How can I set a style for treeview widgets so that alternate rows have different background colors, for example, rows 1,3,5 have white backgrounds and rows 2,4,6 have light blue-grey backgrounds? I'd also like to set gridlines . Matt Fenwick I had this same issue a few months ago. From the tk docs : You can assign a list of tags to each item using the "tags" item configuration option (again, when creating the item or later on). Tag configuration options can then be specified, which will then apply to all items having that tag. Basically, you apply one tag to all of the odd-numbered rows, a

I have a problem to set background color for Combobox using tkinter ttk with 'vista' theme (I'm using Python 3). I've tried code from here ttk.Combobox glitch when state is read-only and out of focus import tkinter as tk from tkinter import ttk root = tk.Tk() combo = ttk.Combobox(root, values=['1', '2', '3']) combo['state'] = 'readonly' combo.pack() tk.Entry(root).pack() style = ttk.Style() style.map('TCombobox', selectbackground=[('readonly', 'red')]) #style.map('TCombobox', fieldbackground=[('readonly', 'blue')]) #not working as well But this will change only background for text, rest part

For example, lets create a Treeview widget using a class as follows: class FiltersTree: def __init__(self, master, filters): self.master = master self.filters = filters self.treeFrame = Frame(self.master) self.treeFrame.pack() self._create_treeview() self._populate_root() def _create_treeview(self): self.dataCols = ['filter', 'attribute'] self.tree = ttk.Treeview(self.master, columns = self.dataCols, displaycolumns = '#all') Populate root, insert children as usual. At the end of the codeblock, you can see where I want to put a Combobox in the tree, using a Combo object: def _populate_root(self

I am building an application that embeds a matplotlib figure into the GUI. The problem is that my app is crashing as soon as I add anything from matplotlib into my code (except for the imports, those work as usual). The problem occurs in my class Solver_App at tk.Tk.__init__(self, *args, **kwargs) . When I run the code, I get a massive error and the app crashes. Here is some of my code: import tkinter as tk from tkinter import ttk import matplotlib from matplotlib import pyplot as plt from mpl_toolkits.mplot3d import Axes3D from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg,
