One way is to define the deletion callback for the text's parent window to
get the text before the widget gets deleted. To do that, you can use
text.winfo_toplevel() to get the parent Toplevel for your text widget,
then define the callback via wdw.protocol('WM_DELETE_WINDOW', ...). Here
is a detailed example:
-----------------------------------------------------
from Tkinter import *
root = Tk()
txt = None
def openWdw():
global txt
wdw = Toplevel()
frm = Frame(wdw)
frm.pack(expand=1)
txt = Text(frm)
txt.pack()
print txt.winfo_toplevel(), frm, root
txt.winfo_toplevel().protocol('WM_DELETE_WINDOW', getText)
def getText():
print txt.get(1.0, END)
txt.winfo_toplevel().destroy()
Button(root, text='Go', command=openWdw).pack()
root.mainloop()
-----------------------------------------------------
This will of course only work if the only reason for which the text widget
can be destroyed is if its parent window is closed.
