Hi All,
I hope this makes sense
I am trying to write a GUI where you click on a button and each time
you click on the button it shows in the entry text how many times you
have clicked. However when I changed an earlier version of the code to
pass a parameter it errors.
This works :-
from Tkinter import *
class Application(Frame):
"""GUI App"""
def __init__(self, master):
"""Initialize the frame."""
Frame.__init__(self, master)
self.grid()
self.create_widgets()
def create_widgets(self):
self.inst_lbl=Label(self, text="Click on the button to get
instructions")
self.inst_lbl.grid(row=0, column=0, columnspan=2, sticky=W)
self.pw_lbl=Label(self, text="Password")
self.submit_bttn=Button(self, text="Submit", command=self.reveal)
self.submit_bttn.grid(row=1, column=1, columnspan=2, sticky=W)
self.secret_text=Text(self, width=35, height=5, wrap=WORD)
self.secret_text.grid(row=2, column=1, columnspan=2, sticky=W)
self.helpinfo()
def reveal(self):
Calmexob = Calmex()
results = Calmexob.getmess()
self.secret_text.delete(0.0, END)
self.secret_text.insert(0.0,results)
def helpinfo(self):
self.secret_text.insert(0.0,"Start")
class Calmex(object):
def __init__(self):
"""Default arg"""
def getmess(self):
mesg="Test"
return mesg
#main
root=Tk()
root.title("Test")
root.geometry("400x300")
app=Application(root)
root.mainloop()
But when I changed it to use a number I get an error message.
Here is the code
from Tkinter import *
class Application(Frame):
"""GUI App"""
def __init__(self, master):
"""Initialize the frame."""
Frame.__init__(self, master)
self.grid()
x=0
self.create_widgets(x)
def create_widgets(self,x):
self.inst_lbl=Label(self, text="Click on the button to get
instructions")
self.inst_lbl.grid(row=0, column=0, columnspan=2, sticky=W)
self.pw_lbl=Label(self, text="Password")
x= self.submit_bttn=Button(self, text="Submit",
command=self.reveal(x))
self.submit_bttn.grid(row=1, column=1, columnspan=2, sticky=W)
self.secret_text=Text(self, width=35, height=5, wrap=WORD)
self.secret_text.grid(row=2, column=1, columnspan=2, sticky=W)
self.helpinfo()
def reveal(self, x):
Calmexob = Calmex(x)
results = Calmexob.getmess(x)
self.secret_text.delete(0.0, END)
self.secret_text.insert(0.0,results)
x=x+1
return x
def helpinfo(self):
self.secret_text.insert(0.0,"Start")
class Calmex(object):
def __init__(self,x):
"""Default arg"""
def getmess(self,x):
mesg="Test"+str(x)
return mesg
#main
root=Tk()
root.title("Test")
root.geometry("400x300")
app=Application(root)
root.mainloop()
The error message is
AttributeError: Application instance has no attribute 'secret_text'
The only change is that I have declared x and changed the function reveal to
take and pass x as an arguement.
Thanks in advance. I hope this makes sense.
