in python i need to create a gui program that opens a image browser for my hard disk. the program needs to load a scrolling list box with filenames of images in cwd, names of subdirectories in the cwd, and the string ".." denoting the parent directory. the pathname of the cwd should also be displayed in an entry feild. when the user selects an item in the list box and presses the go button if the item is an image filename the image should be displayed, if the item is a subdirectory the program attaches to that directory and refreshes the list box contents. if the item is the string ".." the program attaches to the parent directory and refreshes the list box with its content. full code please not that picture because i do not understand it and really need help with this. thank you
