encountering an empty list instead of a populated one. I can also confirm that anaylsis_list_var isn't empty:
analysis_list_var: ('☑ CB2244 5min', '☑ LB1023', '☑ LB1024', '☑ Q3778_', '☑ Q3779_', '☑ DT913_', '☑ Q3780_', '☑ DT914_', '☑ Q3781_', '☑ DT915_', '☑ Q3782_', '☑ Q3783_', '☑ LB1025', '☑ LB1026', '☑ CB2245 5min')

With a friend's help I figured out that I shouldn't be calling listboxvar or update_listbox, but just inserting and deleting items like normally.
So I've come back to this configuration:
# insert items into the analysis listbox
analysis_listbox = CTkListbox(right_frame, width=220)
for i, analysis in enumerate(filtered_data):
if analysis.reduced:
analysis_listbox.insert(i, f'☑ {analysis.analysis_label}')
else:
analysis_listbox.insert(i, f'☐ {analysis.analysis_label}')
analysis_listbox.pack(side=tk.BOTTOM, fill=tk.BOTH, expand=True)
analysis_listbox.bind("<<ListboxSelect>>",
lambda event: on_analysis_select(analysis_listbox, filtered_data, fit_type, figure, canvas, stats_frame)
)
with these helper functions:
# highlights the current analysis in the list
def highlight_current_analysis(analysis_listbox, filtered_data):
global analysis_index
# check that the analysis is reduced and that the symbol is ☐ before changing to ☑
if filtered_data[analysis_index].reduced and analysis_listbox.get(analysis_index)[0] == '☐':
analysis_listbox.delete(analysis_index)
analysis_listbox.insert(analysis_index, f'☑ {filtered_data[analysis_index].analysis_label}')
analysis_listbox.activate(analysis_index)
# moves to the selected analysis when clicked in the list
def on_analysis_select(analysis_listbox, filtered_data, fit_type, figure, canvas, stats_frame):
global analysis_index
analysis_index = analysis_listbox.curselection()
print(analysis_index)
interactive_update(filtered_data[analysis_index], fit_type, figure, canvas, stats_frame)
update_buttons(filtered_data)
analysis_listbox.unbind("<<ListboxSelect>>")
highlight_current_analysis(analysis_listbox, filtered_data)
analysis_listbox.bind("<<ListboxSelect>>",
lambda event: on_analysis_select(analysis_listbox, filtered_data, fit_type, figure, canvas, stats_frame)
)
however, the behavior is extremely erratic with the analysis clicked sometimes being deleted and never re-added, sometimes another sample's name is deleted and re-added, etc accompanied by the following errors:

Any idea on the error I'm getting and how I can hide/resolve it?

The behavior is totally fine, everything works as expected, this is just a random error I'm trying to clear. It only occurs when I click on an analysis that I haven't touched yet, if I go back to an analysis that has already been seen/loaded then there's no error.

I kinda (for me) fixed the error problem by replacing the code line 125 in ctk_listbox.py by :
self.after(100, lambda: selected_button.configure(hover=self.hover) if selected_button.winfo_exists() else None)
It checks if the selected_button object exists at the time the lamda function is called. (Thanks to GitHub Copilot)
