RE: drawing graphics

yo all
About back pixmap i have a  question, i did all u told and now it works like

a Ferrari engine :D
however each time i want to set a new back pixmap i write these few lines

GdkPixmap *pixmap = NULL;
 
w=(GtkWidget*)gtk_object_get_data(GTK_OBJECT(((Formulaire*)data)->GetMainWin
dow()),"drawingarea1");
pixmap=gdk_pixmap_new (w->window,
w->allocation.width,w->allocation.height,-1);
...
//here i draw onto pixmap
...
gdk_window_set_back_pixmap(w->window,pixmap,0);

thus i think it s a bit dirty... because i don t clear the previous drawing
area back buffer!!
how can i get a pointer to that back buffer 
i know i could use a global variable but...
; i didn t find gdk_window_get_back_pixmap  :P
any idea? 

thanks

regards
