Yes I tried the same, but I have a little bit other problem:

GtkWidget *window;
GtkWidget *scrolled_win;
GtkWidget *vbox;
int w,h;

scrolled_win added to window and vbox added to scrolled_win.
Now, I added some buttons,... to vbox.
When my programm start's up the window should be large enought
that the scrollbars are not needed and not visible.
So I tried it that way:

gtk_widget_show_all( window );

w = vbox->allocation.width;
h = vbox->allocation.height;

w = w + GTK_CONTAINER( vbox )->border_width * 2;
h = h + GTK_CONTAINER( vbox )->border_width * 2;

w = w +
GTK_WIDGET(GTK_SCROLLED_WINDOW(scrolled_win)->vscrollbar).allocation.width
h = h +
GTK_WIDGET(GTK_SCROLLED_WINDOW(scrolled_win)->hscrollbar).allocation.width
 
gtk_window_set_default_size( GTK_WINDOW( window ), w, h);

This works, but if the border_width of vbox is less then 4, the
window is'nt big enought, and the scrollbars are still visible.

Is there a better way?
