ttk.Style is used to style objects from ttk, which Text is not. To set the font on a tkinter.Text widget you need to use tkinter.font.Font.
import tkinter.font

BTW a scrolled Text widget is built into tkinter in the ScrolledText widget.

help please
You could try adding highlightthickness=0:
canvas = Canvas(win2, width=1000, height=700, highlightthickness=0)
Try this,
Source: Check
import tkinter # assuming Python 3 for simplicity's sake
import tkinter.ttk as ttk
root = tkinter.Tk()
f = tkinter.Frame(relief='flat')
lF = ttk.LabelFrame(root, labelwidget=f, borderwidth=4)
lF.grid()
b = ttk.Button(lF, text='')
b.grid()
root.mainloop()
Or try this
Canvas=Canvas(self,width=width/2,height=height/2,bg=bgCanvasColor,borderwidth=0, highlightthickness=0)

P.S. Do change your initialdir. I changed it as I am not on Windows.
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 .

How can i modify text (Add or delete) file which i opened with Tkinter?
For example when i open some file with notebad i can easily modify text.
I cant figure out how can i do it in tkinter.
There is my code:

from tkinter import filedialog
import re
class Window(Frame):
def __init__(self, master=None):
Frame.__init__(self, master)
self.master = master
self.master.title("JoNotepad")
self.pack(fill=BOTH, expand=1)
menu = Menu(top)
top.config(menu=menu)
self.file_menu = Menu(menu)
menu.add_cascade(label="File", menu=self.file_menu)
self.file_menu.add_command(label="New")
self.file_menu.add_command(label="Open", command=self.open_file_function)
self.file_menu.add_command(label="Save")
self.file_menu.add_separator()
self.file_menu.add_command(label="Exit")
self.listNodes = Listbox(top, height=200, width=200)
self.listNodes.pack(side=LEFT, fill=Y, expand=True)
self.scrollbar = Scrollbar(top, orient="vertical")
self.scrollbar.config(command=self.listNodes.yview)
self.scrollbar.pack(side=RIGHT, fill=Y, expand=True)
self.listNodes.config(yscrollcommand=self.scrollbar.set)
def open_file_function(self):
self.file_save = filedialog.askopenfilename(initialdir = "/", title = "Select file", filetypes = (("txt files", "*.txt"), ("All files", "*.*")))
with open(self.file_save) as file:
for i in file:
self.listNodes.insert(END, i)
top = Tk()
top.geometry("1000x1000")
ap = Window(top)
top.mainloop()
You should use the tkinter Text widget instead of the Listbox. The Text widget allows you to perform want you want to do (including add text, delete text, select text, etc).
Here is your code, using the Text widget.
from tkinter import *
from tkinter import filedialog
import re
class Window(Frame):
def __init__(self, master=None):
Frame.__init__(self, master)
self.master = master
self.master.title("JoNotepad")
self.pack(fill=BOTH, expand=1)
menu = Menu(top)
top.config(menu=menu)
self.file_menu = Menu(menu)
menu.add_cascade(label="File", menu=self.file_menu)
self.file_menu.add_command(label="New")
self.file_menu.add_command(label="Open", command=self.open_file_function)
self.file_menu.add_command(label="Save")
self.file_menu.add_separator()
self.file_menu.add_command(label="Exit")
self.text = Text(top, height=200, width=200) #Use Text widget insted of Listbox
self.text.pack(side=LEFT, fill=Y, expand=True)
self.scrollbar = Scrollbar(top, orient="vertical")
self.scrollbar.config(command=self.text.yview)
self.scrollbar.pack(side=RIGHT, fill=Y, expand=True)
# change all occurances of self.listNodes to self.text
self.text.config(yscrollcommand=self.scrollbar.set)
def open_file_function(self):
self.file_save = filedialog.askopenfilename(initialdir = "/", title = "Select file", filetypes = (("txt files", "*.txt"), ("All files", "*.*")))
with open(self.file_save) as file:
for i in file:
self.text.insert(END, i)
top = Tk()
top.geometry("1000x1000")
ap = Window(top)
top.mainloop()

Thank you!
You can either do the designing part in your code or through a QT Designer which ships with PyQt4. and some examples can be found in the path C:\Python26\Lib\site-packages\PyQt4\examples and documentation in the path C:\Python26\Lib\site-packages\PyQt4\doc\html\modules.html if you are using windows. Hope this helps.
