I am using tkinter to create a GUI. I use PIL to import an image as the background. Here is my code:
root = tk.Tk()
root.title("DFUInfo-v1")
img = ImageTk.PhotoImage(Image.open("background.jpg"))
l=Label(image=img)
l.pack()
root.configure(bg='white')
root.geometry("490x280")
In my app, buttons are rounded. But when I use the image, the background does not match the round buttons, here is the image:
Can somebody help me pls? Thanks
Here is how you can create rounded "buttons" in tkinter (what determines the visible shape is how the image looks):
from tkinter import Tk, Canvas
from PIL import Image, ImageTk
# use your images here
# open your images (my preference is to use `.open` before initialising `Tk`)
img = Image.open('rounded.png')
# resize to match window geometry
bg = Image.open('space.jpg').resize((500, 400))
# the function to call when button clicked
def func(event=None):
print('clicked')
root = Tk()
root.geometry('500x400')
# here are the converted images
photo = ImageTk.PhotoImage(img)
bg = ImageTk.PhotoImage(bg)
# from now on this will be the "root" window
canvas = Canvas(root, highlightthickness=0)
canvas.pack(fill='both', expand=True)
# add background
canvas.create_image(0, 0, image=bg, anchor='nw')
# create button and you have to use coordinates (probably can make
# custom grid system or sth)
btn = canvas.create_image(250, 200, image=photo, anchor='c')
# bind the "button" to clicking with left mouse button, similarly
# as `command` argument to `Button`
canvas.tag_bind(btn, '<Button-1>', func)
root.mainloop()
Most of the explanation is in the code comments, but note that the bound sequence works for the whole image but images are always square so you can click the button being outside of the visible part but only as far as the image goes, it is most certainly possible to create a button that doesn't have such issues but that requires some math
Important (suggestion):
I strongly advise against using wildcard (*) when importing something, You should either import what You need, e.g. from module import Class1, func_1, var_2 and so on or import the whole module: import module then You can also use an alias: import module as md or sth like that, the point is that don't import everything unless You actually know what You are doing; name clashes are the issue.

I am trying to display an image on my desktop without any boarder or window, like an image floating in the desktop. I also want to be able to control its position once it has been created, with the arrow keys or with a line of code that changes its position with some coordinate system of some sorts. I haven't found any method after some reaserch (not in Python, at least).
If that's not possible, please recommend another programming language that can.
You can use Tkinter for this.
I made a little example:
Python3
from tkinter import Toplevel, Tk, Label, PhotoImage
win = Tk()
win.attributes('-alpha', 0.0)
win.iconify()
window = Toplevel(win)
window.geometry("500x500+100+100")
window.overrideredirect(1)
photo = PhotoImage(file="test.png")
label = Label(window, image=photo)
label.pack()
win.mainloop()
Python2
from Tkinter import Toplevel, Tk, Label
import ImageTk
win = Tk()
win.attributes('-alpha', 0.0)
win.iconify()
window = Toplevel(win)
window.geometry("500x500+100+100") # create an window 500x500 pixel, 100 pixels from the upper left corner
window.overrideredirect(1) # Take the border away
photo = ImageTk.PhotoImage(file="test.png")
label = Label(window, image=photo)
label.pack()
win.mainloop()
I'm an entry level python coder looking to create a Guess Who styled game. At university, I've yet to learn how to import images and bind them to fixed places on a screen (resembling the game board). Is there any way to click on a specific image and have an onClickEvent to occur, where that specific character(image) is chosen.
The majority of my coding abilities are in python, but I am skeptical if this is the best possible language to do a project like this in.
Every GUI has Button widget which is clickable and (mostly) can display image.
But mostly in GUI you can assign click event to every object ie. Label with Image.
ie. Tkinter
import tkinter as tk
from PIL import Image, ImageTk
# --- functions ---
def on_click(event=None):
# `command=` calls function without argument
# `bind` calls function with one argument
print("image clicked")
# --- main ---
# init
root = tk.Tk()
# load image
image = Image.open("image.png")
photo = ImageTk.PhotoImage(image)
# label with image
l = tk.Label(root, image=photo)
l.pack()
# bind click event to image
l.bind('<Button-1>', on_click)
# button with image binded to the same function
b = tk.Button(root, image=photo, command=on_click)
b.pack()
# button with text closing window
b = tk.Button(root, text="Close", command=root.destroy)
b.pack()
# "start the engine"
root.mainloop()
Graphic modules like PyGame can display image too, and have click event but sometimes you have to check manually if you clicked in area with image (and you have to create mainloop manually)
I'd say TkInter is your best bet. A little bit cumbersome at first but it's good for beginners. You should be able to make a nice Graphical User Interface with it which will open a window that holds your pictures, menus, buttons, etc...
Take a look at useful docs and examples here.
If Python is not a requirement, I too would also recommend JS, HTML and CSS (you'll have to use all three together. Sounds scarier than it is :P)
I am making a small pop up to a text game I am making. I just want a small frame to pop up with some text and a picture to the far left but in a custom size and position. How would I do this? How do I insert text and change the image position and size, this is my current code, it works as in there are no errors and the image shows.
from tkinter import *
import time, sys
root = Tk()
root.configure(background='#16e116')
root.title('Pop Up')
root.geometry('300x200')
photo = PhotoImage(file='file.gif')
w = Label(root, image=photo)
w.pack()
root.mainloop()
If you want your image to be a different size (without it being deformed by resizing the widget) you have to make it the desired size in your image editor.
