Answer 1

Note: this is Windows specific. This focuses the whole main window. Essentially forcing an alt-tab to reach the window.

None of these answers worked for me, the tk window would appear on top of everything with the -topmost flag, my input box would have focus, but the window itself wouldn't, which meant that typing wouldn't appear in the tk window. It looks like like this:

What helped was adding a call to the Windows API to steal focus:

import win32gui    
root = tk.Tk()

# Application specific setup ...

win32gui.SetForegroundWindow(root.winfo_id())

Disclaimer: Stealing focus is bad behaviour, so only use it if you must and if it makes sense, e.g. input box the user will instantly type into.
