crashes when using grid with ttk widgets - python

I need a specific layout for the gui I'm making with Tkinter/ttk on python 2.7, that's why I want to use the grid positioner to master my ttk widgets' relative positions. But everytime I run my code, nothing appears.
ps: I used some widgets with grid(), and some others with pack()
I don't know where's the problem! Here's the code:
from Tkinter import *
import ttk
master = Tk()
f4=Frame(master,width=300,height=300,bg="powder blue",relief=SUNKEN)
f4.pack(side=BOTTOM,fill=BOTH, expand=True)
test = True
f3=Frame(master,width=300,height=300,bg="red",relief=SUNKEN)
f3.pack(side=TOP,fill=BOTH, expand=True)
def create():
global test
if test:
global e
e = ttk.Entry(f4).grid(row=2,column=0, columnspan=2)
test = False
#e.focus_set()
def callback():
print e.get()
b = Button(master, text="get", width=10, command=callback)
b.grid(row=0, column=0)
c = Button(master, text="set", width=10, command=callback)
c.grid(row=0, column=1)
create()
mainloop()

Your problem is the use of pack() and grid() at the same time on the master window.
Use one or the other per container.
A container is the main root window, a Toplevel() window or a Frame.
Try something like this without pack():
from Tkinter import *
import ttk
master = Tk()
master.rowconfigure(0, weight=1)
master.columnconfigure(0, weight=1)
master.columnconfigure(1, weight=1)
f3=Frame(master,width=300,height=300,bg="red",relief=SUNKEN)
f3.grid(row=0, column=0, columnspan=2, sticky="nsew")
f4=Frame(master, width=300, height=300, bg="powder blue", relief=SUNKEN)
f4.grid(row=1, column=0, columnspan=2, sticky="nsew")
test = True
def create():
global test
if test:
global e
e = ttk.Entry(f4).grid(row=2,column=0, columnspan=2)
test = False
def callback():
print e.get()
b = Button(master, text="get", width=10, command=callback)
b.grid(row=2, column=0, sticky="e")
c = Button(master, text="set", width=10, command=callback)
c.grid(row=2, column=1, sticky="w")
create()
master.mainloop()
Here is a version just using pack().
I changed it up a little to give a different layout that might be closer to what you are trying.
from Tkinter import *
import ttk
master = Tk()
f3 = Frame(master, width=300, height=300, bg="red", relief=SUNKEN)
f3.pack(side=TOP, fill=BOTH, expand=True)
f4 = Frame(master, width=300, height=300, bg="powder blue", relief=SUNKEN)
f4.pack(side=TOP, fill=BOTH)
f5 = Frame(master, width=300)
f5.pack(side=BOTTOM, fill=BOTH)
test = True
def create():
global test
if test:
global e
e = ttk.Entry(f4).pack(side=TOP,fill=BOTH)
test = False
def callback():
print e.get()
b = Button(f5, text="get", width=10, command=callback)
b.pack(side=LEFT, fill=BOTH, expand=True)
c = Button(f5, text="set", width=10, command=callback)
c.pack(side=RIGHT, fill=BOTH, expand=True)
create()
master.mainloop()

OOP based tkinter

I want button 1 on to the second frame
from tkinter import *
root =Tk()
class Graphic():
def __init__(self, master):
self.colour = "blue"
self.frame_input = Frame(master, height =100, width=100, bg="green").grid(row=0, column=0)
self.label_process = Label(master, width=30).grid(row=1, column=0)
self.frame_button = Frame(master,height=100,width=100, bg="red").grid(row=2, column=0)
self.button = Button(master, text="1", bg=self.colour).grid(row=0, column=0)
if '__main__' == __name__:
grafic = Graphic(root)
root.mainloop()
The first argument for each widget is the parent to attach to. You told it to attach to master, and it did. If you want it attached to the second frame, change:
self.button = Button(master, text="1", bg=self.colour).grid(row=0, column=0)
to:
self.button = Button(self.frame_button, text="1", bg=self.colour)
self.button.grid(row=0, column=0)
Note, this still doesn't work, because you tried to chain your grid calls, and grid returns None, so all your attributes (including self.frame_button) are None, not widgets. To fix, split the creation and layout steps for all your widgets:
self.frame_input = Frame(master, height =100, width=100, bg="green")
self.frame_input.grid(row=0, column=0)
self.label_process = Label(master, width=30)
self.label_process.grid(row=1, column=0)
self.frame_button = Frame(master,height=100,width=100, bg="red")
self.frame_button.grid(row=2, column=0)
self.button = Button(self.frame_button, text="1", bg=self.colour)
self.button.grid(row=0, column=0)

