KDateTable future and KListWidget patch for review

[Robert Knight]

Hello,

I have been doing some work porting a few of the remainding widgets in kdeui
which currently use the Qt3 support classes to Qt4.

Firstly, replacing the Q3ListBox-based KListBox with KListWidget.  I
have never committed anything substantial to kdelibs before, so I
would appreciate it if someone could have a quick look over the
patch before I commit.  It is large I know, but most of the
changes involve refactoring the same usage patterns into others.

My other question concerns KDateTable, which provides the calendar
widget used in the date picker dialog.
In Qt 4.2, Trolltech introduced a QCalendarWidget, which is very
similar in purpose.  I am not sure whether I should port KDateTable to
Qt4 or whether its usage elsewhere should be replaced with
QCalendarWidget.

Regards,
Robert Knight.
