I have a program that uses Tkinter and I'm trying to assign a command to a button in my root window that opens one additional window. I'm using Toplevel(), but whenever I click the button I've assigned the command to, two windows open, one with my root window's name and one with the name of the additional window I've assigned.
I've tried using .withdraw and .destroy, to hide or remove this extra root window, but nothing seems to be working.
Here is my code:
import Tkinter
from Tkinter import *
root = Tk()
root.wm_title("VACS")
# # Top label # #
SetParameters = Label(text="Set Parameters", width=110, relief=RIDGE)
SetParameters.grid(row=1, column=0, columnspan=7, padx=5, pady=5)
# # Spatial freq settings # #
SpatialFreq = Label(text="Spatial Frequency", width=15, relief=RIDGE)
SpatialFreq.grid(row=3, column=0, padx=5, pady=5)
From1 = Label(text="from")
From1.grid(row=3, column=1, padx=5, pady=5)
Select1 = Spinbox(from_=0, to=10, width=25)
Select1.grid(row=3, column=2, padx=5, pady=5)
To1 = Label(text="to")
To1.grid(row=3, column=3, padx=5, pady=5)
Select2 = Spinbox(from_=0, to=10, width=25)
Select2.grid(row=3, column=4, padx=5, pady=5)
Steps = Label(text="in steps of")
Steps.grid(row=3, column=5, padx=5, pady=5)
Select3 = Spinbox(from_=0, to=10, width=25)
Select3.grid(row=3, column=6, padx=5, pady=5)
# # Contrast settings # #
Contrast = Label(text="Contrast", width=15, relief=RIDGE)
Contrast.grid(row=5, column=0, padx=5, pady=5)
From2 = Label(text="from")
From2.grid(row=5, column=1, padx=5, pady=5)
Select4 = Spinbox(from_=0, to=10, width=25)
Select4.grid(row=5, column=2, padx=5, pady=5)
To2 = Label(text="to")
To2.grid(row=5, column=3, padx=5, pady=5)
Select5 = Spinbox(from_=0, to=10, width=25)
Select5.grid(row=5, column=4, padx=5, pady=5)
Steps2 = Label(text="in steps of")
Steps2.grid(row=5, column=5, padx=5, pady=5)
Select6 = Spinbox(from_=0, to=10, width=25)
Select6.grid(row=5, column=6, padx=5, pady=5)
# # Test button # #
Test = Button(text="Begin Test", width=25, command=Top)
Test.grid(row=6, column=0, columnspan=7, pady=5)
# # Directory input window # #
def Top():
Toplevel()
Toplevel().wm_title("Directory")
root.mainloop()
If you click "Begin Test" in the root window, two extras pop up. I only want the one that says "Directory."
Any ideas?
You're creating two, since Toplevel() is the constructor call:
Toplevel()
Toplevel().wm_title("Directory")
Instead, create one and save it:
top = Toplevel()
top.wm_title("Directory")

The following code
root = tk.Tk()
frame = ttk.Frame(root, padding=10)
frame.grid()
# Browse
tk.Text(frame, state="disabled", height=1).grid(column=0, row=0, columnspan=3, sticky="W", pady=5, ipadx=2, ipady=2)
ttk.Button(frame, text="Browse", command=None).grid(column=3, row=0, sticky="E")
# Selected files
tk.Text(frame, state="disabled").grid(column=0, row=1, columnspan=4, sticky="EW", pady=10)
# Options
ttk.Button(frame, text="SELECT", command=None).grid(column=0, row=2, sticky="W")
ttk.Button(frame, text="DELETE", command=None).grid(column=1, row=2, sticky="W")
ttk.Button(frame, text="Merge", command=None).grid(column=2, row=2, sticky="W")
ttk.Button(frame, text="Close", command=root.destroy).grid(column=3, row=2, sticky="E")
root.mainloop()
produces this,
but I want the DELETE and MERGE buttons to be left-aligned so they are together with the SELECT button. How can I achieve this?
Put buttons in new Frame and this frame put in original Frame
buttons_frame = ttk.Frame(frame)
buttons_frame.grid(column=0, row=2, sticky="W")
ttk.Button(buttons_frame, text="SELECT", command=None).grid(column=0, row=2, sticky="W")
ttk.Button(buttons_frame, text="DELETE", command=None).grid(column=1, row=2, sticky="W")
ttk.Button(buttons_frame, text="Merge", command=None).grid(column=2, row=2, sticky="W")
BTW:
In buttons_frame you may even use .pack(side='left') instead of grid()
Full code:
import tkinter as tk
import tkinter.ttk as ttk
root = tk.Tk()
frame = ttk.Frame(root, padding=10)
frame.grid()
# Browse
tk.Text(frame, state="disabled", height=1).grid(column=0, row=0, columnspan=3, sticky="W", pady=5, ipadx=2, ipady=2)
ttk.Button(frame, text="Browse", command=None).grid(column=3, row=0, sticky="E")
# Selected files
tk.Text(frame, state="disabled").grid(column=0, row=1, columnspan=4, sticky="EW", pady=10)
# Options
buttons_frame = ttk.Frame(frame)
buttons_frame.grid(column=0, row=2, sticky="W")
ttk.Button(buttons_frame, text="SELECT", command=None).grid(column=0, row=2, sticky="W")
ttk.Button(buttons_frame, text="DELETE", command=None).grid(column=1, row=2, sticky="W")
ttk.Button(buttons_frame, text="Merge", command=None).grid(column=2, row=2, sticky="W")
ttk.Button(frame, text="Close", command=root.destroy).grid(column=3, row=2, sticky="E")
root.mainloop()
EDIT:
You may also add empy column between Merge and Close and assign weight=1 to this column so it will get all empty space.
It needs to move Browse and Close to next column, and increase columnspan in both Text
import tkinter as tk
import tkinter.ttk as ttk
root = tk.Tk()
frame = ttk.Frame(root, padding=10)
frame.grid()
frame.columnconfigure(3, weight=1) # column 3 will use all free space
# Browse
tk.Text(frame, state="disabled", height=1).grid(column=0, row=0, columnspan=4, sticky="W", pady=5, ipadx=2, ipady=2)
ttk.Button(frame, text="Browse", command=None).grid(column=4, row=0, sticky="E")
# Selected files
tk.Text(frame, state="disabled").grid(column=0, row=1, columnspan=5, sticky="EW", pady=10)
# Options
ttk.Button(frame, text="SELECT", command=None).grid(column=0, row=2, sticky="W")
ttk.Button(frame, text="DELETE", command=None).grid(column=1, row=2, sticky="W")
ttk.Button(frame, text="Merge", command=None).grid(column=2, row=2, sticky="W")
ttk.Button(frame, text="Close", command=root.destroy).grid(column=4, row=2, sticky="E")