run commands on a split frame in the main window using tkinter

I'm new to tkinter and i've built this so far:
import tkinter as tk
import subprocess
import os
def maingui():
window = tk.Tk()
window.title("My first GUI")
#window.state('zoomed')
window.geometry("700x205")
window.configure(bg="black")
frame1 = tk.Frame(window, width=90, bg="orange")
# frame1.pack(fill=tk.Y, side=tk.LEFT)
frame1.grid(row=0, column=0)
frame2 = tk.Frame(window, width=1890, bg="black")
# frame2.pack(fill=tk.Y, side=tk.RIGHT)
frame2.grid(row=0, column=1)
lotomat = tk.Button(frame1, text=" Start\n Lotomat", padx=10, pady=5, bg="orange", fg="black",
relief=tk.GROOVE, command=lambda : startLotomat())
# lotomat.pack()
lotomat.grid(row=1, column=0)
convert = tk.Button(frame1, text=" URL2IP \n on \n Desktop", padx=10, pady=5, bg="orange", fg="black",
relief=tk.GROOVE, command=lambda : startURL2IP())
# convert.pack()
convert.grid(row=2, column=0)
startRps = tk.Button(frame1, text=" Start \nR.P.S", padx=12, pady=5, bg="orange", fg="black",
relief=tk.GROOVE, command=lambda : startRPS())
# startRps.pack()
startRps.grid(row=3, column=0)
endRun = tk.Button(frame1, text="Quit", padx=12, pady=10, bg="orange", fg="black",
relief=tk.RIDGE, command=lambda : ending())
# endRun.pack()
endRun.grid(row=4, column=0)
def startLotomat():
os.system('python lotomat.py')
def startURL2IP():
os.system('python urltoipondesktop.py')
def startRPS():
os.system('python rockpaperscissors.py')
def ending():
exit()
window.mainloop()
maingui()
each button runs a different .py file.
how can I use frames to split the window so the program runs on the right side?
Thanks!
Edit:
I've added a pic of the GUI, the goal is to run the left menu buttons on the black frame.
Following acw1668's comment and alot of thread researching here's the thread solution. so elegant, so simple! I love python!
def thread_handler(self, host):
wt = threading.Thread(target=self.write_to_file, args=(host,))
pt = threading.Thread(target=self.print_to_box, args=(host,))
dt = threading.Thread(target=self.delete_default_lines, args=())
wt.start()
pt.start()
dt.start()

Python Tkitner : unknown option "-height". Can't change the size of button

I am trying to make a simple program using tkinter.
I was trying to change font or style of width or height.
width can be changed but when it comes to height or font - it shows mistake.
I am thinking - maybe it can be because the layout?
(The button that is changed in width is in the bottom of def initUI)
Also in case anyone can also answer this question:
I made 1 frame red because there will be error messages there but does anyone know how to make this red lie less in width?
Thank you in

This is one of the prime examples of why global imports are bad.
You write at the top:
from tkinter import *
from tkinter.ttk import *
This means that you import everything from tkinter and tkinter.ttk into your main.py namespace. Then you write for example:
frame3 = Frame(self, bg="grey")
....
lblCol = Label(frame2, text="Column", width=7)
These are Frame/Label objects, but which ones? The one in tkinter or the one in tkinter.ttk? If it is the first, you will have to set the height with -height, else you will have to use tkinter.ttk.Style(). Same with the -bg for the frame.
Solution:
import tkinter as tk
class Example(tk.Frame):
def __init__(self,master):
super().__init__()
master.minsize(width=350, height=160)
master.maxsize(width=650, height=500)
self.initUI()
def initUI(self):
self.master.title("Hank (version 3)")
self.pack(fill=tk.BOTH, expand=True)
frame1 = tk.Frame(self)
frame1.pack(fill=tk.X)
#dataset
lbl1 = tk.Label(frame1, text="Dataset file_name", width=18)
lbl1.pack(side=tk.LEFT, padx=5, pady=5)
entryDataset= tk.Entry(frame1)
entryDataset.pack(fill=tk.X, padx=5, expand=True)
#row col begin
frame2 = tk.Frame(self)
frame2.pack(fill=tk.X)
lblRow = tk.Label(frame2, text="Row", width=6)
lblRow.pack(side=tk.LEFT, padx=5, pady=5)
entryRow = tk.Entry(frame2, width=5)
entryRow.pack(side=tk.LEFT, padx=0, expand=True)
lblCol = tk.Label(frame2, text="Column", width=7)
lblCol.pack(side=tk.LEFT, padx=5, pady=5)
entryCol = tk.Entry(frame2, width=5)
entryCol.pack(side=tk.LEFT, padx=5, expand=True)
lblBegin = tk.Label(frame2, text="Start at", width=6)
lblBegin.pack(side=tk.LEFT, padx=5, pady=5)
entryBegin = tk.Entry(frame2, width=5)
entryBegin.pack(side=tk.LEFT, padx=0, expand=True)
frame3 = tk.Frame(self, bg="grey")
frame3.pack(fill=tk.BOTH, expand=True)
frame4 = tk.Frame(self)
frame4.pack(fill=tk.BOTH, expand=True)
startbutton = tk.Button(frame4, text="Start Clustering", height="100", width="100")
startbutton.pack(side=tk.RIGHT, padx=5, pady=5)
def main():
root = tk.Tk()
root.geometry("300x160+300+160")

I did it here with the tkinter widgets. You can obviously do import tkinter.ttk as ttk and rewrite the code using those, it is just a matter of taste.

