>There are a couple of ways to find the top level parent
of a widget. The easiest way is to call the
<TT
CLASS="LITERAL"
>gtk_widget_get_toplevel()</TT
> function that
returns a pointer to a GtkWidget that is the top level
window.</P
><P
>A more complicated way to do this (but less limited, as
it allows the user to get the closest ancestor of a known type) is to use
<TT
CLASS="LITERAL"
>gtk_widget_get_ancestor()</TT
> as in:</P

><P
>Since virtually all the GTK_TYPEs can be used as the
second parameter of this function, you can get any parent
widget of a particular widget. Suppose you have an hbox which
contains a vbox, which in turn contains some other atomic
widget (entry, label, etc. To find the master hbox using the
<TT
CLASS="LITERAL"
>entry</TT
> widget simply use:</P

>You can also follow the a widgets ancestry by using the function
<TT

>gtk_widget_get_parent()</TT

to a widgets parent widget.</P
