All geometry manager methods that apply to a master widget instead of
to a slave widget have been moved to the Misc class, which is
inherited by all of Tk(), Toplevel() and Widget(). They have been
renamed to have their geometry manager name as a prefix,
e.g. pack_propagate(); the short names can still be used where
ambiguities are resolved so that pack has priority over place has
priority over grid (since this was the old rule).
Also, the method definitions in the Pack, Place and Grid classes now
all have their respective geometry manager name as a prefix
(e.g. pack_configure); the shorter names are aliases defined through
assignment.
A similar renaming has been done for all config() methods found
elsewhere; these have been renamed to configure() with config being
the alias (instead of the other way around). (This may not make much
of a difference but the official Tk command name is now 'configure'
and it may help in debugging tracebacks.)
Finally, a new base class BaseWidget has been introduced, which
implements the methods common between Widget and Toplevel (the
difference between those two classes is that Toplevel has a different
__init__() but also that Toplevel doesn't inherit from Pack, Place or
Grid.
was all that the method set anyway). Removed calls to the
constructor. This reduces the number of Python function calls
per widget construction by one, for every widget construction.
not exist. All 8 uses of tkinter are replaced with _tkinter. Still
create a variable tkinter though, because that is used by other
modules importing Tkinter (e.g. tkinter.createfilehandler()).
Also added a comment to the 'import _tkinter' line saying that if this
fails, Python is not configured correctly.
to Frame(w, cnf={"class": "classname"}). I think this is the only
widget other than Toplevel that needs to be concerned about setting
the widget's class (-class must be the first option on the Tcl
widget creation command).
Tk 4.2. The new winfo options supported are: mananger, pointerx,
pointerxy, pointery, server, viewable, visualid, visualsavailable.
Also fixed bugs in winfo_colormapfull() and winfo_containing().
selection interface, handle the -displayof option intelligently in
many places. Added "wm colormapwindows" and "winfo colormapfull"
support. Removed "focus default" and "focus none" method: these are
not in Tk 4.X.
