I am attempting to create a very simple image viewer in tkinter with two simple buttons view and close. I have the close button functioning as intended but I am unable to get my view button to open the specified image in my file directory. I have tried importing ImageTK to write a button command to open it but have so far been unsuccessful.
import tkinter as tk
from PIL import ImageTk,Image
class image_viewer:
def __init__(self, win):
self.root = win
self.root.title('ImageViewer')
self.root.geometry('400x350')
self.btnView = tk.Button(text='View', command= ImageTk.PhotoImage(Image.open(r"C:\Users\SteveSmith\eclipse-workspace\SteveSmith-ex1\src\raw\pythonIsFun.jpg")))
self.btnView.pack(side=tk.LEFT)
self.btnView.place(x=20, y=265)
self.btnClose = tk.Button(text='close', command=self.root.destroy)
self.btnClose.pack(side=tk.LEFT)
self.btnClose.place(x=65, y=265)
def main():
root = tk.Tk()
image_viewer(root)
root.mainloop()
if __name__ == '__main__':
main()
There are a number of errors in your code and previously I closed it after picking one of them and marking it as a duplicate of another question that had been asked and answered before that covered that problem.
However, based on comments you made and after thinking it over, I decided to reopen it and attempt to address all or at least most of the issues I saw — otherwise it would likely have taken you quite a while to get everything fixed.
Here's the result:
from PIL import ImageTk, Image
import tkinter as tk
class ImageViewer:
def __init__(self, root, image_filename):
self.root = root
self.image_filename = image_filename
self.root.title('ImageViewer')
self.root.geometry('400x350')
self.canvas = tk.Canvas(self.root, width=300, height=300)
self.canvas.place(x=10, y=10)
self.btnView = tk.Button(text='View', command=self.view_image)
self.btnView.place(x=20, y=265)
self.btnClose = tk.Button(text='close', command=self.root.destroy)
self.btnClose.place(x=65, y=265)
def view_image(self):
self.img = ImageTk.PhotoImage(Image.open(self.image_filename)) # Keep ref to image.
self.canvas.create_image(20, 20, anchor=tk.NW, image=self.img)
def main(image_filename):
root = tk.Tk()
ImageViewer(root, image_filename)
root.mainloop()
if __name__ == '__main__':
main(r"C:\Users\SteveSmith\eclipse-workspace\SteveSmith-ex1\src\raw\pythonIsFun.jpg")
