Hello,
I'm trying to create a image viewer in tkinter. I have problem with scrollbars in my app. I want horizontal and vertical scrollbars next to image when the image is zoomed. I use following code to do this (part of my code):
In what part of the code do I have a mistake?
Thank you, Christina
I'm trying to create a image viewer in tkinter. I have problem with scrollbars in my app. I want horizontal and vertical scrollbars next to image when the image is zoomed. I use following code to do this (part of my code):
image = Image.open(filename)
photo = ImageTk.PhotoImage(image)
...
if zoom > 1:
canvas = Canvas(root, width = w*zoom, height = h*zoom, bg=bgcolor)
canvas.pack(side="top", expand=1, fill=BOTH)
scroll_bar_x = Scrollbar(canvas, orient = tkinter.HORIZONTAL)
scroll_bar_x.pack(side="bottom", fill = X, expand= 0)
scroll_bar_y = Scrollbar(canvas, orient = tkinter.VERTICAL)
scroll_bar_y.pack(side="right", fill = Y, expand= 0)
scroll_bar_x["command"] = canvas.xview
scroll_bar_y["command"] = canvas.yview
canvas["xscrollcommand"] = scroll_bar_x.set
canvas["yscrollcommand"] = scroll_bar_y.set
canvas.create_image(w*zoom/2, h*zoom/2, image=photo)I see scrollbars next to image but they don't work. I can't use them.In what part of the code do I have a mistake?
Thank you, Christina
