Getting multiple results with one button (python/ tkiner) - python

I'm a beginner, and I've gathered a number of reference sites to make code!
But if you click the button, you'll see the value only for the last item.
Do you happen to know how to get each result in every row! And now you have to enter all the items to get the value, but even if there is a blank, I hope the result will come out for all the input boxes.
I think the code is a little tangled, but it's hard to solve. I'm posting the code's full text.

tkinter clickable Label to open details of Label [duplicate]

This question already has answers here:
tkinter creating buttons in for loop passing command arguments
(3 answers)
Closed 6 months ago.
I'm trying to program an interface with tkinter, that shows users of my application as a list of Labels. The list is created from a database (created with sqlite3).
By clicking on each Label the program should open another window, showing details of the clicked user.
maybe do I need to use classes? (because for now, my script is not OOP)
root = Tk()
root.title("Utenti")
root.iconbitmap("D:\Willow\WilloW SW Gestionale")
root.geometry("365x600")

user.title("Utenti")
user.iconbitmap("D:\Willow\WilloW SW Gestionale")
user.geometry("500x400")

here is the section i am confused about and would like some help with.

if int(self.Total_Maccas_num) > 5:
self.TooMany.grid(row=20, column=1)
else:
self.Total_Maccas_num(row=20, column=1)
if anyone can solve this problem it would help a lot thanks.

Inside Maccas_Submit(), you have changed self.Total_Maccas_num from IntVar (initialized inside init_window()) to int:
def Maccas_Submit(self):
# below line changed self.Total_Maccas_num to 'int'
self.Total_Maccas_num = int(self.BigMac_num.get()) + int(self.Nuggets_num.get()) + int(self.AngusBurger_num.get()) + int(self.Wraps_num.get()) + int(self.SoftServe_num.get()) + int(self.Fillet_o_Fish_num.get()) + int(self.HappyMeal_num.get()) + int(self.Salad_num.get()) + int(self.Sprite_num.get()) + int(self.Frozen_Coke_num.get()) + int(self.Apple_Pie_num.get()) + int(self.Apple_Slices_num.get())
if int(self.Total_Maccas_num) > 5:
self.TooMany.grid(row=20, column=1)
else:
# below line tries to use 'int' as a function which causes the exception
self.Total_Maccas_num(row=20, column=1)
Based on your code, I would suggest the following changes:
class Window(Frame):
...
def init_window(self):
...
self.Total_Maccas_num = IntVar()
Button(self, text='Finish Order',fg='#27251F',bg='#DA291C', command=self.Maccas_Submit).grid(row=16, column=0, sticky=W, pady=4, padx=5)
self.TooMany = Label(self, text = "Less than 5 items please.")
#self.TooMany.grid_remove() # not necessary
self.total_label = Label(self, textvariable=self.Total_Maccas_num) # added a label for the total
def Maccas_Submit(self):
total = int(self.BigMac_num.get()) + int(self.Nuggets_num.get()) + int(self.AngusBurger_num.get()) + int(self.Wraps_num.get()) + int(self.SoftServe_num.get()) + int(self.Fillet_o_Fish_num.get()) + int(self.HappyMeal_num.get()) + int(self.Salad_num.get()) + int(self.Sprite_num.get()) + int(self.Frozen_Coke_num.get()) + int(self.Apple_Pie_num.get()) + int(self.Apple_Slices_num.get())
if total > 5:
self.total_label.grid_forget() # hide the total_label
self.TooMany.grid(row=20, column=1) # show the warning
else:
self.TooMany.grid_forget() # hide the warning
self.Total_Maccas_num.set(total) # update total_label
self.total_label.grid(row=20, column=1) # show total_label

Python Tkinter, How to pass Variable into mutltiple Functions

EDIT: Thanks to #Osadhi Virochana Jayasinghe Si! Using global "vars" inside the buildwindow() function, makes them readable in the called button function. I also had to fix how to get the Values of the Checkbox and text Widget.
Full Fixed code:
import tkinter as tk
import tkinter.scrolledtext as tkst
from PyQt5.QtWidgets import QApplication # need to install PyQt5 or remove center() Function
def main_window():
window = tk.Tk()
window.title("New Entry")
build_window(window)
center(window) # https://stackoverflow.com/questions/3352918/how-to-center-a-window-on-the-screen-in-tkinter
window.mainloop() # Main Loop, nothing runs after here on Gui
def center(toplevel):
toplevel.update_idletasks()
app = QApplication([])
screen_width = app.desktop().screenGeometry().width()
screen_height = app.desktop().screenGeometry().height()
size = tuple(int(_) for _ in toplevel.geometry().split('+')[0].split('x'))
x = screen_width/2 - size[0]/2
y = screen_height/2 - size[1]/2
toplevel.geometry("+%d+%d" % (x, y))
def build_window(window):
global entry_name, entry_link, entry_xpath, chbox_active, entry_comment, box_var

