问题 I am using the TTk.Progressbar in my app. I have scoured the net for an answer but no avail. I have the following code which is working well. But I want to change the thickness of the bar. progressbar = ttk.Progressbar(myGui, orient=HORIZONTAL, length=400, mode="determinate", variable=value_progress, ) progressbar.pack() I want the length to still be 400, but from the top of the bar to the bottom, I wish to decrease that so its half or less then half. (I want my bar on a diet, so to say) But

问题 I've been trying to configure the border colour of a widget in Tkinter, and I was wondering how to do that.... I've checked on StackOverflow, and it says that I should use the configure option and then set highlightbackgroundcolor = {insert color here} . I've tried that and nothing has worked. Can someone please show me a working sample of code so I can figure it out? 回答1: There is no way to change the border color of a widget, the border color is tied to the background color of the widget.

问题 I am trying to set colors to rows in a tkinter treeview object, using tags and tag_configure. There has been an earlier discussion on coloring rows which is rather old and seems to work no longer for Python3: ttk treeview: alternate row colors I have added a brief example. For me, all rows stay white, independent of whether I execute tag_configure prior or after the insert command. import tkinter as tk import tkinter.ttk as ttk root = tk.Tk() w = tk.Label(root, text="Hello, world!") w.pack()

问题 I have a delete function that is supposed to remove the selected item in the Combobox and its associated dictionary value.

问题 Can anyone tell me how to remove the header row in a tkinter Treeview? from tkinter import * from tkinter import ttk root = Tk() NewTree= ttk.Treeview(root) NewTree.pack() NewTree.heading("#0", text="How to remove this row?") NewTree.insert("", "0", 'item1',text='Item number 1') root.mainloop() 回答1: Use the show option to only show the tree and not the heading: NewTree = ttk.Treeview(root, show="tree") Relevant documentation From docs.python.org: show A list containing zero or more of the

问题 I have a python tkinter application that contains a ttk.treeview widget. The widget displays a list of files found on a specific directory tree with a specific extension - this was trivial to build with tt.treeview widget. There is a request to enable "on-the-fly" filtering of the tree - e.g., the user types in an Entry some string, and as he/she types, the tree removes elements that don't match the typed string so far. I was exploring the Treeview documentation, tried the detach and reattach
