I made a python script that has a lot of print statements showing what the program is doing rather than just having it just sit there and the python script works fine now I am creating a front end with tkinter. What I used to send the print statements to return them is some thing like this:
test.py
def PrintX():
X = [1,2,3,4,5]
for x in X:
print(x)
My plan is to have a tkinter frame in that I put a label and set the text variable to my function in my script. My tkinter page script looks like this so far:
class TradingBotapp(tk.Tk):
def __init__(self,*args,**kwargs):
tk.Tk.__init__(self,*args,**kwargs)
container = tk.Frame(self)
container.pack(side='top',fill='both',expand= True)
container.grid_rowconfigure(0,weight = 1)
container.grid_columnconfigure(0,weight = 1)
self.frames = {}
for F in (InitalSetup):
frame = F(container,self)
self.frames[F] = frame
frame.grid(row=0,column=0,sticky='nsew')
self.show_frame(InitalSetup)
def show_frame(self,cont):
frame = self.frames[cont]
frame.tkraise()
class InitalSetup(tk.Frame):
def __init__(self,parent,controller):
tk.Frame.__init__(self,parent)
label = tk.Label(self, text='Setup', font = LARGE_FONT).pack()
Frame = tk.Frame(self,width=768,height=576).pack()
lbl = tk.Message(Frame, text='').pack()
button1 = ttk.Button(self, text='Start Setup',command=lambda:callback2(lbl)).pack()
def callback2(object):
old_stdout = sys.stdout
sys.stdout = StdoutRedirectorLabel(lbl)
setup()
#lbl['text'] = sys.stdout.result.strip()
sys.stdout = old_stdout
class StdoutRedirectorLabel(object):
def __init__(self,widget):
self.widget = widget
self.widget['text'] = ''
def write(self, text):
self.widget['text'] += text
app = TradingBotapp()
app.mainloop()
But nothing is showing up, but when I press the button I get self.widget['text'] = '' TypeError: 'NoneType' object does not support item assignment
any help would be much appreciated
Haha... You've fallen victim to one of the classic blunders,, (In all seriousness, I've done this many times before, you're not alone) I believe you need to pack your labels with label1.pack()
after their creation.
