[New-bugs-announce] [issue37546] colors in ttk treeview tags are ignored

[dave]

New submission from dave <dave9000 at cheapnet.it>:

The following example code fails in Python 3.7.3 64 bit (both lines are displayed in black).
It works correctly in 3.7.2 and earlier.

import tkinter as tk
import tkinter.ttk as ttk

root = tk.Tk()

ttk.Label(root, text='This is a RED label', foreground='red').pack()

tree = ttk.Treeview(root)
tree.tag_configure('RED_TAG', foreground='red', font=('arial', 12))
tree.insert('', tk.END, text='Black line')
tree.insert('', tk.END, text='Red line', tag='RED_TAG')
tree.pack()

root.mainloop()
