How to access 'x' and 'y' values in 'place' attribute of TKinter Checkbutton using Python?

Question

What is the correct syntax for accessing the 'x' and 'y' values in the 'place' attribute of a TKinter Checkbutton? I'm not finding anything to help in the docs and my attempts to guess the syntax haven't worked.

from tkinter import *
window=Tk()
v1 = IntVar()
arCombo = []

C1 = Checkbutton(window, state = "normal", text = "Ctrl", variable = v1)
C1.place(x=275, y=65)

arCombo.append(C1)

# these two successfully retrieve 'text' and 'state':
print(arCombo[0].cget("text"))
print(arCombo[0].cget("state"))

# How to access 'x' & 'y' values in 'place'?
# None of these work:
print(arCombo[0].cget("x"))
print(arCombo[0].cget("place"))
print(arCombo[0].place.cget("x"))
print(arCombo[0].place("x"))

window.title('Title')
window.geometry("800x600+10+10")
window.mainloop()

@acw1668 Gives an error "'list' object has no attribute 'place_info'" — hermitjimx, Feb 12 '23 at 23:13
Try `arCombo[0].place_info()["x"]`. `.place_info()` returns a dictionary. — acw1668, Feb 12 '23 at 23:15
@acw1668 My bad, that works, thank you. Is there some generic way of finding a definitive list of object attributes? I'm new to OO and to Python, still finding my way around. — hermitjimx, Feb 12 '23 at 23:20

You can call the method place_info on a widget that was laid out using place. When called, it will return a dictionary that contains all of the information about all of the values used to place the window.

In your case, the dictionary looks like this:

{   
    'anchor': 'nw',
    'bordermode': 'inside',
    'height': '',
    'in': <tkinter.Tk object .>,
    'relheight': '',
    'relwidth': '',
    'relx': '0',
    'rely': '0',
    'width': '',
    'x': '275',
    'y': '65'
}

You can then query the value in the dictionary as you would with any dictionary. For example, you can print out the x coordinate like so:

print(arCombo[0].place_info()['x'])

Note: the values in the dictionary are all strings. If you want to treat the values as integers you must explicitly convert them to integers.
