Hi, based on this documentation of GnomeCanvas, http://library.gnome.org/devel/libgnomecanvas/stable/GnomeCanvas.html#GnomeCanvas--aa you can pass this property in construction time, which I believe means in call of g_object_new, and because ECanvas is the specialization of the GnomeCanvas, then the GnomeCanvas will set this property, same as it does in gnome_canvas_new_aa: http://svn.gnome.org/viewvc/libgnomecanvas/trunk/libgnomecanvas/gnome-canvas.c?revision=1286&view=markup Hope that helps, Milan ___ Evolution-hackers mailing list Evolution-hackers@gnome.org http://mail.gnome.org/mailman/listinfo/evolution-hackers
Re: [Evolution-hackers] e_canvas_new in Evolution
Hi Milan
Thanks for your prompt reply,
"aa" is not a member of the ECANVAS structure ;
In gnome_canvas_new_aa() function "aa" is a member of the Gnome_canvas
structure , defined as below
/* Whether the canvas is in antialiased mode or not */
unsigned int aa : 1;
And the link below gives us the details of the two modes of gnome canvas
operation
http://developer.gnome.org/doc/GGAD/z177.html
So making the "aa" modification; will it understand as to what is to be
done?
Are these two modes supported in Ecanvas ?
what do you suggest ?
Thanks & Regards
sv.

Hi,
based on the code, ECanvas is a descendant of the GnomeCanvas. I would
suggest, for testing, changing e_canvas_new from:
GtkWidget *
e_canvas_new (void)
{
return GTK_WIDGET (g_object_new (E_CANVAS_TYPE, NULL));
}
to
GtkWidget *
e_canvas_new (void)
{
return GTK_WIDGET (g_object_new (E_CANVAS_TYPE,
"aa", TRUE, NULL));
}
or something like that.
For calling redraw, you can do it in a same way as for GnomeCanvas.
Bye,
Milan
