| Calls to the widget method tk_focusNext() fail with "unsubscriptable object" error. Looking at the Tkinter.py code for the routine shows this statement: name = self.tk.call('tk_focusNext', self._w) (line 433) which used to return a string in 2.2 but now returns a "cmdName object". When this is passed to self._nametowidget(name), it fails when it tries to subscript name (line 1006) since the object does not support indexing. Perhaps str(name) or name.string is more appropriate now? (when that change is made, it works--well, I tested name.string and that worked) Perry Greenfield (perry@stsci.edu) |

| Logged In: YES user_id=2772 Presumably, _nametowidget() should be modified to work properly with a "cmdName object", rather than modifying each site that gets a widget path from a tk command. |

| Logged In: YES user_id=692511 The problem is still not resolved for now (AFAIK). Here is a very simple patch for Tkinter.py: *** 432,442 **** --- 432,446 ---- to 0.""" name = self.tk.call('tk_focusNext', self._w) if not name: return None + try: name=name.string + except: pass return self._nametowidget(name) def tk_focusPrev(self): """Return previous widget in the focus order. See tk_focusNext for details.""" name = self.tk.call('tk_focusPrev', self._w) if not name: return None + try: name=name.string + except: pass return self._nametowidget(name) def after(self, ms, func=None, *args): """Call function once after given time. Note: I have made this (try/except) cause I have encountered cases where "name" was still a string (well, at least with Python 2.3.1). David (david.douard*gmail.com) |

| This problem still persists, at least in Python 2.4. As noted by Perry Greenfield, the same problem occurs in tk_focusPrev, and some other methods as well. Rather than track down all such calls it would be easier to add the line name = str(name) at the top of the nametowidget method. Rick Litherand. lither@math.lsu.edu |
