Suppose I have an array of sizers, each size containing a

For each button/textctrl, I'm implementing a right-click menu that
allows color changes or label changes. After all the changes, I want to
be able to export all these data to a file that can be imported later.
I'm trying to use sizer mainly because of its 'nicely layout capability'

You can use sizer.GetChildren() to get a list of the child widgets of
a sizer. But, maybe I am just not getting it, but I am unsure why you
can't just have a list of the widget objects and appeal to that. That is,
if you know you will have 5 "units" of a button and a textctrl, when you
want to know the properties, you have a list of those 5 widgets and
you can use .GetValue() or GetBackgroundColour() or whatever the
method is right on the widgets themselves and skip the bit about the
sizer entirely.

Yes, but why bother? It would be more flexible if you separate the UI from your data. You are already binding events to the widgets in order to be able to use them to change colors, etc. So instead of depending on the ability to store and retrieve those values from the widgets themselves, just store the values as they change in some other data structure that the rest of the program uses whenever it wants to access one of the data items.

You can get a list of wx.SizerItem objects, and from those you can get the windows or subsizers that each item is managing. Keep in mind that if you have nested sizers then you'll need to use recursion to get all the child windows. You can also use the parent window's GetChildren to do the same thing without having to go through the wx.SizerItem middlemen or do recursion.

Subject: [wxPython-users] Re: Get info from items inside a sizer
For each button/textctrl, I'm implementing a right-click menu that
allows color changes or label changes. After all the changes, I want
to
be able to export all these data to a file that can be imported later.
I'm trying to use sizer mainly because of its 'nicely layout
capability'
compared to manual positioning all the widgets. Of course, when I
generate this array of widgets within sizers, I can store the widget
objects somewhere. I'm just curious, suppose I 'forgot' to store the
widget objects. Can these widget objects be retrieved from the sizers
themselves so I can get the widget's colors/labels?
Yes, but why bother? It would be more flexible if you separate the UI from your data. You are already binding events to the widgets in order to be able to use them to change colors, etc. So instead of depending on the ability to store and retrieve those values from the widgets themselves, just store the values as they change in some other data structure that the rest of the program uses whenever it wants to access one of the data items.

Haha exactly. That's why I need to get out of that mindset.

you're not keeping copies, only references, so it's not much extra
memory, certainly not compared to everything else you're using here!
