wxFormBuilder with Python: access FlexGridSizer from subclass

Question

I'm building a GUI in wxFormBuilder and writing the code for it in Python.

I've noticed that all the widgets I've built are assigned to self in the generated code. For example, a GUI with a single piece of text might look like:

class MyFrame(wx.Frame):
    def __init__(self,parent):
        wx.Frame.__init__(self,parent)
        self.myStaticText = wx.StaticText(self,wx.ID_ANY,'My Text',0)

So the object myStaticText becomes an attribute of the MyFrame class. This is good, because I can write a new class that inherits this one and then perform other functions, such as updating the myStaticText object:

import MyFrmae
class GUI(MyFrame):
    def __init_(self,parent):
        MyFrame.__init__(self,parent)

    def updateText(self):
        self.staticText.SetLabel('My Other Text')

The problem is wxFormBuilder does not append a self in front of any FlexGridSizer objects. So the generated code looks like:

myFlexGridSizer = wx.FlexGridSizer(3,1,0,0)

instead of:

self.myFlexGridSizer = wx.FlexGridSizer(3,1,0,0)

As a result, I cannot access that object from any other class, which I really need to do.

So...

1. Is there a way to access an object from another class if it doesn't have a self in front of it, even if I inherit it directly?
2. Is there a way to change a setting in wxFormBuilder so that it does append the self?

Answer 1

If I understand well you want to access the FlexGridSizer that the form builder has generated ?

I've never used the wxFormBuilder but I think the idea being is is that it creates a wxFlexGridSizer,manipulate it in order to do the layout of the form, and calls SetSizer on your wxWindow ( or wxFrame in your case )and forget about it because the layout is not going to change anymore.

One easy option (but it's not the best) is to call GetSizer on your frame and you can access a wxSizer from there.

The other option is to have a specific sizer member in your MyFrame where you would store the wxFlexGridSizer, but It would probably involve changing the code generated by the wxFormBuilder

Answer 2

I tried simply calling the sizer self.my_sizer in wxFormBuilder 3.10.1 and the generated Python code is okay. I access the sizer like any other member of the generated class.
