Custom-type QVariant comparison in KConfigDialogManager

[Constantin Berzan]

Hello list,
I am using a KUrlRequester in a form for configuring a KConfigXT "url" 
property. The problem is that the "Default" and "Apply" buttons are always 
active. I think I got to the root of this problem, which is the way item 
values are compared in kdelibs/kdeui/dialogs/kconfigdialogmanager.cpp on line 
480:

if (p != item->property())

We are comparing two QVariants which (in this case) use the custom "user" type 
KUrl. The Qt docs clearly state we can't do this: operator!= and others don't 
support custom types.

I can't see a way around this problem, so please enlighten me ;)
Many thanks in advance.


Note that the problem disappears if I use strings (and QLineEdits) instead of 
urls (and KUrlRequesters). Obviously because QVariants have no problem with 
that.
