I am trying to create multiple tabs using ttk.Notebook widget. I am creating a simple multi-tab notepad. but I don't know how to deal with the NoteBook widget. but when I click on save button it overrides all tabs text area that because of I declared there self.tx.get("1.0","end-1c").all written file change their text according to last text. Thanks for helping me

 import tkinter.ttk as ttks
 from tkinter import LEFT,RIGHT,X,Y,BOTH
 class MainUI:
 def __init__(self,master):
 self.master = master

 self.nb = ttks.Notebook(self.master)
 self.nb.pack(fill='both',expand=1)

 self.name = ttks.Entry(self.master)
 self.name.pack()
 self.save_tab = ttks.Button(self.master,text="save",command=lambda:self.save_file()).pack()
 #tab1
 self.page1 = ttks.Frame(self.nb)
 self.txt = ttks.tkinter.Text(self.page1)
 self.txt.pack(fill='both',expand=1)
 self.nb.add(self.page1,text="tab1")

 self.page2 = ttks.Frame(self.nb)
 self.nb.add(self.page2,text="tab2")
 self.master.bind('',self.add_tabs)

 def add_tabs(self,event):
 self.page_name = ttks.Frame(self.nb)
 self.tx = ttks.tkinter.Text(self.page_name)
 self.tx.pack(fill=BOTH,expand=1)
 self.nb.add(self.page_name,text="pagename")

 def save_file(self):
 self.fname = self.name.get()
 self.txtinput = self.tx.get("1.0","end-1c")
 with open(self.fname,'w') as f:
 f.write(self.txtinput)

 if __name__ == "__main__":
 root = ttks.tkinter.Tk()
 root.title('Tabs>>')
 root.geometry('500x500')
 MainUI(root)
 root.mainloop()

after Implementing below code got following Exception

In add_tabs, you are replacing the value of self.tx each time that a new tab is added. I.e. you only remember the last created text widget. You need to:

• store all the text widgets you create (i.e. using a list)


• have some means to find the text widget in foreground, e.g. by looking at the active tab or the focused widget.

In __init__, add:

self.txs = [] # "s" suffix to discern list and elements

in add_tabs, use:

tx = ttks.tkinter.Text(self.page_name)
self.txs.append(tx) # append to list
tx.pack(...)

in save_file, use:

tab_index = self.nb.index(self.nb.select())
tx = self.txs[tab_index + 1] # may need to adjust depending on how much "static" tabs are in front
txtinput = self.tx.get("1.0", "end-1c")
# ...
