This was written by me a long long time ago ;)) Now, I've been working
again on it.

Helmethead told me to do it using 
pixmap = gdk_pixmap_colormap_create_from_xpm_d (NULL,
gtk_widget_get_default_colormap(),&mask, NULL, xpm_structure);

I used it, and it seems to work fine, the problem is i'm using C++ (yes
yes.. don't tell me to use the Gtk-- again, I already know ;)) and I'm
getting a Segmentation fault  when trying to assign the GdkPixmap
*pixmap returned by "gdk_pixmap_colormap_create_from_xpm_d()" to my
"GdkPixmap& pix" parameter..
Here is my C++ function... 

gboolean ParameterKernel::ReadPixmap(gchar **pixstring, GdkPixmap& pix)
//Reads a pixmap from a xpm-format string & stores it in GdkPixmap& pix
  GdkPixmap *pixmap;
  GdkBitmap *mask;

  pixmap = gdk_pixmap_colormap_create_from_xpm_d (NULL,
  						&mask, NULL, (gchar **) pixstring);

  g_print("The program arrives this point\n");
  (GdkPixmap *) pix =  pixmap;
  g_print("Segmentation fault is in the line above\n");
  if (&pix == NULL) {return (FALSE);} else {return (TRUE);}


...any idea about what can be wrong?

Thanks in advance,
