Selecting values simultaneously from different Tkinter Listbox widgets in Python 3.5 -

i want program work in way that:

• when click element either of 3 listboxes select adjacent values (example: if select 0 in first listbox, should select value "hello" in second listbox , "world" in third listbox

thanks this question/answer managed make them move simultaneously

the code following:

from tkinter import *  class fase3(frame):      def __init__(self, master):           frame.__init__(self,master)         self.master=master         self.frame=frame(self.master)          self.txtm=label(self, text="example")         self.txtm.grid(row=1, columnspan=5)          self.txt1=label(self, text="1")         self.txt1.grid(row=2, column=1)          self.txt2=label(self, text="2")         self.txt2.grid(row=2,column=2)          self.txt3=label(self, text="3")         self.txt3.grid(row=2,column=3)         self.scrlb=scrollbar(self,orient="vertical")          self.lista1=listbox(self,yscrollcommand=self.yscroll1,exportselection=0)         self.lista1.grid(row=3,column=1)          self.lista2=listbox(self, yscrollcommand=self.yscroll2,exportselection=0)         self.lista2.grid(row=3, column=2)          self.lista3=listbox(self, yscrollcommand=self.yscroll3,exportselection=0)         self.lista3.grid(row=3, column=3)          #self.scrlb.config(command=self.yview)         #self.scrlb.grid(row=3, column=4,rowspan=1) #i chose not place scrollbar because involved frames , makes code longer           in range(3):             self.lista1.insert("end",i)          self.lista2.insert("end","hello")         self.lista2.insert("end","pls")         self.lista2.insert("end","thanks")         self.lista3.insert("end","world")         self.lista3.insert("end","help")         self.lista3.insert("end","alot")      def yscroll1(self, *args):         if  self.lista2.yview()!=self.lista1.yview()!=self.lista3.yview():             self.lista2.yview_moveto(args[0])             self.lista3.yview_moveto(args[0])         self.scrlb.set(*args)      def yscroll2(self, *args):         if  self.lista1.yview()!=self.lista2.yview()!=self.lista1.yview():             self.lista1.yview_moveto(args[0])             self.lista3.yview_moveto(args[0])         self.scrlb.set(*args)      def yscroll3(self, *args):         if self.lista2.yview()!=self.lista3.yview()!=self.lista1.yview():             self.lista1.yview_moveto(args[0])             self.lista2.yview_moveto(args[0])         self.scrlb.set(*args)      def yview(self, *args):         self.lista1.yview(*args)         self.lista2.yview(*args)         self.lista3.yview(*args)        self.pack()  root = tk()  marco= frame(root, padx=100, pady=50)  marco.pack()  lf = fase3(marco)  root.mainloop() 

part of problem is, have function bound every listbox, when add exportselection=0, selects single value, so, example user can select ("0","hello","alot"), purposes make no sense @ (insertion database)

i haven't made process in this, if possible them move simultaneously, should somehow possible them select adjacent values.

you should able copy paste , run on python without problem, made in python 3.

the first thing want bind <<listboxselect>> event detect when option selected in 1 of list-boxes:

def __init__(self, master):      # ...      self.lista1=listbox(self,yscrollcommand=self.yscroll1,exportselection=0)     self.lista1.bind('<<listboxselect>>', self.on_select1)     self.lista1.grid(row=3,column=1)      self.lista2=listbox(self, yscrollcommand=self.yscroll2,exportselection=0)     self.lista2.bind('<<listboxselect>>', self.on_select2)     self.lista2.grid(row=3, column=2)      self.lista3=listbox(self, yscrollcommand=self.yscroll3,exportselection=0)     self.lista3.bind('<<listboxselect>>', self.on_select3)     self.lista3.grid(row=3, column=3)       # ... 

when option selected, want select corresponding option in other list-boxes:

def on_select1(self, event):     # index of selected option.     index = self.lista1.curselection()[0]     # select corresponding options in other list-boxes.     self.select_others(index, self.lista2, self.lista3)  def on_select2(self, event):     # index of selected option.     index = self.lista2.curselection()[0]     # select corresponding options in other list-boxes.     self.select_others(index, self.lista1, self.lista3)  def on_select3(self, event):     # index of selected option.     index = self.lista3.curselection()[0]     # select corresponding options in other list-boxes.     self.select_others(index, self.lista1, self.lista2)  def select_others(self, index, *others):     listbox in others:         # list-box's selection must cleared prevent previous selection remaining.         listbox.selection_clear(0, listbox.size() - 1)         listbox.selection_set(index) 

finally, self.pack() @ end of face3 class misplaced.

class face3(frame):      # ...      self.pack() 

you should pack lf instead:

root = tk()  marco = frame(root, padx=100, pady=50) marco.pack()  lf = fase3(marco) lf.pack()  root.mainloop()
