I want to put another Frame in ttk.Notebook(), I use ttk.Frame() to do that.
Because tk.Frame() can't put multiple frame in ttk.Notebook().
Code:
import tkinter as tk
import tkinter.ttk as ttk
def Notebook(root: tk.Tk) -> tk.Frame:
notebook=ttk.Notebook(root)
f1 = tk.Frame()
f2 = tk.Frame()
notebook.add(f1, text="First")
notebook.add(f2, text="Second")
notebook.pack(padx=10, pady=10, fill='both', expand=True)
return f1
def ttkFrame(frame: tk.Frame) -> ttk.Frame:
f = ttk.Frame(frame, width=200, height=100)
ttk.Style().configure('TFrame', background='#DCB5FF')
f.grid(row=0, column=0)
return f
if __name__ == "__main__":
root = tk.Tk()
root.configure(bg="#7AFEC6")
root.geometry('400x600')
f1 = Notebook(root)
ttk_f1 = ttkFrame(f1)
root.mainloop()
Then put an entry or something element in ttk.Frame by grid(), that will be change ttk.Frame() size.
def use_entry(farme: ttk.Frame) -> None:
entry = tk.Entry(farme, width=20)
entry.insert(0, "Hello World")
entry.grid(row=0, column=0)
if __name__ == "__main__":
root = tk.Tk()
root.configure(bg="#7AFEC6")
root.geometry('400x600')
f1 = Notebook(root)
ttk_f1 = ttkFrame(f1)
use_entry(ttk_f1)
root.mainloop()
I know can use grid_rowconfigure(some args) and grid_columnconfigure(some args) to maintain size.
But I want to know why happend that?

I am making this PDF tool, and I want the buttons to be disabled until a file or files are successfully imported. This is what the app looks like at the launch:
Right after running the callback for the import files button, the active state looks like this:
I want the colors of the buttons to turn maroon instead of the original grey. They only turn back to maroon once you hover the mouse over them. Any thoughts for how to fix this? Here is the callback for the import button:
def import_callback():
no_files_selected = False
global files
files = []
try:
ocr_button['state'] = DISABLED
merge_button['state'] = DISABLED
status_label.pack_forget()
frame.pack_forget()
files = filedialog.askopenfilenames()
for f in files:
name, extension = os.path.splitext(f)
if extension != '.pdf':
raise
if not files:
no_files_selected = True
raise
if frame.winfo_children():
for label in frame.winfo_children():
label.destroy()
make_import_file_labels(files)
frame.pack()
ocr_button['state'] = ACTIVE
merge_button['state'] = ACTIVE
except:
if no_files_selected:
status_label.config(text='No files selected.', fg='blue')
else:
status_label.config(text='Error: One or more files is not a PDF.', fg='red')
status_label.pack(expand='yes')
import_button = Button(root, text='Import Files', width=scaled(20), bg='#5D1725', bd=0, fg='white', relief='groove',
command=import_callback)
import_button.pack(pady=scaled(50))
I know this was asked quite a while ago, so probably already solved for the user. But since I had the exact same problem and do not see the "simplest" answer here, I thought I would post:
Just change the state from "active" to "normal"
ocr_button['state'] = NORMAL
merge_button['state'] = NORMAL
I hope this helps future users!
As I understand you right you want something like:
...
ocr_button['state'] = DISABLED
ocr_button['background'] = '#*disabled background*'
ocr_button.bind('<Enter>', lambda e:ocr_button.configure(background='#...'))
ocr_button.bind('<Leave>', lambda e:ocr_button.configure(background='#...'))
merge_button['state'] = DISABLED
merge_button['background'] = '#*disabled background*'
merge_button.bind('<Enter>', lambda e:ocr_button.configure(background='#...'))
merge_button.bind('<Leave>', lambda e:ocr_button.configure(background='#...'))
...
...
ocr_button['state'] = ACTIVE
ocr_button['background'] = '#*active background*'
ocr_button.unbind('<Enter>')
ocr_button.unbind('<Leave>')
merge_button['state'] = ACTIVE
merge_button['background'] = '#*active background*'
merge_button.unbind('<Enter>')
merge_button.unbind('<Leave>')
...
If there are any errors, since I wrote it out of my mind or something isnt clear, let me know.
Update
the following code reproduces the behavior as you stated. The reason why this happens is how tkinter designed the standart behavior. You will have a better understanding of it if you consider style of ttk widgets. So I would recommand to dont use the automatically design by state rather write a few lines of code to configure your buttons how you like, add and delete the commands and change the background how you like. If you dont want to write this few lines you would be forced to use ttk.Button and map a behavior you do like
import tkinter as tk
root = tk.Tk()
def func_b1():
print('func of b1 is running')
def disable_b1():
b1.configure(bg='grey', command='')
def activate_b1():
b1.configure(bg='red', command=func_b1)
b1 = tk.Button(root,text='B1', bg='red',command=func_b1)
b2 = tk.Button(root,text='disable', command=disable_b1)
b3 = tk.Button(root,text='activate',command=activate_b1)
b1.pack()
b2.pack()
b3.pack()
root.mainloop()
I've wrote this simple app that I think could help all to reproduce the problem.
Notice that the state of the button when you click is Active.