label_link = tk.Label(window, text="Link:")
entry_link = tk.Entry(window)
label_xpath = tk.Label(window, text="XPath:")
entry_xpath = tk.Entry(window)
label_active = tk.Label(window, text="Active:")
box_var = tk.IntVar()
chbox_active = tk.Checkbutton(window, variable=box_var, text="Active")
label_comment = tk.Label(window, text="Comment:")
entry_comment = tkst.ScrolledText(window, width=40, height=4, font=("roboto", 8))

I am trying to make a simple GUI do enter Data into a Dictionary. Most things i find online write the Tkinter straight into the .py, but i want to use a Function to Draw the Window, and another Function to do its stuff once a Button is pressed.
Shorted code:
def main_window():
window = tk.Tk()
build_window(window)
window.mainloop()
def build_window(window):
entry_name = tk.Entry(window)
button_go = tk.Button(window, text="Run", command=lambda: write_dict())
button_go.grid(row=7, column=1, sticky="e", padx=2, pady=2)
def write_dict():
i_dict = {}
i_dict["name"] = entry_name.get()
main_window()
And i am getting AttributeError: module 'tkinter' has no attribute 'entry_name'. I tried various ways to get window into write_dict(), but i could never use .get() to read the values inside the Entry Box.
how would i do this?

Add global entry_name,entry_link,entry_xpath,chbox_active,entry_comment under the def build_window(window): It will fix Variable error.
And I fixed all of the issues
Here is the Code:
import tkinter as tk
import tkinter.scrolledtext as tkst
#from PyQt5.QtWidgets import QApplication
d_list = []
def main_window():
window = tk.Tk()
window.title("New Entry")
build_window(window)
window.mainloop() # Main Loop, nothing runs after here on Gui
def build_window(window):
global entry_name,entry_link,entry_xpath,chbox_active,entry_comment,var
var = tk.IntVar()
label_title = tk.Label(window, text="NEW ENTRY")
label_name = tk.Label(window, text="Name:")
entry_name = tk.Entry(window)
label_link = tk.Label(window, text="Link:")
entry_link = tk.Entry(window)
label_xpath = tk.Label(window, text="XPath:")
entry_xpath = tk.Entry(window)
label_active = tk.Label(window, text="Active:")
chbox_active = tk.Checkbutton(window, variable=var, text="Active")
label_comment = tk.Label(window, text="Comment:")
entry_comment = tkst.ScrolledText(window, width=40, height=4, font=("roboto", 8))
botton_cancel = tk.Button(window, text="Done", command=lambda: close_window(window))
button_go = tk.Button(window, text="Run", command=lambda: write_dict())
label_title.grid (row=0, column=1, sticky="nwse", padx=2, pady=2)
label_name.grid (row=1, column=0, sticky="e", padx=2, pady=2)
entry_name.grid (row=1, column=1, sticky="nwse", padx=2, pady=2)
label_link.grid (row=2, column=0, sticky="e", padx=2, pady=2)
entry_link.grid (row=2, column=1, sticky="nwse", padx=2, pady=2)

label_active.grid (row=4, column=0, sticky="e", padx=2, pady=2)
chbox_active.grid (row=4, column=1, sticky="w", padx=2, pady=2)
label_comment.grid (row=5, column=0, sticky="e", padx=2, pady=2)

def close_window(window):
window.destroy()
def write_dict():
global d_list
i_dict = {}
v = ""
i_dict["name"] = entry_name.get()
i_dict["link"] = entry_link.get()
i_dict["xpath"] = entry_xpath.get()
i_dict["active"] = var.get()
i_dict["comment"] = entry_comment.get('1.0', 'end-1c')
print(i_dict)
pass
main_window()
Now you can get checkbox status and comment box status too.

hit run. you will see results of second player beside first player values.

