comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").
There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)
this patch adds a fast _flatten function to the _tkinter
module, and imports it from Tkinter.py (if available).
this speeds up canvas operations like create_line and
create_polygon. for example, a create_line with 5000
vertices runs about 50 times faster with this patch in
place.
OptionMenu is modified. Somewhat rewritten and elaborated by myself.
class _setit: The constructor now takes an optional argument
`callback' and stashes this in a private variable. If set, the
__call__() method will invoke this callback after the variable's value
has changed. It will pass the callback the value, followed by any
args passed to __call__().
class OptionMenu: The constructor now takes keyword arguments, the
only one that's legally recognized is `command', which can be set to a
callback. This callback is invoked when the OptionMenu value is set.
Any other keyword argument throws a TclError.
and Toplevel class constructors. This means that if the window
manager closes the window, the Python-side Tkinter data structures
will be destroyed correctly. (Most apps do this anyway, and it's
recommended practice; I see no reason why making it the default
behavior could be bad.)
bindings to a dictionary _tagcommands which was otherwise unused.
(This was checked in accidentally with rev. 1.125 and not deleted with
rev. 1.127 when the other half of this code was removed -- although
even as originally checked in the _tagcommands variable was never
used.)
(PR#40, reported by Peter Stoehr)
than was worth it: when deleting a canvas item, it would try to
automatically delete the bindings for that item. Since there's
nothing that says you can't reuse the tag and still have the bindings,
this is not correct. Also, it broke at least one demo
(Demo/tkinter/matt/rubber-band-box-demo-1.py).
so the preferred name for them is tag_lower, tag_raise
(similar to tag_bind, and similar to the Text widget);
unfortunately can't delete the old ones yet (maybe in 1.6)
An attempt to execute grid_slaves with arguments (0,0) results in
*all* of the slaves being returned, not just the slave associated with
row 0, column 0. This is because the test for arguments in the method
does not test to see if row (and column) does not equal None, but
rather just whether is evaluates to non-false. A value of 0 fails
this test.
in autoexec.bat in order to find the Tcl DLLs -- Tkinter calls FixTk
which will hunt around in a few common places and then set PATH
and try again, or else issue a big clarifying error message.
assign the exception info to sys.last_{type,value,traceback}. That
way, an introspective Tkinter app can inspect its own stack trace.
(The controversy is that it would keep some objects alive, but that's
probably no big deal.)
Fix bug in NoDefaultRoot() -- _default_root wasn't declared global;
and made it reentrant.
Don't set _default_root to whatever master gets passed in to
BaseWidget._setup() (only set it when we need to create a new Tk()
widget).

the "initialcolor" code is broken in several places in the
current version of tkColorChooser. I've attached an up-
dated version for 1.5.2.
