The CategorySelector widget provides a way to select amongst a group of items.
The CategorySelector is a QWidget having Qt::Tool window hint. That results in representing this widget as a tool window - usually a small window with smaller than usual title bar and decoration. CategorySelector represents the possible selections as a list of check boxes.
Programmer can set the list of possible choice variants using SetPossibleSelections and get selected items with GetSelections.
CategorySelector emits selectionChanged() signal when user changes his selection. CategorySelector's primary purpose is to help user to select tags using a line edit, so there's a convenience function SetSelectionsFromString() which can be used to notify CategorySelector about changes of possible categories. There are also convenience slots selectAll() and selectNone() which could be used to mark all and no elements in the list respectively.

Gets selected items.
Returns the selected items - a subset of selection variants passed via SetPossibleSelections.
