Detailed Description
The Qtitan::PopupMenu is derived from QMenu and should be used in the same cases where regular QMenu is used. Additionally to the QMenu features, this class implements the ability to scroll items vertically if they do not fit completely on the screen or the number of items on the screen is limited by the property - PopupMenu::setMaxItemCount(). Moreover, it allows to display a custom QWidget on the right part from the menu items view which can be used as a preview for the selected item or jsut for additional info for the end-users.
