I'm building my first app with Tkinter and I'm stuck with instance of class. I followed this tutorial https://pythonprogramming.net/change-show-new-frame-tkinter/ but some questions remain : - how does mean controller as argument for the init line in the differents class ? - I would like to create instance of classA in classB and inversely but I'm getting wrong with arguments ! - About organisation code, I created 2 class (one for each frame) and writting function related in the good one, should I split them in a 3rd class ? What is the most convenient way ? Actualy the code is running but I would like to add some setup tools in the 2nd window ! What do I must do to can modify some parameters in the SettingsPage Class and update and use them in the StartPage class ? For example I would like to modify ecartementlogo.
setp = SettingsPage(controller, StartPage) give me AttributeError: type object 'StartPage' has no attribute 'tk'
Sorry for posting all the code but I not sure about what can I remove for the example

This line used in the SettingsPage Class is ok : startp = StartPage(controller, SettingsPage) I would say I need to write the reverse one but I having error with arguments (controller, StartPage) BUT this one setp = SettingsPage(controller, StartPage) don't work (in the init line of StartPage Class)
