We will start from a simple tkinter GUI, which looks as follows:

Embed_wxPython.py

Next, we will try to invoke a simple wxPython GUI, which we created in a previous recipe in this chapter.

The following is the entire code to do this in a simple, non-OOP way:

#=========================================================== 
import tkinter as tk 
from tkinter import ttk, scrolledtext  

win = tk.Tk()          
win.title("Python GUI") 
aLabel = ttk.Label(win, text="A Label") 
aLabel.grid(column=0, row=0)     
ttk.Label(win, text="Enter a name:").grid(column=0, row=0) 
name = tk.StringVar() 
nameEntered = ttk.Entry(win, width=12, textvariable=name) 
nameEntered.grid(column=0, row=1) 
ttk.Label(win, text="Choose a number:").grid(column=1, row=0) 
number = tk.StringVar() 
numberChosen = ttk.Combobox(win, width=12, textvariable=number) 
numberChosen['values'] = (1, 2, 4, 42, 100) 
numberChosen.grid(column=1, row=1) 
numberChosen.current(0) 
scrolW = 30 
scrolH =  3 
scr = scrolledtext.ScrolledText(win, width=scrolW, height=scrolH, wrap=tk.WORD) 
scr.grid(column=0, sticky='WE', columnspan=3) 
nameEntered.focus()   

#=========================================================== 
def wxPythonApp(): 
    import wx 
    app = wx.App() 
    frame = wx.Frame(None, -1, "wxPython GUI", size=(200,150)) 
    frame.SetBackgroundColour('white') 
    frame.CreateStatusBar() 
    menu= wx.Menu() 
    menu.Append(wx.ID_ABOUT, "About", "wxPython GUI") 
    menuBar = wx.MenuBar() 
    menuBar.Append(menu,"File")  
    frame.SetMenuBar(menuBar)      
    frame.Show() 
    app.MainLoop() 

action = ttk.Button(win, text="Call wxPython GUI", command=wxPythonApp)  
action.grid(column=2, row=1) 

#====================== 
# Start GUI 
#====================== 
win.mainloop() 

Running the preceding code starts a wxPython GUI from our tkinter GUI after clicking the tkinter button control:
