Category: Tkinter Group: None >Status: Closed >Resolution: Fixed Priority: 5 Submitted By: Thomas Wouters (twouters) Assigned to: Martin v. Löwis (loewis) Summary: Tkinter hangs in test_tcl Initial Comment: For a while now, I've noticed test_tcl locking up when trying to refleaktest it. I was able to reproduce it quite simply: import Tkinter, os if "DISPLAY" in os.environ: del os.environ["DISPLAY"] tcl = Tkinter.Tcl() try: tcl.loadtk() except Exception, e: print e tcl.loadtk() Or using _tkinter directly: import _tkinter, os if "DISPLAY" in os.environ: del os.environ["DISPLAY"] tk = _tkinter.create(None, "test", "Tk", 0, 1, 0) try: tk.loadtk() except: pass tk.loadtk() In either case, the second loadtk never finishes. It seems that, on my platform at least, Tk_Init() doesn't like being called twice even when the first call resulted in an error. That's Tcl and Tk 8.4.12. Tkapp_Init() (which is the Tkinter part that calls Tk_Init()) does its best to guard against calling Tk_Init() twice when the first call was succesful, but it doesn't remember failure cases. I don't know enough about Tcl/Tk or Tkinter to know how this is best handled. ---------------------------------------------------------------------- >Comment By: Martin v.
