Re: how to replace a child of a GtkBox ?

[Micah Carrick <email micahcarrick com>]

gtk_notebook_get_tab_label() will get the widget. That will give you the reference to your GtkHBox. You can 
then get the pointer to the GtkImage (assuming image is first child) from the children GList of the GtkBox. 
Just off my head, maybe something like...

GtkWidget *box, *image;

box = gtk_notebook_get_tab_label (GTK_NOTEBOOK (notebook));
image = GTK_WIDGET (g_list_first(box->children)->data); 
gtk_image_set_from_file (GTK_IMAGE (image), "new-image.png");
