Hide or close top level window when main window isn't visible

Question

Is there a way to close or preferably hide a top-level window if the main window is not visible?

I was already able to do that by checking if the minimize button had been clicked. Still, there are several ways to "minimise" a window such as going into another tab, hitting the side of the taskbar (on windows) etc…

Thanks!

You can try binding functions to <Unmap> and <Map> events of the window. Like below:

from tkinter import *


root = Tk()
root.geometry("600x300")
for _ in range(3):
    Toplevel(root)

def hide_all(event):
    # You could also call each child directly if you have the object but since we aren't tracking
    # the toplevels we need to loop throught the children
    for child in root.children.values():
        if isinstance(child, Toplevel):
            child.withdraw() # or depending on the os: 'child.wm_withdraw()'

def show_all(event):
    # You could also call each child directly if you have the object but since we aren't tracking
    # the toplevels we need to loop throught the children
    for child in root.children.values():
        if isinstance(child, Toplevel):
            child.deiconify() # or depending on the os: 'child.wm_deiconify()'

root.bind("<Unmap>", hide_all) # Fires whenever 'root' is minimzed
root.bind("<Map>", show_all) # Fires whenever 'root' is restored and shown
root.mainloop()

If this isn’t what you want, you may be able to use the <Expose> or <Visibility> events to get what you want. Link to all tkinter events: tkinter events from anzeljg
