Ok some new information. There is an incompatibility with g_idle_add
and printing. I'm using g_idle_add for my own callback elsewhere in
the application, and if I comment that out the printing starts
working. What I think is happening is that the call to:
priv->print_pages_idle_id = gdk_threads_ad
I'm still trying to get this working.
Given this basic code:
static void begin_print(GtkPrintOperation *operation, GtkPrintContext
*context,gpointer data)
{
gtk_print_operation_set_n_pages(operation, 1);
printf("begin_print\n");
}
static void draw_page(GtkPrintOperation *operation,