I have used pyinstaller to generate exe from this tkinter gui example. But the generated exe in the dist folder does not show any gui. Is it because of the file reading operation? I have followed some examples. But the problem is still there.

im new to Python3.6.2
So I want a program that takes an input (Via text box from tkinter) and outputs a word in my custom "language"
with this function
def Mescre(n):
Words = (n)
Mes = str.maketrans('abcdefghijklmnopqrstuvwxyz', 'ektnopzcamjqwyuxsbfdiglhrv')
print(Words.translate(Mes))
and here's what i want the window to look like
from tkinter import*
root = Tk()
Mescre = Label(root, text="Input:")
English = Label(root , text="Output:")
label1.grid(row=0, sticky=E)
label2.grid(row=1, sticky=E)
entry1 = Entry(root)
entry2 = Entry(root)
entry1.grid = (row=0, column=1)
entry2.grid = (row=1, column=1)
root.mainloop()
if "hello" was in the Input text box, i want the output to be "coqqu" in the Output text box.
See my example below:
from tkinter import *
class App:
def __init__(self, root):
self.root = root
self.sv = StringVar()
self.Mes = str.maketrans('abcdefghijklmnopqrstuvwxyz', 'ektnopzcamjqwyuxsbfdiglhrv')
self.entry = Entry(self.root, textvariable = self.sv)
self.label = Label(self.root)
self.entry.pack()
self.label.pack()
self.sv.trace("w", self.callback)
def callback(self, *args):
self.label.configure({"text": self.entry.get().translate(self.Mes)})
root = Tk()
App(root)
root.mainloop()
Here we define a StringVar() to be the value of the attribute textvariable for the Entry widget.
We then assign a callback to a trace() on the variable so that whenever the variable is updated (When someone types in the Entry) we call callback().
Within callback() we use configure() on the Label widget in order to set the text to equal the post translation version of the value of the Entry widget.
This creates a "live updating" translation effect.
Here's a basic example:
import tkinter as tk
root = tk.Tk()
def Mescre():
val = textfield.get()
Words = (val)
Mes = str.maketrans('abcdefghijklmnopqrstuvwxyz', 'ektnopzcamjqwyuxsbfdiglhrv')
print(Words.translate(Mes))
textfield = tk.Entry(root)
textfield.pack()
button = tk.Button(root, command=Mescre, text='Push')
button.pack()
root.mainloop()
Updated:
import tkinter as tk
root = tk.Tk()
def Mescre():
val = textfield.get()
Words = (val)
Mes = str.maketrans('abcdefghijklmnopqrstuvwxyz', 'ektnopzcamjqwyuxsbfdiglhrv')
translation = Words.translate(Mes)
#print(translation)
outputfield.delete(0, tk.END)
outputfield.insert(0, translation)
textfield = tk.Entry(root)
textfield.pack()
outputfield = tk.Entry(root)
outputfield.pack()
button = tk.Button(root, command=Mescre, text='Push')
button.pack()
root.mainloop()
The code picture needs to fit the screen size perfectly. I saw a bunch of tutorials but nothing seems to work.I tried adding a canvas but it covers half the screen.All my buttons go under the image itself not over it. It's getting on my nerves .
here's my code :

When I run it the labels are created but not the entries.
You have forgetten to grid the entries.
