When I check a checkbox in Tkinter the value of checkbox gets vanished.

This problem appears in Linux only.

The same code I am using in windows and it is working Fine.

I Referred this link to make this gui

How to create a tree view with checkboxes in Python

Code:

import Tkinter as tk

import Tix as tix

def  selectItem(item):
        
    if cl.getstatus(item) == 'on':
        print("Checked")
    if cl.getstatus(item) == 'off':
        print("Unchecked")

root = tix.Tk()
cl = tix.CheckList(root,browsecmd=selectItem)
cl.pack()
cl.hlist.add("CL1", text="Test")
cl.setstatus("CL1","off")
cl.hlist.add("CL1.Item1", text="child")
cl.setstatus("CL1.Item1","off")
root.mainloop()

Before check :

Solution

  • I got the solution.Actually the colour of background and foreground was same.therefore i changed the colour of foreground and background.

    import Tkinter as tk

import Tix as tix

def  selectItem(item):

    if cl.getstatus(item) == 'on':
        print("Checked")
    if cl.getstatus(item) == 'off':
        print("Unchecked")

root = tix.Tk()
cl = tix.CheckList(root,browsecmd=selectItem)
cl.hlist.config(bg='White',bd=0,selectmode='none',selectbackground='white',selectforeground='black',drawbranch=True)
cl.pack()
cl.hlist.add("CL1", text="Test")
cl.setstatus("CL1","off")
cl.hlist.add("CL1.Item1", text="child")
cl.setstatus("CL1.Item1","off")
root.mainloop()