If you want to change the image position then use grid() where pack() has very limited placement options.
If you want text on a label, then use: text = Label(root, text="Hello world!"). This also comes with various options and styles such as font and it's size.
If you want the text over the image then use grid() and place it in the middle of the image by using rows and columns.
import tkinter
from tkinter import *
root = tkinter.Tk()
root.configure(background='#16e116')
root.title('Pop Up')
root.geometry('300x200')
photo = PhotoImage(file='file.gif')
w = Label(root, image=photo)
text = Label(root, text="Hello world!")
w.grid(row=3, column=3)
text.grid(row=3, column=3)
root.mainloop()
Although, the label will still have the background around it but you change the background colour using widgetname.config(bg="Colour")to make it suit your standards.
Now of course, I can't be sure the above will work because I don't have file.gif but you should also read tutorials before jumping straight into code to avoid confusion.
I am creating an Arduino interface on Sublime using python Tkinter..
I need to show a text over an image. Located in the middle of the screen (512, 200). I don't know how to do it using this library
import Tkinter as tk
from Tkinter import *
root = tk.Tk()
root.geometry("1024x574")
root.title("window")
photo = tk.PhotoImage(file= r"hi.gif")
cv = tk.Canvas()
cv.pack(side='top', fill='both', expand='yes')
cv.create_image(0, 0, image=photo, anchor='nw')
text=['my text']
root.mainloop()
Any suggestions?
You need to create a tk label widget and add your text to it. Then you need to use the tk label option compound=.
Taken directly from http://effbot.org/tkinterbook/label.htm:
"compound=
Controls how to combine text and image in the label. By default, if an image or bitmap is given, it is drawn instead of the text. If this option is set to CENTER, the text is drawn on top of the image. If this option is set to one of BOTTOM, LEFT, RIGHT, or TOP, the image is drawn besides the text (use BOTTOM to draw the image under the text, etc.). Default is NONE."
The following is a minimal but working example that accomplishes what you asked for:
import tkinter as tk
from PIL import Image, ImageTk
root = tk.Tk()
image = Image.open('hi.gif')
tk_image = ImageTk.PhotoImage(image)
label = tk.Label(root, text='Some Plain Text', image=tk_image, compound='center')
label.pack()
root.mainloop()
I'm trying to make a script which will enable me to dynamically update an image object and then post the updated image to a Tkinter Canvas widget. The code here is prototype code, just to get the basics down. The aim here is to put a blue pixel on the image being displayed by the canvas, at the click location.
Something very strange is going on here. I'm using the Wing IDE, and if I run this code through the debugger, with a breakpoint at any line in the woohoo function, and then continue execution after hitting the breakpoint, the code works exactly as expected- putting a blue pixel on the image. If I run the code normally, or through the debugger with no breakpoints, the image is never updated. This leads me to the conclusion that there is some internal wizardry going on which I haven't got much hope of understanding without aid.
I'd really like to know the best way to go about this (or any way, I guess), and if someone could explain to me what's going on under the hood that'd be really cool. Thanks.
from Tkinter import *
from PIL import Image, ImageTk
def woohoo(event):
original.putpixel((event.x,event.y),(0,0,255))
newpic = ImageTk.PhotoImage(original)
c.create_image((0,0),image=newpic, anchor="nw")
main = Tk()
c = Canvas(main, width=300, height=300)
main.geometry("300x300+0+0")
c.pack()
original = Image.open("asc.bmp")
picture = ImageTk.PhotoImage(original)
c.create_image((0,0),image=picture, anchor="nw")
c.bind("<Button-1>", woohoo)
main.mainloop()
My guess is, you're creating a new image in a function. The reference to the image is a local variable. When the function exits, the reference is garbage collected which causes the new image to be destroyed. Most likely, running interactively causes the garbage collector to run differently (perhaps more lazily?)
Changed a little of the other post to work with Python 3+ :
from tkinter import *
def stuff(event):
global picture3
picture3 = PhotoImage(file='picture2.png')
c.itemconfigure(picture2, image = picture3)
main = Tk()
c = Canvas(main, width=300, height=300)
c.pack()
picture = PhotoImage(file='picture1.png')
picture2 = c.create_image(150,150,image=picture)
c.bind("<Button-1>", stuff)
main.mainloop()
try it like this:
from Tkinter import *
from PIL import Image, ImageTk
def woohoo(event):
global picture #
original.putpixel((event.x,event.y),(0,0,255))
picture = ImageTk.PhotoImage(original)#
c.itemconfigure(myimg, image=picture)#
main = Tk()
c = Canvas(main, width=300, height=300)
main.geometry("300x300+0+0")
c.pack()
original = Image.open("asc.bmp")
picture = ImageTk.PhotoImage(original)
myimg = c.create_image((0,0),image=picture, anchor="nw")#
c.bind("<Button-1>", woohoo)
main.mainloop()
