New submission from Terry J. Reedy:
PyShell currently has this code
try:
from tkinter import *
except ImportError:
print("** IDLE can't import Tkinter.\n"
"Your Python may not be configured for Tk. **", file=sys.__stderr__)
sys.exit(1)
import tkinter.messagebox as tkMessageBox
When Idle is started from an icon, there is no place for the error message to
go, so it appears than nothing happens. But this is the best we can do without
invoking system specific error message functions. (This, if possible, would be
another issue.) The second import assumes that messagebox is available, which
is should be without modification of the tkinter package since long ago. But I
think we should guard against someone trying to start Idle on pre 8.5. The
following seems to work nicely. This is a prerequisite for any ttk patches.
Any comment before I apply?
try:
from tkinter import ttk
except:
root = Tk()
root.withdraw()
tkMessageBox.showerror("Fatal Idle Import Error",
"Idle cannot import required module tkinter.ttk.\n"
"Click OK to exit.",
parent=root)
sys.exit(1)
