hi list, just a question about sys_vgui() ... i'm trying to get some info about a widget on the pd canvas, but sys_vgui() is declared to retun void ... so i cannot get anything using this function ...
there is another way to run tcl/tk scripts in the pd canvas and get the returned data of this scripts? thanks, ll.
