Re: How to manage a window flowing over another?

At first, I should express my thank to Havoc Pennington. This is the second
time you help me. Thanks.

Yes, I should use GTK_WINDOW_DIALOG as the first window, and set the second
one transient for it. What is important is to realize the first one before I
use gdk_window_set_decorations. Or, it will give us a warning as "assert on
`window!=NULL` failed".

But I want to know WHEN  should I realize a widget? I seldom realize a
widget. Of course it give me many warnings when it runs in return.
