New submission from Jeffrey Goeders:
I am experiencing a crash when calling focus_get() when a Tk Menu has focus.
Here is sample code, just click the menu and it will crash.
import Tkinter as tk
class App(tk.Tk):
def __init__(self, *args, **kw):
tk.Tk.__init__(self, *args, **kw)
self.entry = tk.Entry(self)
self.entry.grid(padx=20, pady=20)
self.entry.focus_set()
self.entry.bind("<FocusOut>", self.entry_focus_lost)
self.menubar = tk.Menu(self)
self["menu"] = self.menubar
self.menufile = tk.Menu(self.menubar, tearoff=False)
self.menubar.add_cascade(menu=self.menufile, label="File")
def entry_focus_lost(self, event):
widget_with_focus = self.focus_get()
app = App()
app.mainloop()
Here is the error stack:
Exception in Tkinter callback
