* @brief A timezone selection widget.

* \b Detail:
*
* This class provides for selection of one or more timezones.
*
* \b Example:
*
* To use the class to implement a system timezone selection feature:
* \code
*
* // This adds a timezone widget to a dialog.
* m_timezones = new KTimezoneWidget(this, "Timezones");
* ...
* \endcode
*
* To use the class to implement a multiple-choice custom timezone selector:
* \code
*
* m_timezones = new KTimezoneWidget(this, "Timezones", vcalendarTimezones);
* m_timezones->setSelectionModeExt(TDEListView::Multi);
* ...
* \endcode
