gtk_print_operation_new & g_signal_connect_data is not calling the Closure function

["Rodrigo Miguel" <rodrmigu gmail com>]

Hello All,

I don't know if that is the normal behavior, but some reason the
GClosureNotify function is not being called when used with
gtk_print_operation pointer.

Here is the sample that I used:

#include <math.h>
#include <pango/pangocairo.h>
#include <gtk/gtk.h>
#include <gtk/gtkprintoperation.h>

void test(gpointer data)
{
    g_print("Not through here!\n");
}


static void
draw_page (GtkPrintOperation *operation,
           GtkPrintContext *context,
           int page_nr)
{
  cairo_t *cr;
  PangoLayout *layout;
  PangoFontDescription *desc;

  cr = gtk_print_context_get_cairo_context (context);

  cairo_set_source_rgb (cr, 1.0, 0, 0);
  cairo_rectangle (cr, 0, 0, gtk_print_context_get_width (context), 50);

  cairo_fill (cr);

  cairo_move_to (cr, 20, 10);
  cairo_line_to (cr, 40, 20);
  cairo_arc (cr, 60, 60, 20, 0, G_PI);
  cairo_line_to (cr, 80, 20);

  cairo_set_source_rgb (cr, 0, 0, 0);
  cairo_set_line_width (cr, 5);
  cairo_set_line_cap (cr, CAIRO_LINE_CAP_ROUND);
  cairo_set_line_join (cr, CAIRO_LINE_JOIN_ROUND);

  cairo_stroke (cr);

  layout = gtk_print_context_create_pango_layout (context);
  pango_layout_set_text (layout, "Hello World! Printing is easy", -1);
  desc = pango_font_description_from_string ("sans 28");
  pango_layout_set_font_description (layout, desc);
  pango_font_description_free (desc);

  cairo_move_to (cr, 30, 20);
  pango_cairo_layout_path (cr, layout);

  cairo_set_source_rgb (cr, 0.93, 1.0, 0.47);
  cairo_set_line_width (cr, 0.5);
  cairo_stroke_preserve (cr);

  cairo_set_source_rgb (cr, 0, 0.0, 1.0);
  cairo_fill (cr);

  g_object_unref (layout);
}


int
main (int argc, char **argv)
{
  GtkPrintOperation *print;
  GtkPrintOperationResult res;

  gtk_init (&argc, &argv);

  print = gtk_print_operation_new ();
  gtk_print_operation_set_n_pages (print, 1);
  gtk_print_operation_set_export_filename (print, "test.pdf");

  /************************/
  g_signal_connect_data(print, "draw_page", G_CALLBACK (draw_page),
NULL, (GClosureNotify) test, (GConnectFlags) 0);
  /************************/

  res = gtk_print_operation_run (print,
GTK_PRINT_OPERATION_ACTION_EXPORT, NULL, NULL);

  return 0;
}


Any Ideas or comments?

Thanks in advance
Rodrigo
