Re: [gnome-print] Filter code for gnome-print

Dear Chema

I'm trying to add a customized reporting interface
  where    a report is generated by the package and ,  
the user will be allowed to drag and drop the texts,images etc.

 I tried to insert a lot of gnomecanvasitems  ( text ) into the canvas,  Now,
eats up a lot of memory and my program segfaults
  
     Now i guess this is because the no. of canvasitems i'm creating is too
high 
Will it be much less memory consuming if i try to write a new widget like
 ( canvas-text-box ) . This box can be later removed ..

I see that libgnomeprint has done is quite well. 
            How did u manage to do it ?
            
( or could my segfaults be due to some other problem ? )
