Grab on TkToplevel window

ruby-talk
1

Hello,
I’m using Tk for the first time and had this problem that I cannot
solve.
Is it possible to grab a toplevel window like a dialog box?
I have something like this:
window=TkToplevel.new
window.grab

and I get this message:
Error:/usr/lib/ruby/1.8/tk.rb:1623:in `__invoke’: grab failed: window
not viewable

As an alternative I can use a dialog box, but I need to return a
string from the user. Is it possible to put a TkEntry in a dialog box?
How?

Thanks for your time.

Probably there are two effective ways.

(1) window = TkToplevel.new
Tk.update
window.grab

(2) window = TkToplevel.new
window.wait_visibility
window.grab

Worked, thanks a lot.

(2) window = TkToplevel.new
window.wait_visibility
window.grab

I get the same error with this one
