Background: with the last update my Arch Linux installation changed its
standard monospace font to Inconsolata. I like this font, it works well
in all my applications with one exception: in tkinter scripts all text
using monospace is rendered like this:
t h i s l o o k s b a d .
This seems to be a rather complicated sort of bug, not located in Tcl/Tk
or tkinter itself, as far as I could find out. So for the time being I'd
like to change the font in tkinter scripts - but not by styling every
single widget class I use. I tried two things: styling ttk.Widget and
reconfiguring TkFixedfont.
In case it's important: Python version is 3.8.3.
Results: defining a style for ttk.Widget doesn't change anything:
import tkinter as tk
from tkinter import ttk
from tkinter import font
def main():
root = tk.Tk()
veramono = font.Font(family="Bitstream Vera Sans Mono", size=9)
# Doesn't change anything:
#ttk.Style().configure("TWidget", font=veramono)
# Doesn't change anything either:
verastyle = ttk.Style()
verastyle.configure("TWidget", font=veramono)
root.title("Titelschrift?")
ttk.Label(root, text="Wie sieht das aus?").pack(
side="top", padx=5, pady=5)
versuchstext = tk.StringVar()
versuchstext.set("Und das hier?")
ttk.Entry(root, textvariable=versuchstext).pack(
side="top", padx=5, pady=5)
root.mainloop()
if __name__ == "__main__":
main()
Initializing Label and Entry with "style=verastyle" results in this
exception:
Traceback (most recent call last):
File "./changefont.pyw", line 26, in <module>
main()
File "./changefont.pyw", line 17, in main
ttk.Label(root, text="Wie sieht das aus?",
File "/usr/lib/python3.8/tkinter/ttk.py", line 759, in __init__
Widget.__init__(self, master, "ttk::label", kw)
File "/usr/lib/python3.8/tkinter/ttk.py", line 557, in __init__
tkinter.Widget.__init__(self, master, widgetname, kw=kw)
File "/usr/lib/python3.8/tkinter/__init__.py", line 2567, in __init__
self.tk.call(
_tkinter.TclError: Layout <tkinter.ttk.Style object at 0x7f3fc412a6a0>
not found
And trying to reconfigure TkFixedFont like this:
def main():
root = tk.Tk()
fix = font.nametofont("TkFixedFont")
fix.configure(family="Bitstream Vera Sans Mono")
root.title("Titelschrift?")
ttk.Label(root, text="Wie sieht das aus?", font=fix).pack(
side="top", padx=5, pady=5)
versuchstext = tk.StringVar()
versuchstext.set("Und das hier?")
ttk.Entry(root, textvariable=versuchstext).pack(
side="top", padx=5, pady=5)
root.mainloop()
doesn't change anything.
What's the right way to do this? Changing the standard monospace font
for all of the installation would be possible, of course, but, as I
said, it's quite nice for everything else.
Thank you for help,
Sibylle