Can someone help, i need to generate 10 buttons and then when i click it must change the text on the unnamed button.
trying to get the event.widget but with no successes
from tkinter import ttk
root = ttk()
def gonow(e):
e.config(text="clicked")
for x in range(0, 10):
ttk.Button(root, name="but"+x,width="30", height=3, text=x).grid( column=0,
r.ow=0, padx=10, pady=5)
butok=ttk.Button(root, width="30", height=3, text=x, command=lambda var="but"+x:

b.grid(column=colcount, row=rowcount, padx=10, pady=5)
buttonslst.append(b)
valbut=int(assumirrowr)-8
print(valbut)
print(buttonslst[valbut])
fvarbut=buttonslst[valbut]
print(fvarbut)
ttk.Button(frm_but_oknot, width="15", text="OK", image=photoOK, command=lambda assumirrow=assumirrow,filename=filename_report,exp=lblexpect,obs=resp_kiblog,urrrl=url_conf,tipo_de_conf=tipo_de_conf, resp_json_input=resp_json_input, reqst_input=reqst_input: savetoxls("geradorteste",resp_json_input,reqst_input, "OK",tipo_de_conf,urrrl,obs,exp,filename,assumirrow,fvarbut)).grid( column=0, row=0, padx=1, pady=15)
When you pass x to gonow, it is the index of the button, not the button itself. You could store the buttons in a list (note: the buttons, not the result of grid!), and then use the index:
buttons = []
for x in range(0, 3):
b = tk.Button(root, width=30, height=3, text=x, command=lambda x=x: gonow(buttons[x]))
b.grid(column=0, row=x, padx=10, pady=5)
buttons.append(b)
Or postpone the command creation after the button is created and pass the button itself:
for x in range(0, 3):
b = tk.Button(root, width=30, height=3, text=x)
b.config(command=lambda b=b: gonow(b))
b.grid(column=0, row=x, padx=10, pady=5)
(Note: There are a few more unrelated (syntax) errors throughout your code that you should fix.)
If Info is blank, then the Entry Field and Button are at the red vertical line. But if Info has text, then they shift to the right. How can I fix the positions of the Entry Field and Button? Thanks.
window = Toplevel()
window.geometry('400x400')
searchL = Label(window, text='Enter ID:')
searchL.grid(row=0, column=0, padx=10, pady=10)
searchE = Entry(window)
searchE.grid(row=0, column=1, padx=10, pady=10)
def searchEmp():
for e in listOfEmployees:
if e.i == searchE.get():
results.set(repr(e))
search = Button(window, text='Search', command=searchEmp)
search.grid(row=1, column=0, columnspan=2)
infoL = Label(window, text='Info:')
infoL.grid(row=2, column=0, padx=10, pady=10)
results = StringVar()
resultsL = Label(window, textvariable=results)
resultsL.grid(row=2, column=1, padx=10, pady=10)
Adding the sticky arg fixed it for this Entry Field.
searchE.grid(row=0, column=1, padx=10, pady=10, **sticky=W**)
For the Search button, columnspan was set to 2, so if I removed columnspan, set the column=2, and added sticky=W, it worked.
Thanks to stovfl for the link.
I have a Toplevel Window with one grid row containing a Label, Entry and a "+" Button (window on startup)
When I hit the Add-Button a new row with the same content is generated. But the problem is, that the window doesn't resize and fit to its new contents. Should look like this resized window.
The code is below:
def process_map():
numbers = {0:'\u2080', 1:'\u2081', 2:'\u2082', 3:'\u2083', 4:'\u2084', 5:'\u2085', 6:'\u2086', 7:'\u2087', 8:'\u2088', 9:'\u2089'}
button_pos = tk.IntVar(0)
ENTRIES = {}
def add_button():
if button_pos.get() >= 10:
index = numbers[button_pos.get()//10] + numbers[button_pos.get()%10]
else:
index = numbers[button_pos.get()]
lb = tk.Label(top_root, text='\u03C6'+index)
lb.grid(row=button_pos.get(), column=0, sticky='NWES')
entry = tk.Entry(top_root, width=4, relief='sunken', bd=2)
entry.grid(row=button_pos.get(), column=1, sticky='WE', padx=5, pady=5)

I have created a window with a button saying Enter, when clicked I would like it to proceed to an options menu with 3 separate sliders whereby the user can adjust them to get a value then press enter. With this value I would like to have a timed output that is the same as that value in seconds. I am very new to Python and need as much help as possible please :)
This is my code so far; and so far the first enter screen will appear then when the enter button is pressed it will load the next window I have created with the three sliders inside it I am not sure this is the best way to do it? Complete novis!
Please Advise :)
