Is there any way to resize button size in python tkinter?
I have tried to resize button size in python 3.7.2 tkinter by using button.config(width = 100, hight = 100), but it didn't work properly. Is there any way to resize button?
I use Python 3.7.2 and Windows 10.
import tkinter as tk
win = tk.Tk()
#*** Settings ***#
win.title("Project_title")
win.geometry("660x450")
win.resizable(False, False)
wall = tk.PhotoImage(file = "pictures_gui.gif")
wall_label = tk.Label(image = wall)
#*** Settings ***#
#*** Test code ***#
def click_me():
button.configure(text="** I have been clicked")
button = tk.Button(win,text = "Click me!",command=click_me)
button.grid(column=1, row=0)
button.config(width = 100,hight = 100)
#*** Test code ***#
win.mainloop()
I'm guessing you want to set the button size in pixels. The button size defaults to characters when the button displays text but no image. To get the size to be pixels you have to display an image in the button. See the example below:
import tkinter as tk
win = tk.Tk()
win.geometry("660x450")
win.resizable(False, False)
def click_me():
button.configure(text="** I have been clicked")
# Create a transparent image to allow Button size in pixels
pixel = tk.PhotoImage(file='images/pixel.png')
button = tk.Button(win, text="Click me!", command=click_me,
image=pixel, compound='center')
button.grid(column=1, row=0)
button.config(width=100, height=100) # Config size in pixels
win.mainloop()
The pixel.png image is 1x1 pixel and has transparent color.

