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?

the way to do this is via a callback function: with sys_vgui you call a function in the pd-gui process, which then can send back a message to a pd; you have to bind your object to a special receiver to receive this message.

you will also be able to receive this message via a [r <special receiver>] object, there is no way to do an exclusive communication.