iconify in tkinter in python

I have written a code in python 2.7 and i have created a root window with two buttons: submit and cancel when i press submit button, a new window opens and previous parent/root window gets iconify. Now i want that when i cut the child window, parent window should be deiconify, i am in a trouble that where to put the condition so that parent window gets deiconify?
from Tkinter import *
root = Tk()
root.title("test window")
root.geometry('400x220+500+250')
root.configure(background="dark gray")
def submit(*args):
root.iconify()
popup_root_window = Toplevel()
popup_root_window.geometry('300x50+550+300')
popup_root_window.resizable(width=False, height=False)
popup_root_window.focus_force()
popup_root_window.grab_set()
popup_root_window_label = Label(popup_root_window, text="new window open successfully.")
popup_root_window_label.pack(anchor=CENTER, padx=10, pady=20)
frame = Frame(root, bd=4, relief="raise", height=100, width=250)
frame.pack(fill="both", padx=70, pady=35)
frame.pack_propagate(0)
submit_button = Button(frame, text="Submit", command=submit, width=10)
submit_button.grid(row=0, column=0)
cancel_button = Button(frame, text="Cancel", width=10)
cancel_button.grid(row=0, column=1)
root.mainloop()
I wrote the below in 3.6 but it should still work in 2.7.
from tkinter import *
class App:
def __init__(self, root):
self.root = root
self.label1 = Label(self.root, text="I'm your main window.")
self.button = Button(self.root, text="Submit", command=self.command)
self.label1.pack()
self.button.pack()
def command(self):
self.root.iconify()
self.top = Toplevel(self.root)
self.label2 = Label(self.top, text="I'm your toplevel window.")
self.label2.pack()
self.top.protocol("WM_DELETE_WINDOW", self.close)
def close(self):
self.top.destroy()
self.root.deiconify()
root = Tk()
App(root)
root.mainloop()
You can use .protocol() on the event WM_DELETE_WINDOW to create a callback whenever the X is selected from the title bar of the designated window.
This is tested and working with Python 3.6 on Windows 10.
You can try this one. i have tested this in python 2.7.13 and it working correctly.
from Tkinter import *
root = Tk()
root.title("test window")
root.geometry('400x220+500+250')
root.configure(background="dark gray")
def submit(*args):
def on_closing(*args):
popup_root_window.destroy()
root.deiconify()
root.iconify()
popup_root_window = Toplevel()
popup_root_window.geometry('300x50+550+300')
popup_root_window.resizable(width=False, height=False)
popup_root_window.focus_force()
popup_root_window.grab_set()
popup_root_window_label = Label(popup_root_window, text="new window open successfully.")
popup_root_window_label.pack(anchor=CENTER, padx=10, pady=20)
popup_root_window.protocol("WM_DELETE_WINDOW", on_closing)
frame = Frame(root, bd=4, relief="raise", height=100, width=250)
frame.pack(fill="both", padx=70, pady=35)
frame.pack_propagate(0)
submit_button = Button(frame, text="Submit", command=submit, width=10)
submit_button.grid(row=0, column=0)
cancel_button = Button(frame, text="Cancel", width=10)
cancel_button.grid(row=0, column=1)
root.mainloop()

why is nothing returned when I invoke .get()

Having trouble setting the file path that is selected by the user and setting to variable. I am able to retrieve the path and set it to display in the entry box but I would like to capture that path and import it into another script. Maybe my logic is flawed here? What am I doing wrong?
import Tkinter
import tkFileDialog
from Tkinter import *
from tkFileDialog import *
class GUI:
def __init__(self, master):
self.master = master
master.title("XML Compare Tool")
master.geometry('700x300')
path1 = StringVar()
path2 = StringVar()
self.bb1 = Button(master, text="Browse", command=lambda: path1.set(askopenfilename()))
self.bb1.grid(row=0, column=0, padx=5, pady=5)
self.bb2 = Button(master, text="Browse", command=lambda: path2.set(askopenfilename()))
self.bb2.grid(row=1, column=0, padx=5, pady=5)
self.confirm = Button(master, text="Confirm", command='')
self.confirm.grid(row=3, column=1, padx=5, pady=5, sticky='')
self.entry1 = Entry(master, width=75, textvariable=path1)
self.entry1.grid(row=0, column=1, columnspan=2, sticky=W)
print path1.get()
self.entry2 = Entry(master, width=75, textvariable=path2)
self.entry2.grid(row=1, column=1, sticky=W)
self.t_label = Label(master, text="Script Output")
self.t_label.grid(row=4, column=1, columnspan=1, sticky='')
self.t_frame = Frame(master, bg="white", height=150, width=600)
self.t_frame.grid(row=5, column=1, columnspan=1, sticky='')
self.t_text = Text(self.t_frame)
root = Tk()
my_gui = GUI(root)
root.mainloop()
You do not need to use a textvariable, you can just use variable = entry1.get(). A Tkinter textvariable is not like a traditional python variable, it is just used for setting the text in an entry.
