Closed 7 months ago.

I am trying to create a graphical interface where my results of certain processes of my program are shown on the screen to a text box, to view them from there.

For this I have created a QtextBrowser, the problem is that when loading the results to that widget, nothing appears, a 'NONE' message appears.

The function that prints on screen is called 'calculu', I attach the respective .ui files in the folder. ui FILES

import sys
from PyQt5.QtWidgets import QMainWindow, QApplication
from PyQt5.uic import loadUi

# CLASS WINDOW PRINCIPAL

class mainWindowInicial(QMainWindow):
    def __init__(self, parent=None):
        super(mainWindowInicial,self).__init__(parent)
        loadUi('Gui/principal_main.ui', self)
        self.actionInputs.triggered.connect(self.open_dataInput)      
        self.actionOuputs.triggered.connect(self.open_result)

        DataInput(self).show()

        Result(self).show()
        

def calculu():
    
    print('THIS IS SOME EXAMPLE ....')
    print('Many, many calculus ....')
    print('Many, many calculus ....')
    print('Many, many calculus ....')
    
    print('Hello World')
    print('Hello')
    print('World')
    
    x = np.array([0,0,0])
    
    print(x)
