You are supposed to use it with canvas_unsetcurrent (alias of pd_popsym), though I don't remember what can really go wrong if you don't unset/pop. Lots of stuff goes wrong if you don't call canvas_unsetcurrent after setting it. :) I know because I was running into all sorts of EXC_BAD_ACCESS signals before doing it - specifically in some experiments in opening patches via x_canvas points. Thanks for the tip, Mathieu. I actually got a couple other questions now that I have figured out a bit more, but I'll save it for another thread..

In all cases, you need to get a canvas environment (there is one per file loaded, that is, one per distinct value of $0) : t_canvasenvironment *e = canvas_getenv(x-parent); but you need to have a variable in your struct for accessing your parent : t_canvas *parent; that you need to set in the creator (constructor) because that's the only time you can obtain that information : x-parent = canvas_getcurrent(); but when you need to get the $0, you need the e and you use this : e-ce_dollarzero and if you need to get $1, $2, $3, ... you use these : e-ce_argv[0] /* $1 */ e-ce_argv[1] /* $2 */ e-ce_argv[2] /* $3 */ ... but you don't use indices that are = e-ce_argc, which is the number of arguments. ___ | Mathieu Bouchard tél: +1.514.383.3801 Villeray, Montréal, QC ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
