Load external font and does not show font in the window

[buran]

If I may suggest something. Instead of using 1 and 2, use bool variable (and meaningful name :))

import pyglet
import time

use_colon = True
 
pyglet.font.add_file('digital-7.ttf')
window = pyglet.window.Window()
window.set_fullscreen(True)
label = pyglet.text.Label('',
                    font_name='Digital-7',
                    font_size=400,
                    x=window.width//2, y=window.height//2,
                    anchor_x='center', anchor_y='center')

def update_clock(dt):
    global use_colon
    label.text = time.strftime("%H:%M %P" if use_colon else "%H.%M %P")
    use_colon = not use_colon

pyglet.clock.schedule_interval(update_clock, 1)
 
@window.event
def on_draw():
    window.clear()
    label.draw()
 
pyglet.app.run()

however using global variables is bad, so a better solution is to define a class and work with it

import pyglet
import time

class DigitalClock:
    def __init__(self, window):
        self.use_colon = True
        self.label = pyglet.text.Label('',
                    font_name='Digital-7',
                    font_size=400,
                    x=window.width//2, y=window.height//2,
                    anchor_x='center', anchor_y='center')

    def update(self):
        self.label.text = time.strftime("%H:%M %P" if self.use_colon else "%H.%M %P")
        self.use_colon = not self.use_colon

def update_clock(dt, digital_clock):
    digital_clock.update()

 
pyglet.font.add_file('digital-7.ttf')
window = pyglet.window.Window()
window.set_fullscreen(True)


digital_clock = DigitalClock(window)
pyglet.clock.schedule_interval(update_clock, 1, digital_clock=digital_clock)
 
@window.event
def on_draw():
    window.clear()
    digital_clock.label.draw()
 
pyglet.app.run()

This is very basic example. the class can be customized at instantiation (font, size, etc.)

As to tkinter&pyglet code not working on Linux, but working on Windows - I suspect it's just one of those OS dependent quirks, not problem with your code per se...
If you insist on using tkinter, why not install the font, instead of trying to load it from file without installation? In this case no pyglet will be needed at all

Wow and thanks again... Those last code a bit hard to understand how it works but I need more learning...
However, I did install the font and code with Tkinter can't see it. here what I did:
> cp Digital-7.ttf /home/pi/.local/fonts
> fc-cache -f -v

did I miss something?

Also, I use font list codes from the internet it show me list a lot but no Digital-7. here the code that I copied from the internet:

from tkinter import *
from tkinter import font

root = Tk()
root.title('Font Families')
fonts=list(font.families())
fonts.sort()

def populate(frame):
    '''Put in the fonts'''
    listnumber = 1
    for item in fonts:
        label = "listlabel" + str(listnumber)
        label = Label(frame,text=item,font=(item, 16)).pack()
        listnumber += 1

def onFrameConfigure(canvas):
    '''Reset the scroll region to encompass the inner frame'''
    canvas.configure(scrollregion=canvas.bbox("all"))

canvas = Canvas(root, borderwidth=0, background="#ffffff")
frame = Frame(canvas, background="#ffffff")
vsb = Scrollbar(root, orient="vertical", command=canvas.yview)
canvas.configure(yscrollcommand=vsb.set)

vsb.pack(side="right", fill="y")
canvas.pack(side="left", fill="both", expand=True)
canvas.create_window((4,4), window=frame, anchor="nw")

frame.bind("<Configure>", lambda event, canvas=canvas: onFrameConfigure(canvas))

populate(frame)

root.mainloop()

Font list snapshot:

/home/pi/.local/fonts

not sure, but shouldn't it be in /home/pi/.local/share/fonts

Also I see you do fc-cache, but it doesn't hurt to reboot :-)

[ATARI_LIVE]

I put wrong path for the fonts. correct is /usr/share/fonts/truetype and do fc-cache and WORKED with my original code!
now it all resolved.

THANK YOU FOR HELPS it's lot!

[buran]

WORKED with my original code!

if the font is installed, no need of pyglet, so you can change your original code

Yup!

I was looking for a solution to a similar font problem, but I didn't understand anything from what you wrote. Could you explain in human language how I can fix this problem with fonts? I sort of load my own salt life font, but it doesn't show up in the window. Am I making some kind of primitive mistake? I'm just here to find a solution, but as it turns out, I'm not very good at all these codes. If someone helped me, I would be very grateful. Thank you in advance.
