Display realtime output of a subprocess in a tkinter widget

Question

My question is almost the same as this one: Widget to Display subprocess stdout? but a step further.

I have the following code (python2.7):

def btnGo         


        

Answer 1

Finally I found the solution. After the window construction, you must add :

frame.pack()
# force drawing of the window
win.update_idletasks()

And then after every line insertion in the widget, you must also force a refresh with the same method only on the widget.

# insert the line in the Text widget
t.insert(tk.END, out)
# force widget to display the end of the text (follow the input)
t.see(tk.END)
# force refresh of the widget to be sure that thing are displayed
t.update_idletasks()
