I am trying to make an animation using Tkinter Text Widget. I want it to write each frame on the Text widget every 1 second. Here is my current code:
from tkinter import *
frames = ["-o","--o","---o"]
speed = 1000
def clear():
text.delete(0.0, END)
def movie(event):
text.delete(0.0, END)
for frame in range(len(frames)):
text.insert(END, frames[frame])
root.after(speed, clear)
root = Tk()
root.title("Animation")
root.minsize(400,400)
root.maxsize(width=root.winfo_screenwidth()-20, height=root.winfo_screenheight()-20)
text = Text(root, highlightcolor="black", highlightbackground="white",width=400, insertbackground="white", height=400, foreground="white", background="black", font="Courier")
text.pack()
root.bind("<Return>", movie)
But, the output of this code is
-o--o---o
instead of:
-o[wait a second][clear]--o[wait a second][clear]---o[wait a second][clear]
How can I fix this?
I found my problem! The .after() function almost works like the return function. In that, when called the current function is stopped. This is my fixed code:
from tkinter import *
frame = 0
frames = ["-o","--o","---o"]
speed = 1000
def clear():
text.delete(0.0, END)
def movie(event=""):
global frame
if frame < len(frames):
text.delete(0.0, END)
text.insert(END,frames[frame])
frame += 1
root.after(speed, movie)
def movie1(event):
global frame
frame = 0
movie("<Return>")
root = Tk()
root.title("Animation")
root.minsize(400,400)
root.maxsize(width=root.winfo_screenwidth()-20, height=root.winfo_screenheight()-20)
text = Text(root, highlightcolor="black", highlightbackground="white",width=400, insertbackground="white", height=400, foreground="white", background="black", font="Courier")
text.pack()
root.bind("<Return>", movie)

So I'm using the tkinter and pymupdf libraries to add blank pages to a desired location. This is done by pressing a button which inserts the blank page below the page on the button. My issue is that once it inserts the blank page, the original page order now changes.
When you press a button corresponding to a page number, it inserts the blank page, but if you try with a second blank page, it inserts it at the wrong place because it messes up the button's assigned page number. Please help I'm losing my hair.

The code below is simple i am just creating two frames and trying to display progressbar with image in first then after 6 seconds switching two frame 2 but the first frame is completely white for some reason. Hope someone can help :)
from PIL import ImageTk,Image
from tkinter import ttk
import time
frames=['frame1','frame2']
#canvas
root=Tk()
root.title('Anigame Tools V1.0')
root.iconbitmap('anigametoolsicon.ico')
#Frame Functions
frame1= Frame(root)
frame2= Frame(root)
frame1.pack()
frames=[frame1,frame2]
# progress bar
p = ttk.Progressbar(frame1, orient=HORIZONTAL, length=200, mode="determinate", takefocus=True, maximum=100)
p['value'] = 0
p.grid(row=1, column=0)
def start():
if p['value'] != 80:
p['value'] += 20
root.after(1000, start)
frame1.after(1000, start)
def show_frame(framename):
for i in frames:
i.pack_forget()
framename.pack()
# intro
intimg=Image.open("anigametoolsicon.png")
introimg = ImageTk.PhotoImage(intimg)
intro = Label(frame1,image=introimg)
intro.grid(row=0, column=0)
# frame2
anigametoolsad = Label(frame2, text='Anigame Tools Ver1.0')
anigametoolsad.grid(column=0, row=0, columnspan=3)
root.after(6000, show_frame(frame2))

Just a simple example of a problem I experienced:
from tkinter import *
root = Tk()
frame = Frame(root)
label = Label(frame, text = "Hey")
label.pack()
def packframe():
frame.pack()
def destroyframe():
frame.destroy()
pack_button = Button(root, text = "pack", command = packframe)
pack_button.pack()
des_button = Button(root, text = "destroy", command = destroyframe)
des_button.pack()
Once I press the destroy button, I cannot pack it back again on the screen with the pack_button. Im not sure why is it so, but I would appreciate both explanaition and a solution
I would like a text box to ask for input in a tkinter window, then use that input as a parameter to call a function that draws a Sierpinski triangle. My buttons work but my input box does not. I keep trying to fix my code but it is not working, any help would be appreciated.
import tkinter as tk
from tkinter import *
root = tk.Tk()
frame = tk.Frame(root)
frame.pack()
root.title('Fractals') #titles the button box
top_frame = tk.Frame()
mid_frame = tk.Frame()
prompt_label = tk.Label(top_frame, \
text='Enter a number of iterations (more is better):')
iterations = tk.Entry(root,bd=1)
itr=iterations.get()
itr=int(itr)
button = tk.Button(frame,
text="QUIT",
fg="red",
command=quit)
button.pack(side=tk.LEFT)
sTriangle = tk.Button(frame,
text="Triangle",
command=lambda: sierpinski(fred, (-500,-500), (500,-500),
(0,500),itr))
sTriangle.pack(side=tk.LEFT)
fsquare = tk.Button(frame,
text="Square",
command=fractalsquare(fred,(-500,-500),(500,-500),
(500,500),(-500,500),itr))
fsquare.pack(side=tk.LEFT)
root.mainloop()
There are several issues:
1) Choose one way to import tkinter or confusion will result
2) You should provide a master for your Frames and then pack them. Pay attention on where the frames appear and what they contain.
3) It's usual to assign a textvariable to the Entry which will contain what you enter into it. The textvariable should be a tk.StringVar.
4) If a Button has a callback function, it must be defined before you create the button.
5) The variable fred is not defined.
Example of how you can write it:
import tkinter as tk
root = tk.Tk()
root.title('Fractals') #titles the button box
# Create the Label at the top
top_frame = tk.Frame(root) # Top Frame for
top_frame.pack()
prompt_label = tk.Label(top_frame,
text='Enter a number of iterations (more is better):')
prompt_label.pack()
# Create the Entry in the middle
mid_frame = tk.Frame(root)
mid_frame.pack()
itr_string = tk.StringVar()
iterations = tk.Entry(mid_frame,textvariable=itr_string)
iterations.pack()
fred=None # Was not defined...
# Create Buttons at the bottom
bot_frame = tk.Frame(root)
bot_frame.pack()
button = tk.Button(bot_frame, text="QUIT", fg="red", command=quit)
button.pack(side=tk.LEFT)
def sierpinski(*args): # sTriangle button callback function
itr = int(itr_string.get()) # How to get text from Entry
# if Entry does not contain an integer this will throw an exception
sTriangle = tk.Button(bot_frame, text="Triangle",
command=lambda: sierpinski(fred, (-500,-500), (500,-500),(0,500),itr_string))
sTriangle.pack(side=tk.LEFT)
def fractalsquare(*args): pass # fsquare button callback function
fsquare = tk.Button(bot_frame, text="Square", command=fractalsquare(fred,
(-500,-500),(500,-500),(500,500),(-500,500),itr_string))
fsquare.pack(side=tk.LEFT)
root.mainloop()
