Limitations on kdewidget candidates?

[Shaheed]

Hi all,

I'm wondering why the KTimezoneWidget I added to kdewidgets does not work. It 
shows up in Qt Designer as one might wish, but whenever I try to add an 
instance to a dialog, designer aborts saying:

/usr/lib/qt3/bin/designer-real: symbol lookup 
error: /home/srhaque/kde/lib/kde3/plugins/designer/kdewidgets.so: undefined 
symbol: _ZN15KTimezoneWidgetC1EP7QWidgetPKcP10KTimezones

Of course, looking up the mangled name gives the constructor of the widget, 
but its visibility in libkdeui.so seems the same as any other widget from the 
KDE set. So why the error?

I am wondering if the real reason for the error is that KTimezoneWidget 
constructor takes a KTimezone argument, and *that* is not defined except in 
libkdecore.so: AFAIK, Qt designer knows nothing of that library.

Assuming this reasoning is right, is there a way to workaround this, or do I 
have to remove KTimezoneWidget from kdewidgets?

Thanks, Shaheed
