New submission from Roger Serwy <roger.se...@gmail.com>:
IDLE's EditorWindow.py relies on using FileList.py's "vars" dictionary to store
Tkinter variables instead of using its own. As a consequence,
toggling a checked menu item in one editor window toggles the menu item in ALL
editor windows.
To reproduce this error, open two editor windows with Code Context initially
disabled. Enable Code Context in one window and then click "Options" in the
other. You'll see Code Context checked when it shouldn't be.
Attached is a patch to fix this problem. It causes EditorWindow to have its own
dictionary for handling these Tkinter variables instead of using the flist's
"vars". The comment in FileList.py suggests that this design is a relic from an
old version of IDLE, since getrawvar is no longer a function.
self.vars = {} # For EditorWindow.getrawvar (shared Tcl variables)
