ttk

问题 I am trying to disable all of the (ttk) widgets in a frame, but it appears that the scale widget is giving me some trouble, as it throws the following exception: _tkinter.TclError: unknown option "-state" Some relevant code: import tkinter as tk from tkinter import ttk def disable_widgets(parent): for child in parent.winfo_children(): child.config(state = 'disabled') root = tk.Tk() # Frame full of widgets to toggle frame_of_widgets = ttk.Frame(root) frame_of_widgets.pack() # Button to be

问题 I need to create a custom style for button widgets which has the same appearance as buttons using the ttk 'clam' theme. I can set the theme like: s = ttk.Style() s.theme_use('clam') However, given the nature of a theme, this will then set all ttk widgets to use 'clam'. I would like to be able to set certain ttk buttons to use the clam appearance and others to use default ttk. I have tried looking at the layouts and configurations of 'TButton' whilst the clam theme is in use but it seems that

问题 I would like to know the command for collapsing and expanding a branch in ttk.Treeview. Here is a minimalistic example code: #! coding=utf-8 import tkinter as tk from tkinter import ttk root = tk.Tk() tree = ttk.Treeview(root) tree.pack(fill=tk.BOTH,expand=True) tree.insert("", index="end",iid="Main", text="main branch") tree.insert("Main", index="end", text="Stuff 1") tree.insert("Main", index="end", text="Stuff 2") root.mainloop() What command opens and/or expands the "main branch"? There

问题 I have been attempting to make a directory browser for a recent project of mine that I'm developing in python 3.4.4 with tkinter. I do not want the background to be the default color, so I have gone about changing the background of most widgets. I didn't have any trouble until I got to the Treeview. I'm not too good with ttk.Style(), but I still managed to get ttk.Style().configure("Treeview", background="black", foreground="white") to work, however this only changes the background of the
