Creating pixmap (GtkPixmap *pixmap)

[Joana Bendoraityte <mergaite_lietuvaite yahoo de>]

Hi,

can anybody to help?  
I need create the pixmap (GtkPixmap *pixmap). 
I do:


GtkWidget *myFunction(Uint8 *imgRGB, Uint32 w, Uint32
h)
{
   GtkStyle *style;
   GdkBitmap *bitmap;
   GdkPixmap *pixmap_gdk ;
   GtkWidget *drawing_area;
   GtkWidget *pixmap;
                   
   if (imgRGB == NULL)
        {
            return NULL;
        }

    drawing_area = gtk_drawing_area_new();
    gtk_object_set_data(GTK_OBJECT(drawing_area),
"drawing_area", drawing_area);
 
gtk_drawing_area_size(GTK_DRAWING_AREA(drawing_area), 
300, 300);
    gtk_widget_show(drawing_area);

    style = gtk_widget_get_default_style();
    pixmap_gdk = gdk_pixmap_create_from_xpm_d(
drawing_area->window, &bitmap,
&style->bg[GTK_STATE_NORMAL], &imgRGB );

    if (pixmap_gdk == NULL) 
    { 
        printf("pixmap is empty\n");
        return(NULL); 
    }
    
     pixmap = gtk_pixmap_new(pixmap_gdk, bitmap);

    return pixmap;
}

but pixmap_gdk is NULL... -> pixmap is NULL to.

Thanks & Regards
Joana