This will fetch numbers from csv row for specific player. Am placing the value beside value names in the GUI.
Hope this helps.

Python tkinter, clearing an Entry widget from a class

This is the class I'm calling and the function from a different file
class CalcFunc:
def clearScreen(self):
self.log("CLEAR (CE)")
ent.delete(0, END)
This is the Entry Box
ent = Entry(root, textvariable=clc.getBtn, justify=RIGHT, font=10, relief=RIDGE, bd=2, width=15)
ent.grid(row=0, columnspan=3, pady=10)
This is the button I'm clicking to clear the Entry Box
buttonCC = Button(root, text="CLEAR (CE)", height=1, width=20, bg='orange', command=clc.clearScreen)
I'm not sure what the syntax is to be able to to clear an Entry widget from a class basically. That code worked when I had it in the same file but my project requires it to be in a separate file. It's a class project for a calculator and the "clear" button clears the Entry widget. I can post my entire code if that helps. Thank you.
----EDIT----
My Class
import time
class CalcFunc:
def log(self, val):
myFile = open(r".\log.dat", "a")
myFile.write("%s\n" % val)
myFile.close()
def onScreen(self, iVal):
self.log(iVal)
currentTxt = self.getBtn.get()
updateEnt = self.getBtn.set(currentTxt + iVal)
def clearScreen(self):
self.log("CLEAR (CE)")
ent.delete(0, END)
def evaL(self):
self.log("=")
self.getBtn.set(str(eval(self.getBtn.get())))
self.log(self.getBtn.get())
def logLbl(self):
myFile = open(r".\log.dat", "a")

ent = Entry(root, ....)
clc = clcClass.CalcFunc(ent)
class CalcFunc:
def __init__(self, entry):
self.entry = entry
def clearScreen(self):
self.log("CLEAR (CE)")
self.entry.delete(0, END)
Here's an abbreviated example:
#my_entry.py
from tkinter import END
import time
class EntryWithLogger:
def __init__(self, entry):
self.entry = entry
def log(self, val):
with open("log.dat", "a") as my_file: #Automatically closes the file--even if an exception occurs, which is not the case with my_file.close().
my_file.write("%s\n" % val)
def onScreen(self, i_val):
self.log(i_val)
self.entry.insert(END, i_val)
def clearScreen(self):
self.log("CLEAR (CE)")
self.entry.delete(0, END)
Note that I didn't use a StringVar(), which doesn't appear to be necessary. If you need it, you can always pass it as an argument to __init__(), then store it on self.
import my_entry as me
import tkinter as tk
root = tk.Tk()
root.title("Calculator")
root.geometry("+100+50") #("300x500+200+10") dimension, position
entry = tk.Entry(root, justify=tk.RIGHT, font=10, relief=tk.RIDGE, bd=2, width=15)
entry.grid(row=0, columnspan=3, pady=10)
entry_with_logger = me.EntryWithLogger(entry)
#Create the buttons in a loop:
for i in range(10):
row_num, col_num = divmod(i, 3) #divmod(7, 2) => (3, 1), divmod(0, 3) => (0, 0), divmod(4, 3) => (1, 1)
row_num += 1
button_text = str(i)
tk.Button(root, text=button_text,
height=1,
width=5,
bg='light blue',
command=lambda x=button_text: entry_with_logger.onScreen(x)
).grid(row=row_num, column=col_num, pady=5)
#Put the clear button at the bottom of the grid:
tk.Button(root, text="CLEAR (CE)",
height=1,
width=20,
bg='orange',
command=entry_with_logger.clearScreen
).grid(row=row_num+1, columnspan=3) #columnspan tells grid() to use 3 cells for the button,
#and the button will be centered by default.
root.mainloop()
Or, you could do it like this:
#my_entry.py
from tkinter import Entry, END
import time
class EntryWithLogger(Entry):
#Because __init__() is not implemented, the parent class's __init__() gets
#called, so you create an EntryWithLogger just like you would an Entry.
def log(self, val):
with open("log.dat", "a") as my_file: #Automatically closes the file--even if there is an exception, which is not the case with my_file.close().
my_file.write("%s\n" % val)
def onScreen(self, i_val):
self.log(i_val)
self.insert(END, i_val)
def clearScreen(self):
self.log("CLEAR (CE)")
self.delete(0, END)
