I am trying to plot 1D txt files in a part of the window created using wxpython. For this purpose, a directory selection tool was included which lists all txt files. Now, I would like to select a txt file and plot it in a panel on the right side.
Further, I am thinking to implement a button that does some operations on the data and replot again.
What I have tried is this :

This creates a window as follows :
The right portion is assigned as a panel, and I not sure how to place the matplotlib plot in it. Thank you.
There are several good questions on SE probing this topic, such as Q1 and Q2; however, most are limited to the plot being shown on the main window.
wxGlade includes some wxPython / matplotlib examples. Use these as starting point.

Now I have two Panel Panelone and Paneltwo and use notebook in a Frame
and When I click the button, I want to return the value of Panelone to PanelTwo
like
class PanelTwo(wx.panel):
def __init__(self,parent):
super(PanelTwo,self).__init__(parent)
self.choice1 = wx.ComboBox(self,value=**the Panelone Value**,choices=,style=wx.CB_SORT, pos=(100, 5)) or
self.choice1.SetValue(the Panelone Value)
class Panelone(wx.panel):
def __init__(self,parent):
choicelist = ['1','2','3','5','6']
super(Panelone,self).__init__(parent)
self.choice = wx.ComboBox(self,value="1",choices=choicelist,style=wx.CB_SORT, pos=(100, 5))
self.btn = wx.Button(self, label="Summit",pos=(250, 10), size=(80, 50))
self.Bind(wx.EVT_BUTTON, self.BtnCheck, self.btn)
def BtnCheck(self,event):
**When I click the button, I want to return the value of Panelone to PanelTwo**
class Game(wx.Frame):
def __init__(self, parent, title):
super(Game, self).__init__(parent, title=title, size=(900, 700))
self.InitUI()

First of all, if you are learning, I recommend that you use WxGlade to build your graphical interfaces. Your code is pure spaghetti and is full of syntactic errors :(.
In the case of your example, it is very simple since all the elements belong to the same file and are in the same class.
For example:
#!/usr/bin/env python
# -*- coding: UTF-8 -*-
import wx
# THE MAIN FRAME:
class MainFrame(wx.Frame):
def __init__(self, *args, **kwds):
kwds["style"] = kwds.get("style", 0) | wx.DEFAULT_FRAME_STYLE
wx.Frame.__init__(self, *args, **kwds)
self.SetSize((734, 501))
# The main notebook:
self.main_notebook = wx.Notebook(self, wx.ID_ANY)
# Notebook's panels:
self.panel1 = wx.Panel(self.main_notebook, wx.ID_ANY)
self.panel2 = wx.Panel(self.main_notebook, wx.ID_ANY)
# Content of panel1:
self.choiceFruits = wx.Choice(self.panel1, wx.ID_ANY, choices=[])
self.btn_send = wx.Button(self.panel1, wx.ID_ANY, "Send Value to Panel2")
#Content of panel2:
self.txt_result = wx.TextCtrl(self.panel2, wx.ID_ANY, "")
#Binding events:
# event, custom event handler, gui element

self.__do_layout()

self.SetTitle("frame")
choices = ['Apple', 'Banana', 'Peach', 'Strawberry']
self.choiceFruits.SetItems(choices)
self.choiceFruits.SetSelection(0)
def __do_layout(self):
# begin wxGlade: MainFrame.__do_layout
sizer_1 = wx.BoxSizer(wx.VERTICAL)
grid_sizer_2 = wx.FlexGridSizer(2, 1, 0, 0)
grid_sizer_1 = wx.FlexGridSizer(2, 2, 0, 10)
label_1 = wx.StaticText(self.panel1, wx.ID_ANY, "Choose a fruit:")
grid_sizer_1.Add(label_1, 0, wx.ALL, 10)
grid_sizer_1.Add((0, 0), 0, 0, 0)
grid_sizer_1.Add(self.choiceFruits, 0, wx.BOTTOM | wx.EXPAND | wx.LEFT | wx.RIGHT, 10)
grid_sizer_1.Add(self.btn_send, 0, wx.BOTTOM | wx.EXPAND | wx.RIGHT, 10)

self.SetSizer(sizer_1)
self.Layout()
# end wxGlade
# Custom event handler:

self.txt_result.SetValue(selectedFruit)

But this is not common. Usually each panel will be in a separate file within its own class. In that case, you must pass a reference from the main frame to each panel and then we use this reference to access the elements on the main frame (for example, another panel).

I have two BoxSizers, the first one
sizer = wx.BoxSizer (wx.VERTICAL)
sizer.Add (self.grid2, 1, wx.EXPAND)
panel2.SetSizer (sizer)
and another vertical BoxSizers, to the left of the button grid, both BoxSizers interfere.
vbox1 = wx.FlexGridSizer (rows = 1, cols = 3, hgap = 5, vgap = 5)
buttonsBox1 = wx.BoxSizer (wx.VERTICAL)
buttonsBox1.Add (self.buttonoborved)
vbox1.Add (buttonsBox1)
vbox1.Add (self.grid2)
vbox1.Add (midPan1, wx.ID_ANY, wx.EXPAND | wx.ALL, 20)
panel2.SetSizer (vbox1)
An error occurs - Adding a window already in a sizer, detach it first!
How can they be called at the same time.
Edit:
That are two BoxSizer, one in other, but how can be put buttons in there.

LoginDialog is opened with self.loginButton, and upon closing it, the GUI freezes; the login button remains pressed, and there are only alert sounds when attempting to click on anything.
LoginDialog() was from this tutorial, just augmented with the file-write line in onLogin (which isn't the problem source). All appears to work when switching from self.Destroy() to self.Close().

If a dialog is intended to be used with ShowModal dialog then the dialog should call EndModal when it is done, and the caller should be the one who calls Destroy after it has fetched values from the dialog if needed.

What can I do?
I don't like the grid sizers because I find them pretty confusing. So I typically take something like this and draw boxes around the various groups. The boxes represent BoxSizers. Once I have that done, I know what to do and write my code accordingly. Here's how I would lay this out:
import wx

wx.Panel.__init__(self, parent, size=(200, 100))

im having a little issue with NoteBook switching. When I switch notebook tabs, I will need to resize to make the wigdets display properly. I tried using self.Refresh() but that does not seem to do anything. If you have trouble understanding me, please run the following code, then switch tabs and resize, you will notice that there is problems, displaying things correctly. I do not know if this is a problem with wxPython but I think it is with my code.

Thank you very much.
Just change the self.Refresh() to self.Layout(). Worked for me on Windows 7 anyway.
