Add the following code to our GUI in the create_widgets() method towards the bottom where we created Tab Control 2. The parent of the new widget frame is tab2, which we created at the very beginning of the create_widgets() method. As long as you place the following code physically below the creation of tab2, it will work:
########################################################### def create_widgets(self): # Create Tab Control tabControl = ttk.Notebook(self.win) # Add a second tab tab2 = ttk.Frame(tabControl) # Make second tab visible tabControl.add(tab2, text='Tab 2') # Create Manage Files Frame mngFilesFrame = ttk.LabelFrame(tab2, text=' Manage Files: ') mngFilesFrame.grid(column=0, row=1, sticky='WE', padx=10, pady=5) ...
