I am working for build a software where I wan't to pause/stop a thread for some time or for a event
here are some essential code to understand you better
self.staff_list_thread = Thread(target = self.get_staff_list, kwargs = {"master": self.frame_staff_list}, daemon = True)
self.staff_list_thread.start()
def get_staff_list(self, master, *args, **kwargs):
def add_staff_button_callback():
self.get_add_staff(self.frame_staff_add)
def detail_edit_staff_button_callback(email):
if email is not None:
self.get_detail_edit_staff(self.frame_staff_detail, email)
row = 1
self.staff_introduction = get_a_label(master, text="This is staff area", row=0, column=0, padx=(10, 10), pady=(10, 10))
self.staff_introduction.config(style="Title.TLabel")

staffs = self.get_staff_queryset()
if staffs is not None:
for staff in staffs:
self.staff_data_button = get_a_button(master, text='{} as {}'.format(staff[1], staff[5]), row=row, column=0, padx=(0, 0), pady=(5, 5), ipadx=10, ipady=10, relief=FLAT, use_ttk=False)
self.staff_data_button.config(command = lambda email=staff[2]: detail_edit_staff_button_callback(email))
row = row + 1
In the end of function I wan't to end of pause the thread and when the new staff is added I wan't to recount or reset the list with current data so I need to run thread again
Here are the button call func

To simply answer your title question, you can pause a thread with the time.sleep()
import time
time.sleep(30) #pause for 30 seconds
With a naive implementation, you could just run this on a loop checking if the function should be called. Be careful that this will lock the whole paused thread.
From the code though I don't really understand where you want to pause it.
To react to an event, pausing a thread is not the right question, you need to implement a subscribe/register and callback logic.

I want to activate the second entry when the checkbox is checked...but the it works the other way around. What am I doing wrong? Based on another question I have posted it seems the event "<ButtonRelease>" occurs before the bonding. Why is that? Can I use "command" in the checkbox instaed?
import tkinter as tk
def set_entry_status(event, var, widg):
print(var.get())
if var.get():
widg[-1]['state'] = 'normal'
else:
widg[-1]['state'] = 'disabled'
def CustomWidget(frame, name, unit, ):
var_e = []
widget_e = []
var_c = tk.IntVar(master=frame, value=0)
widget_c = tk.Checkbutton(master=frame, text='', variable=var_c)
widget_c.grid(row=0, column=0, columnspan=1, padx=5, pady=5, sticky="ns")
label_l = name + " (" + unit + ")" # nome + unità di misura in parentesi per GUI
widget_l = tk.Label(frame, text=label_l, padx=1, pady=1)
widget_l.grid(row=0, column=1, columnspan=1, padx=5, pady=5, sticky="wns")
var_e.append(tk.StringVar(master=frame, value='A'))
widget_e.append(tk.Entry(frame, textvariable=var_e[-1], width=10, state="normal"))
widget_e[-1].grid(row=0, column=2, columnspan=1, padx=5, pady=5, sticky="ns")

widget_e.append(tk.Entry(frame, textvariable=var_e[-1], width=10, state="normal"))
widget_e[-1].grid(row=0, column=3, columnspan=1, padx=5, pady=5, sticky="ns")
# set initial entry state
if var_c.get():
widget_e[-1]['state'] = 'normal'
else:
widget_e[-1]['state'] = 'disabled'
# checkbox - binding
widget_c.bind("<ButtonRelease>", lambda event: set_entry_status(event, var_c, widget_e))
root = tk.Tk()
root.title('My Window')
CustomWidget(root, 'name', 'unit')

Indeed you can use command kwarg like I suggested in my other answer. In that case event must be removed from the arguments of your callback function:
import tkinter as tk
def set_entry_status(var, widg):
print(var.get())
if var.get():
widg[-1]['state'] = 'normal'
else:
widg[-1]['state'] = 'disabled'
def CustomWidget(frame, name, unit, ):
var_e = []
widget_e = []
var_c = tk.IntVar(master=frame, value=0)
widget_c = tk.Checkbutton(master=frame, text='', variable=var_c, command=lambda: set_entry_status(var_c, widget_e))
widget_c.grid(row=0, column=0, columnspan=1, padx=5, pady=5, sticky="ns")
label_l = name + " (" + unit + ")" # nome + unità di misura in parentesi per GUI
widget_l = tk.Label(frame, text=label_l, padx=1, pady=1)
widget_l.grid(row=0, column=1, columnspan=1, padx=5, pady=5, sticky="wns")
var_e.append(tk.StringVar(master=frame, value='A'))
widget_e.append(tk.Entry(frame, textvariable=var_e[-1], width=10, state="normal"))
widget_e[-1].grid(row=0, column=2, columnspan=1, padx=5, pady=5, sticky="ns")
var_e.append(tk.StringVar(master=frame, value='B'))
widget_e.append(tk.Entry(frame, textvariable=var_e[-1], width=10, state="normal"))
widget_e[-1].grid(row=0, column=3, columnspan=1, padx=5, pady=5, sticky="ns")
# set initial entry state
if var_c.get():
widget_e[-1]['state'] = 'normal'

