I am currently learning python and I am trying to get a tkinter button to pass variables from several entry fields to a function in another file. The button calls the scan function inside another module.
For some reason the function is getting executed as soon as I start and not on clicking the button.I dont understand why. Find button under # Start Scanning button I am hoping for your support
from tkinter import *
from PIL import Image, ImageTk
from Sockets_Portscanner_threaded import *
# Here, we are creating our class, Window, and inheriting from the Frame
# class. Frame is a class from the tkinter module. (see Lib/tkinter/__init__)
class Window(Frame):
# Define settings upon initialization. Here you can specify
def __init__(self, master=None):
# parameters that you want to send through the Frame class.
Frame.__init__(self, master)
#reference to the master widget, which is the tk window
self.master = master
#with that, we want to then run init_window, which doesn't yet exist
self.init_window()
#Creation of init_window
def init_window(self):
# changing the title of our master widget
self.master.title("GUI")
# allowing the widget to take the full space of the root window
self.pack(fill=BOTH, expand=1)

The scan function in this button is in the Sockets_portscanner_threaded file

try:
con = s.connect((target,port))
with print_lock:
print('port',port,'is open!')
portlist.append(port)
print(portlist)
con.close()
