I suspect that the difference is that your tclkit is functionally a "wish", whereas I'm running in "tclsh" and doing "package require Tk". As for using Tk in multiple threads--all of the documentation I've seen on the Threads package that mentions Tk (as, for example, _Practical Programming in Tcl and Tk_) says not to do it. It's not that it will fail immediately, but that it (under circumstances usually difficult to reproduce or debug) it will fail mysteriously. Will -- Will Duquette -- Wil...@jp...

Also, I didn't have to do any kind of thread::wait or anything like that, seems to work OK as is with the setup I have (which is using a tclkit with the thread libraries built in) See attached script On 11/1/2011 4:36 PM, Duquette, William H (318K) wrote: Howdy! Two questions: 1. I know that I can only use Tk in a single thread of a multi-threaded app. Does it matter which thread it is, i.e., if Tk is NOT running in the main thread is it OK to invoke it in a thread created using thread::create? (I've tried it; it appears to work; I just need to know whether it will cause me problems in the long run.) 2. When I invoke Tk using [package require Tk] in a thread created using thread::create, it appears that I have to call [vwait] or [thread::wait] explicitly at the end of the thread startup script, or I don't enter the event loop. Is this expected behavior? Thanks very much!
