[PyKDE] Call for ideas - more operators for Qt Widgets

[Torsten Marek]

Hello pythonistas,

in agreement with Phil, I want to ask YOU what operators you want for Qt 
widgets in PyQt.
By now, all reasonable operators for QPoint, QRect, QString, QSize, 
QRegion and QWMMatrix have been implemented and are in the current 
snapshots or still under testing, so please do not recommend any of 
those classes. This refers to most of the equality testing operators 
available in Qt, too
The question is: In which classes do operators make sense, improve the 
intuitiveness/handling and keep the "spirit" of the original Qt roots?
An example would be the __getitem__ operator for QTabWidget or QListBox, 
because they provide item access over indices.
Another example could be using
listbox[1] = "test"
to set the text of QListBoxItems.

(The examples should just give you the scent of the survey and are not 
garanteed to be senseful.)
Just to show what is possible, an (imcomplete) listing of all operators:

Comparison operators:
__eq__ 		==
__ge__ 		>=
__gt__ 		>
__le__ 		<=
__lt__ 		<
__ne__ 		!=
or
__cmp__ 	all-in-one solution, see qstring.sip

Container operators:
__getitem__ 	cont[i]
__setitem__ 	cont[i] = "test"
__delitem__ 	del cont[i]
__len__  	len(cont)
__contains__	i in cont

Arithmetic operators
all of +, -, *, /, ** and their augmented version
__invert__ 	~
all bitwise operator like &, |, ^, <<, >> and their augmented version

Misc:
__nonzero__ 	e.g. for containers to assert non-emptyness or sanity 			 
testing (QDateTime.isValid() for example)
__str__		conversion to python strings
__unicode__	conversion to python unicode string

I'm curious about your suggestions, so feel free to post.

greetings

Torsten
