Salve a tutti,
ho un quesito per l'utilizzo delle librerie grafiche Tkinter.
Sto provando ad utilizzare Page (Gui Rad basato su Tcl) ed ho notato che
creata la maschera grafica, vengono generati due file:
1. descrive la maschera grafica (scritto in codice python)
2. l'altra di supporto per i comandi (scritto in codice python)
Proprio su quella di supporto sui comandi non riesco a capire come accedere
ai valori inseriti.
Ad esempio, ho creato una GUI per fare la somma tra due numeri, il cui
codice è qui riportato ("calcola_somma.py"):
#! /usr/bin/env python
#
# GUI module generated by PAGE version 4.5
# In conjunction with Tcl version 8.6

Page poi crea un altro file di supporto dove sono elencate le procedure
relative ai vari comandi (ovvero nel caso in cui vengano premuti i vari
pulsanti che ho messo):

def calcola():

global w, top_level, root
w = gui
top_level = top
root = top
def destroy_window():
# Function which closes the window.
global top_level
top_level.destroy()
top_level = None
La mia domanda è: come collego al pulsante "Calcola" la procedura "calcola"
contenuta nel file "calcola_somma_support.py" ?
Qualcuno può aiutarmi a completare il codice per renderlo funzionante ?
