Check state of button in tkinter

Question

On a tkinter GUI I want to print different messages on a canvas depending on the state of a button I hover over. If the button itself is DISABLED, I want to display another message on the canvas than when the button is NORMAL. I have this (stripped) relevant code:

from tkinter import * class app: def __init__(self): self.window = Tk() self.button = Button(self.window,text="Button",command=self.someCommand,state=DISABLED) self.button.bind("<Enter>", self.showText) self.button.bind("<Leave>", self.hideText) self.window.mainloop() def showText(self): if self.button["state"] == DISABLED: #print this text on a canvas else: #print that text on a canvas def hideText(self): #remove text def main() instance = app() main()

This always draws 'that text' on the canvas, instead of 'this text'

I have tried the following too:

 self.button['state'] == 'disabled' == 'DISABLED'

if I print:

print(self.button["state"] == DISABLED)

it gives me:

False

Changing the state using:

self.button["state"] = NORMAL

works as I would expect.

I have read through a few topics here but none seem to answer the question to why the if-statement doesn't work.

After some more research I finally got a solution.

print(self.button['state'])

prints:

disabled

So I could use:

state = str(self.button['state']) if state == 'disabled': #print the correct text!

super easy way to do it! Thanks for that, saved me a lot of time

WhyWhat Over a year ago

Note: self.button['state'] does not return a string. Instead, it returns <class '_tkinter.Tcl_Obj'>

@WhyWhat That's because you're using ttk.Button (see my answer)

if you're using ttk.Button then

button = ttk.Button(text=text, command=command) print(str(button['state']))

State returns the string only. And also for me if state == DISABLED: works fine.

Only difference is I'm not using this inside class: But inside my main program.

from tkinter import * app_win = Tk() name_btn = Button(app_win,text = 'aaaaaaa') name_btn.pack() print(name_btn["state"]) #normal app_win.mainloop()
