switch frame with tkinter

Is it possible to switch the frames without using buttons?
e.g. comparing a counter. if the counter value is 1 show page 1
if counter value is 2 show page 2 and so on.
If I'm honest, I do not remember exactly what I've all tried.
One thing I tried was "controller.show_frame("StartPage")" from def printer sub.
What I want to achieve is to switch the pages from the "def printer" sub,
which is called periodically.
I do not know if that's possible?

Yes I have tried it, but no success. That is my problem, that I dont know how to call the e.g. show_frame("PageOne") from my timer event.

Please show what you tried, and show what "no success" means. Though, calling any tkinter code from a separate thread will likely fail, if that's where you're doing it.

The command to switch pages is just a normal method. It's unclear why you're having a problem calling it. There's absolutely nothing special about that method that would prevent you from calling it. If we can't see how you're calling it, we can't say what's wrong.

One thing I tried was
controller.show_frame("StartPage")
from def printer sub.
You have to call switch_frame
on the object that has that method. This is no different than any other object or any other class in python.
In your case, since SampleApp
is the class that has the method, and app
is a global variable that holds an instance of the class, you would do it this way:
app.show_frame("StartPage")
Thank You! Now it works!

controller.show_frame("StartPage")
from def printer sub.
You have to call switch_frame
on the object that has that method. This is no different than any other object or any other class in python.
In your case, since SampleApp
is the class that has the method, and app
is a global variable that holds an instance of the class, you would do it this way:
app.show_frame("StartPage")
Thank You! Now it works!

If a button can call a command, you can call it too. Have you tried calling it?

Yes I have tried it, but no success. That is my problem, that I dont know how to call the e.g. show_frame("PageOne") from my timer event.

Please show what you tried, and show what "no success" means. Though, calling any tkinter code from a separate thread will likely fail, if that's where you're doing it.

The command to switch pages is just a normal method. It's unclear why you're having a problem calling it. There's absolutely nothing special about that method that would prevent you from calling it. If we can't see how you're calling it, we can't say what's wrong.
