[Glade-users] Loading widgets from XML file using libglade

[ajwood at theiet.org (Andrew Wood)]

Thanks thats sorted it. But how do I update the contents of a container 
on the fly. For example Ive defined the following function which is 
called when the program starts and loads the widgets from Glade no problem:

void showPage1()
{
        //load page1 from Glade and set as content in rightpanevbox
        rightpanevbox= glade_xml_get_widget(page1xml,"mainvbox");
        glade_xml_signal_autoconnect(page1xml);

        pagedisplayed = "Page1";
       
        
gtk_scrolled_window_add_with_viewport(GTK_SCROLLED_WINDOW(rightpanescrollview),rightpanevbox);
}

If however I call this function later on a second time I get that same 
error:
Gtk-CRITICAL **: gtk_scrolled_window_add_with_viewport: assertion 
`child->parent == NULL' failed

Im assuming this is because the scrolled window already has something in 
it which I first need to remove?
