Question

I am using tkMessageBox.showinfo (info at tutorialspoint) to popup warnings in my program.

The problem happens only when the warning is called with a second TopLevel window (apart from the main one) on screen: in this case the warning remains hidden behind the second TL window.

I tried to call it thus:

tkMessageBox.showinfo(title='Warning',message=s).lift()

but it doesnt work. Any ideas?

I think the message box is only ever guaranteed to be above its parent. If you create a second toplevel and you want a messagebox to be on top of that second window, make that second window the parent of the messagebox.

tl2 = tk.Toplevel(...)
...
tkMessageBox.showinfo("Say Hello", "Hello World", parent=tl2)
