Tkinter Dynamic Widget editing
<p>Here is my code:</p>

<pre><code>class render_window:
    def __init__(self, height, width, window_title):
        self.root_window = Tk()
        w = width
        h = height
        ws = self.root_window.winfo_screenwidth() # width of the screen
        hs = self.root_window.winfo_screenheight() # height of the screen
        x = (ws/2) - (w/2)
        y = (hs/2) - (h/2)
        self.root_window.title(window_title)
        self.root_window.minsize(width, height)
        self.root_window.geometry('%dx%d+%d+%d' % (w, h, x, y))

    def new_button(self, button_text, button_command="", grid_row=0, grid_column=0, grid_sticky="NESW", grid_columnspan=1, grid_rowspan=1):
        self.button = ttk.Button(self.root_window, text=button_text, command=button_command)
        self.button.grid(row=grid_row, column=grid_column, sticky=grid_sticky, columnspan=grid_columnspan, rowspan=grid_rowspan)
        self.responsive_grid(grid_row, grid_column)

    def new_label(self, label_text, text_alignment="center", grid_row=0, grid_column=0, grid_sticky="NESW", grid_columnspan=1, grid_rowspan=1):
        self.label = ttk.Label(self.root_window, text=label_text, anchor=text_alignment)
        self.label.grid(row=grid_row, column=grid_column, sticky=grid_sticky, columnspan=grid_columnspan, rowspan=grid_rowspan)
        self.responsive_grid(grid_row, grid_column)

    def new_progress_bar(self, pg_length=250, pg_mode="determinate", grid_row=0, grid_column=0, grid_sticky="NESW", grid_columnspan=1, grid_rowspan=1):
        self.progress_bar = ttk.Progressbar(self.root_window, length=pg_length, mode=pg_mode)
        self.progress_bar.grid(row=grid_row, column=grid_column, sticky=grid_sticky, columnspan=grid_columnspan, rowspan=grid_rowspan)
        self.responsive_grid(grid_row, grid_column)

    def responsive_grid(self, row_responsive=0, column_responsive=0, row_weight_num=1, column_weight_num=1):
        self.root_window.grid_columnconfigure(column_responsive, weight=column_weight_num)
        self.root_window.grid_rowconfigure(row_responsive, weight=row_weight_num)

options_window = render_window(200, 250, "Options Window")

options_window.new_progress_bar()
options_window.progress_bar.start()
options_window.new_progress_bar(grid_column=1)
options_window.progress_bar.start()
options_window.new_label("Options Window\And other buttons...", grid_row=1, grid_columnspan=2)

options_window.root_window.mainloop()
</code></pre>

<p>I have created a system that allows the creation of an interface relatively easily using tkinter. I am having an issue with the modifying of already existing elements, I cannot seem to modify them if I create multiple instances, I can only edit the last one created. when I say modify/edit, I am talking about .config().</p>

<p>So whenever I do:
options_window.progress_bar.config(args_here), it only does that for the last bar created. Is there a way to specify which bar I can execute the code on?</p>

<p>Thanks!</p>

<p>If I understand you correctly... could you not just asign each progressbar to a variable? Ie.</p>

<pre><code>pb1 = options_window.progress_bar
pb1.start()
pb1.conig('etc, etc')
</code></pre>

<p>Sorry if i have misunderstood your problem!</p>

<p>PS - Cool idea!</p>
