如何正确地将 tkinter 指向不同文件夹中的图像？

Question

I am creating a tkinter application in which I am using custom button images, along with a custom button class in order for the button to have a hovering effect. The script was working fine when the images and scripts were in the same folder, however, as soon as I tried using the "os" or "path" module, python gives me this error.

"_tkinter.TclError: image "N:\\Year 13\\Computer Science\\Project\\AMFC\\Project files/Buttons/App button.gif" doesn't exist"

I made sure that the image is actually existent in the path, and I tried building the path based on the "os.getcwd()" and "os.path.join" as well as the "path" module equivalent. I also tried building the absolute path to the image, however, it still didn't work.

work_folder = os.path.dirname(os.path.abspath(__file__))
button_path = os.path.join(work_folder, "Project files/Buttons")

Here is my custom button class:

class Button(tk.Button):
    def __init__(self, parent, default_background="", hover_background="", **kwargs):
        tk.Button.__init__(self, master=parent, **kwargs)
        self.default_background = tk.PhotoImage(file=default_background)
        self.hover_background = tk.PhotoImage(file=hover_background)
        self.configure(image=self.default_background)
        self.bind("<Enter>", self.on_enter)
        self.bind("<Leave>", self.on_leave)

    def on_enter(self, event):
        self.configure(image=self.hover_background)

    def on_leave(self, event):
        self.configure(image=self.default_background)

Here is how I apply it:

import Customised_Widgets as cw    

cw.Button(self, text="Pure Core", default_background=os.path.join(button_path, "App button.gif"),
              hover_background=os.path.join(button_path, "Project files/Buttons/App button(hover).gif"),
              relief=tk.FLAT,highlightcolor="#E7E6E6",highlightbackground="#E7E6E6",
              bg="#E7E6E6", bd=0, padx=0, pady=0, borderwidth=0,
              highlightthickness=0, compound="center").place(x=434, y=270) 

I created the button in a separate module in order to keep my work more organised. This separate module is in the same folder as the main script.

I don't know what to do, I tried giving the full path name to the image, it still didn't work. It refuses to detect the image in the folder that I point tkinter to, even though it does exist...

Any help would be appreciated.

You shouldn't use the Separator characters in the os.path.join . This method will use the correct separator for your path. It is different on different Operation systems (For Windows , it's '\\' and for Unix it's '/'). Furthermore you can write a cross-platform software with this solution.

You should try the following implementation:

os.path.join(button_path, "Project files", "Buttons", "App button(hover).gif")