I am trying to create a translucent window in Tkinter like the one in windows 11
How to do this? If we cannot do this can we capture a part of a screen and blur it using cv2 and use it as a continuously updating background?
No, this is not directly possible with tkinter. But:
If you use PIL, you can get the location of the window, and then take a screenshot, then blur it and then make it your app background. But this wont work if user tries to move/resize the application. But here is a rough code:
from tkinter import *
from PIL import ImageTk, ImageGrab, ImageFilter # pip install Pillow
root = Tk()
root.overrideredirect(1) # Hide the titlebar etc..
bg = Canvas(root)
bg.pack(fill='both',expand=1)
root.update()
# Get required size and then add pixels to remove title bar and window shadow
left = root.winfo_rootx()
top = root.winfo_rooty()
right = left + root.winfo_width()
bottom = top + root.winfo_height()
root.withdraw() # Hide the window
img = ImageGrab.grab((left,top,right,bottom)) # Get the bg image
root.deiconify() # Show the window
img = img.filter(ImageFilter.GaussianBlur(radius=5)) # Blur it
img = ImageTk.PhotoImage(img)
bg.create_image(0,0, image=img, anchor='nw') # Show in canvas
label = Label(root,text='This is a translucent looking app')
bg.create_window(bg.winfo_width()/2,bg.winfo_height()/2,window=label) # Position in the center
root.mainloop()
Output with tkinter:
tkinter is not the best choice if you are trying to go for a modern look, use PyQt and check qtacrylic
Output with PyQt:
For live blur (native Windows blur) use "BlurWindow":
python -m pip install BlurWindow
from tkinter import *
from ctypes import windll
from BlurWindow.blurWindow import blur
root = Tk()
root.config(bg='green')
root.wm_attributes("-transparent", 'green')
root.geometry('500x400')
root.update()
hWnd = windll.user32.GetForegroundWindow()
blur(hWnd)
def color(hex):
hWnd = windll.user32.GetForegroundWindow()
blur(hWnd,hexColor=hex)
e = Entry(width=9)
e.insert(0,'#12121240')
e.pack()
b = Button(text='Apply',command=lambda:[color(e.get())])
b.pack()
root.mainloop()
I am using Tkinter, I want to clear the canvas using a button(close_button) but the camera is always on and the button not doing anything I want the button to close the camera feed and reset the canvas so that the canvas becomes as it was before I opened the cam
from tkinter import*
import tkinter as tk
from PIL import Image, ImageTk
import cv2
# new window function which will be called when button pressed
class OpenCam():
def __init__(self, window, cap):
self.window = window
self.cap = cap
self.width = self.cap.get(cv2.CAP_PROP_FRAME_WIDTH)
self.height = self.cap.get(cv2.CAP_PROP_FRAME_HEIGHT)
self.interval = 20 # Interval in ms to get the latest frame
# Create canvas for image
self.canvas = tk.Canvas(self.window, width=self.width, height=self.height)
self.canvas.place(x=100,y=100)
# close Button need to close cam and reset canvas
close_button = tk.Button(root, text="close", bg='black', fg='white', command=self.canvas.delete() )
close_button.place(x=610,y=0)
# Update image on canvas
self.update_image()
def update_image(self):
# Get the latest frame and convert image format
self.image = cv2.cvtColor(self.cap.read()[1], cv2.COLOR_BGR2RGB) # to RGB
self.image = Image.fromarray(self.image) # to PIL format
self.image = ImageTk.PhotoImage(self.image) # to ImageTk format
# Update image
self.canvas.create_image(0, 0, anchor=tk.NW, image=self.image)
# Repeat every 'interval' ms
self.window.after(self.interval, self.update_image)
def new_window():
OpenCam(root, cv2.VideoCapture(0))
#create original window
root = tk.Tk()
root.title("ADD CAM: ")
canvas = tk.Canvas(root, height=1000, width=1000)
canvas.pack()
#create button that will be placed
button = tk.Button(root, text="ADD CAM", bg='black', fg='white', command=new_window )
button.place(x=0,y=0)
root.mainloop()
EDIT: I found the solution! My xorg settings were all wacky because I have an ultrawide monitor, and it had no idea what size (and therefore dpi) my monitor was. Explicitly setting the display and font dpi in X's settings fixed the rendering in all GUI's.
ORIGINAL:
When I run any tkinter program, many of the widgets render at around 1/2 size, especially text. Why is this happening? My window manager is Window Maker, and I'm running the latest version of Tcl/Tk.
Any help will be greatly appreciated!
My code:
import tkinter as tk
window = tk.Tk()
label = tk.Label(text="Name")
entry = tk.Entry()
button = tk.Button(text="Submit")
label.pack()
entry.pack()
button.pack()
window.mainloop()
Window manager: Window Maker 0.95.0
Tk: tk 8.6.10-2
Screenshot:
In tkinter you can only change the size of a label with the font atribute, and same goes for the text inside the button. The button size can be changed with the width and height atribute.
from tkinter import *
window = Tk()
label = Label(text="Name", font='Helvetica 15')
entry = Entry()
button = Button(text="Submit",font ='Helvetica 15', height="3", width="10")
label.pack(pady = 5) # add pady inside the pack
entry.pack()
button.pack(pady = 5)
window.mainloop()
I'm learning Tkinter at the moment. From my book, I get the following code for producing a simple vertical scrollbar:
from tkinter import * # Import tkinter
class ScrollText:
def __init__(self):
window = Tk() # Create a window
window.title("Scroll Text Demo") # Set title
frame1 = Frame(window)
frame1.pack()
scrollbar = Scrollbar(frame1)
scrollbar.pack(side = RIGHT, fill = Y)
text = Text(frame1, width = 40, height = 10, wrap = WORD,
yscrollcommand = scrollbar.set)
text.pack()
scrollbar.config(command = text.yview)
window.mainloop() # Create an event loop
ScrollText() # Create GUI
which produces the following nice output:
enter image description here
However, when I then try to change this code in the obvious way to get a horizontal scrollbar, it's producing a weird output. Here's the code I'm using
from tkinter import * # Import tkinter
class ScrollText:
def __init__(self):
window = Tk() # Create a window
window.title("Scroll Text Demo") # Set title
frame1 = Frame(window)
frame1.pack()
scrollbar = Scrollbar(frame1)
scrollbar.pack(side = BOTTOM, fill = X)
text = Text(frame1, width = 40, height = 10, wrap = WORD,
xscrollcommand = scrollbar.set)
text.pack()
scrollbar.config(command = text.xview)
window.mainloop() # Create an event loop
ScrollText() # Create GUI
and here's what I get when I run this:
enter image description here
You're assigning horizontal scrolling, xscrollcommand, to a vertical scrollbar. You need to modify Scrollbar's orient option to 'horizontal' which is by default 'vertical'.
Try replacing:
scrollbar = Scrollbar(frame1)
with:
scrollbar = Scrollbar(frame1, orient='horizontal')

Is there a way to remove the white background behind the username label? I know how to change the colour of it, but how do I remove it all together.

sorry for posting twice, apparently there wasn't enough text and too much code.
It sounds like you are asking how to make your Label have a transparent background. From my understanding at the moment tkinter does not have this feature for widgets like labels and buttons. However it is still possible to create your own see-through label with Canvas
Here is an example of using Canvas to achieve something similar to what you are looking to do.
import tkinter as tk
root = tk.Tk()
mycanvas = tk.Canvas(root, width = 200, height = 25)
mycanvas.create_rectangle(0, 0, 100, 40, fill = "green")
mycanvas.pack(side = "top", fill = "both", expand = True)
text_canvas = mycanvas.create_text(10, 10, anchor = "nw")
mycanvas.itemconfig(text_canvas, text="Look no background! Thats new!")
root.mainloop()
