Scrollbars on canvas - Christina - Sep-13-2019 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): 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 RE: Scrollbars on canvas - woooee - Sep-14-2019 Use the ScrolledFrame from Pmw http://pmw.sourceforge.net/doc/ScrolledFrame.html or PyPi https://pypi.org/project/tkScrolledFrame/ RE: Scrollbars on canvas - Christina - Sep-14-2019 woooee thank you for your advice. tkScrolledFrame works in my app. |
