I have a main window open. I don’t want to close this window. (which seems to be in most of these questions).

when I click on a button a small window opens under the mouse position. I want this second window to close when either one of its buttons are pressed or after the mouse moves away.

My problem is when I go into a function from either of the above actions I do not seem to have a reference to close this window. as in ‘alt.destroy’

My thought is to use the mouse moves away option as it should cover all needs.

Here is a sample code of what I am trying to do.

from tkinter import * 
backGd='#333333'
FrGd='white'
def AlignmentTypes():
    alt_x_y=ListWinStartPsn()       
    alt = Tk()
    alt.geometry(f"100x150+{alt_x_y[0]}+{alt_x_y[1]+20}")
    #alt.configure(bg=backGd)
    alt.bind("<Leave>", closeAltWin)

    Titlelabel=Label(alt, text="Select Alignment Type",bg=backGd,fg=FrGd)
    alLeft_btn=Button(alt,text="Align Left",fg="Dark Blue",width=11)
    alCenter_btn=Button(alt,text="Align Center",fg="Dark Blue",width=11)
    alRight_btn=Button(alt,text="Align Right",fg="Dark Blue",width=11)
    alJustify_btn=Button(alt,text="Align Justify",fg="Dark Blue",width=11)
        
    Titlelabel.pack()
    alLeft_btn.pack()
    alCenter_btn.pack()
    alRight_btn.pack()
    alJustify_btn.pack()

def ListWinStartPsn():
    x, y = btn1.winfo_rootx(), btn1.winfo_rooty()
    return(x,y)

def closeAltWin(event):
    pass
    #alt.destroy

root = Tk()
root.title('Workopedia')
root.geometry('500x300')


frame1=Frame(root)
frame1.pack()
btn1=Button(frame1,text="click",command=AlignmentTypes)
btn1.pack()
frame2=Frame(root)
frame2.pack()
lbl1=Label(frame1,text="Stuff")
lbl1.pack()

root.mainloop()
