Select all in a tkinter Listbox

Question

I am creating a Listbox using Tkinter and Python. I want to make a Button for select all, but I can't find any info regarding selecting elements using code.

 self.l = Listbox(self, height=12, selectmode=MULTIPLE)
 self.selectAll=Button(self, text="select all",
                      command=self.selectAllCallback())
 def selectAllCallback(self)
 # What to do here

You can use selection_set (or select_set) method with 0 and END as arguments.

For example, try following code:

from Tkinter import *

def select_all():
    lb.select_set(0, END)

root = Tk()
lb = Listbox(root, selectmode=MULTIPLE)
for i in range(10): lb.insert(END, i)
lb.pack()
Button(root, text='select all', command=select_all).pack()
root.mainloop()

In the following statement, you are calling self.selectAllCallback, not bind it with button click. It is called before the button is generated.

self.selectAll=Button(self,text="select all", command=self.selectAllCallback())
                                                                            ^^

It should be:

self.selectAll=Button(self, text="select all", command=self.selectAllCallback)
