As I see it, there are two solutions to your problems: - Display your strings differently. It may seem stupid, but there are sometimes situations where it is the best solution. Think about Apple's way of displaying full file path names in menus: they put the file base name first, then the full directory after a separator. If you have a way to do that, your problem is solved. - Don't use a Listbox to display your list, but another widget. A simple Text with no wrap option may be a solution; setting a tag with the option justify=LEFT on your whole text would do the trick. But if your lines of text should be selectable, it may not be the right solution. In this case, another widget you can use is a Canvas. It's a little trickier but can be done. Here is an example: -------------------------------------- from Tkinter import * root = Tk() cnv = Canvas(root, width=150, height=250) cnv.grid(row=0, column=0, sticky='nswe') hscroll = Scrollbar(root, orient=HORIZONTAL, command=cnv.xview) hscroll.grid(row=1, column=0, sticky='we') vscroll = Scrollbar(root, orient=VERTICAL, command=cnv.yview) vscroll.grid(row=0, column=1, sticky='ns') cnv.configure(xscrollcommand=hscroll.set, yscrollcommand=vscroll.set) xMax = 0 y = 0 for i in range(20): lbl = Label(cnv, text='Very, very long item number %s' % i) cnv.create_window(150, y, window=lbl, anchor='ne') y += lbl.winfo_reqheight() xMax = max(xMax, lbl.winfo_reqwidth()) cnv.configure(scrollregion=(150 - xMax, 0, 150, y)) root.mainloop() -------------------------------------- Putting bindings on the Label widgets created in the loop can be used to simulate the behaviour of a Listbox.
