I have scripted a class below. I basically take some values from a csv file and populate it on the GUI. The listbox populates well and is also selectable. However, before I can even make a selection, I see the "Empty!" comment on my console. Why is my listbox not populating even though its visible on the GUI?
class Table:
def __init__(self):
pass
def get_selection(self):
n = self.lbx.curselection()
if n:
self.s = self.lbx.get(n)
print(self.s)
else:
print('Empty!')
def clicked_new_order(self):
df = pd.read_csv('data/teno_menu.csv', encoding='unicode escape')
cat = df.category.unique()
from main_screen import M
self.lbx = tk.Listbox(M.disp_frame, background="#ffffbb", foreground="#07ba80",
cursor="hand2", justify='center', relief='flat', selectmode='single',
activestyle="dotbox", selectbackground="#00ca00",
font="-family {arial} -size 12 -weight bold")
self.lbx.place(relx=0.28, rely=0.265, relheight=0.7, relwidth=0.4)
t = []
for ind, item in enumerate(cat):
self.lbx.insert(ind, item)
t.append(item)
print(t)
self.lbx.bind('<<ListboxSelect>>', self.get_selection())
When I run the main file that calls this class it works without errors but the lbx.curselection()[0] is always returning empty. What am I missing?