If I understand this correctly you want to enter a password in a dialog and then get the password from the dialog when you close it.
Have a look at Dialog Windows at effbot for a discussion about creating dialog windows.
Here is an example of how you can implement a simple dialog:
from tkinter import *
from tkinter import simpledialog
class MyDialog(simpledialog.Dialog):
def body(self, master):
'''create dialog body.
return widget that should have initial focus.
This method should be overridden, and is called
by the __init__ method.'''
Label(master, text='Value:').grid(row=0)
self.e1 = Entry(master)
self.e1.grid(row=0, column=1)
return self.e1 # initial focus
def apply(self):
'''process the data
This method is called automatically to process the data, *after*
the dialog is destroyed. By default, it does nothing.'''
value = self.e1.get()
self.result = value
def validate(self):
'''validate the data
This method is called automatically to validate the data before the
dialog is destroyed. By default, it always validates OK.'''
return 1 # override
def buttonbox(self):
'''add standard button box.
override if you do not want the standard buttons
'''
box = Frame(self)
w = Button(box, text="OK", width=10, command=self.ok, default='active')
w.pack(side='left', padx=5, pady=5)
w = Button(box, text="Cancel", width=10, command=self.cancel)
w.pack(side='left', padx=5, pady=5)
self.bind("<Return>", self.ok)
self.bind("<Escape>", self.cancel)
box.pack()
if __name__ == '__main__':
root = Tk()
root.geometry('200x100+800+50')
def do():
d = MyDialog(root)
print(d.result)
b = Button(root, text='Go!', width=10, command=do)
b.pack(expand=True)
Did that answer your question?
I am learning python for my A level and have come across a problem in my project, any help would be immensely appreciated. Thank you.
I have a series of tkinter pages that are designed to be linked by one central page. The search, delete and update functions successfully run SQL queries on their own but lose their functionality when called from the main page, I am getting no visible error messages. I am running SQLite 3.11.2 and Python 3.7.3
The main page calls the attendance page like this (triggered using a button):
def ap():
AttendancePage.Attendance(Tk())
The actual attendance page is as follows:
import tkinter as tk

I am trying to add a configuration window in my coupled oscillator simulation. But when I want to get the value of tkinter variables to set up the system, I only get ''.
I tried to change the type from tk.DoubleVar() to tk.StringVar() but nothing seems to works...
Here the code for the configuration frame for one object. Then I create two of them and add them to the configuration frame.
import tkinter as tk
class MassConfig(tk.Frame):
def __init__(self, root, **kwargs):
tk.Frame.__init__(self, root, kwargs)
self.grid()
# Variables :
self.weight = tk.StringVar()
self.vitesse = tk.StringVar()
self.position = tk.StringVar()
self.lbl_weight = tk.Label(self, text='Masse :')
self.lbl_weight.grid(row=0, column=0)
self.entry_weight = tk.Entry(self, textvariable=self.weight, width=5)
self.entry_weight.grid(row=0, column=1)
self.lbl_vit = tk.Label(self, text='Vitesse :')
self.lbl_vit.grid(row=1, column=0, pady=5)
self.entry_vit = tk.Entry(self, textvariable=self.vitesse, width=5)
self.entry_vit.grid(row=1, column=1)
self.lbl_pos = tk.Label(self, text='Position :')
self.lbl_pos.grid(row=2, column=0)
self.entry_pos = tk.Entry(self, textvariable=self.position, width=5)
self.entry_pos.grid(row=2, column=1)
Here the code of the configuration frame, which has two 'MassConfig' frame inside.
import tkinter as tk
from gui.masse_config import MassConfig
class Configuration(tk.Frame):
def __init__(self, root, **kwargs):
tk.Frame.__init__(self, root, **kwargs)
self.root = root
self.grid()
self.update()
self.is_alive = True
self.data = {}
self.m1_frame = tk.LabelFrame(self, text='Masse 1', width=200, height=200)
self.m1_frame.grid(column=0, row=0, padx=(10, 5), pady=(10, 10))
self.m2_frame = tk.LabelFrame(self, text='Masse 2', width=200, height=200)
self.m2_frame.grid(column=1, row=0, padx=(5, 10), pady=(10, 10))
self.config_1 = MassConfig(self.m1_frame)
self.config_2 = MassConfig(self.m2_frame)
self.config_1.grid(padx=10, pady=10)
self.config_2.grid(padx=10, pady=10)
self.btn_validation = tk.Button(self, text='Valider', command=self.validation)
self.btn_validation.grid(row=3, column=1, padx=10, pady=(0, 10), sticky=tk.E)
self.update()
def validation(self):
print(":", self.config_1.position.get())
self.data['Mass 1'] = {}
self.data['Mass 1']['Position'] = self.config_1.position.get()
self.data['Mass 1']['Vitesse'] = self.config_1.vitesse.get()
self.data['Mass 1']['Masse'] = self.config_1.weight.get()
self.data['Mass 2'] = {}
self.data['Mass 2']['Position'] = self.config_2.position.get()
self.data['Mass 2']['Vitesse'] = self.config_2.vitesse.get()
self.data['Mass 2']['Masse'] = self.config_2.weight.get()
self.is_alive = False
self.root.destroy()
I want to have the value of the tkinter variables self.weight, self.vitesse and self.position from the MassConfig class in a dictionary (self.data from Configuration class). But nothing come out, except ''.
