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
