I had the impression that tkinter is single threaded, but it seems
that the breakpoint() or input()
does not block the mainloop to continue
If one clicks the second button that waits for an input or enter in
the breakpoint()
the mainloop is still responsive while it waits for an input. So one
can click any button
the first to display the message or the second that will abort with a
message that readline cannot
be re-entered?
Why is that? What other commands can trigger such a behavior?
import tkinter as tk
def boinc():
for i in range(10):
print("boinc...")
def debug():
#breakpoint()
print("Breakpoint")
print("Input: ",end="")
s = input()
print("Entered:", s)
#-------------------------------------------------------------------------------
if __name__ == "__main__":
root = tk.Tk()
b = tk.Button(root, text="Boinc", command=boinc)
b.pack()
b = tk.Button(root, text="Debug", command=debug)
b.pack()
root.mainloop()
